Hybrid Vehicle (HV) Battery Pack and Auxiliary Battery

The COROLLA CROSS Hybrid features a high voltage Hybrid Vehicle (HV) battery pack that

contains sealed Nickel Metal Hydride (NiMH) battery modules*1 or Lithium-ion (Li-ion)

battery cells*2.

*1: for Nickel-Metal hydride battery

*2: for Lithium-ion battery

HV Battery Pack

for Nickel-Metal hydride battery:

• 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 28 low voltage (7.2 Volt) NiMH battery modules

connected in series to produce approximately 201.6 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.

area under the rear seat. The metal case is isolated from high voltage and concealed

by carpet covers in the cabin area.

• The HV battery pack consists of 56*1 or 60*2 low voltage (3.7 Volt) Li-ion battery

cells connected in series to produce approximately 207.2*1 or 222.0*2 Volts. Each

Li-ion battery cell is non-spillable and in a sealed case.

• The electrolyte used in the Li-ion battery cells is a flammable organic electrolyte.

The electrolyte is absorbed into the battery cell separator and will not normally leak,

even in a collision.
