Hybrid Vehicle (HV) Battery Pack
The HS250h 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 floor pan cross member 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 in a sealed 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 will not normally leak, even in a collision.
