Nickel Cadmium battery continues to be most reliable battery systems available as a source of DC power.Its advantageous features enables it to be most preferred battery systems. With the advent of valveregulated lead acid battery, a new concept was available, a battery that did not require waterreplenishment. HBL NIFE on this concept developed the VRPP recombination nickel cadmium pocket platebattery.

VRPP batteries are designed to meet the needs of applications requiring the traditional high reliability ofnickel- cadmium pocket plate cells without the need to top-up with water. They are indeed the bestsolution for installations, whether they are UPS systems, emergency lighting systems, telecommunications,where the risk of failure of the system is unacceptable. VRPP batteries are also eminently suitable forremote applications such as photovoltaic systems, offshore applications and switching substations, wherethe system must have total reliability without the need for battery maintenance.

In a conventional pocket plate nickel cadmium flooded electrolyte battery, water is lost from the battery ono v e r c h a r g e d u e t o t h e f o l l o w i n g r e a c t i o n s :

This corresponds to a theoretical loss of 36 g of water for 107 Ah of overcharge ie., 0.335 cc per Ah.Hence a conventional cell requires periodic addition of water. The frequency of this operation dependsupon the cumulative amount of charge received and the operating temperature.

During charging process evolution of Oxygen begins just before the positive plate is fully charged stateand then becomes the main reaction when the fully charged condition is reached. The cadmium negativeplate has a better charge acceptance than the positive plate. Hydrogen is not evolved until the plate isvirtually fully charged.

The VRPP battery has been designed with an excess of Cadmium active material to enhance this effectand ensure that oxygen commences prior to the hydrogen evolution.

The oxygen which is produced at the positive plate surface is collected by the special porous separator andthus not allowed to escape from the region between the plates. Some displacement of electrolyte withinthe separator occurs, thus generating extra unfilled pores for the diffusion of Oxygen directly to theadjacent cadmium negative plate.

At anode (positive) _ _ 4OH O + 2H O + 4e (Oxygen evolution)2 2


4/272

When Oxygen reaches the negative plate it reacts either chemically:

2Cd +O +2H O 2Cd (OH) .......................12 2 2

OR electrochemically

_ _O + 2H O + 4e 4OH .......................22 2

Reaction 1 has the effect of chemically discharging some of the cadmium to cadmium hydroxide. Thecurrent passing through the battery is used to recharge this material.

Reaction 2 consumes the current directly. Thus the hydrogen evolution at the negative plate issuppressed because the preferred reaction is oxygen recombination. The total process of oxygen generationand consumption is referred to as an oxygen recombination cycle.

The efficiency of this oxygen recombination process depends upon the relationship between the rate atwhich oxygen is produced and the rate at which it can be collected and transferred to the negative platesurface. The rate of collection and transfer of oxygen is controlled by the separator type and the cell design.

The rate at which oxygen is produced on overcharge is directly related to the charge current once thepositive plate has reached a full state of charge. The charge current in turn is controlled by the chargingvoltage level set on the charging equipment and the ambient temperature. By controlling the chargevoltage high efficiencies can be obtained and in this way the rate of water loss can be reduced to a fractionof that from conventional batteries.

Though the efficiency of this oxygen recombination is high it will never achieve 100% as small quantitiesof oxygen will escape from the separator before reaching and reacting at the negative plate. Thus a smallquantity of hydrogen will ultimately be generated and hence a low rate of water loss will occur. The batteryis designed to accommodate this by provision of a generous electrolyte reserve both above and aroundeach cell pack within the battery. This ensures a long service life without the need to top-up with water.

The VRPP battery is fitted with a low pressure vent on each cell, on overcharge the cell have an internalpressure above atmospheric pressure. This vent provides an outlet for the release of small quantities ofhydrogen and non combined oxygen and thus controls the internal pressure. If the pressure falls belowthe release pressure, the vent reseals to prevent air entering inside the cells and minimizes self-dischargereactions.

Battery sizing principles

VRPP is designed to impart an comfortable acquisition for the consumer, based on the performance datagenerated after the cell kept on float for several months

Thus in a situation at normal ambient temperature without any specific requirement with regard torecharge time the published data can be used directly to size the battery. However, if there arerequirements with regard to recharge time or temperature then this will modify the result.

Examples

OA standby system is to be sited in a building with an ambient temperature of 20 C and the temperatureO Owill always lie between 10 C and 30 C. It has a maximum voltage of 54 V and a minimum voltage of 42 V

and requires a back-up of 48 A for 3 hours.

