CONSTRUCTION
A battery voltage sensor is optimally positioned in the upper part of the No. 1 HV supply stack sub-assembly and the upper part of the No. 2 HV supply stack sub-assembly. As a result, a small HV battery is achieved.

OPERATION
The battery voltage sensor is connected to the battery ECU assembly via a communication wire and sends information required for calculations performed by the hybrid vehicle control ECU assembly, such as the voltages of the No. 1 HV supply stack sub-assembly and No. 2 HV supply stack sub-assembly, to the battery ECU assembly.
