Abstract

The invention relates to a device which realizes pulse-free transformer voltage-reduction by a pulse-width modulation voltage-reduction mode to enable the efficiency of a charger to be enhanced. A quick charger induces short-time discharge pulse during charging in order to enhance the charging current receptance and achieves the quick charging purpose by depolarization; in the prior art, the discharge current is consumed and wasted uselessly, but the device absorbs the energy of pulse discharged by a storage capacitor and feeds back the energy to a charging circuit to realize back discharge, thereby enhancing the energy utilization efficiency and achieving the dual purposes of quick charge and energy saving. The essential resistance, the voltage and the temperature parameter of a storage battery are detected online in real time, fed back to an intelligent control part of the charger and used for judging the charged state and safety condition of the storage battery to continuously adjust the charging strategy so as to form a complete closed-loop control till the storage battery is charged fully. A safe (i.e. protective measures during charging the storage battery are safe), quick, efficient and intelligent charging process is realized.
