摘要
A lithium-ion auto startup storage battery with a supercapacitor function, includes a power supply, composed of a plurality of lithium batteries connected with each other in series; a supercapacitor connected with the power supply in parallel; an over charge-discharge protection device connected with the power supply in parallel; and a double-loop charge-protection system connected with the supercapacitor in parallel, which includes an inner loop circuit and an outer loop circuit, so that a constant current charger achieves firstly a constant current and then a constant voltage when the lithium-ion battery is charged. The present invention further includes a digital control voltage feedback multilevel current device to resolve an equilibrium problem of connecting large-capacity lithium-ion batteries in series. The present invention further includes a bidirectional current automatic converter to make a standard two-wire battery charge and discharge system of automobile achieve a three-wire system function of lithium-ion battery.
