Hybrid Vehicle (Hv) Battery Pack - Lexus GS450h Manual

Hybrid Vehicle (HV) Battery Pack

The GS450h 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 trunk area behind the rear seat. The metal case is
isolated from high voltage and concealed by fabric covers in the
trunk.
•
The HV battery pack consists of 40 low voltage (7.2 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.
