Hybrid Vehicle (HV) Battery Pack
The Highlander hybrid 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 floor pan cross member under the second row 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 (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 mixture of
potassium and sodium hydroxide. The electrolyte is absorbed into the
battery cell plates and will not normally leak, even in a collision.
In the unlikely event that the battery pack is overcharged, the modules vent
gases directly outside the vehicle through a vent hose.
