Battery Management System (BMS) was re-developed in compliance with ISO 26262 ASIL C which is on par with the safety integrity level set by leading car makers. Detailed technical design was derived from holistic high-level safety analyses including HARA, FTA, FMEA, HAZOP, etc. As a result of complying with stateof- the-art engineering practices, the correctness and completeness of requirements, specifications, and technical implementation were verified. The outcome is a significant improvement in quality, reliability, and safety – a hallmark of the automotive electronic control system.
