Hybrid Vehicle (Hv) Battery Pack And Auxiliary Battery - Toyota Highlander 2006 Manual

Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery

The Highlander hybrid contains a next generation high voltage, Hybrid
Vehicle (HV) battery pack and a low voltage auxiliary battery. The HV
battery pack contains non-spillable, sealed Nickel Metal Hydride
(NiMH) battery modules and the auxiliary battery is a typical
automotive lead-acid type.
HV Battery Pack
•
The HV battery pack is enclosed in a metal case and is rigidly mounted to
the cabin area floor pan cross member under the second row rear seat.
The metal case is isolated from high voltage and concealed by a cover in
the cabin area.
•
The HV battery pack consists of 30 low voltage (9.6-Volt) NiMH battery
modules connected in series to produce approximately 288-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 of
potassium and sodium hydroxide. The electrolyte is absorbed into the
battery cell plates and will form a gel that will not normally leak, even in
a collision.
•
In the unlikely event the battery pack is overcharged, the modules vent
gases directly outside the vehicle through a vent hose.
