HYBRID VEHICLE (HV) BATTERY PACK
The LS 600hL 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 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 20 low voltage
(14.4 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.
