    The HV battery uses nickel metal-hydride batteries and does not require external charging. The HV control ECU controls the SOC (state of charge) of the HV battery at a constant level during driving. The HV battery is composed of 30 modules, and each module consists of eight 1.2 V cells in series. The battery smart unit monitors battery block voltage at 15 locations. Each battery block is composed of 2 modules in a set.

MONITOR DESCRIPTION

The battery smart unit, which monitors the voltage of the battery blocks, determines that a malfunction has occurred if a voltage difference between the battery blocks exceeds the standard.
