摘要： 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.

摘要： A battery controlling device includes: a voltage detecting unit configured to detect a closed-circuit voltage of a secondary battery; an open-circuit-voltage computing unit configured to compute an open-circuit voltage of the secondary battery; and an assembled-battery controlling unit configured to discriminate whether a computed value computed based on a voltage difference between the closed-circuit voltage and the open-circuit voltage of the secondary battery in a continuous predetermined period is exceeding a permissible value determined in advance or not. If the computed value is exceeding the permissible value determined in advance, the assembled-battery controlling unit outputs a signal that carries out charge/discharge restriction of the secondary battery.

摘要： A battery control system connected to a battery, which controls charge/discharge at the battery, includes: a current detection unit that measures a current value by detecting a charge/discharge current flowing through the battery; a voltage detection unit that detects a voltage at the battery; a temperature detection unit that detects a temperature at the battery; an effective current value calculation unit that calculates, based upon the current value measured by the current detection unit, an effective current value in a predetermined time window; and a charge/discharge restriction unit that imposes a first charge/discharge restriction so as to restrict the charge/discharge current based upon the effective current value calculated by the effective current value calculation unit.
