Sourcing and delivery under one contract
MP-BCU collects measurements, estimates SOC/SOH/SOE, processes alarms and communicates with the energy system. The manufacturer supports Bootloader, OTA or CAN updates. Integration with monitoring modules and external power protection requires a BMS design. The ambiguous LIN entry listing 10/100 Mbit/s has not been treated as a confirmed specification.
