For example, general equalizing circuit, its equalizing circuit consumes the energy that overcharges in the charging process by resistance, thereby produces a large amount of heat energy, consequently causes the service behaviour of the battery that is recharged or super capacitor and working life to descend.
Another kind of charge equalization method is that the energy that overcharges in the charging process is moved compensation by equalizing circuit between the monomer of series battery or series capacitance group.This method brings system's lead-in wire to intersect too much, thereby produces the system insulation security problems.
Summary of the invention:
The object of the present invention is to provide the method and the device of the semiconductor refrigeration type equalizing charge of a kind of series battery or serial connected super capacitance group monomer, the energy that overcharges wherein to the charging of cell or super capacitor the time is used for refrigeration, thereby improve the service behaviour and the working life of battery and super capacitor, improve the effective rate of utilization of rechargeable energy.
Technical solution of the present invention is a kind of semiconductor refrigeration type balanced charging method, the series battery of being made up of a plurality of batteries or super capacitor becomes series connection super capacitor group to connect charging with power supply, each cell or super capacitor two ends semiconductor refrigeration type charge balancing circuit in parallel, circuit comes balanced single battery or super capacitor charging by the branch current of regulating charging, overcharging stream in the charge balancing circuit is by semiconductor cooler refrigeration, cool off this circuit battery or electric capacity in parallel.
