Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery

The ES300h 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.
