Lithium battery management system

Design of a customized Battery Management System (BMS): charger, balancing, limitation of charge and discharge currents. The system is integrated in the air sampling cases, which have a demanding environment, especially on construction sites. We manufacture and support these systems.

Work done

Electronic design, schematic and routing
Embedded software development
Production to replace the original BMS provided by the cell manufacturer
Support and after sales service

Technologies used

Control and limitation of charge and discharge currents
Passive balancing of the cells
Safety devices: short circuit, overload, underload
Low power consumption deep sleep (<13µA)