In this case a simple 1.42 V/cell single level charger without temperature compensation can be used.

Number of cells = 54/1.42 = 38 and the final voltage will be 42/38 = 1.105 V/cell.

The Cell performance data shows that the VRPP 156 gives 50.2 A for 3 hours to 1.10 V/cell and so thebattery should be 38 cells of VRPP 156. At this single level voltage and at this temperature the battery wouldgive 20 years without topping-up.

5/273

However, if for this example there was a restriction that the battery must give 90% of its performanceafter 10 hours from a totally discharged state then certain modifications need to be made to the calculation.

If the single level 1.42 V/cell charger is retained, then from the graph 4 it can be seen that after 10 hoursabout 75% of the capacity is available and so the battery size will have to be increased by the factor 90/75or, in other words, 20%. Thus for a current of 57.6 A (48 A + 20 %) to 1.10 V/cell the battery required is38 cells of VRPP 184 as this gives 59.2 A to 1.10V/cell. This battery will still give the 20 years without

topping-up.

From the graph 4 , it can be seen that a voltage of 1.45 V/cell gives 80% of the capacity after 10 hoursis need to increase the cell capacity to compensate for the charge. 90/80 ie., 12.5%, a current of 54 A(48 A + 12.5%). However, the battery has to be recalculated as, with the same voltage window, the highercharge voltage will modify the end of discharge voltage.

Thus, the number of cells = 54/1.45 = 37 and so the end of discharge voltage becomes 42/37 = 1.135 V.The VRPP performance table gives VRPP 212, which can discharge a current of 55.2 A to 1.14 V/cell.Hence, in this case the battery is 37 VRPP 212.

The disadvantage of this solution is that a single level charge of 1.45 V/cell will only give 10 years withoutmaintenance and so to achieve the 20 year maintenance level a two stage charger is required.

The construction of VRPP is based on conventional pocket plate technology by introducing special features

to enhance the low water consumption, by means of recombination cycle.

5.1 Plate Construction

The Nickel Cadmium cell consist of two groups of plates, one containing Nickel Hydroxide (the positive plate)

and other containing Cadmium Hydroxide (the negative plate).

The active material of pocket plate are retained in pockets formed from double perforated nickel-plated

steel strips. These pockets are mechanically linked together, cut to the size corresponding to the plate

width and compressed to the final plate dimension. This process leads to a component which is not only

mechanically robust but also retains its active material within a steel boundary which promotes conductivity

and minimizes electrode swelling.

These plates are then welded to a current carrying busbar which further ensures the mechanical and

electrical stability of the product.

The alkaline electrolyte does not react with steel, which means that the supporting structure of the VRPPbattery stays intact and unchanged for the life of the battery. There is no corrosion and no risk of sudden

death.

The separator is an important feature of the VRPP battery. It is a poly-propylene fibrous material. Using

this separator and plastic spacing ribs, the distance between the plates is carefully controlled to give the

necessary gas retention to provide the level of recombination required. By providing a large spacing

between the positive and negative plates and a generous quantity of electrolyte between plates, the

possibility of thermal runaway is eliminated.

VRPP battery is available in both welded (shown here) and bolted construction.

Polypropylene cell container

The electrolyte used in VRPP battery is a solution of Potassium Hydroxide and Lithium Hydroxide to givethe best performance and life over a wide range of temperature. The electrolyte concentration is such thatit allow the cell to be operated down to -20 deg.C, and it is not necessary to change the electrolyte duringthe life of the cell

It is an important consideration of VRPP, and indeed of all nickel-cadmium batteries, that the electrolyteconcentration does not change during charge and discharge. It retains its ability to transfer ions betweenthe cell plates irrespective of the charge level.

5.6 Cell container

VRPP cells are available in polypropylene containers. The polypropylene container can withstand

mechanical stress, shocks and vibrations. It performs in extreme temperature without losing strength,

insulating well and resists corrosion. The translucent nature of polypropylene allows visual check of

electrolyte. If electrolyte level is less than the minimum indication level, there is a provision to adjust it.

5.5 Venting system

VRPP battery is having a unique venting system. The vent releases the Hydrogen and non combined

Oxygen, when the internal pressure increases more than 0.2 bar. If the internal pressure is less, the

system reseals to prevent the air entering inside the cell.

A flame arresting porous disc is incorporated in the venting system to prevent the possibility of any

external ignitions spreading into the VRPP cell.

