ABSTRACT:
A car-used spare power system quick charging device including a switch, a boosting circuit, a detecting circuit, an indicating circuit, an unstable circuit, a pulse cutting circuit and multiple charging batteries. The detecting circuit serves to detect the voltage state of the charging battery. The indicating circuit serves to indicate the voltage state of the charging battery detected by the detecting circuit. The switch is used to switch the charging/discharging modes. When the charging battery is detected to be in middle or low voltage state, the boosting circuit serves to boost the charging battery into high voltage. The charging battery charges/discharges the car battery by way of pulse so as to protect the charging battery from damage due to over-heating and make the charging battery 100% release voltage.
