Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

A lithium-ion power battery charging device includes a power supply, a lithium-ion power battery, a power supply component and an insulating partition, the power supply is provided with a plurality of constant voltage output terminals; the lithium-ion power battery includes a casing, a copper-aluminum composite board and a plurality of batteries Single unit, the copper-aluminum composite board is provided with a discharge terminal and a plurality of charging terminals, the charging terminal is electrically connected to the battery cell; Pads and multiple conductive patches, the conductive patches are electrically connected to the constant voltage output terminals; multiple separation grooves are opened on the insulating partition, and the contact rods are pierced through the separation grooves, and the power supply is connected to each battery cell through the power supply component. Make each battery cell on the lithium-ion power battery have an independent charging circuit, realize separate charging for the battery elevator, improve charging efficiency, and ensure that each battery cell on the lithium-ion power battery is fully charged and fully discharged, improving the lithium-ion power battery. actual available power.

Description

technical field [0001] The invention relates to the field of lithium-ion power battery charging, in particular to a lithium-ion power battery charging device for the lithium-ion power battery. Background technique [0002] The power battery is the power source that provides the power source for the tool, and mostly refers to the battery that provides power for electric vehicles, electric trains, electric bicycles, and golf carts. Due to the large power capacity and high voltage required by power batteries, the battery packs are composed of several to hundreds of battery cells connected in series. During the production process of lithium batteries, lithium batteries need to be packaged into groups to form lithium batteries. For battery modules, when testing the electrical performance of lithium battery modules, it often occurs that the voltage of individual batteries is low, or when the battery pack is newly assembled, it will be passively balanced at the same voltage by the ...
