SYSTEM AND METHOD FOR PREVENTING EXCESSIVE CHARGING OR EXCESSIVE DISCHARGING OF BATTERIES

摘要

According to one embodiment of the present invention, the system for preventing excessive charging or excessive discharging of batteries comprises: a voltage detection unit for detecting the magnitude of the voltage flowing through a power-source line which connects a battery and a battery charger for supplying a power source to the battery; a control voltage output unit for comparing the magnitude of the voltage detected via the voltage detection unit with the magnitude of a pre-set reference voltage, and outputting a different control voltage depending on the result of the comparison; and a relay which is connected to the power source line and breaks the connection of the power source line by turning off depending on the control voltage output from the control voltage output unit.
