What is battery safety management (BSM)?

The Battery Safety Management (BSM) has been developed following the requirements of ISO 26262 ASIL C for functional safety. The battery system is seen as a “System Out Of Context” so as to be integrated in different possible applications. The WATTALPS BSM includes the capacity to open the main battery contactors to put the battery in a safe state.
