01. Functional Safety Standards (ISO 26262) Functional safety standards ensure that safety-related functionality in Battery Management Systems (BMS) is maintained throughout its lifecycle, mitigating risks that could compromise the system’s reliability and safety.
These safety risks are unacceptable for users, and therefore require specific measures to be taken to reduce the risk. This application note describes a battery management system (BMS) architecture solution with functional safety according to ISO 13849.
Accuracy, response time, and robustness are three crucial performance criteria for a BMS that are covered in this section. Accuracy within a Battery Management System (BMS) signifies the system's capacity to deliver exact measurements and maintain control.
primary system are vital for the battery system’s performance optimization. BMS can accordingly. Sometimes, its main system structure may need to change the working strategy according to the battery’s performance. In such a case, BMS is the only thing battery pack. 2.4. T esting
