摘要（英）：

The utility model relates to an automobile battery charger. The output end of the rectifying block of the automobile battery charger is connected with the positive electrode of a resistor, controlled silicon SCR1 and the positive electrode of a diode D1. A resistor R3 is series connected in the branch circuit of the D1. A resistor R1, a resistor R2 and the negative electrode of a diode D2 have a conjunct node. A resistor R3 is connected with the negative electrode of the controlled silicon SCR1 and the positive electrode of a capacitor. The control electrode of the SCR1 is connected with the positive electrode of the diode D2. The other end of the resistor R2 is connected with the positive electrode of the controlled silicon SCR2. The negative electrode of the controlled silicon SCR2 is connected with the other output end of rectifying block and the negative electrodes of a displaying part and a battery. The utility model can avoid the damage of the battery caused by over-charging of heavy current and can prolong the service life of the battery.
