[0026] In order to facilitate understanding of the utility model, the utility model will be described more comprehensively below with reference to relevant drawings.
[0027] The utility model provides a radial high-efficiency heated battery module, please refer to Figure 1 Including: battery body and the heating assembly 200 that heats battery body, battery body includes support 100 and at least one monomer battery 110, and support 100 is provided with the fixed groove 101 matched with the number of monomer battery 110, and a monomer battery 110 is arranged in a fixed groove 101, and the positive terminal of each monomer battery 110 is arranged at the same end, and all are arranged at the side of first support 102. The positive terminal of each monomer battery 110 is electrically connected, so that monomer battery 110 is connected in series, forms high voltage or large current, to adapt to more working environment.
[0028] Wherein, heating assembly 200 includes at least one heating film 201 and heating cable, and a heating film 201 is electrically connected with a heating cable. The support 100 is provided with a wire hole in each fixed groove 101, and the heating cable is drawn out from the wire hole, and then each heating cable is connected in series / parallel. The role of the heating cable is to connect the external power supply to the heating film 201 to supply power, and the current works in the heating film 201 to heat, and the heating film 201 with high temperature transfers heat to the monomer battery 110 with low temperature, and then the heating film 201 heats the monomer battery 110. Specifically, a heating film 201 is arranged on the outer side of a monomer battery 110, so that the radial effective heating area of the monomer battery 110 reaches the maximum, the power density of the heating film 201 can be effectively reduced, the reliability and heating efficiency of the battery module are enhanced, and then the heating film 201 can also be rapidly heated at a relatively small heating power density, realizing high safety.
[0029] Please refer to Figure 1The heating assembly 200 further comprises at least one sleeve 202, which is hollow inside and open at the top and bottom. The sleeve 202 is sleeved on the outside of a heating film 201, that is, the hollow part of a sleeve 202 is used to accommodate a single battery 110 and a heating film 201, and the heating film 201 is wrapped to be sleeved on the outside of the single battery 110, so as to avoid loosening of the heating film 201, and the heating film 201 is more closely attached to the single battery 110, the heating efficiency is higher, and the volume assembly rate of the battery module is improved.
[0030] Preferably, the sleeve 202 is a heat-shrinkable sleeve. In this application, the heating film 201 is attached to the outer side of the single battery 110, and a layer of heat-shrinkable sleeve is sleeved on the outside of the heating film 201. After heating, the heat-shrinkable sleeve makes the heating film 201 closely contact the outer side of the single battery 110, ensures the heat conductivity of the heating film 201 to the single battery 110, makes the heating contact surface of the single battery 110 fully utilized, and has small density, small total volume of the module, strong wrapping ability and low cost.

The size of the heat-shrinkable sleeve should be slightly larger than that of the single battery 110 and the heating film 201, so as to be able to tightly wrap the heating film 201 and shrink. Avoid selecting a heat-shrinkable sleeve with too large size, so as to avoid long heating time or tight shrinkage.
[0034] 2. Cutting and sleeving: after simple fixing by using tools, heating and shrinking can be performed.
[0035] 3. Heating and shrinking: a special hot air gun or heating tool is used to uniformly heat one end of the heat-shrinkable sleeve. During heating, the air in the heat-shrinkable sleeve should be uniformly heated from one end to the other end or from the middle to both sides, so as to ensure that the air in the heat-shrinkable sleeve is discharged and the bulging phenomenon is avoided, so as to achieve the best heat-shrinking effect.
[0036] 4. Fixing completion: during the heating process, the heat-shrinkable sleeve will gradually shrink and tightly wrap the cable. After shrinking to the appropriate position, the hand or tool can be used for further fixing to ensure that it is tightly attached.
