Abstract
The invention belongs to the technical field of lithium batteries and provides a lithium ion power supply unit for starting of an automobile. The lithium ion power supply unit comprises a battery box, an upper cover and an electrical core arranged in the battery box, wherein the upper cover is provided with positive and negative terminals, the electrical core is composed of a plurality of lithium ion monomers in tandem and parallel connection, and an electrolytic capacitor is bridged over the positive and negative terminals. According to the lithium ion power supply unit for starting of the automobile, a lithium ion battery has good security and a great cycle index; the power supply unit is easy to charge, ripple waves generated by an electric generator are eliminated, and a good voltage stabilization effect is exerted; transient discharge current is great, vehicle voltage is allowed to be smooth and steady, and needs of starting of the automobile are met; high energy conversion efficiency is realized, fuel oil is saved, and emission is reduced.
Description
Technical field
The present invention relates to automobile starting power supply, relate in particular to a kind of automobile starting lithium-ion electric source apparatus.
Background technology
Automobile starting power supply is at present all mainly to use lead-acid battery.Due to the lead-acid battery moon self-discharge rate reach 30%, every three months all will start once (at least wanting 30 minutes), or must drive the segment distance of setting out on a journey, otherwise want the used time just do not had electricity.And lithium ion battery self-discharge rate is low, to place 1 year, electric weight also can maintain more than 80%, is enough to start car engine.And lead-acid battery approximately only has 2 years average life, and there is the problem of plumbous and sour environmental pollution, at least five years useful life of lithium ion battery, minimizing mortality, and also environmental pollution is few.Therefore, using lithium ion battery is an instantly very active research field as automobile starting battery.But the direct current that forms through DC voltage-stabilizing of alternating current that automobile current generator produces, this just inevitably in DC stabilization amount how much with some Alternating Components, this alternating current component being superimposed upon in DC stabilization amount is just referred to as ripple.Ripple is large to lithium ion battery injury in charging process, reduces the cycle life of battery.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of automobile starting lithium-ion electric source apparatus is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of automobile starting lithium-ion electric source apparatus, comprises battery case, upper cover and is arranged on the battery core in battery case, above cover and be provided with positive and negative pole, described battery core is formed by multiple lithium ion single battery core series and parallels; The cross-over connection of described positive and negative electrode intercolumniation has electrochemical capacitor.
Described electrochemical capacitor is fixed on and covers.
In the preferred technical scheme of one, also comprise the battery protecting plate being arranged in described battery case.
Beneficial effect of the present invention: the fail safe of lithium ion battery is good, and cycle-index is many; Make lithium cell charging easy, and can eliminate the ripple that generator produces, and can play good pressure stabilization function; Between Shun, discharging current is large, can make vehicle mounted electric flatten steady, is applicable to the needs of automobile starting; Power conversion high efficiency, and can save fuel oil, reduce discharge.
Brief description of the drawings
Fig. 1 is lithium-ion electric source apparatus schematic diagram for automobile starting according to the preferred embodiment of the invention.
Embodiment
Referring to Fig. 1, a kind of automobile starting lithium-ion electric source apparatus, comprises upper cover 10, battery case, battery core, battery protecting plate and electrochemical capacitor 20.Battery case is rectangular structure, and upper cover 10 is fixedly connected with battery case.Baffle and battery core are arranged in the cuboid of the sealing that battery case and upper cover 10 form.
Positive terminal 11, negative terminal 12 are fixed on upper cover 10, and expose on the outer surface of upper cover 10.Electrochemical capacitor 20 is connected across between positive terminal 11, negative terminal 12, is arranged in the recess of upper cover 10 inner sides.
Battery core is in series by four lithium ion single battery cores, and each monomer battery core is all sidelong in battery case.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, make concrete change or change and all belong to protection scope of the present invention.
