摘要： A self-adaptable recharger includes a control circuit connected to a power-supply circuit, a current-sampling circuit and a pulse-based recharge circuit. The control circuit includes a microprocessor. The pulse-based recharge circuit includes parallel recharge branches each under control of a pin of the microprocessor. The microprocessor receives voltage-related and current-related signals from each of the recharge branches and compares the same with basic data stored therein to determine the types of batteries. The microprocessor calculates time-related changes in the voltage-related and current-related signals and a voltage difference between positive and zero pulses to determine the recharge status and correct recharging curves accordingly. The microprocessor determines the highest recharge voltage, a positive slope of voltage, a zero gain of voltage, a negative gain of voltage and a capacity gain to determine an energy level in each of the batteries and stops the recharge when the battery is full.
