[0045] In recent years, outdoor mobile power supply equipment has developed rapidly, and large capacity and high power output of the equipment have become the main competitive force. However, in the low temperature process, the low temperature will limit the input and output power of the battery, and at the same time, due to the influence of low temperature, the actual use capacity of the battery is greatly reduced, which greatly affects the user experience. Therefore, in the low temperature environment, in order to ensure the normal output of the outdoor power supply, the battery pack needs to be heated. The existing technical solution is to install an electric heating wire on the surface of the battery, and the electric heating wire is powered and heated by the battery to improve the temperature of the battery. However, the problem of this method is that the electric heating wire is usually attached to the surface of the battery, which also limits the heating process to square batteries. For cylindrical batteries, this solution is not applicable. And this way relies on battery power, when the temperature is lower than the battery discharge temperature threshold, the device will not be able to start the heating function. In addition, this heating method consumes battery capacity to heat the battery, which will greatly consume the battery capacity.

[0046] To solve the above problems, the present application provides an outdoor mobile power supply battery temperature control system, the temperature control system comprising:

[0047] A housing for accommodating a battery pack, the housing is provided with a heat transfer path, and the battery pack is arranged on the heat transfer path;

[0048] A heat generating module arranged in the housing;

[0049] A heat transfer module for transferring heat generated by the heat generating module on the heat transfer path to change the temperature of the battery pack.

[0050] The present application does not need additional heating device, but can use the waste heat generated by the outdoor mobile power supply in the working process to heat the battery, and improve the energy utilization rate of the equipment.

[0051] In an embodiment of the present application, the heat generation module includes at least one of an inverter, an AC heater, and a DC heater. The inverter generates corresponding heat during operation, and the heat generated by the inverter is sent to the inside of the battery pack to change the temperature of the battery pack by heating with the inverter, thereby achieving control of the temperature of the battery pack. The AC heater generates heat using external AC power supply, and when the battery needs to be heated, the AC heater is connected to the external power supply to generate heat, and the heat generated by the AC heater is sent to the inside of the battery pack to change the temperature of the battery pack by heating with the AC heater, thereby achieving control of the temperature of the battery pack. The DC heater generates heat using the battery pack power supply, and when the battery needs to be heated, the DC heater is powered by the battery pack to generate heat, and the heat generated by the DC heater is sent to the inside of the battery pack to change the temperature of the battery pack by heating with the DC heater, thereby achieving control of the temperature of the battery pack.

[0052] It should be noted that a person skilled in the art can set a corresponding heating mode according to different battery parameter conditions to heat the battery pack. For example, one or more of the inverter, AC heater, and DC heater is selected as the heat generation module to heat the battery pack. The battery parameter conditions include the temperature of the battery pack, the SOC of the battery pack, etc.

[0053] Please refer to Figure 1 , Figure 1 is a schematic view of an outdoor mobile power supply battery temperature control system according to an embodiment of the present application. As shown in Figure 1 , the housing is provided with a first opening and a second opening, the heat transfer path includes a first path and a second path, the heat generation module 110 is arranged on the first path, and the battery pack 140 is arranged on the second path.

[0054] The heat transfer module includes:

[0055] The first fan 120 is arranged at the first opening and located at the starting point of the first path, and is used to transfer the heat generated by the heat generation module on the first path.

[0056] The second fan 130 is arranged at the second opening and located at the end point of the second path, and is used to change the transmission direction of the heat transferred on the first path, so that the heat is transferred on the second path.

[0057] It should be noted that the first fan 120 rotates to transfer the heat generated by the heat generation module 110 from the side close to the first fan 120 to the side away from the first fan 120, so that the heat generated by the heat generation module 110 is transferred on the first path. Wherein, the first path can be as Figure 1As shown, starting from the first fan 120, it extends from right to left to the left side of the housing. The heat generated by the heat generation module 110 is transferred from the right side of the housing to the left side via the first fan 120.

[0058] It should be noted that when the second fan 130 rotates, it transports the heat generated by the heat generation module 110 from the side away from the second fan 130 to the side closer to the second fan 130, thus transferring the heat generated by the heat generation module 110 along a second path. This second path can be as follows: Figure 1 As shown, starting from the left side of the housing, it extends from left to right to the second fan 130. The heat generated by the heat generation module 110 is transferred from the left side of the housing to the right side via the second fan 130. As the heat is transferred along the second path, it flows through the battery pack 140, thereby heating the battery pack 140.

[0059] When the outdoor power supply is in heating mode, the first fan operates normally, transferring heat from the right side of the casing to the left side; the second fan operates, transferring heat from the left side to the right side; thus, the heat generated by the heat generation module is transferred to the battery pack, completing the heating of the battery pack, and then discharged from the casing.

[0060] Please see Figure 3 , Figure 3 This is a schematic diagram of an outdoor portable power bank battery temperature control system according to an embodiment of this application. Figure 3 As shown, the heat transfer path also includes a third path and a fourth path; the housing is also provided with a third opening and a fourth opening; the temperature control system also includes:

[0061] The third opening is located at the end of the third path; the first fan is located at the beginning of the third path.

[0062] The fourth opening is located at the end of the fourth path, and the second fan is located at the beginning of the fourth path. When the heat generated by the heat generation module is transmitted in the third path, it is transmitted to the outside of the housing through the third opening. When the heat generated by the battery pack is transmitted in the fourth path, it is transmitted to the outside of the housing through the fourth opening.

