These components collectively form the high-voltage part of a BMS, enabling precise monitoring, control, and protection of the high-voltage battery pack in applications like electric vehicles or large-scale energy storage systems. For battery-internal communication, the HVBMS reference design offers two possible architectures: isolated electrical transport protocol link (ETPL) or CAN/CAN FD. The CMU board features four of our latest ASIL D compliant battery cell controllers (BCC), together monitoring and balancing up to 56. The electrical system within a battery pack performs a core function of connecting all of the battery cells together and out to the main pack positive and negative connections. It also has a number of other functions as we need to think about, primarily safety. This technology not only mitigates the intermittency issues associated with renewables but also supports grid.
