Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery
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 cabin area
floor pan cross member under the second row rear seat. The metal case is isolated from
high voltage and concealed by carpet in the cabin area.
•
The HV battery pack consists of 34 low voltage (7.2 Volt) NiMH battery modules
connected in series to produce approximately 244.8 Volt. 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.
