Circuit/System Description

The system contains twenty battery modules. Each module contains two 7.2 V cells for a total nominal system voltage of 288 V. Each battery

module is rated at 14.4 V direct current (DC) and all the modules are connected together in series. The drive motor generator battery is also referred

to as the hybrid battery. The drive motor generator battery control module is also referred to as the battery energy control module (BECM). The

drive motor generator battery control module monitors the hybrid battery voltage on the twenty battery modules. The drive motor generator battery

control module determines the actual terminal voltage by monitoring the output voltage from the high voltage contactors.
