Multichannel accumulator charger capable of setting smart mode of restoring program

Abstract

Disclosed is a multichannel accumulator charger capable of setting a smart mode of a restoring program. The multichannel accumulator charger capable of setting the smart mode of the restoring program comprises an AC / DC (alternating current / direct current) module of an AC power supply input circuit, used to rectify AC power supply or DC high voltage power supply into stable direct current power supply for a rear circuit, an isolated charging power source module used to supply electric energy of a power source for all accumulators through a PWM (pulse width modulation) switching circuit so as to charge all the accumulators, and transfer and physically isolate energy of a power grid source of an input power source and a battery power network and a multichannel voltage detection circuit used to detect charging voltage and feedback of all the accumulators corresponding to all channels. When a charging current, voltage and charging time of a certain accumulator accumulate to preset values, the certain accumulator is completely charged, and then an intelligent charging management control module stops charging the certain accumulator.

Description

technical field [0001] The invention relates to a multi-channel charger for a single storage battery with a repair program intelligent mode, which is used in the daily use of repair, maintenance and maintenance during the charging process of a storage battery composed of a large capacity and a plurality of storage batteries connected in series or in parallel, belonging to the battery Power application technology field.
