HV resistant connecting or branching-off junction box - has insulators on cable ends, and their joints are wrapped with semiconductor potential controlling tapeThe joint box serves at least one incoming and one outgoing cable. It consists of a plastics cylinder with thermoplastics box through which ...
The BJB measures the pack’s current and several high voltages throughout the system. It also measures the isolation between the battery and the chassis.
The RD772BJBTPL8EVB is a battery junction box (BJB) reference design with electrical transport protocol link (ETPL) communication. It is meant for rapid prototyping of a 800 V high-voltage battery management system (HVBMS) hardware and software. This board contains two MC33772C battery sensors...
