Description

Technical Field

[0001] The present invention relates to the technical field of vehicle batteries, and in particular to an intelligent control cover plate of a battery. Background Art

[0002] Batteries are an essential part of a car and can be divided into traditional lead-acid batteries and maintenance-free batteries.

[0003] Since the battery uses lead-calcium alloy as the grid, the amount of water decomposition and water evaporation generated during charging is small, and the outer shell adopts a sealed structure, so the sulfuric acid gas released is also very small. Therefore, compared with traditional batteries, it does not require the addition of any liquid, docking terminal heads, and has a long power storage time.

[0004] Traditional single lead-acid batteries, valve-regulated batteries, motorcycle batteries, or lithium-powered batteries for new energy vehicles, etc., are all bare positive and negative, that is, the positive and negative electrodes are not only exposed on the outside of the battery body, but also connected to the inside and charged. This poses a risk during the assembly and transportation of the battery. Once a conductor connects the two electrodes, a short circuit will occur, resulting in an electric fire. The newly invented intelligent control battery, although it also has positive and negative electrodes on the outside, the positive electrode does not output voltage and current to the outside when there is no input signal, which greatly reduces the risk. Safety risks are further controlled. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0023] See also Figure 1-4 The present invention provides the following technical solutions: a smart control cover plate for a battery, comprising a top cover sheet 1 and a battery body 13, wherein a battery cell 14 is fixedly installed inside the battery body 13, an inner insulating isolation plastic part 12 is arranged at the bottom of the top cover sheet 1, and the inner insulating isolation plastic part 12 is fixedly connected to the battery body 13, a positive electrode collector block 6 is fixedly installed on the left side of the top of the battery body 13, a positive electrode switch control module 7 is fixedly installed on the top of the positive electrode collector block 6, a positive electrode conductive output block 5 is fixedly installed on the top of the positive electrode switch control module 7, and a trigger interface 16 is arranged inside the positive electrode conductive output block 5, a negative electrode collector block 3 is fixedly installed on the right side of the top of the battery body 13, a negative electrode temperature control semiconductor 4 is fixedly installed on the top of the negative electrode collector block 3, a negative electrode conductive output block 2 is fixedly installed on the top of the negative electrode temperature control semiconductor 4, an injection molding packaging plastic part 11 is fixedly installed on the top of the top cover sheet 1, and the trigger interface 16 is electrically connected to a single cell control switch 17.

[0024] In this embodiment, a switch-controlled positive electrode module is composed of the positive electrode conductive output block 5, the positive electrode collector block 6, the positive electrode switch control module 7 and the trigger interface 16. The internal control method of the module may be a mechanical relay, a solid-state normally open relay, or a semiconductor integrated circuit. A temperature-controlled semiconductor negative electrode module is composed of the negative electrode conductive output block 2, the negative electrode collector block 3 and the negative electrode temperature control semiconductor 4. The internal control method of the module may be a mechanical temperature-sensitive spring sheet, a solid-state normally closed relay, or a semiconductor integrated circuit; thereby, the temperature can be controlled, the risk of continuous high temperature generated during the use of the battery is reduced, and the battery is guaranteed to work reliably under temperature control conditions. Reducing the risk can extend the service life of the battery; the trigger interface 16 and the single cell control switch 17 can control the electric energy, reduce the risk of fire caused by electric fire due to other reasons during the use of the battery, improve the safety and reliability of the battery, and ensure the safety of people's lives and property.

[0025] Specifically, the top of the top cover plate 1 is fixedly connected with an explosion-proof plate 8 , and the upper surface of the explosion-proof plate 8 is fixedly connected with an explosion-proof protective film 9 .

[0026] In this embodiment, if the pressure in the internal space of the battery body 13 exceeds the designed value, the explosion-proof plate 8 will rupture, discharge the internal gas of the battery body 13, and reduce the pressure of the battery body 13, thereby preventing the entire battery from exploding and reducing the damage caused by the explosion.

[0027] Specifically, a passage opening 15 is provided on the left side of the explosion-proof disc 8 .

[0028] In this embodiment, the channel opening 15 is a passage for liquid injection and air extraction during the production process of the battery, and is also a passage for subsequent reuse or maintenance.

[0029] Specifically, the single cell control switch 17 is centrally managed by the BMS.

[0030] In this embodiment, when the BMS stops working or any circuit from the single cell control switch 17 to the trigger interface 16 is interrupted externally, the positive switch control module 7 will be disconnected to stop the battery from supplying power to the outside.

[0031] Specifically, sealing rings 10 are provided between the negative electrode temperature control semiconductor 4 and the positive electrode switch control module 7 and the top cover sheet 1 .

[0032] In this embodiment, the sealing ring 10 can prevent gaps from being generated between the negative electrode temperature control semiconductor 4 and the positive electrode switch control module 7 and the top cover sheet 1, thereby avoiding leakage inside the battery body 13.

[0033] Specifically, the injection-molded packaging plastic part 11 covers the negative conductive output block 2 and the positive conductive output block 5 respectively.

[0034] In this embodiment, the injection-molded packaging plastic part 11 covers the negative conductive output block 2 and the positive conductive output block 5, so as to prevent leakage and make the use safer.

[0035] The working principle and use process of the present invention are as follows: the positive electrode conductive output block 5 passes through the positive electrode collector block 6, and then passes through the positive electrode switch control module 7, and the trigger signal composed of the trigger interface 16 and the single cell control switch 17 is connected to control the output of the battery energy. The negative electrode conductive output block 2 passes through the negative electrode collector block 3, and then passes through the negative electrode temperature control semiconductor 4, which is also a circuit for controlling the battery energy output. When the battery cell 14 in the battery fails for some reason, or during the power-on process, when the temperature of the entire battery reaches the set value upper line, the negative electrode temperature control semiconductor 4 will automatically disconnect the circuit, and the battery will stop supplying power to the outside. When the temperature drops to the set value lower line, the negative electrode external circuit is restored to conduction. When there is no trigger interface 16 and single cell control switch When 17 conducts the trigger signal, the positive switch control module 7 is not closed and no power is supplied to the outside, that is, the positive conductive output block 5 has no electricity. The single cell control switch 17 will be centrally managed through the BMS. When the BMS stops working or any single cell control switch 17 to the trigger interface 16 is interrupted externally, the positive switch control module 7 will be disconnected and the battery will stop supplying power to the outside. If the internal space pressure of the battery body 13 exceeds the design value, the explosion-proof plate 8 will rupture, and the internal gas of the battery body 13 will be discharged, and the pressure of the battery body 13 will be reduced; prevent the entire battery from exploding and reduce the damage caused by the explosion. The channel opening 15 is the opening for liquid injection and air extraction during the production process of the battery, and is also a channel for subsequent reuse or maintenance.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
