The equalizer measures the voltage of each of the batteries of the string and then closes a switch in the shunt path associated with the highest voltage battery for a predetermined time. Then the switches of all of the shunt paths are opened and the cycle repeats. In this way, charging is equalized in the batteries of the string, regardless of whether or not any of the batteries of the string is in an over charged condition. | |
