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.
