Description

Technical Field

[0001] This utility model relates to the field of battery design and use, specifically to a sodium-ion engine starting battery. Background Technology

[0002] Currently, the engine starter batteries sold and used in the market are basically traditional lead-acid batteries. The disadvantages of lead-acid batteries are as follows:

[0003] 1. Lead in lead-acid batteries is a heavy metal. Improper handling during its production, use, or recycling can cause significant pollution and damage to the environment.

[0004] 2. Lead-acid batteries typically have only 300-500 charge-discharge cycles, or a lifespan of 2-3 years. This not only increases the workload of lead-acid battery recycling but also raises the cost for consumers.

[0005] 3. Because lead-acid batteries do not have a battery management system, consumers cannot keep track of their relevant information, such as charge level. This can lead to situations where the lead-acid battery is over-discharged, causing the engine to fail to start or the battery to be damaged. Utility Model Content

[0006] The technical problem this invention aims to solve is that lead-acid batteries, when used as starting batteries, suffer from short lifespan, heavy metal pollution, and lack of a management system.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model is a sodium-ion engine starting battery, including a bottom shell, an internal battery module, and a top cover. The internal battery module is snapped into the bottom shell, and the top cover is mounted on the bottom shell. The top cover has two sets of first mounting posts, and a power display board is mounted on the first mounting posts by bolts. The power display board slides through the top cover. The top cover has multiple sets of second mounting posts, and a battery management module is mounted on the second mounting posts by bolts. The battery management module and the power display board are electrically connected by a ribbon cable.

[0008] Furthermore, the battery management module is powered on and connected to a terminal body, which slides through the upper cover of the outer casing.

[0009] Furthermore, the electrode body is provided with a threaded hole, and an external electrode is installed on the electrode body by bolts.

[0010] Furthermore, the external terminal post is provided with multiple sets of mounting holes, which can realize the connection of the positive and negative terminals of the battery in three directions: vertically upward, horizontally to the right, or horizontally downward. This enables the product user to quickly complete the battery connection work in the small battery compartment space and improves the reliability of the battery connection.

[0011] Furthermore, the outer casing cover is provided with a glue-applying groove.

[0012] Furthermore, the internal battery module includes an epoxy resin board, a cell bracket, and a cell body. There are two sets of epoxy resin boards. One set of epoxy resin boards is placed inside the bottom shell of the outer casing, and the other set of epoxy resin boards is placed inside the top cover of the outer casing and covers the battery management module. There are two sets of cell brackets. The cell brackets are placed on the epoxy resin boards, and the cell body is snapped between the cell brackets and electrically connected to the battery management module.

[0013] Preferably, this design features an emergency start function, which can be activated by pressing the power button on the battery cover for 3 seconds. This function allows the user to successfully start the engine even if the battery is in an over-discharge protection state, without having to resort to jump-starting or calling roadside assistance.

[0014] The beneficial effects of this utility model by adopting the above structure are as follows:

[0015] 1. Its built-in sodium-ion battery management module has the ability to work in conjunction with the vehicle's alternator, which can effectively prevent damage to the alternator caused by the energy generated by the alternator not being released when the battery enters the charging protection state.

[0016] 2. The battery output terminal uses a detachable three-way terminal. This three-way terminal helps users achieve a quick and efficient connection between the battery and the vehicle in the best possible way, and significantly improves the reliability of the wiring harness connection.

[0017] 3. The battery management module is fixed to the top cover of the casing, separate from the cell module, which can minimize the risk of short circuits. It also allows for independent maintenance of the BMS or the cell module. Attached Figure Description