7.3 Effect of temperature on performance

Variation of cell performance with the temperature are considered in sizing a battery. Low temperature

operation gives a low performance due to the decrease in conductivity of the electrolyte at low

temperature. The normal recommended operating temperature range is 0 deg. to 40 deg. C.

7.2 Internal resistance

The internal resistance of the cell varies with the type of service and state of charge and is therefore,difficult to define and measure accurately. The most practical value for normal application is the dischargevoltage response to a change in discharge current. The internal resistance per 1/C of a VRPP cell at room5temperature when measured after float charging at normal temperature is 80 milliohms for VRPP 8 toVRPP 50 and 100 milliohms to VRPP 55 to VRPP 744. These figures are for a fully charged cell. For lower

7.4 Short-circuit values

The typical short-circuit value in amperes for an VRPP cell is approximately 15 times the ampere-hour

capacity. The VRPP battery is designed to withstand a short-circuit current of this magnitude for many

minutes without damage.

7.5 Loss due to self discharge

The state of charge of VRPP cells on open circuit slowly decreases with time due to self-discharge. This

decrease is relatively rapid during the first two weeks but then stabilizes to about 2-3% per monthat 20 deg.C.

The self-discharge characteristics of a nickel-cadmium cell are affected by the temperature. At lowtemperatures the charge retention is better than at normal temperature and so the open circuit loss is

reduced. However, the self-dischrage is significantly increased at higher temperatures.

The open circuit loss for VRPP for the standard temperature and the extremes of the normal operatingrange is shown in the graph 2.

It is necessary to recharge the VRPP cells each year.

7.6 Cycling

VRPP is a low maintenance battery used in standby application and not in continuously cycling applications.The battery is designed using conventional pocket plate electrode technology. Therefore it retains thecycling capability of the parent product. The cycling operation requiring deep discharges and fastrecharges involves significant gas evolution and ultra low maintenance properties of the product will be

severely reduced.

7.7 Water consumption

The VRPP battery works on the Oxygen recombination principle and therefore has a much reduced water

consumption. The level of recombination of these cells are 85 - 95%. Normal vented type cells will have

only 30 - 35% recombination efficiency. At suitable charging voltages and temperature the VRPP cell will

not need water topping for a longer time when compared to the conventional vented type Nickel Cadmium

Pocket Plate batteries.

7.8 Gas evolutionThe gas evolution is a function of the amount of water electrolyzed into hydrogen and oxygen which is not

involved in the recombination cycle. The electrolysis of 1 cc of water produces about 2000 cc of gasmixture and this gas mixture is in the proportion of 2/3 hydrogen and 1/3 oxygen. Thus the electrolysis of1 cc of water produces about 1300 cc of hydrogen.

As stated in the previous paragraph, under normal recommended float conditions VRPP has a recombination

level of 85% to 95% and so the amount of water which is electrolyzed into gas is small. Typically an VRPP

cell will electrolyze about 0.002 cc of water per Ah of cell capacity per day. This value will be smaller or

larger depending on the float voltage value. Thus a typical value of gas emission would be 3.5 cc per Ah

of cell capacity per day, or 2.5 cc of hydrogen per Ah of cell capacity per day.

VRPP batteries may be charged by the following methods:

A) Two rate charging:

The initial stage of two rate constant potential charging consists of a first charging stage, with a current

limit of 0.1 C to a maximum voltage of 1.45 V/cell.5

Alternatively, if a faster rate of recharge is required, a voltage limit of 1.55 V/cell can be used. However,

if frequent recharges are required this will increase the rate of water loss.

After this first stage the charger should be switched to a second maintenance stage at a float voltage in

the range of 1.41 to 1.43 V/cell. After a prolonged mains failure the first stage should be reappliedmanually or automatically.

B) Single rate charging:

VRPP batteries may be float charged at 1.41 to 1.43 V/cell from a fully discharged condition to a high

stage of charge. This is detailed in section 7.2 and about 80% of the capacity will be available after 16hours of charge.

Alternatively, VRPP can be float charged at 1.45V/cell if a faster recharge time is required. This will,however, increase the rate of water loss and reduce the maintenance interval by a factor of two.

Temperature compensation may be required as described.

The performance data sheets for VRPP are based upon several months floating and so are for fully float

charged cells.

A discharged cell will take a certain time to achieve this and graph 4 gives the capacity available for the two

principal charging voltages recommended fo VRPP, 1.42 V/cell and 1.45 V/cell, during the first 30 hours of

charge from a fully discharged state.

