Foreword

This guide was developed to educate and assist dismantlers in the safe handling of Lexus UX250h/260h

gasoline-electric hybrid vehicles. UX250h/260h dismantling procedures are similar to other

non-hybrid Lexus vehicles with the exception of the high voltage electrical system. It is important to

recognize and understand the high voltage electrical system features and specifications of the Lexus

UX250h/260h, as they may not be familiar to dismantlers.

High voltage electricity powers the front electric motor, rear electric motor (for AWD), generator, Air

Conditioning (A/C) compressor and inverter/converter. All other automotive electrical devices such as

the head lights, radio, and gauges are powered from a separate 12 Volt auxiliary battery. Numerous

safeguards have been designed into the UX250h/260h to help ensure the high voltage, approximately

216 Volt, Nickel Metal Hydride (NiMH) Hybrid Vehicle (HV) battery pack is kept safe and secure in an

accident.

The NiMH HV battery pack contains sealed batteries that are similar to rechargeable batteries used in

some battery operated power tools and other consumer products. The electrolyte is absorbed in the cell

plates and will not normally leak out even if the battery is cracked. In the unlikely event the electrolyte

does leak, it can be easily neutralized with a dilute boric acid solution or vinegar.

High voltage cables, identifiable by orange insulation and connectors, are isolated from the metal chassis

of the vehicle.

Additional topics contained in the guide include:

Lexus UX250h/260h identification.

Major hybrid component locations and descriptions.

By following the information in this guide, dismantlers will be able to handle UX250h/260h

hybrid-electric vehicles as safely as the dismantling of a conventional gasoline engine automobile.

About the UX250h/260h The UX250h/260h 5-door hatchback joins the hybrid model for Lexus. Lexus Hybrid Drive means that the vehicle contains a gasoline engine, a front electric motor and a rear electric motor* for power. The two hybrid power sources are stored on board the vehicle:

1. Gasoline stored in the fuel tank for the gasoline engine. 2. Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack for the

front electric motor and rear electric motor*. The result of combining these two power sources is improved fuel economy and reduced emissions. The gasoline engine also powers an electric generator to recharge the battery pack; unlike a pure all electric vehicle, the UX250h/260h never needs to be recharged from an external electric power source. Depending on the driving conditions one or both sources are used to power the vehicle. The following illustration demonstrates how the UX250h/260h operates in various driving modes. During light acceleration at low speeds, the vehicle is powered by the front electric

motor and rear electric motor*. The gasoline engine is shut off. During normal driving, the vehicle is powered mainly by the gasoline engine.

The gasoline engine also powers the generator to recharge the battery pack and to drive the motor.

During full acceleration, such as climbing a hill, both the gasoline engine, the front

electric motor and rear electric motor* power the vehicle. During deceleration, such as when braking, the vehicle regenerates kinetic energy

from the front wheels to produce electricity that recharges the battery pack. While the vehicle is stopped, the gasoline engine, front electric motor and rear

electric motor* are off, however the vehicle remains on and operational.

Lexus Hybrid Drive Operation Once the READY indicator is illuminated in the instrument cluster, the vehicle may be driven. However, the gasoline engine does not idle like a typical automobile and will start and stop automatically. It is important to recognize and understand the READY indicator provided in the instrument cluster. When illuminated, it informs the driver that the vehicle is on and operational even though the gasoline engine may be off and the engine compartment is silent. Vehicle Operation With the UX250h/260h, the gasoline engine may stop and start at any time while the

READY indicator is on. Never assume that the vehicle is shut off just because the engine is off. Always look for

the READY indicator status. The vehicle is shut off when the READY indicator is off. The vehicle may be powered by:

1. The front electric motor and the rear electric motor (for AWD) only. 2. A combination of both the front electric motor, the rear electric motor (for AWD) and

the gasoline engine.

Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery The UX250h/260h features a high voltage Hybrid Vehicle (HV) battery pack that contains sealed Nickel Metal Hydride (NiMH) battery modules. HV Battery Pack The HV battery pack is enclosed in a metal case and is rigidly mounted to the cabin area

under the rear seat. The metal case is isolated from high voltage and concealed by carpet in the cabin area.

