Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery
The AVALON 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 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 34 low voltage (7.2 Volt) NiMH battery modules connected in
series to produce approximately 244.8 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.
