HYBRID VEHICLE (HV) BATTERY PACK
The GS450h contains 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 securely mounted in the luggage
compartment area behind the rear seat.
The metal case is isolated from high voltage
and concealed by fabric covers.
•
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 plastic 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 forms a gel that
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.
