[0042] When some battery devices of the electric device are charged, they need to be charged under a certain pressure, and a pressurizing module needs to be arranged in the battery device.

[0052] In the battery swapping station 100, when the battery device 200 enters the charging station, the battery swapping station 100 cooperates with the medium access interface 210 of the battery device 200 through the medium joint 11, so that the medium can be introduced into the inside of the battery device 200, thereby providing effective physical support for the battery monomer 100 in the inside of the battery device 200.

[0066] As shown in FIG. 1, the medium connector 11 is connected to the battery device 200, and the medium connector 11 is connected to the medium circulation module 20. Figure 1 and Figure 5 As shown, the medium connector 11 is divided into two connectors, a medium inflow connector 112 and a medium outflow connector 111, the medium outflow connector 111 is a connector for the medium to flow out of the medium circulation module 20, and the medium inflow connector 112 is a connector for the medium to flow into the medium circulation module 20; correspondingly, the medium in-out interface 210 on the battery device 200 is also divided into two, one interface is for the medium to flow into the battery device 200, and the other interface is for the medium to flow out of the battery device 200, i.e., the flow-in interface 2102 and the flow-out interface 2101, the medium outflow connector 111 is in communication with the flow-in interface 2102, and the medium inflow connector 112 is in communication with the flow-out interface 2101, thereby forming a pipeline that can circulate.
[0067] Specifically, when it is necessary to inject liquid into the battery device 200, the first control valve 25 on the first pipeline 23 is controlled to be opened, and the second control valve 26 on the second pipeline 24 is controlled to be closed, thereby ensuring that the battery device 200 is relatively sealed, the pump body 21 works, and the liquid in the storage container 22 can be pumped into the battery device 200 until the battery device 200 reaches a preset pressure value, the first control valve 25 is controlled to be closed, and the injection of the liquid into the battery device 200 is completed, at which time the battery device 200 can be charged.
[0068] After the battery device 200 is charged, it is necessary to discharge the liquid in the battery device 200, the second control valve 26 on the second pipeline 24 is controlled to be opened, and the pump body 21 works to pump the liquid medium in the battery device 200 into the storage container 22, thereby discharging the liquid medium in the battery device 200.
[0069] In the above technical solution, the liquid medium can be introduced into the battery device 200, the liquid can provide effective physical support and stable extrusion force for the battery monomer 100 inside the battery device 200, the transmission efficiency of ions can be optimized and the growth of dendrites can be inhibited, the discharge of the liquid medium can be realized, the weight increase of the battery device 200 can be avoided, and the endurance of the electric equipment can be improved.
[0070] As shown in FIG. 1, the medium connector 11 is connected to the battery device 200, and the medium connector 11 is connected to the medium circulation module 20.