[0063] It should be noted that when the first fan 120 rotates, it transports the heat generated by the heat generation module 110 from the side closer to the first fan 120 to the side farther away from the first fan 120, thus transferring the heat generated by the heat generation module 110 along a third path. This third path can be as follows: Figure 3 As shown, starting from the first fan 120, the heat extends from right to left to the outside of the housing on the left side. The heat generated by the heat generation module 110 is transferred from the right side of the housing to the left side through the first fan 120, and then transferred to the outside of the housing through the third opening, thereby cooling the heat generation module.

[0064] It should be noted that the second fan 130 rotates, and the heat generated by the battery pack 140 is transported from the side close to the second fan 130 to the side away from the second fan 130, so that the heat generated by the battery pack 140 is transmitted on the fourth path. Wherein, the fourth path can be as shown, starting from the second fan 130, extending from right to left to the outside of the shell. Figure 3 The heat generated by the battery pack 140 is transmitted from the right side of the shell to the left side by the second fan 130, and when the heat is transmitted on the fourth path, the heat generated by the battery pack 140 is discharged from the fourth opening to the outside of the shell to achieve the cooling of the battery pack.

[0065] Please refer to Figure 2 、 3 , Figure 2 The outdoor mobile power supply battery temperature control system of an embodiment of the present application, in Figure 2 、 3 The temperature control system further comprises:

[0066] The first backflow prevention mechanism 180 has a closed state and an open state, and is arranged at the third opening;

[0067] The second backflow prevention mechanism 150 has a closed state and an open state, and is arranged at the fourth opening; when the heat generated by the heat generation module is transmitted on the first path and the second path, the first backflow prevention mechanism and the second backflow prevention mechanism are both in the closed state;

[0068] When the heat generated by the heat generation module is transmitted on the third path, and the heat generated by the battery pack is transmitted on the fourth path, the first backflow prevention mechanism and the second backflow prevention mechanism are both in the open state.

[0069] It should be noted that the first backflow prevention mechanism and the second backflow prevention mechanism are opened and closed together, and when the first backflow prevention mechanism and the second backflow prevention mechanism are in the closed state, the heat generated by the heat generation module and the battery pack cannot be discharged to the outside of the shell from the third opening and the fourth opening; when the first backflow prevention mechanism and the second backflow prevention mechanism are in the open state, the heat generated by the heat generation module and the battery pack can be discharged to the outside of the shell from the third opening and the fourth opening.

[0070] When the outdoor power supply is in the heating mode, the first fan and the second fan are normally operated, and the first fan inputs the heat from the right side of the shell to the left side; At this time, the speed of the second fan can be controlled to be higher than that of the first fan, so that a negative pressure appears inside the first backflow prevention mechanism and the second backflow prevention mechanism, and the first backflow prevention mechanism and the second backflow prevention mechanism are in the closed state; Then the second fan transports the heat from the left side to the right side; so that the heat generated by the heat generation module is transported to the battery pack, and the heating of the battery pack is completed, and then discharged from the shell.

[0071] When the outdoor power supply is in the heat dissipation mode, the first fan and the second fan are both in normal operation, but the rotating direction of the second fan at this time is opposite to that of the second fan in the heating mode, and the first fan inputs the heat generated by the heat generating module from the right side of the shell to the left side; because the first anti-backflow mechanism is opened in the direction of the air pressure, the heat generated by the heat generating module is discharged from the shell through the third opening hole, thereby achieving cooling of the heat generating module.

[0072] When the outdoor power supply is in the heat dissipation mode, the first fan and the second fan are both in normal operation, but the rotating direction of the second fan at this time is opposite to that of the second fan in the heating mode, and the second fan inputs the heat generated by the battery pack from the right side of the shell to the left side; because the second anti-backflow mechanism is opened in the direction of the air pressure, the heat generated by the battery pack is discharged from the shell through the fourth opening hole, thereby achieving cooling of the battery pack.

[0073] In an embodiment of the present application, the temperature control system further comprises:

[0074] The third fan 170 is arranged between the shell and the first anti-backflow mechanism and located at the end point of the third path, and the fourth fan 160 is arranged between the shell and the second anti-backflow mechanism and located at the end point of the fourth path. When the outdoor power supply is in the heat dissipation mode, the first anti-backflow mechanism and the second anti-backflow mechanism are in the open state, and the third fan and the fourth fan are also in the normal rotating state, the third fan makes the heat generated by the heat generating module quickly discharged from the shell, and the fourth fan makes the heat generated by the battery pack quickly discharged from the shell. Through the third fan and the fourth fan, the heat dissipation efficiency of the outdoor power supply can be accelerated.

[0075] In an embodiment of the present application, the temperature control system further comprises an AC power interface connected with the AC heater, for connecting an external AC power supply. When the battery pack needs to be heated, the AC heater is powered by the AC power supply, heat is generated by the AC heater, and then the battery pack is heated by the heat generated by the AC heater.

[0076] In an embodiment of the present application, the DC heater is electrically connected with the battery pack. The DC heater is powered by the battery pack to generate heat, and then the battery pack is heated by the heat generated by the DC heater.

[0077] In an embodiment of the present application, the temperature control system further comprises a temperature sensor, the temperature of the battery pack is detected by the temperature sensor, and then transmitted to the control module, and the corresponding heat generating module is controlled by the control module to generate heat to heat the battery pack.

[0078] In summary, the application does not need additional heating devices, and can use the waste heat generated by the inverter in the working process to heat the battery, improve the energy efficiency of the equipment; at the same time, the wind direction control in the equipment can be realized by starting and stopping of different fans in the equipment, fan speed control, and bidirectional fan direction control. In the heating mode, the heat of the inverter, AC heater and DC heater can be delivered to the battery pack, and in the cooling mode, the heat of the inverter and the battery pack can be directly delivered out of the equipment to cool the inverter and the battery pack.
