Embodiment Construction

[0036] See figure 1 , the present invention provides a first preferred embodiment of a lithium-ion automobile starting battery with a supercapacitor function, which includes a power supply, which is formed by connecting a plurality of lithium batteries in series, a supercapacitor, the supercapacitor and the power supply connected in parallel, an overcharge and discharge protection device connected in parallel with the power supply, and a double cycle charging protection system connected in parallel with the supercapacitor.

[0037] The supercapacitor can be used to start the lithium-ion automobile starter battery, so as to realize the high current required by the automobile battery when it is ignited (especially at low temperature). On the one hand, the lithium-ion battery is used to "charge" the supercapacitor, and on the other hand, it provides subsequent current when the supercapacitor's current capacity is insufficient. This double insurance structure makes the lithium-io...

Abstract

The invention provides a lithium-ion automobile starting storage battery with super capacitor function. The storage battery comprises a power supply formed by serially connecting a plurality of lithium battery cells, a super capacitor connected in parallel with the power supply, an over charge and discharge protection circuit device, a double cycle charging protection system, a numerical control voltage feedback multilevel current device and a bidirectional current automatic converter. The storage battery can directly replace the conventional lead-acid automobile starting storage battery and an electronic system of an automobile is not required to be adjusted. The lithium-ion automobile starting storage battery has high starting performance due to a double insurance structure; when a lithium ion battery is charged, a constant-current charger realizes successive constant current and constant voltage function; in addition, the balance problem when high-capacity lithium ion batteries are connected in series is solved, and the standard two-wire system storage battery charge and discharge system of the automobile has the function of a three-wire system of the lithium ion battery.

Description

technical field [0001] The invention relates to a lithium-ion automobile starting storage battery, in particular to a lithium-ion automobile starting storage battery with the function of a supercapacitor. Background technique [0002] Traditional car starting batteries use lead-acid materials, which tend to cause great pollution to the environment during the process of production, scrapping and recycling. In addition, because the lead-acid battery will reduce the voltage as the capacity decreases, the ignition system of the car cannot maintain a stable voltage all the time, thereby increasing fuel consumption. Using lithium-ion batteries to replace the current traditional lead-acid batteries to design automobile starting batteries has the following advantages. First: In view of the strict lead-free requirements for electronic raw materials in automobiles, all materials of lithium-ion automobile starter batteries are non-toxic and non-polluting. Except for some materials of ...