If the application has a particular recharge time requirement then this must be taken into account when

calculating the battery.

8.1 Charging methods

8.2 Charge acceptance

In order to achieve the ultra low maintenance properties of the VRPP battery, it is necessary to control the

charge input to the battery to minimize the rate of water loss during the life of the product. Therefore it is

VRPP batteries are normally supplied charged, ready for immediate use and provided they have not been

stored for more than six months, they may be put directly into service on float charge. Under these

circumstances they should not be given a commissioning charge before putting into service.

Batteries stored between six and twelve months should be treated as batteries filled and discharged.

8.3 Commissioning requirements

8.3.1 Batteries filled and charged

8.3.2 Batteries filled and discharged

Batteries in a filled and discharged state require a commissioning charge prior to putting into service.

This is a once only operation and is essential to prepare the battery for its long service life.

The commissioning charge requires an input of 160% of the rated (C ) capacity before putting the battery5

into service.

Prolonged overcharging is not harmful to VRPP batteries are normally supplied charged but will reduce

the initial electrolyte reserve and thus service life without topping up.

The following methods of commissioning charge are recommended

a. Charge 16 hours at 0.1 C A maximum.5

b. Charge at 1.65 V/call for 16 hours maximum (0.1 C A current limit)5

If these recommended methods are not available in practice, then charging may be carried out at

lower float voltages for extended periods.


13/2711

9.1 Electrical abuse

Ripple effects

The nickel-cadmium battery is tolerant to high ripple from standard charging systems. VRPP batteries have

been tested with voltage ripple values of up to 15% without any effect on water loss.

Over discharge

If more capacity is drawn out than the rated capacity, the battery is said to be over discharged. This abuse

situation should be avoided. In the case of lead acid batteries this will lead to failure of the battery and is

unacceptable.

The VRPP battery is designed to make recovery from this situation possible.

Over charge

Overcharge of the battery will increase the water loss of the system. In case of VRPP battery, with its

generous electrolyte reserve, a small degree of overcharge will not significantly alter the maintenance period.

In the case of excessive overcharge, a situation which will immediately destroy a valve regulated lead acid

battery, VRPP can be refurbished as described in section 12.

9.2 Mechanical abuse

Shock load

The VRPP block battery concept has been tested as per IEC 68-2-29 (bump tests at 5 g, 10g and 25 g)

and IEC 77 (shock test 3 g).

Vibration resistance

VRPP cells are tested as per IEC 77 for 2 hours at 1 g.

External corrosion

VRPP batteries are manufactured in durable polypropylene, all external metal components are nickel-plated

and these components are protected by a neutral grease and a rigid plastic cover.

14/2712

10.1 Emplacement

The HBL NIFE brand VRPP valve regulated recombination battery can be fitted onto stands, can be floor

mounted or can be fitted into cabinets.

Local standards or codes normally define the mounting arrangements of the batteries, and these must be

followed if applicable. However, if this is not the case the following comments can be used as a guide.

When the battery is housed in a cubicle or enclosed compartment, it is necessary to provide adequate

ventilation depending on utilization.

Allow sufficient space over the battery to ensure easy access during assembly.

HBL NIFE offers a wide selection of stands to suit most applications.

It is desirable to have easy access to all blocks on a stand mounted battery and they should be situated in

a readily available position. Distances between stands, and between stands and walls, should be sufficient

to give good access to the battery.

The overall weight of the battery must be considered and the load bearing on the flooring taken into

account in the selection of the battery accommodation. In case of doubt, please contact HBL NIFE for advice.

When mounting the battery ensure that the cells are correctly interconnected with the appropriate polarity.

The battery connection to load should be with nickel-plated cable lugs.

To avoid accelerated ageing of the plastic due to UV light, batteries should not be exposed to direct

sunlight, UV light sources or strong daylight for prolonged periods.

10.2 Ventilation

Under normal floating conditions the HBL NIFE VRPP battery gives off up to 10 times less gas than aconventional open cell. Thus the need for ventilation is much reduced and in many cases no special

ventilation requirements other than normal room ventilation are required. The quantity of hydorgen given

off is given in section 7.8, Gas evolution. However, if the VRPP battery is commissioned in the final location

or if the maximum recommended charge current of 0.1 C is used then the quantity of gas given off will be5increased.

A typical figure for room ventilation is about 2.5 air changes per hour and under such conditions it is

satisfactory to install 700 watt hours of battery capacity per cubic meter if the final charge current is at

0.1 C A.5

Please refer to ventilation standards and requirements applicable in your country or area.

