Mobile BMS
Battery Management System for mobile Applications
Downloads
Our Battery Management System is specifically designed for on- and off highway vehicles with large high voltage batteries.
We use Dynamic Cell Balancing (DCB) and String Management for precise monitoring and extendend cycle life of all common cell chemistries and topologies.
Our mobile BMS is designed to meet functional safety requirements according to DIN EN 61508 and ISO 26262.
