Centralised Control Unit

by

The centralized BMS has embedded all general functions (cell Voltage/Temperature/Series Current sensing, cell balancing… ) in a single control module/board, and was widely applied on smaller battery packs for commercial vehicles. The advantage of centralized architecture is reduced electronic component costs without slave PCBs required. Another advantage is accuracy, as centralized BMS use the same … Read more

Master and Slave

by
Illustration of general decentralized BMS system structure.

Decentralized BMS Architecture is split into one main controller and multiple slave PCB boards. Consist of several equal units, which provide the entire functionality locally and autonomously. Each of the individual BMS units is able to operate independently of the remaining ones. Communication lines between the units enable information exchange and task coordination between the … Read more