Care should also be taken with cubicle installations to ensure sufficient ventilation and battery spacing to

prevent overloading and, hence, excess water usage.

10.3 Storage

VRPP batteries are normally supplied filled with electrolyte and charged ready for immediate use. They may

be stored in this condition for up to twelve months from the date of despatch from HBL NIFE.

O OIf batteries are not put into service immediately, they should be stored in a clean, dry cool (+10 C to +30 C)

and well ventilated store on open shelves. They should not be exposed to direct sunlight. Before storageensure that the batteries are clean, with on adequate protective finish, such as an approved neutral grease,

on the connectors, and that the flame-aresting low pressure vents remain undisturbed.

Batteries filled and charged can be stored for up to one year without any conditioning charge requirement.

If they are stored up to six months they should be put directly into service without any commissioningcharge. If they have been stored for between six months and one year they should be given and

commissioning charge as described.

Before putting into service ensure that the batteries are externally clean and with an adequate protective

finish, such as an approved neutral grease, on the connectors.

If it is necessary to store the batteries for more than one year then they should be given the following

conditioning discharge/charge cycle at the end of each year of storage:

- Discharge at 0.1 C A to an end of discharge voltage of 1.1 V/cell, where C is the rated5 5capacity of the battery

- Charge 160% batterys rated capacity at a maximum of 0.1 C A for 16 hours 5

- Return battery to store

- Repeat every 12 months

O OStorage at temperatures above +30 C can result in loss of capacity. This can be as much as 5% per 10 COabove +30 C.

VRPP Battery requires minimum of attention if properly designed for the application. However, it is good

practice with any standby system to carry out a full discharge - charge cycle once per year to make

s u r e t h a t c h a rg e r, b a t t e r y a n d a n c i l l a r y e l e c t r o n i c s a r e f u n c t i o n i n g c o r r e c t l y.

It is recommended that for system servicing, electrolyte levels should be visually checked and ensure

that level is above the minimum, battery should be checked for external cleanliness and if necessary

clean with damp cloth. If there is evidence that electrolyte has been ejected from vents or that there

has been excessive of water this could indicate a charger or system malfunction. Action should be taken

Refurbishment of the VRPP battery is recommended when the electrolyte level reached the normal minimum mark on the cell but must be carried out before it reached the warning level on the cell.

Batteries operated at float charge rates above 1.42 V/cell will require refurbishment during their operating life.

Refurbishing of the VRPP battery is carried out as follows:

1. Disconnect the battery from the load. Remove the terminal cover.

2. With the terminal cover removed, the tops of the individual cells of the VRPP battery will be inview.

3. Confirm that an adequate protective finish remains on glands, poles and connectors. Replenish ifnecessary.

4. Carefully loosen the flame-arresting low pressure vents to release any gas pressure and thenremove each vent completely and retain for refitting.

5. Top-up each cell with distilled or de-ionized water to the specified maximum level.

6. Wipe up any small spillage on cells using a clean cloth. Replace the vents taking care to tightenthem correctly i.e., Until resistance against a stop is experienced, and ensure that the seatingrubber has not been disturbed out of position. If there is any doubt about the quality of the sealingring replace with a new vent assembly.

7. Replace the terminal cover.

The refurbished VRPP battery is now ready for re-commissioning.

Battery arrangement as per rack design

1 step, 1 tier rack

3 step, 1 tier rack

1 step, 2 tier rack

3 step, 2 tier rack

2 step, 1 tier rack

4 step, 1 tier rack

2 step, 2 tier rack

4 step, 2 tier rack

Calculation of length :

length of rack = (x + 5) x no. of block cells in a row ( for all block cells )

Where x = length of cell or block cell for row-wise mounting ( i.e. For B 31, B 32-1, B 41, B 21-1, B 23-1, B 24-1) = width of cell or block cell for cross-wise mounting ( i.e. For B 31-2,3,4 & B 41-2,3,4,5,6 )

The value of length should be rounded-off to nearest to 50 mm and 5mm should be added.

Important changes :

1. For single tier racks lower step gable height increased to 300mm instead of 115mmfor better accessibility of bottom row cells and terminal assembly.

2. But for two tier racks lower step gable height is maintained as 115mm since terminal assembly will be provided on the upper tier.3. Rack legs or side supporters assembled to inside, reducing the width of rack by

angle width.4. The changes have been taken into consideration while calculating above dimension.
