Foreword
This guide was developed to educate and assist dismantlers in the safe handling of Toyota C-HR Hybrid
gasoline-electric hybrid vehicles. C-HR Hybrid dismantling procedures are similar to other non-hybrid
Toyota 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 Toyota C-HR Hybrid,
as they may not be familiar to dismantlers.
High voltage electricity powers the electric motor, 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 C-HR Hybrid to help ensure the high voltage, approximately 201.6 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:
Toyota C-HR Hybrid identification.
Major hybrid component locations and descriptions.
By following the information in this guide, dismantlers will be able to handle C-HR Hybrid
hybrid-electric vehicles as safely as the dismantling of a conventional gasoline engine automobile.
