Embodiment 1

[0028] Embodiment 1: refer to Figure 1-12 . The lithium battery universal module with multi-functional replaceable battery cores includes battery core groups connected in series or parallel and a housing that can accommodate the battery core groups. The housing is composed of a box cover 5 and a box body 1. The box cover 5 is located in the box The upper end of the body 1 and the upper end of the box cover 5 are respectively provided with positive and negative output terminals 3 and 4, and the installation space between the box body 1 and the box cover 5 is provided with a frame 2 for placing the battery core 6, the box body 1 or the frame 2 They are all made of metal materials with better heat conduction. There are several placement frames 2-1 evenly arranged in the frame 2, and each battery cell 6 is respectively placed in the placement frame 2-1, and each battery cell 6 is connected in series or in parallel to form a battery The positive and negative poles of the core pac...

Embodiment 2

[0029] Embodiment 2: refer to Figure 8 Or 9 or 10 or 11. The frame 2 is composed of a "ten" heat dissipation frame 2a or a plurality of "ten" shape heat dissipation frames 2a superimposed on each other and arranged horizontally. placed in a frame 2-1, or between two adjacent "cross" shaped cooling frames 2a and in the frame 2-1 formed with the inner wall of the box body 1 after stacking and horizontally arranging several "ten" shaped cooling frames 2a.

Embodiment 3

[0030] Embodiment 3: refer to Figure 10 or 11. At least two groups of "ten"-shaped heat dissipation frames 2a are superimposed on each other to form a heat dissipation frame group 2a1. The frame 2 is composed of a number of heat dissipation frame groups 2a1 arranged horizontally. 1 and the adjacent two groups of heat dissipation frame groups 2a1 are placed in the frame 2-1, considering that the battery core 6 with a square or circular cross section is in use, the self-charging and discharging activity of the battery core 6 will cause the volume of the battery core to increase. There is a certain expansion, so there is an expansion gap e between two adjacent sets of cooling frame groups 2a1,

Abstract

The invention relates to a lithium battery universal module with a replaceable battery core, which comprises a battery core group which is series or in parallel connection with each other and a shell which can hold the battery core group. The shell consists of a box cover and a box body, wherein the cover is located at the upper end of the box body, and an anode output terminal and a cathode output terminal are respectively arranged on the upper end of the box cover. A frame which is used for placing the battery core is arranged in an installation space between the box cover and the box body, wherein a plurality of placing frames are evenly distributed in the frame, and the battery cores are respectively located in the placing frames. The battery cores are in series or in parallel connection with each other to form the battery core group. The anode and the cathode of the battery core group are respectively connected with anode and cathode output terminals on the box cover. The invention has the advantages that the structure is simple, and the manufacturing is convenient; each battery core in the module can be changed at will so that the matching requirement of battery core with different structures and different shapes is satisfied, in addition, a water cooling channel is arranged in the frame so that effective and balance heat dissipation can be ensured for the battery core.

Description

technical field [0001] The invention relates to a battery module, in particular to a lithium battery universal module with multifunctional replaceable battery cores. Background technique [0002] In the prior art, a battery module is composed of a plurality of battery cells. The battery cells in the battery packs or battery modules currently used in the market cannot be replaced arbitrarily. The fundamental reason is the complexity of the battery system. , basically or most of the battery modules will be sealed with the circuit system as a whole, and once the battery module is disassembled, it will be scrapped. Patent application number 200510127786.4, titled "universal battery module and control module used in conjunction with it", a high-power retractable battery box, composed of multiple general battery modules and a main control module. A high-performance and long-life power battery box can be assembled by selecting general-purpose battery modules with an appropriate na...
