These include performance and durability requirements for industrial batteries, electric vehicle (EV) batteries, and light means of transport (LMT) batteries; safety standards for stationary battery energy storage systems (SBESS); and information requirements on SOH and expected lifetime.
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.
In addition to improving the safety and reliability of battery systems, advances in battery state estimation, power optimization, and the user interface experience are of great significance for the next generation of BMS.
A number of problems have recently arisen as a result of unintentional burning and blasting of electric vehicles. Battery management systems, which are the primary safeguards of a battery system for machine electrification and electric propulsion , also face critical challenges for LIBs .
