Problems solved by technology

The heater in this application is in direct contact with the lower end of the battery cells, which improves the heating efficiency of the battery module to a certain extent; however, since the heater is located at the bottom of the battery and the cells are closely arranged, the heater can The heat distribution during the battery heating process is uneven; the peripheral battery cells are heated quickly, while the internal battery cells are heated slowly; and this type of battery module heating device has a complex structure and takes up a large space, which greatly improves the efficiency of new energy batteries. The size is not conducive to the promotion and application of electric vehicles

Embodiment 1

[0058] Embodiment 1: as figure 1 As shown, a new energy button battery pack includes a number of unit battery modules 2 sequentially connected in series through a connecting plate 1 .

[0059] like Figure 6 As shown, the unit battery module includes a battery box 3 and a plurality of batteries 5 positioned and installed in the battery box in a matrix arrangement. The battery of this embodiment is a cylindrical lithium battery.

[0060] like figure 1 , figure 2 , image 3 As shown, the battery box includes a lower box body 3.1 and an upper box body 3.2, and the upper box body and the lower box body are connected by buckles. There are several ventilation holes on the side of the battery box. The top surface and the bottom surface of the battery box are all provided with the extreme connecting holes 4 corresponding to the extremes of the battery one by one, specifically, the top surface of the upper box body and the bottom surface of the lower box body are all provided wi...

Embodiment 2

[0074] Embodiment 2: The specific structure of the new energy button battery pack of this embodiment refers to Embodiment 1, the difference is that:

[0075] like Figure 8 , Figure 9 As shown, the new energy button battery pack also includes several self-adaptive separation devices 1.7 arranged on the conductive plate. The two conductive plates are connected by riveting through a riveting structure.

[0076]An elastic electrical connection piece 1.6 for electrically connecting the two conductive plates is also provided in the heating plate accommodation chamber. The elastic electrical connecting piece is in Z shape. One end of the elastic electrical connecting piece is fixed on the bottom surface of the heating plate receiving groove of one conductive plate, and the other end of the elastic electrical connecting piece elastically abuts against the bottom surface of the heating plate receiving groove of the other conductive plate.

[0077] The riveting structure includes ...

Abstract

The invention discloses a new energy button battery pack, and aims to provide a convenient connection and high production efficiency new energy button battery pack, wherein the service life of the newenergy button battery pack is improved due to the connection stability of connection plates between battery packs is good. The new energy button battery pack comprises a plurality of unit battery modules which are connected in series through the connecting plates in turn, wherein each unit battery module comprises a battery box and a plurality of batteries arranged in a matrix arrangement mannerin the battery box, wherein the top and bottom surfaces of the battery box are provided with electrode end connection holes in one-to-one correspondence with battery electrode ends. Each connecting plate comprises two conductive sheets and a conductive plate between the two conductive sheets, the two conductive sheets are electrically connected, and the conductive sheets are provided with a plurality of electrical contacts that protrude from the sides of the conductive sheets and are used to attach to the battery electrode ends. Limiting holes are arranged on the conductive plate, elastic supporting columns allowing the electrical contacts to be pressed and attached to the battery electrode ends are inserted into the limiting holes, and the elastic supporting columns are located between the opposite two electrical contacts.

Description

technical field [0001] The invention relates to the field of new energy battery packs, in particular to a new energy button battery pack. Background technique [0002] A large number of new energy batteries need to be installed on electric vehicles, and new energy batteries are installed in the form of battery packs. Sometimes it is necessary to connect multiple battery packs in series, that is, several batteries in the same battery pack need to be electrically connected, and two adjacent battery packs also need to be electrically connected, so a connecting plate is required for connection. The batteries in the same battery pack are electrically connected through the connecting plate, and the batteries in two adjacent battery packs are connected in series through the connecting plate. [0003] The connection plate of the traditional new energy battery is connected to the battery electrode by welding. The connection plate has several conductive sheets and several welding she...
