    摘要: Disclosed is an apparatus for protecting a secondary battery, in which, when the secondary battery such as a lithium-ion secondary battery is exposed to high temperature exceeding a working range due to a change in external environment, external impacts, and so on, or heated due to spontaneous generation of heat caused by internal defects, the secondary battery is discharged. The apparatus includes a thyristor or transistor having an anode and a cathode connected both terminals of the secondary battery respectively, and shorting both terminals of the secondary battery when gate current is supplied, and a temperature sensor detecting temperature of the secondary battery and supplying the gate current to the thyristor or transistor when the detected temperature is higher than predetermined temperature. Thereby, when the temperature of the secondary battery increases due to any one of a change in external environment, external impacts, heat generation of the battery caused by internal defects, overcharge, and the like, the secondary battery is discharged into a safe state, so that it is possible to prevent the secondary battery from swelling, inflammation, or detonation to thus improving safety.

    摘要: PROBLEM TO BE SOLVED: To provide a battery charger at low cost capable of charging the battery of an own vehicle different in voltage by using a battery mounted in a wrecking car without the need for mounting an exclusive charger.
    SOLUTION: The battery charger 1 comprises the high-voltage battery 10 that stores power; an inverter 12 that converts the power stored in the high-voltage battery 10 to an AC from a DC and outputs it; a motor generator 14 that is driven by AC power outputted from the inverter 12; a reactor 16 that temporarily stores electric energy fed from an external battery 24 when charging the high-voltage battery 10 by the external battery 24, and outputs the stored electric energy to the high-voltage battery 10 via the motor generator 14 and the inverter 12; and an ECU 30 that operates the inverter 12 so that an output voltage of the reactor 16 reaches a voltage necessary for charging the high-voltage 10 when charging.
