Online PDF Lexus LS600 Hybrid dismantling manual 2008-2009
This guide was developed to educate and assist dismantlers in the safe handling of Lexus LS600h/LS600hL gasoline-electric hybrid vehicles. LS600h/LS600hL 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 pecifications of the Lexus LS600h/LS600hL, as they may not be familiar to dismantlers.
High voltage electricity powers an electric motor, generator, electric inverter compressor (for air conditioner) and power control unit. All other conventional automotive electrical devices such as the headlights, radio, and gauges are powered from a separate 12 auxiliary volt battery. Numerous safeguards have been designed into the LS600h/LS600hL to help ensure the high voltage, approximately 288 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 LS600h/LS600hL identification.
- Major hybrid component locations and descriptions.
By following the information in this guide, dismantlers will be able to handle the LS600h/LS600hL hybrid-electric vehicles as safely as the dismantling of a conventional non-hybrid automobile.
About the LS600h/LS600hL
The LS600h/LS600hL sedan joins the RX400h and GS450h as a hybrid model for Lexus. Lexus Hybrid Drive means that the vehicle contains a gasoline engine and an electric motor for power. The two hybrid power sources are stored on board the vehicle:
- Gasoline stored in the fuel tank for the gasoline engine.
- Electricity stored in a high voltage Hybrid Vehicle (HV) battery pack for the 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 LS600h/LS600hL 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 LS600h/LS600hL operates in various driving modes.
- During light acceleration at low speeds, the vehicle is powered by the 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.
- During full acceleration, such as climbing a hill, both the gasoline engine and the electric motor power the vehicle.
- During deceleration, such as when braking, the vehicle regenerates the kinetic energy from the wheels to produce electricity that recharges the battery pack.
- While the vehicle is stopped, the gasoline engine and electric motor are off, however the vehicle remains on and operational.
