SYSTEM AND METHOD OF BALANCING BATTERY CELL

摘要

A method and system of balancing battery cells are provided that use a data map that includes a balancing duty ratio based on an environment temperature of a battery and the number of balancing target-cells. The method includes measuring, by a temperature sensor, the environment temperature of a battery. In addition, a controller is configured to identify the number of the balancing target-cells and calculate a balancing duty ratio by substituting the environment temperature and the number of the balancing-target cells to the data map. A balancing time is deducted by the controller based on the calculated duty ratio and the corresponding battery cells are balanced by the controller with the calculated duty ratio for the balancing time.

1. A method of balancing battery cells, using a data map including a balancing duty ratio based on an environment temperature of a battery and the number of balancing target-cells, comprising:
measuring, by a temperature sensor, an environment temperature of a battery; identifying, by a controller, the number of the balancing target-cells; calculating, by the controller, a balancing duty ratio by substituting the environment temperature and the number of the balancing-target cells to the data map; deducting, by the controller, a balancing time based on the calculated duty ratio; and balancing, by the controller, the corresponding battery cells with the calculated duty ratio for the balancing time.
