Black BPMU Rendering

Battery Power Management Unit

The BPMU monitors and reports system status, communicating with each component in the system and enacting controls as directed by the operator. Multiple safety features have been included in the design of the BPMU, including Isolation Detection, system charging self-protection, and numerous status warnings and messages relating to safe operation of high voltage propulsion batteries.

Midpoint Disconect

Midpoint Disconnect

The MPD contains an electrical contactor and the system high voltage fuse. The fuse may be manually removed to reduce effective battery string voltage for safe handling and maintenance operations.
