Safety features need to be safe and tested

Even safety features like contactors can become a hazard in certain cases. Mercedes-Benz AG recalls 7,996 eSprinter vehicles to the workshop worldwide. In certain eSprinter vehicles manufactured between 2019 and 2021, there may be a loss of drive immediately after starting due to a fault in the battery management system.

Test-cases for battery management systems need to consider all driving scenarios and the total vehicle environment. The basis should be the scenarios derived from the functional safety assessment.
