SAFETY CLAMP SYSTEM FOR EMERGENCY START OF VEHICLE BATTERY
First Claim
1. A safety clamp system for an emergency start of a vehicle battery, the safety clamp system electrically connected between an external lithium battery and the vehicle battery, the safety clamp system comprising:
- a boost circuit electrically connected to the external lithium battery;
a voltage-stabilizing circuit electrically connected to the boost circuit;
a control unit electrically connected to the voltage-stabilizing circuit;
a power detection circuit electrically connected to the external lithium battery, the vehicle battery and the control unit;
a battery-clamp-loose detection circuit electrically connected to the vehicle battery and the control unit;
an auto-detect-battery-voltage-and-short-circuit detection circuit electrically connected to the vehicle battery and the control unit;
a driving circuit electrically connected to the boost circuit and the control unit;
a turn-on/off detection circuit electrically connected to the external lithium battery, the vehicle battery and the driving circuit; and
an alarm circuit electrically connected to the control unit,wherein the power detection circuit and the auto-detect-battery-voltage-and-short-circuit detection circuit detect an input voltage and the vehicle battery, and then abnormal detection signals are sent to the control unit;
the control unit controls the driving circuit to drive the turn-on/off detection circuit and the alarm circuit for supplying power and protection;
the battery-clamp-loose detection circuit detects that a battery clamp is loose;
no voltage is sent to the control unit, so that the control unit outputs no signal.

Abstract
A safety clamp system for an emergency start of a vehicle battery comprises a boost circuit, a voltage-stabilizing circuit, a control unit, a power detection circuit, a battery-clamp-loose detection circuit, an alarm circuit, an auto-detect-battery-voltage-and-short-circuit detection circuit, a driving circuit and a turn-on/off detection circuit. The power detection circuit and the auto-detect-battery-voltage-and-short-circuit detection circuit detect whether an input voltage or the vehicle battery is normal or abnormal. If normal, the control unit controls the driving circuit to drive the turn-on/off detection circuit, so that a power supplied by an external lithium battery is sent to the vehicle battery. If abnormal, abnormal detection signals are sent to the control unit to drive the alarm circuit. If a battery clamp is loose, the control unit controls the driving circuit to stop driving the turn-on/off detection circuit, so that the power is not sent to the vehicle battery.
