CHARGE ACCEPTANCE LIMIT DETERMINATION DEVICE AND CHARGE ACCEPTANCE LIMIT DETERMINATION METHOD

Provided is a charge acceptance limit determination apparatus capable of correctly determining a charge acceptance limit. The apparatus is characterized by including: a voltage measuring unit 2 that measures a voltage of a secondary battery 1; a current measuring unit 3 that measures an electric current flowing through the secondary battery 1; a determining unit 4 that determines whether or not the secondary battery 1 has reached a charge acceptance limit in accordance with a position on a current-voltage plane of the voltage and the current measured by the voltage measuring unit 2 and the current measuring unit 3.
