Countless Applications

HIGH VOLTAGE

While a vehicle’s power system sees a battery pack as a single, high-voltage battery—charging and discharging the entire battery pack at once— the battery management system must consider each cell group’s condition independently.

LOW VOLTAGE

The Stafl Systems BMS will continuously monitor important battery parameters for low voltage applications, while handling the varying power demands of the different operations and optimizing the usage of the battery.

LARGE SCALE SYSTEMS

The service life of a battery pack is tied to the weakest cell group in the system. In the balancing process, each of the cells within the string is maintained at optimal voltage levels, maximizing battery pack performance and cycle life.