The HV battery pack consists of 30 low voltage (7.2 Volt) NiMH battery modules

connected in series to produce approximately 216 Volts. Each NiMH battery module is non-spillable and sealed in a metal case.

The electrolyte used in the NiMH battery module is an alkaline mixture of potassium and

sodium hydroxide. The electrolyte is absorbed into the battery cell plates and will not normally leak, even in a collision.

High Voltage Safety The HV battery pack powers the high voltage electrical system with DC electricity. Positive and negative orange colored high voltage power cables are routed from the battery pack, under the vehicle floor pan, to the inverter/converter. The inverter/converter contains a circuit that boosts the HV battery voltage from 216 to 650 Volts DC. The inverter/converter creates 3-phase AC to power the motor. Power cables are routed from the inverter/converter to each high voltage component (front electric motor, rear electric motor (for AWD), electric generator, and A/C compressor). The following systems are intended to help keep occupants in the vehicle and emergency responders safe from high voltage electricity: High Voltage Safety System A high voltage fuse * provides short circuit protection in the HV battery pack. Positive and negative high voltage power cables * connected to the HV battery pack are

controlled by 12 Volt normally open relays *. When the vehicle is shut off, the relays stop electrical flow from leaving the HV battery pack.

WARNING: ・ The high voltage system may remain powered for up to 10

minutes after the vehicle is shut off or disabled. To prevent serious injury or death from severe burns or electric shock, avoid touching, cutting, or breaching any orange high voltage power cable or high voltage component.

Both positive and negative power cables * are insulated from the metal body. High

voltage electricity flows through these cables and not through the metal vehicle body. The metal vehicle body is safe to touch because it is insulated from the high voltage components.

A ground fault monitor in the hybrid vehicle computer * continuously monitors for high

voltage leakage to the metal chassis while the vehicle is running. If a malfunction is

detected, the hybrid vehicle computer * will illuminate the master warning light in the instrument cluster and a message indicating that the hybrid system is malfunctioning will be displayed on the multi-information display.

The HV battery pack relays will automatically open to stop electrical flow in a collision

sufficient to activate the SRS. *Numbers apply to the illustration on the following page.

Precaution to be observed when dismantling the vehicle

WARNING:

・ The high voltage system may remain powered for up to 10

minutes after the vehicle is shut off or disabled. To prevent

serious injury or death from severe burns or electric shock,

avoid touching, cutting, or breaching any orange high voltage

power cable or high voltage component.

Necessary Items Protective clothing such as insulated gloves (electrically insulated), rubber gloves, safety goggles,

and safety shoes. Insulating tape such as electrical tape that has a suitable electrical insulation rating. Before wearing insulated gloves, make sure that they are not cracked, ruptured, torn, or damaged in

any way. Do not wear wet insulated gloves. An electrical tester that is capable of measuring DC 750 Volts or more.

Spills

The UX250h/260h contains the same common automotive fluids used in other non-hybrid Lexus

vehicles, with the exception of the NiMH electrolyte used in the HV battery pack. The NiMH battery

electrolyte is a caustic alkaline (pH 13.5) that is damaging to human tissues. The electrolyte, however,

is absorbed in the cell plates and will not normally spill or leak out even if a battery module is cracked.

A catastrophic crash that would breach both the metal battery pack case and a metal battery module

would be a rare occurrence.

A caustic alkaline is at the opposite end of the pH scale from a strong acid. A safe (neutral) substance

is approximately in the middle of this scale. Adding a weak acidic mixture, such as a dilute boric acid

solution or vinegar, to the caustic alkaline electrolyte will cause the electrolyte to be neutralized. This

is similar but opposite to the use of baking soda to neutralize a lead-acid battery electrolyte spill.

A Lexus Product Safety Data Sheets (PSDS) is attached to this document.

Handle NiMH electrolyte spills using the following Personal Protective Equipment (PPE):

• Splash shield or safety goggles. Fold down helmet shields are not acceptable for acid or

electrolyte spills.

• Rubber, latex or nitrile gloves.

• Apron suitable for alkaline.

• Rubber boots.

Neutralize NiMH electrolyte.

• Use a boric acid solution or vinegar.

• Boric acid solution - 800 grams boric acid to 20 liters water or 5.5 ounces boric acid to 1

gallon of water.
