WATTALPS modular battery system is certified according to ISO 26262 safety standard!

ISO 26262 is an automotive standard for the functional safety of electric and electronic components. For WATTALPS, it is confirmation of the high quality work done on the 5 year development of its Battery Management System (BMS). The BMS is the electronic brain of the battery and it ensures the battery remains within a safe operation zone.

Over the course of 4 years, Bruno Majot of TECRIS assessed WATTALPS’ development processes and checked that all requirements of ISO 26262 were fulfilled by the team before this was confirmed in a final assessment in March 2023. Bruno Majot is a key contributor to the implementation of ISO 26262 standard in France and is a renowned and active member of SIA (French Society of Automotive Engineers).
