U5 (UNIT5) is a German / Swiss network of OEM developers.
Most of the members have been devoting their time and energy to the field of
battery management for decades. Since passive battery management systems have
many huge disadvantages.
This technological idea equalizing
strong cells to weak cells with resistors has led to a heat
dilemma. To increase efficiency of passive battery management system,
stronger resistors were used, which led to a higher heat building-up
Moreover, these battery management systems only worked during
the topping phases, which could last several nights. During operations, these
management systems only rely on measurements; an intervention was and still is
not possible. Even today, most battery management systems run on this
The U5 Active BMS
eliminates this shortfall and opens up new perspectives
powerful and more efficient storage systems.
