Patent ID: 7888914

Claim:
A battery rejuvenation method for rejuvenating a battery, comprising the following steps: (a) pre-charging the battery for a short period of time; (b) detecting the battery voltage and judging whether the battery voltage is higher than a reference voltage value; (c) equalizing the battery with an equalizing voltage based on an equalizing current for a first period of time if it determines that the battery voltage is higher than the reference voltage value in the step (b); (d) reconditioning the battery with a high instantaneous rising pulse current of high peak to peak amplitude and short pulse rising time for a second period of time; (e) equalizing the battery with the equalizing voltage based on the equalizing current, detecting the battery voltage and judging whether the battery voltage is higher than a reference voltage value; (f) maintaining the step (e) for a total period of time equal to the first period of time and then repeat the step (d) if it determines that the battery voltage is higher than the reference voltage value during the step (e), or stopping the step (e) immediately and proceeding to the next step whenever it determines that the battery voltage is not higher than the reference voltage value in step (e); (g) reconditioning the battery with the high instantaneous rising pulse current for a third period of time.
