Abstract
The battery assembly control system comprises a master controller, a power converter management unit, and power converters. Five battery units are connected in parallel to the charging and discharging main bus of one of the power converters. A switch board, including a plurality of second protection resistors, a plurality of switches, and a first protection resistor, is provided between each of the battery units and the charging and discharging main bus. The second protection resistors have a positive temperature coefficient and have a function of reducing the voltage difference among the four battery pack columns connected in parallel to the sub-bus of each of the battery units. The first protection resistor has a function of preventing excess current.
Claims6
A battery assembly control system comprising:
- a charge/discharge main bus;
- sub-buses connected to the main bus via a first protection resistor;
- and
- units of battery control connected to the sub-buses via second protection resistors, wherein
- the first protection resistor has a resistance value which is constantly or temporarily equal to or greater than a resistance value of the second protection resistor.
