Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery

The UX250h/260h 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
under the rear seat. The metal case is isolated from high voltage and concealed by carpet
in the cabin area.

The HV battery pack consists of 30 low voltage (7.2 Volt) NiMH battery modules
connected in series to produce approximately 216 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.
