    摘要: A method for recycling a battery pack is provided that enables a degraded battery pack to be replaced at a low cost while maintaining the advantages of a conventional sealed-type nickel-metal hydride secondary battery as being free from maintenance or leak of an electrolyte. The battery pack accommodates a battery module having a plurality of cells, which are a sealed-type nickel-metal hydride secondary battery, combined with each other. When the battery pack is judged as being degraded in a market, the battery pack is collected from the market as a battery to be replaced; a cell or battery module judged as being degraded is renewed by adding an electrolyte thereto; the battery module is installed in the battery pack again; and the battery pack is supplied as a replacement battery.

    摘要: An over-charge determining circuit provided for every unit cell generates, a cell over-charge detection signal which becomes high level when a cell voltage is higher than an upper limit value of an allowable voltage range thereof which is set as the threshold value voltage. The threshold value voltage is changed to a lower limit value of the allowable voltage range with which the cell over-charge detection signal surely becomes high level. Even when an output of an AND circuit for obtaining a logical product of the cell over-charge detection signals should become high, if an over-charge determining circuit of which output is fixed to the low level due to a fault of the like exists, the output of the AND circuit becomes low.
