Abstract
A battery control system connected to a battery equipped with an explosion-proofing mechanism for cutting off an electric current when the battery enters an overcharge state, including: a cell voltage detection unit that detects voltage at the battery; a storage unit that stores information pertaining to the battery conditions; an overcharge decision-making unit that makes a decision as to whether or not the battery is in an overcharge state; a storage control unit that engages the storage unit to store information pertaining to the overcharge state when the overcharge decision-making unit decides that the battery is in an overcharge state; and an explosion-proofing decision-making unit that decides that the explosion-proofing mechanism in the battery has actuated if the overcharge information is stored in the storage unit and the cell voltage detected by the cell voltage detection unit is lower than a predetermined lower limit value.