[0078] like Figure 3 As shown, in some embodiments, the storage container 22 is a gas storage container, and the medium is gas.
[0079] The gas can be nitrogen or argon, etc. By using a gaseous medium, the impact on the weight of the battery device 200 during injection can be further reduced compared to using a liquid medium, while avoiding liquid leakage or corrosion problems.
[0080] like Figure 3 As shown, the storage container 22 stores gas, and a first pipeline 23 is provided between the pump body 21 and the medium connector 11. A first control valve 25 is provided on the first pipeline 23. When the first control valve 25 is opened, the medium connector 11 and the pump body 21 are connected. The pump body 21 can pump the medium into the battery device 200 and use the gas medium to pressurize the battery device 200 to apply uniform pressure inside the battery device 200, thereby facilitating the charging of the battery device 200.
[0081] After charging is complete, the medium connector 11 can be disconnected from the medium inlet / outlet interface 210 of the battery device 200, and the high-pressure gas inside the battery device 200 can be discharged through the medium inlet / outlet interface 210. Thus, the gas medium inside the battery device 200 can be discharged without the need for additional power.
[0082] In the above technical solution, by setting up a gas storage container, gas can be pumped into the battery device 200, and the gas pressurizes the inside of the battery device 200 to reach a preset pressure value, so that the battery device 200 can be charged.
[0083] In some embodiments, the medium is air.
[0084] like Figure 3 As shown, air can be stored in storage container 22, and the air in storage container 22 can be pumped out by pump body 21. Alternatively, air from the outside environment can be directly taken in, in which case it is necessary to keep the air dry. Figure 4 As shown, the pump body 21 is directly connected to the outside world. The pump body 21 can pump air into the battery device 200 to make the battery device 200 reach a preset pressure value, which facilitates the subsequent charging of the battery device 200.
[0085] In the above technical solution, by using air as a medium, the cost is further reduced. Air is easy to obtain and can be directly discharged into the external environment after use, without causing pollution and avoiding the waste of high-cost media.
[0086] As Figures 1-2 shown, in some embodiments, the medium circulation module 20 further comprises a temperature adjusting member 27 for adjusting the medium to a preset temperature, so as to introduce the medium at the preset temperature into the battery device 200.
[0087] By arranging the temperature adjusting member 27, the medium can be heated or cooled, and then the medium at an appropriate temperature is introduced into the battery device 200, so as to realize accurate regulation of the temperature of the battery device 200. In a low-temperature environment, the temperature of the battery device 200 can be raised by heating the medium, so as to improve the low-temperature performance of the battery device 200. In a high-temperature environment, the heat of the battery device 200 is removed by cooling the medium, so as to prevent the battery device 200 from overheating and causing safety risks.
[0088] In the above technical solution, the medium circulation module 20 not only provides effective physical support for the battery device 200, but also controls the thermal management of the battery device 200. Compared with the traditional air cooling or water cooling mode, the thermal management mode based on the medium has higher heat conduction efficiency and response speed, and can quickly adjust the working temperature of the battery device, thereby improving the overall system stability.
[0089] As Figure 1 shown, in some embodiments, the temperature adjusting member 27 is arranged on the storage container 22 of the medium circulation module 20.
[0090] As Figure 1 shown, the temperature adjusting member 27 is arranged outside the storage container 22, and of course can be integrated inside the storage container 22. The temperature adjusting member 27 can heat or cool the storage container 22. The temperature adjusting member 27 can include a heating member, a semiconductor refrigeration sheet, etc., so as to realize heating or cooling of the medium.
[0091] In the above technical solution, by arranging the temperature adjusting member 27 on the storage container 22, the thermal management of the battery device 200 can be controlled, and without complex pipeline arrangement, the structure is simple and convenient for disassembly and maintenance.
[0092] As Figure 2 shown, in some embodiments, the temperature adjusting member 27 is arranged on the pipeline between the pump body 21 and the medium joint 11 of the medium circulation module 20.
[0093] As Figure 2 shown, the temperature adjusting member 27 is arranged on the first pipeline 23, and the temperature adjusting member 27 is located between the pump body 21 and the medium outflow joint 111. The temperature adjusting member 27 can be a heat exchanger. By adjusting the temperature of the temperature adjusting source side of the heat exchanger, the medium can be heat-exchanged and temperature-adjusted. Thus, the temperature adjusting member 27 can heat-exchange the medium in time, and the pressure loss is small.
[0094] In the technical solution, the temperature adjusting member 27 is arranged on the pipeline between the pump body 21 and the medium joint 11, so that the battery device 200 can be controlled for thermal management, the temperature of the medium can be adjusted more timely, and the pressure loss is small.
[0095] As shown in Figure 5 and Figure 6 In some embodiments, the battery body 10 has a plurality of battery storage units 101, each of which is provided with a medium joint 11 and a charging joint 12, and the charging joint 12 is adapted to cooperate with the charging port of the battery device 200 to charge the battery device 200.

By designing the medium circulating module 20 in the battery charging and replacing station 100, the battery device 200 can be provided with effective physical support and stable extrusion force by the medium in the medium circulating module 20 when charging, so as to optimize the ion transmission efficiency and inhibit the growth of dendrites. At the same time, there is no need to design a pressurizing module in the battery device 200, which avoids the increase of the weight of the battery device 200 and the reduction of the energy density, and is beneficial to realize a battery device 200 with higher energy density, longer service life and higher safety.

[0099] The battery device 200 herein can be a solid-state battery device or a negative electrode-free battery device (not without a negative electrode, but with only a bare current collector on the negative electrode side after manufacturing is completed, without pre-coating any negative electrode active material), after the battery device 200 enters the battery swap station 100, the battery swap station 100 can pass the medium into the inside of the battery device 200 through the medium joint 11 cooperating with the medium access interface 210 of the battery device 200, can provide effective physical support for the battery monomer 100 inside the battery device 200, can provide effective physical support and stable extrusion force for the battery monomer 100 inside the battery device 200 through the medium circulating module 20, optimize the transmission efficiency of ions and inhibit the growth of dendrites; after the charging is completed, the medium in the battery device 200 can be discharged from the battery device 200 through the medium access interface 210, ensuring that the battery device does not need to carry excess medium when used on a power-using device, thereby maintaining the lightweight design and structural integrity of the battery device 200.
[0100] In the above technical solution, the weight of the battery device 200 is avoided from increasing and the energy density is avoided from decreasing, which is beneficial to realize a battery device 200 with higher energy density, longer service life and higher safety.
[0101] Through centralized management and operation in the battery swap station 100, not only the charging efficiency and safety of the battery device 200 can be significantly improved, but also the cycle life of the battery device 200 can be prolonged and the maintenance cost can be reduced. In addition, the types of medium, pressure parameters and thermal management strategies can be flexibly adjusted according to different types of battery device 200 and charging needs, so as to meet the diversified needs of battery device technology development.
