The battery charger (10) has at least one charging port for a device having a rechargeable battery and a charging circuit. The charging circuit includes a DC-DC circuit, a current regulation circuit (CRC) (54), and an output voltage regulation circuit (OVA) (56), the charging port being electrically connected to an output of the CRC (54). The OVA (56) reduces the power consumed by the CRC (54) by suppressing the voltage at the input of the CRC (54) such that the CRC output voltage is sufficient to charge the rechargeable battery when the rechargeable battery is discharged. The OVA (56) increases the input voltage of the CRC (54) as the rechargeable battery is charged.

    电池充电器(10)具有至少一个充电端口和充电电路,充电端口用于具有可充电电池的设备。充电电路包括DC‑DC电路、电流调整电路(CRC)(54)和输出电压调节电路(OVA)(56),充电端口电连接到CRC(54)的输出。OVA(56)通过抑制CRC(54)的输入处的电压以使得当可充电电池放电时CRC输出电压足以对可充电电池进行充电,来减少CRC(54)消耗的功率。随着可充电电池被充电,OVA(56)增大CRC(54)的输入电压。
