from chemistry to pack
Most explanations of a battery management system, including our own BMS overview, describe it stage by stage: here’s how coulomb counting works, here’s how a contactor gets driven, here’s what isolation resistance means This is useful, but it leaves out something engineers actually have to design: the order these pieces run in, and what gets … Read more
As a vehicle level systems engineer who spent many years working with an HV battery team, I naturally have some thoughts about opening and closing of control contactors. Here is my starter for 10 on the topic of ‘Control contactors’ 😇 Contactor Control is another one of those areas where responsibility is divided between a … Read more
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
