Description

Technical Field

[0001] This utility model relates to the field of battery module technology, and in particular to a novel module structure for low-speed vehicles. Background Technology

[0002] Industrial low-speed tricycles and four-wheeled vehicles mostly use lithium batteries as their power source. The performance, safety, and layout of their battery systems directly affect the vehicle's range and stability.

[0003] Low-speed vehicles typically feature a low chassis height and limited interior space, especially with the battery compartment positioned low and constrained by height. Therefore, the battery pack often needs to achieve the highest possible energy density and a reasonable thermal management structure within a limited height to meet the vehicle's low and compact structural layout requirements.

[0004] Existing lithium battery module structures are mostly derived from the design of medium- and high-speed electric vehicle platforms. Their module designs typically arrange the cells vertically with the terminals facing upwards, and then encapsulate multiple cells side by side into a module inside a metal casing. While this structure facilitates electrical connection and heat dissipation, it results in a relatively large overall height and a relatively small lateral width for the module.

[0005] When such module structures are directly used in low-speed three- and four-wheeled vehicles, at least the following problems exist: due to the vertical arrangement of the battery cells, the module as a whole has a "tall and narrow" vertical structure, which cannot be effectively arranged inside the battery compartment of low-speed vehicles, affecting the overall vehicle wiring and center of gravity design. Utility Model Content

[0006] The purpose of this utility model is to solve the problems pointed out in the background art and to propose a new module structure for low-speed vehicles.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A novel module structure for low-speed vehicles includes a housing, a cover on top of the housing, and a battery module inside the housing. The battery module includes two module units, which are arranged adjacent to each other at the ends away from the terminals. The housing has a first sidewall and a second sidewall arranged opposite to each other. The terminal of one module unit points to the first sidewall, and the terminal of the other module unit points to the second sidewall.

[0009] Each module unit includes several battery cell units, and the multiple battery cell units are connected in series or in parallel through electrode plates. The housing is provided with electrode plate supports and protective plates respectively close to the first side wall and the second side wall.

[0010] The electrode holder has a through hole through which the electrode post of the power cell unit passes. The electrode is located on the side of the electrode holder away from the power cell unit, and the electrode is welded and fixed to the electrode post of the corresponding power cell unit.

[0011] The module structure includes an upper cover plate and a lower cover plate, and the battery module is sandwiched between the upper cover plate and the lower cover plate. The sides of the upper cover plate and the lower cover plate are fixedly assembled by several sheet metal parts.

[0012] The housing is equipped with an electrical protection board, which is electrically connected to the battery module. The housing has a third side wall located between the first and second side walls, and the electrical protection board is located between the third side wall and the battery module.

[0013] The end of the module unit furthest from the pole post is defined as the bottom end, and an electric heating plate is sandwiched between the bottom ends of the two module units.

[0014] The box lid has perforations on both sides, through which a hanging rope is threaded.

[0015] The novel module structure for low-speed vehicles proposed in this utility model has the following advantages: the module units of this device are laid flat, that is, the poles are set on the side and the module units are arranged end to end, which reduces the overall height of the module and allows the housing to be arranged within the limited height space of the low-speed vehicle chassis, achieving a flat arrangement and meeting the installation requirements of low-profile vehicles.

[0024] The module unit 10 of this device is laid flat, that is, the pole is set on the side and the module unit 10 is arranged end to end, which reduces the overall height of the module. The housing 1 can be arranged in the limited height space of the low-speed vehicle chassis, realizing a flat arrangement and meeting the installation requirements of low-profile vehicles.

[0025] refer to Figure 5 Each module unit 10 includes several cell units 12. Multiple cell units 12 are connected in series or in parallel through electrode plates 14. The housing 1 is provided with electrode plate supports 9 and protective plates 8 respectively close to the first side wall 5 and the second side wall 6. Placing the protective plate 8 on the side wall of the housing 1 and the electrode plate supports 9 can protect the electrode plate supports 9 and the electrode plates.

[0026] The electrode holder 9 has a through hole 19 through which the electrode post of the power cell unit 12 passes. The electrode 14 is located on the side of the electrode holder 9 away from the power cell unit 12, and the electrode 14 is welded and fixed to the electrode post of the corresponding power cell unit 12. The electrode holder 9 can both position the electrode and protect the power cell unit 12. After welding, multiple power cell units 12 are connected into a whole structure.

The housing 1 has a third side wall 7 located between the first side wall 5 and the second side wall 6. The electrical protection board 11 is located between the third side wall 7 and the battery module. The electrical protection board 11 in this device is also installed on the side to save top space and meet the requirements of flattening.

[0030] The end of the module unit 10 furthest from the terminal post is defined as the bottom end. An electric heating plate 13 is sandwiched between the bottom ends of the two module units 10. The electric heating plate 13 is electrically connected to the battery management system through wires and preheats the module units 10 on both sides through the electric heating plate 13.
