Embodiment Construction

[0010] see figure 1 , a lithium-ion power supply device for starting a car, comprising a top cover 10, a battery box, a battery cell, a battery protection board and an electrolytic capacitor 20. The battery case is a cuboid structure, and the upper cover 10 is fixedly connected with the battery case. The protective plate and the battery cells are arranged in a closed cuboid formed by the battery case and the upper cover 10 .

[0011] The positive pole 11 and the negative pole 12 are fixed on the upper cover 10 and exposed on the outer surface of the upper cover 10 . The electrolytic capacitor 20 is connected between the positive pole 11 and the negative pole 12 , and is installed in a recess inside the upper cover 10 .

[0012] The battery cell is composed of four lithium-ion single cells connected in series, and each single cell is placed sideways in the battery box.

[0013] The above content is a further detailed description of the present invention in conjunction with s...

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 [0001] The invention relates to an automobile starting power supply, in particular to a lithium ion power supply device for automobile starting. Background technique [0002] At present, the starting power supply of automobiles mainly uses lead-acid batteries. Since the monthly self-discharge rate of lead-acid batteries reaches 30%, it needs to be started every three months (at least 30 minutes), or it has to be driven for a certain distance, otherwise it will run out of power when it needs to be used. The lithium-ion battery has a low self-discharge rate, and after one year of storage, the power can still maintain more than 80%, which is enough to start the car engine. Moreover, the average service life of lead-acid batteries is only about two years, and there are problems of environmental pollution caused by lead and acid. The service life of lithium-ion batteries is at least five years, which reduces the elimination rate and causes less environmental poll...
