Embodiment 1

[0044] figure 1 It is a structural top view of Embodiment 1 of the cell support of the present invention; figure 2 It is a structural bottom view of Embodiment 1 of the cell holder of the present invention. Such as figure 1 and figure 2 As shown, the cell support includes: a cell accommodating portion and a frame, the cell accommodating portion is disposed inside the frame, the cell accommodating portion is provided with 45 cell holes 11, and the cell accommodating portion and the frame are integrally formed.

[0045] One side of the cell support frame is provided with a plurality of openings 4 and bosses 5, and the opposite side is also provided with a plurality of openings 4 and bosses 5, and the openings 4 and bosses 5 on both sides Position and size can be matched exactly. The opening 4 and the boss 5 can be drafted at 1°, which is convenient for installation.

[0046] This embodiment provides a cell support. The frame of the cell support is provided with mutually m...

Embodiment 2

[0057] image 3 It is a structural top view of Embodiment 1 of the cell support of the present invention; Figure 4 It is a structural bottom view of Embodiment 1 of the cell holder of the present invention. Such as image 3 and Figure 4 As shown, the difference from Embodiment 1 is that the cell holder of this embodiment has 15 cell holes 11 .

[0058] The present invention also provides an assembled battery, which includes the above-mentioned cell holder. Figure 8 It is a structural connection diagram of an embodiment of the combined battery of the present invention. Such as Figure 8 As shown, the assembled battery includes at least a plurality of battery modules and a protective cover. The battery module is connected with the protective cover

Abstract

The present invention discloses an electrical core bracket and a combined battery. The electrical core bracket comprises an electrical core accommodating part and a border, wherein the electrical core accommodating part is arranged inside the border and is provided with a plurality of electrical core holes, the first side of the border is provided with a plurality of first bosses, and the size of the first boss is matched to the size of the hole on one side of the border of another electrical core bracket. According to the present invention, the mutually matched bosses and counterbores are arranged on the border of the electrical core bracket, so a plurality of battery modules can be integrally connected in series according to different battery capacities, and a variety of batteries having different capacities can be produced by only using one electrical core bracket so as to improve the versatility and the interchangeability of the electrical core bracket.

Description

technical field [0001] The invention relates to the field of power batteries, in particular to a cell support and a combined battery. Background technique [0002] Reducing energy consumption, energy saving and environmental protection are the themes of social development today. Therefore, as a major contributor to oil consumption and carbon dioxide emissions, automobiles must undergo revolutionary changes and develop new energy vehicles. Under this background, the further development of pure electric vehicle and hybrid vehicle technology has solved some energy problems, but there are also many disadvantages, such as lagging battery technology, short cruising range, long research and development cycle, and research and development costs. The development and popularization of new energy vehicles are restricted by the high cost of production and production. The power battery is one of the cores of electric vehicles. From the power battery to the power battery pack and its sy...
