Problems solved by technology

The tab is the carrier of energy transmission between the battery and the outside world. In order to fix the tab better, the tab connection plate is often used in the prior art to fix the tab, and then the tab connection plate is connected to the circuit board through wires. The structure of the battery has the disadvantages of complex structure, multiple wires inside the battery, wire breakage when shaken, easy short circuit and potential safety hazards.

Embodiment

[0030] Example: such as Figure 1-4 As shown, a battery cell combination includes a chipset 10, an insulating plate 20 and a circuit board 30. The chipset 10 is composed of a number of single battery chips, and each battery chip has an upper end surface 11 and an upper end surface opposite to the upper end surface. The lower end face 12, the insulating plate 20 is covered on the upper end face 11, the circuit board 30 is placed on the insulating plate 20, the upper end face 11 is provided with positive and negative pole lugs 13, the pole lugs 13 Pass through the insulating board 20 and be fixedly connected to the circuit board 30 , the shell of the battery chip is made of hard material, and the tab 13 is copper sheet. In the present invention, the tabs 13 in the battery chip are directly connected to the circuit board 30, which not only omits the tab connection plate in the traditional process, but also does not need to be connected by wires, thus reducing the cost of battery ...

Abstract

The invention relates to a battery cell combination and a battery assembly using the battery cell combination. The battery cell combination comprises a chipset, an insulation board and a circuit board. The chipset is composed of a number of single battery chips. Each battery chip comprises an upper end face and a lower end face opposite to the upper end face. The insulation board covers the upperend face. The circuit board is placed on the insulation board. The upper end face is provided with positive and negative electrode tabs, and the electrode tabs are fixedly connected with the circuit board through the insulation board. The battery cell assembly not only omits a tab fixing plate and an auxiliary connecter between the electrode tabs and the tab fixing plate in the prior art, but alsoomits wire connection between the tab fixing plate and the circuit board, and has the advantages of simple connection process, low cost and high connection strength.

Description

technical field [0001] The invention relates to a battery, in particular to a battery cell assembly and a lithium battery assembly used in an electric vehicle. Background technique [0002] Due to the advantages of high specific energy and long service life of lithium batteries, more and more electric vehicle manufacturers use lithium batteries as the power source of electric vehicles. The tab is the carrier of energy transmission between the battery and the outside world. In order to fix the tab better, the tab connection plate is often used in the prior art to fix the tab, and then the tab connection plate is connected to the circuit board through wires. The structure of the battery has the disadvantages of complex structure, multiple wires inside the battery, which will cause the wires to break when shaken, and easy short circuit and potential safety hazards. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention prov...
