The utility model provides a battery equalizing charge adjusts and data acquisition device, includes power supply unit and consecutive central control unit, data acquisition equalizing charge mode selected cell and output unit, data acquisition equalizing charge mode selected cell links to each other with the data acquisition unit, central control unit links to each other with battery status detecting element and data acquisition unit, the power supply unit is continuous with other unit respectively. The device detects battery operating condition, carries out equalizing charge to the battery and adjusts or data acquisition: the battery is at quiescent condition, and equalizing charge solves under the charge mode every section battery cell unbalanced problem of charging, overcomes to worsen the actual capacity that leads to and last the problem that drops because of the battery cell uniformity lasts, the battery is when charged state or discharge condition, and collecting record deposits storage battery each item parameter, forms complete charging or discharge data, the maintenance work volume of avoiding the manual work to discharge and check the battery capacity during operation, extension battery life.
