Charging equalizing judgment and supplement device for energy consumption type battery pack

The utility model relates to a charging equalizing judgment and supplement device for an energy consumption type battery pack, which comprises an equalizing unit connected with a single battery and a measuring and controlling unit connected with the battery pack and the single battery, wherein the equalizing unit is used for releasing the voltage of the single battery, which is higher than the preset value; and the measuring and controlling unit is used for measuring and comparing the single battery and judging whether the single battery needs to supplement the energy or not. The utility model has the advantage that the charging equalizing judgment and supplement device is provided with a separate measuring and controlling unit, not only can be separately used for the single battery, but also can be simultaneously used for various single batteries, can be used for shunting and keeping the consistent rate of the voltage of the battery pack and is flexible for use; and in addition, the charging equalizing judgment and supplement device can meet the requirement for charging equalization of industrially-controlled low-capacity battery pack, has a high integration degree and a low cost and is easy for use.
