Description

Technical Field

[0001] The utility model relates to the technical field of automobile starting batteries, in particular to a modular ion battery for automobile starting. Background Art

[0002] With the improvement of people's living standards, the number of cars owned is also increasing. At present, most cars are fuel-powered. When the vehicle is ignited, the vehicle's starting battery needs to provide electricity to realize engine ignition. At present, the starting battery of the vehicle is mostly lead-acid batteries. Lead-acid batteries are generally deep charged and discharged within 400 times, have memory, and have a lifespan of about two years, which is a short service life. With the use of lead-acid batteries, the storage capacity of lead-acid batteries gradually decreases or even loses its storage capacity, resulting in the inability to start the vehicle, which brings great trouble to the owner. In addition, during the charging process of the car starting battery, due to the excessive charging current and small internal resistance, the lead-acid battery electrolyte generates high heat, and the battery box is prone to leaking electrolyte, causing heavy metal lead pollution, posing a threat to human life and health; in addition, the lead-acid battery is large in size and weight, which brings troubles to transportation and battery replacement.

[0003] There are currently two alternatives to lead-acid starting batteries on the market: one is a lithium-ion starting battery, and the other is a sodium-ion starting battery. However, as described in prior art publications such as CN107316958A, CN116759690A, CN 111048826A, and CN211789130U, all starting batteries on the market are generally independently provided with a shell, which needs to be assembled during production, resulting in high production costs. In addition, the size of the starting battery will change due to changes in the battery capacity. Generally speaking, the larger the battery capacity, the larger the volume. Therefore, in order to meet demand, starting battery manufacturers generally produce starting batteries of multiple sizes. The manufacturer's production cost is high and the applicability of this type of battery is poor. In addition, in order to meet consumer demand, 4S stores and other sellers or repairers need to stockpile a large number of batteries of various specifications, which easily leads to accumulation and further increases product costs. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a modular ion battery for starting a car, which is used to solve the problems of high cost and poor applicability in the prior art.

[0005] In order to achieve the above-mentioned purpose and other related purposes, the utility model provides a modular ion battery for automobile starting, which cooperates with a starting battery mounting frame on the automobile to form an automobile starting battery, and a receiving cavity is formed on the starting battery mounting frame. The modular ion battery at least includes:

[0006] A modular battery pack is detachably mounted in the receiving cavity, wherein the modular battery pack includes a plurality of battery bodies connected in parallel;

[0007] A limiting mechanism, which is detachably mounted on the starting battery mounting frame and cooperates with the modular battery pack in a limiting manner;

[0008] A first bus bar connected to the positive electrodes of all battery cells;

[0009] A second bus bar connected to the negative electrodes of all battery cells;

[0010] A positive electrode connector connected to the first bus bar;

[0011] The negative electrode connector is connected to the second bus bar.

[0012] Therefore, the utility model provides a modular ion battery for automobile starting with a brand-new structure. The modular ion battery for automobile starting omits the shell structure and is directly installed on the starting battery mounting frame of the automobile. It not only effectively saves costs, but also effectively reduces the assembly process in the production link. The production link only needs to produce accessories such as battery bodies and bus bars. More importantly, the utility model provides a brand-new method for forming a starting battery, that is, modular battery packs of different specifications (different battery capacities) are formed by selecting different numbers of battery bodies to combine, and can be adapted to starting battery mounting frames of different sizes. The two can be assembled and combined to obtain a set of starting batteries. The modular ion battery can cover almost all types of automobiles on the market and has strong applicability; each component is detachable in design, easy to disassemble and assemble, and the combination method can be changed according to actual needs.

[0013] In one embodiment of the present invention, the battery body is a lithium-ion battery or a sodium-ion battery, which is easier to miniaturize and modularize than a lead-acid battery, and is convenient for modular installation.

[0014] In one embodiment of the utility model, the modular ion battery for starting a vehicle further includes a first connector, a first connector is disposed on the top of the battery body, and the first connector is connected to the first bus bar through the first connector.

[0015] In one embodiment of the utility model, a first threaded hole is provided on the top of the first connector to be threadedly matched with the first connector, thereby realizing a detachable connection between the first bus and the first connector, omitting the connecting wire between the two, and simplifying the structure.

[0016] In one embodiment of the utility model, the modular ion battery for starting a vehicle further includes a second connector, a second connector is disposed on the top of the battery body, and the second connector is connected to the second bus bar through the second connector.

[0017] In one embodiment of the present invention, a second threaded hole is provided on the top of the second connector to be threadedly matched with the second connector, thereby realizing a detachable connection between the second bus and the second connector, omitting the connecting wire between the two and simplifying the structure.

[0018] In one embodiment of the utility model, the limiting mechanism includes a pressure strip, a pressing plate and a third connecting member. The pressure strip cooperates with the accommodating cavity to limit the position and is detachably installed above the modular battery pack. The pressing plate is installed on the starting battery mounting frame through the third connecting member and is used to press the pressure strip.

[0019] In one embodiment of the utility model, the starter battery mounting frame is provided with a third threaded hole that is threadably matched with the third connecting member, thereby enabling the pressure strip to be detachable, and further enabling the limiting mechanism to be detachable.

[0020] In one embodiment of the present invention, the height of the modular battery pack is less than the depth of the accommodating cavity, and the difference between the height and the depth is equal to the thickness of the pressure strip. Therefore, the pressure strip can be installed on the top of the modular battery pack and the upper end surface of the installed pressure strip is just flush with the upper end surface of the starter battery mounting frame, which is convenient for installing the pressure piece for limiting.
