Lexus KMA10 Series Dismantling Manual page 2

Foreword
This guide was developed to educate and assist dismantlers in the safe handling of Lexus UX300e electric
vehicles. UX300e dismantling procedures are similar to other non-electric 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 UX300e electric vehicle, as they may
not be familiar to dismantlers.
High voltage electricity powers the compressor with motor assembly, electric motor, DC/DC converter,
electric heater, and inverter with converter assembly. All other conventional automotive electrical
devices such as the head lights, radio, and gauges are powered from a separate 12 V auxiliary battery.
Numerous safeguards have been designed into the UX300e to help ensure the high voltage, approximately
355.2 V, Lithium-ion (Li-ion) traction battery assembly is kept safe and secure in an accident.
The Li-ion traction battery assembly 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.
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 UX300e identification.
•
Major electric vehicle component locations and descriptions.
By following the information in this guide, dismantlers will be able to handle UX300e electric vehicles as
safely as the dismantling of a conventional non-electric automobile.
