Abstract

The use of batteries in electrics cars (HEV/PHEV/EV) is becoming the most widespread application of Li-Ion batteries for a number of good reasons. The safety of the (possible) driver and the passengers must, however, be ensured. Due to the characteristics of Li-Ion batteries, inherent risks of injury exist and shall be mitigated in a systematic and documented way. The ISO standard 26262 defines the approach to functional safety requirements for electrical automotive equipment and is applicable throughout the lifecycle of all electronic and electrical safety-related systems. Hence, functional safety features form an integral part of any such automotive product. The requirements of the standard must be considered in the development phase, ranging from the specification, to design, implementation, integration, verification, validation, and all the way to production release. This presentation will give an impression of what is involved in achieving an ISO 26262 certification for a battery management system.
