1.2. Kokam Battery Characteristics
1. Advantage of Cell
Kokam manufactures NMC (Nickel manganese cobalt) cell based ESS for most projects. The high energy
density of the NMC cells has a compact design with fewer cells and equipment, as well as ensuring the
required power output. Considering the inherent cost competitiveness of the NMC cells, the NMC based ESS
solution is expected to be satisfactory in terms of pricing. Based on the length of experience and the amount
of references, it is clear that Kokam’s NMC based ESS will deliver and fulfill the technical requirements and
expectations over any other battery chemistry in the market today. The image below shows the characteristics
of two main cells Kokam provided for projects so far.
Cell Chemistry
The large pouch NMC cell has been in Kokam production for approximately 15 years with a manufacturing
process that is both automated and flexible to ensure the highest level of consistency and reliability. The
technology’s exceptional cycle life and high discharge rate capability are attributed to Kokam’s patented cell
construction design, called the Z-fold design. The cell’s parallel pairs of electrodes have very low internal
resistance, contrasted to other competing designs.
Competitiveness of Kokam Battery
A key factor in maintaining the optimum performance of the ESS is to keep the battery cell maintained within
the designed temperature range. The large surface area and thin cross section of Kokam’s large polymerized
Technical Proposal for Global Power Source group September 5th, 2018

aluminum pouch construction allows much more efficient thermal transfer than cylindrical or thick, plastic
coated prismatic cells.
Heat dissipation on cell level
The images above shows the additional surface area and much shorter distance that heat has to travel to exit
the Kokam cells, contrasted to a pouch or competitor’s cell. It shows more than 250% increase of the heat
exchange surface area. The temperature of the competing cell is clearly higher than the Kokam cell, lower
heating characteristic allows for more vigorous operations and longer life.
High Efficiency
Due to the low internal resistance and optimal design for minimizing the loss, Kokam’s Lithium polymer battery
has achieved extremely high efficiency rates (>96.5%) @ 0.5C-rate discharge/charge). The high efficiency of
Kokam’s cells reduces the total operating cost in a battery system.
Round Trip Efficiency of NMC cells
High Power

• Cell: 12C-rate Instant Discharge Possible
• Rack: 10P-rate Instant Discharge and
8P-rate Continuous Discharge
Internal resistance
Kokam’s high power cell has superior lower internal resistance feature. As shown on the graph (left), output
power has improved (in Red) because the internal resistance is lowered about 0.2mΩ overall. As a result,
Lower inner resistance enables the battery to discharge 4C-rate (Continuous Charge), 8C-rate (Continuous
Discharge) and 15C-rate (Instant discharge.)

Kokam’s superior pouch design includes a safety mechanism called tab fusing. The tab acts as a fuse and
disconnects the cell from the load within 3 seconds in the short-circuit event.

functions of the battery system; cell balancing, safety monitoring, and operation control. BMS balances the
cells via passive balancing to maximize capacity and extend cycle life. By monitoring voltage and temperature
at the cell level, there is no oversight of safety as the smallest unit of battery is kept within acceptable
operating conditions. The monitoring software communicates interactively with the user and power system
controllers to provide the available power. In the rare case where cells are subjected to unsafe operating
conditions, there are multiple measures that BMS can take to remove the battery system from the circuit and
protect it from any additional damages. Kokam has extensive experience in the energy storage market to
properly design and implement solutions that guarantees proper hazard analysis and the effective, safe
operation of advanced batteries.
Each Kokam battery module contains a module BMS, which gathers cell-unit voltage and temperature and
transmits them to the rack BMS. Rack BMS gathers the data and analyzes the status of the battery.
Bank/System BMS analyzes the data from the racks to provide real time information on the remaining energy
(state of charge), predictive maintenance/replacement cycles (state of health), and available power of the
batteries. The information is presented to the user via Human Machine Interface (HMI) or PC based software
and to the controller for each of the associated load and power supply, such as a PCS, inverter or charger.
2.3.1. Module BMS
Model Description
• Monitors battery pack voltage and temperature
• Passive Type Cell equalization & Balancing
• CAN communication up to Rack BMS
• Power shut down function
※The image on the left is for reference purposes. The actual product may be different.
Installed into an integrated module BMS housing of the module, the module BMS is at the lowest of the BMS
hierarchy. At the module level, which is the smallest unit system, each and every cell’s voltage and
temperature are measured via module BMS and the module BMS uses these information to calculate the
module voltage. Module BMS also performs the cell equalization and balancing by parameters provided by
the rack BMS (or other upper device).

2.3.2. Rack BMS
Model Description
• Collects information from Module BMS through CAN protocol
• Charge/discharge Current measurement
• Cell High / Low Voltage protection & alarm
• Over Current protection & alarm
• High Temperature alarm & protection
• Automatic shutdown & wakeup (optional)
• Magnetic contactor ON/OFF control
• Single Rack SOC calculation
※The image on the left is for reference purposes. The actual product may be different
All of the information gathered in module level mentioned above in “section 3.6.1 Module BMS” are sent to the
rack BMS. The rack BMS takes this information, then calculates and lets the customer know the battery rack’s
current status including SOC, SOH, power, voltage (rack, min/max cell), and charge / discharge status of the
rack. Furthermore, the rack BMS notifies the user of the fault / alert status including high/low temperature,
voltage, current and communication error. Thus in a rare case when the system goes offline due to a problem,
one can easily identify where the problem occurred and fix the problem.
2.3.3. BMS Monitoring Software
Model Description
• Window-Based PC software
• Monitor various battery data
• Monitor battery faults and alarms
• Modify BMS settings
• Change BMS parameters
• Data logging
※The image on the left is for reference purposes. The actual product may be different
The BMS Monitoring Software is provided with every product equipped with a rack BMS. The software allows
the users to monitor and manage the battery through the rack BMS, without any other software/hardware. By
most design, the BMS communicates all critical information and receives commands from an upper device,
which is usually the inverter. The BMS monitoring software supplements this design by providing another
method of connection to the battery, in case of upper device failure or other faults. This program is
compatible with most Windows-based PC and provides functions to monitor and manage the BMS
independently. After establishing a successful connection with the rack BMS, the software can monitor status
of the battery, read and log individual module and cell level data, assign BMS ID/IP address, modify the BMS
settings, change the BMS parameters, and more. The software is used mostly during commissioning /
acceptance tests and troubleshooting.
