Overcharge protection apparatus with minimized power consumption
Disclosed herein is an overcharge protection apparatus with minimized power consumption. An overcharge protection apparatus with minimized power consumption according to an embodiment includes a switching unit for controlling supply of voltage detected in a battery cell depending on an ignition-on or off state of a vehicle, and an overcharge prevention circuit for, when the battery cell is overcharged based on the voltage of the battery cell output from the switching unit, turning off a main relay, thus interrupting supply of power to a battery module, so that the voltage of the battery cell is detected only in an ignition-on state of a vehicle and power consumption is minimized, thus preventing the lifespan of a battery from being shortened by reducing a voltage difference between cells.
