Description

Technical Field

[0001] This utility model relates to the field of new energy vehicle technology, and in particular to a new energy vehicle battery. Background Technology

[0002] With technological advancements, new energy vehicles are increasingly being used in the transportation sector, leading to a rise in the production of electric vehicles and new energy batteries. New energy sources are cleaner and more renewable compared to traditional fuel energy, having a relatively smaller impact on the environment and producing less pollution during use, making them the preferred mode of transportation under the call for energy conservation and emission reduction.

[0003] New energy vehicle batteries are used to start the vehicle and supply power to all electrical devices in the vehicle when the engine is off. For example, they power low-voltage electrical appliances such as headlights, windshield wipers, door locks, or the central control screen, serving as a low-voltage auxiliary battery. Therefore, the quality of new energy vehicle batteries is crucial to the driving experience of new energy vehicles.

[0004] Currently, most new energy batteries use lead-acid batteries. Lead-acid batteries are widely used because of their readily available raw materials, reliable performance, easy recycling, and suitability for high-current discharge.

[0005] Currently, mainstream new energy vehicles (including pure electric and plug-in hybrid) have widely adopted lithium-ion batteries, such as lithium iron phosphate or ternary lithium batteries, in their low-voltage auxiliary power systems.

[0006] However, existing lithium iron phosphate or ternary lithium batteries provide high-voltage power for new energy vehicles, but lack a compact power supply for low-voltage electrical equipment, such as navigation devices. Furthermore, as new energy vehicles become more intelligent and have more and more functional modules, the space left for battery installation in the vehicle is also decreasing. Summary of the Invention

[0007] The purpose of this utility model is to provide a new energy vehicle battery that solves the problems of large size and flimsy structure.

[0008] To achieve this objective, the present invention adopts the following technical solution: This utility model relates to a new energy vehicle battery, including a battery casing, a battery inner tray, and a battery cover. A lithium iron phosphate battery cell is installed in the battery inner tray. The battery inner tray is assembled within the battery casing and forms an installation space with the battery casing. A main control circuit board is laterally fixedly installed in the battery inner tray within the installation space. The battery cover is recessed to form a first terminal slot, a second terminal slot, and a handle slot. A positive terminal is provided in the first terminal slot, and a negative terminal is provided in the second terminal slot. The battery cover is rotated and folded in the handle slot to install a handle. The positive and negative terminals are electrically connected to the main control circuit board, and the main control circuit board is electrically connected to the lithium iron phosphate battery cell.

[0009] In the circuit board fixing structure, the battery inner tray includes multiple fixing posts set on the side wall. The main control circuit board has multiple mounting holes, and multiple screws pass through the corresponding mounting holes and lock with the corresponding fixing posts, thereby fixing the main control circuit board on the side wall of the battery inner tray and in the mounting space.

[0010] The main control circuit board is electrically connected to the positive and negative terminals of the lithium iron phosphate battery cell. The main control circuit board is electrically connected to the positive terminal via a first wire, and the main control circuit board is electrically connected to the negative terminal via a second wire.

[0011] To further optimize space utilization, a second circuit board is installed below the battery cover. The second circuit board includes a switch controller and several battery capacity indicator lights. The second circuit board is electrically connected to the main control circuit board.

[0012] The battery cover has a switch button corresponding to the switch controller, and several indicator light windows are opened corresponding to the battery capacity indicator lights.

[0013] To make the assembly more secure, a positioning groove is provided on the top of the battery casing, and positioning protrusions are provided around the bottom of the battery cover. A sealing ring is placed in the positioning groove.

[0014] In practice, the battery casing is provided with several locking holes, the bottom of the battery cover is provided with several buckles and several limiting posts. The positioning protrusion of the battery cover is first inserted into the positioning groove. The buckle cooperates with the corresponding locking hole to seal and fix the battery cover on the battery casing. The limiting post limits the inner support of the battery and the lithium iron phosphate cell.

[0015] Preferably, the battery cover has recesses at two corners to form the first terminal slot and the second terminal slot, so that the positive terminal and the negative terminal have more wiring positions. The handle slot has the same shape as the handle, and the height of the handle slot is the same as the width of the handle.

[0016] The battery cover has at least one first cable tray on the wall of the first terminal slot and at least one second cable tray on the wall of the second terminal slot.

[0017] Furthermore, the outer wall of the battery casing is provided with a first positioning protrusion and a second positioning protrusion for pre-positioning.

[0018] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a new energy vehicle battery with separate main control circuit board and second circuit board. An installation space is formed between the battery inner tray and the battery outer casing, and the main control circuit board is laterally fixed in this space, resulting in a reasonable layout of the circuit board and battery structure. Furthermore, the handle can be folded flat onto the battery cover. Overall, this design makes the battery structure more compact, smaller in size, and easier to install in new energy vehicles.

[0019] The present invention relates to a new energy vehicle battery that uses a battery tray to install lithium iron phosphate cells in order to improve the working voltage, energy density and cycle life of the new energy vehicle battery.

[0020] The new energy vehicle battery of this utility model has a switch controller and several battery capacity indicator lights set under the battery cover, which makes it convenient to operate and allows for more intuitive observation of the power level. Attached Figure Description

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figure 1 , Figure 2 as well as Figure 3 The new energy vehicle battery of this utility model embodiment includes a battery shell 10, a battery inner tray 12, a lithium iron phosphate battery cell 50, and a battery cover 20.

[0029] The battery inner tray 12 houses a lithium iron phosphate cell 20, and the battery inner tray 12 is assembled within the battery casing 10.

The main control circuit board 40 has multiple mounting holes, such as mounting holes 401, and multiple screws pass through the corresponding mounting holes and lock with the corresponding fixing posts. For example, screws pass through mounting holes 401 and lock with the first fixing post 125, thereby fixing the main control circuit 40 on the side wall 123 of the battery inner tray 12 and located in the mounting space D.

[0034] Please refer to this as well. Figure 4In this embodiment, the new energy vehicle battery includes a separate main control circuit board 40 and a second circuit board 42. An installation space D is formed between the battery inner holder 12 and the battery outer casing 10, and the main control circuit board 40 is laterally fixed within this space D. The second circuit board 42 is recessed and installed at the bottom of the battery cover 30, thus optimizing space utilization. Specifically, the second circuit board 42 is installed below the battery cover 20. The second circuit board 42 includes a switch controller 421 and several battery capacity indicator lights, such as battery capacity indicator lights 422.

Each buckle cooperates with the corresponding buckle hole to seal and fix the battery cover 20 on the battery shell 10. At the same time, all the limiting posts limit the battery inner support 12 and the lithium iron phosphate cell 50.

[0038] In this embodiment, the battery cover 20 has recesses at the left and right corners to form the first terminal slot A and the second terminal slot B, so that the positive terminal 45 and the negative terminal 46 have more wiring positions.
