At present, power lead-acid batteries all adopt the internal formation charging process. A large amount of heat will be generated during the battery internal formation process, which will rapidly increase the internal temperature of the battery, causing irreversible damage to the internal plates of the battery, affecting the performance of the battery.

Therefore, the above terms should not be understood as limiting the present invention.
[0025] Please see Figure 1 to Figure 4As shown, an embodiment of the present disclosure discloses a formation device, including a formation tank 1 and a tank cover 2, a battery 9 is placed in the formation tank 1, and the tank cover 2 is covered on the formation tank 1. In order to ensure the consistency of the temperature of the battery 9 during the formation process, the tank cover 2 is always covered on the formation tank 1 during the formation process, and the formation tank 1 is almost in a closed state. The formation tank 1 is connected to a first cooling mechanism for cooling the battery 9 in the formation tank 1, and the first cooling mechanism includes a first storage tank 3, a first discharge pipe 4 and a first feed pipe 5. The first storage tank 3 is used to hold a phase change constant temperature material. The formation tank 1 is provided with a first through hole 10 and a second through hole. The first through hole 10 is arranged at the bottom of the formation tank 1, and the second through hole is arranged on the side wall of the formation tank 1. One end of the first discharge pipe 4 is connected to the first through hole 10, and the other end of the first discharge pipe 4 is connected to the first storage tank 3. One end of the first feed pipe 5 is connected to the second through hole, and one end of the first discharge pipe 4 is connected to the first storage tank 3. A storage tank 3 is connected, the first feed pipe 5 is also connected with a pump body 6, the pump body 6 is used to transport the phase change constant temperature material in the first storage tank 3 to the formation tank 1, the phase change constant temperature material cools down the battery 9 in the formation tank 1, the formation tank 1, the first unloading pipe 4, the first storage tank 3 and the first feed pipe 5 form a cycle, so that the phase change constant temperature material can be recycled, avoiding the waste of the phase change constant temperature material, the formation tank 1 is also connected with a second cooling mechanism, the second cooling mechanism is used to cool down the phase change constant temperature material in the formation tank 1 while also cooling the battery 9, further avoiding the increase of the temperature of the battery 9 in the formation tank 1. Due to the second cooling mechanism, the consistency of the temperature of the battery 9 in the formation tank 1 is guaranteed, thereby ensuring the uniformity of the formation of the battery 9.
[0026] Furthermore, the first storage tank 3 is connected to a heat exchange component, which is used to make the temperature in the first storage tank 3 greater than the phase change temperature of the phase change isothermal material, so that the phase change isothermal material is in a liquid state in the first storage tank 3, so that the pump body 6 can pump the phase change isothermal material into the synthesis tank 1. Specifically, the heat exchange component is a heat exchanger.
[0027] It should be noted that the phase-change constant temperature material in the present disclosure is in direct contact with the battery 9 after entering the formation tank 1. The phase-change constant temperature material in the present disclosure can be acetic acid or water. If the phase-change constant temperature material is acetic acid, since the melting point of acetic acid is 16°C, the heat exchange component needs to ensure that the temperature in the first storage tank 3 is greater than 16°C to prevent acetic acid from becoming solid due to too low temperature, resulting in the pump body 6 being unable to pump it into the formation tank 1; if the phase-change constant temperature material is water, since the melting point of water is 0°C, the heat exchange component needs to ensure that the temperature in the first storage tank 3 is greater than 0°C to prevent water from becoming solid due to too low temperature, resulting in the pump body 6 being unable to pump it into the formation tank 1. Preferably, the phase-change thermostatic material is an inorganic phase-change material of calcium chloride hexahydrate and water, and the additives are sodium chloride and propylene glycol. It has a large thermostatic ability. When the external ambient temperature is lower than 34°C, the material is solid. When the external ambient temperature is higher than 34°C, the material begins to absorb heat and melt into liquid, taking away a large amount of heat. In this process, a relatively long temperature platform is maintained, which can bring about a constant temperature effect, thereby reducing energy consumption while ensuring the uniformity of the formation. It can be understood that the phase-change thermostatic material in the present disclosure can also be other materials or components, as long as it does not react with the surface of the battery 9, does not cause corrosion on the surface of the battery 9, and has the effect of cooling the battery 9.
[0028] In order to ensure that the battery 9 in the formation tank 1 is completely immersed in the phase-change constant temperature material, a liquid level sensor is provided in the formation tank 1, and the liquid level sensor is connected to a controller, and the controller is controlled and connected to the pump body 6. When the height of the phase-change constant temperature material in the formation tank 1 is lower than the preset height, the controller controls the pump body 6 to draw the phase-change constant temperature material in the first storage tank 3 into the formation tank 1. Specifically, the preset height cannot be lower than the height of the battery 9, and it is appropriate to be slightly higher than the height of the battery 9.
[0029] Please see Figure 1 to Figure 3As shown, in one embodiment of the present disclosure, the side wall of the formation tank 1 is provided with a third through hole, the second cooling mechanism includes a second storage tank 7 and a second feed pipe 8, a cooling material is provided in the second storage tank 7, one end of the second feed pipe 8 is connected to the second storage tank 7, and the other end of the second feed pipe 8 is connected to the third through hole, and the cooling material enters the formation tank 1 from the second feed pipe 8. Specifically, the cooling material is liquid nitrogen, and after the cooling material enters the formation tank 1, it will spread out and directly contact the phase change constant temperature material. Since the battery 9 is immersed in the phase change constant temperature material, the battery 9 generally does not directly contact the liquid nitrogen. The side wall of the formation tank 1 includes a first side wall and a second side wall, the first side wall is directly opposite to the second side wall, and the first side wall and the second side wall are both provided with a third through hole, and the height of the two third through holes is flush, and the second feed pipe 8 includes a first tube body and a second tube body, and the first tube body and the second tube body are respectively connected to the two third through holes. Preferably, the height of the second through hole is lower than the height of the third through hole. This is because the second cooling mechanism is arranged above the formation tank 1 and the first cooling mechanism is arranged below the formation tank 1, so as to avoid the phase change constant temperature material from contaminating the third through hole when entering the formation tank 1 through the second through hole, thereby causing contamination of the second feed pipe 8 and even the second storage tank 7.
[0030] In one embodiment of the present disclosure, a temperature sensor is provided in the formation tank 1, the temperature sensor is connected to a controller, the second storage tank 7 is provided with a switch valve, the switch valve is connected to the controller control, when the temperature in the formation tank 1 reaches the first preset temperature, it means that the battery 9 has risen to a certain temperature at this time, and the phase change constant temperature material can no longer effectively cool the battery 9, the temperature sensor transmits the signal to the controller, the controller controls the switch valve to open, and the cooling material enters the formation tank 1 from the second feed pipe 8 to cool the phase change constant temperature material; after the first cooling mechanism and the second cooling mechanism cool down, when the temperature in the formation tank 1 drops to the second preset temperature, the temperature sensor transmits the signal to the controller, and the controller controls the switch valve to close. Specifically, the first preset temperature is 35°C, and the second preset temperature is 30°C.
[0031] Further, the temperature sensor senses different temperatures in the formation tank 1 and transmits the signal to the controller, which controls the switch valve to open different degrees. When the temperature in the formation tank 1 reaches 35°C, the switch valve is opened by 5 degrees. For every 1°C increase in the temperature in the formation tank 1, the switch valve is opened by 5 degrees until the switch valve is fully opened. When the temperature in the formation tank 1 drops to 30°C, the switch valve is closed once.
[0032] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
