Typical System Diagram
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 control system must consider each battery’s condition independently.
COUNTLESS APPLICATIONS
LOW VOLTAGE
A proper system will continuously monitor important battery parameters for low voltage applications, while dealing with the varying power demands of the many aspects of operation and optimizing the usage of the battery.
stationary storage
The service life of a battery pack is tied to the weakest battery in the system. In the balancing process, each of the batteries within the string is maintained at optimal voltage levels, eliminating the ill-effects of improper charging.
