It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

Therefore, the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element without departing from the scope of the following technology. The term "and / or" includes a combination of multiple related items or any of the multiple related items.

[0022] As used herein, unless the context indicates otherwise, the singular form is intended to include the plural form, and it will be understood that the term "comprising" means the presence of stated features, quantities, steps, operations, elements, or combinations thereof, but does not exclude the presence or addition of one or more other features, quantities, steps, operations, elements, components, or combinations thereof.

[0023] Before the detailed description, it is intended to clarify that the division of components in this specification is divided only by the main function of each component. That is, two or more components to be described below can be combined into one component, or can be divided into two or more components according to more detailed functions. In addition to the main function of the component, each component to be described below can also perform some or all of the functions of other components, and some of the main functions of each component can be exclusively performed by other components.

[0024] In recent years, outdoor mobile power equipment has developed rapidly, and large capacity and high power output have become the main competitive advantages. However, in the low temperature process, low temperature will limit the input and output power of the battery. 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.

[0025] The existing technical solution is to install a heating wire or heating film on the surface of the battery, power the heating wire or heating film through the battery for heating, or use the battery current pulse to make the battery self-heating, thereby raising the battery temperature. The method of installing a heating wire or heating film on the surface of the battery will greatly consume the battery capacity. Moreover, since the heating wire is usually attached to the surface of the battery, this also limits the heating treatment to square batteries; and since the battery has thermal resistance and the heating film is usually attached to one of the surfaces of the battery, this causes the temperature of the battery surface contacted by the heating wire to be much higher than the uncontacted battery surface, and the temperature difference between different parts of the same battery is large. In addition, this method relies on battery power supply. When the temperature is lower than the battery discharge temperature threshold, the device will not be able to start the heating function. As for the method of heating through current pulses, there is a risk of damage to the internal structure of the battery, which is not conducive to battery safety.

[0026] In order to solve the above problems, an embodiment of the present application provides a method for heating batteries of an outdoor mobile power supply. The method realizes wind direction control in the device by starting and stopping different fans, controlling fan speed, and controlling bidirectional fan direction. In the heating mode, heat from the inverter, AC heater, and DC heater can be transferred to the battery pack, which solves the problem that the existing outdoor power supply has a single self-heating method and is limited by the battery type. At the same time, the heat generated during the operation of the inverter can be utilized to improve the energy efficiency of the battery during heating.

[0027] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of an outdoor mobile power battery temperature control system provided in an embodiment of the present application. Figure 1 The outdoor mobile power battery temperature control system includes: Inverter, AC heater, DC heater 110, inverter air inlet fan 120 or inverter air outlet fan 170, battery pack air inlet fan 130 (bidirectional fan), battery pack air outlet fan 160 (optional device), inverter air outlet backflow prevention device 180, battery pack air outlet backflow prevention device 150. By controlling the start and stop of each fan in the device, the fan speed, and the wind direction of the bidirectional fan, the device can dissipate heat from the inverter and battery 140 when in heat dissipation mode. When the device is in heating mode, the heat from the inverter, DC heater, and AC heater is transferred to the battery.

[0028] like Figure 2 As shown, when working in the battery heating mode, the inverter air inlet fan operates normally, the inverter air outlet fan and the battery pack air outlet fan are turned off, and the battery pack air inlet fan runs in reverse, wherein the speed of the battery pack air inlet fan is higher than that of the inverter air inlet fan, causing negative pressure to appear inside the inverter air outlet anti-backflow device and the battery pack anti-backflow device, thereby closing the two anti-backflow devices, thereby transporting the wind at the inverter to the battery pack and finally discharging it from the equipment.

[0029] like Figure 3 As shown in the figure, when working in the battery cooling mode, the inverter air inlet fan, inverter air outlet fan, battery pack air inlet fan, and battery pack air outlet fan are all running, and the battery pack air inlet fan is turned to run in the forward direction. The inverter air outlet anti-backflow device and the battery pack air outlet anti-backflow device are opened along the wind direction due to the influence of air pressure, and the heat of the inverter and battery pack is discharged along the wind direction.

[0030] See also Figure 4 , Figure 4 This is a flow chart of a method for heating an outdoor mobile power battery according to an embodiment of the present application. Figure 4 As shown, the outdoor mobile power battery heating method at least includes steps S410 to S430: Step S410, obtaining battery temperature; It should be noted that the battery temperature can be collected by a temperature sensor and then transmitted to the control module. Of course, the battery temperature can be understood as the battery surface temperature or the battery positive and negative terminal ear temperature, which can be collected by a temperature sensor.

[0031] Step S420, comparing the battery temperature with a preset battery temperature threshold; After the battery temperature is collected, the battery temperature is compared with the preset battery temperature threshold, and whether the battery needs to be heated is determined based on the comparison result. When the battery temperature is greater than the preset battery temperature threshold, the battery does not need to be heated. When the battery temperature is less than or equal to the preset battery temperature threshold, the battery needs to be heated to maintain or improve the battery performance.

[0032] It should be noted that, since the battery may work in a charging mode or a discharging mode, if the battery works in a charging mode, the preset battery temperature threshold is the battery charging temperature threshold; if the battery works in a discharging mode, the preset battery temperature threshold is the battery discharging temperature threshold. Of course, in addition to using the battery charging temperature threshold or the battery discharging temperature threshold as the preset battery temperature threshold, a temperature value may also be input by the user as the preset battery temperature threshold.

[0033] Step S430, when the battery temperature is lower than the battery temperature threshold, heating the battery by a preset heating method; the preset heating method includes at least one of the following: AC heating, DC heating, inverter heating; wherein AC heating is heating the battery by using the heat generated by an AC heater; DC heating is heating the battery by using the heat generated by a DC heater; inverter heating is heating the battery by using the heat generated by the inverter during operation.

[0034] AC heating mode: by connecting an external AC power supply, the AC heater is powered by the external AC power supply, the AC heater heating function is started, the fan speed and wind direction in the device are controlled, and the heat generated by the AC heater is transferred to the battery pack until the battery reaches the preset temperature or the AC power supply is disconnected; the AC power supply can be mains electricity.

[0035] DC heating mode: Start the DC heater, control the fan speed and wind direction in the device, and output the heat generated by the DC heater to the battery pack until the battery reaches the preset temperature or the battery pack SOC is lower than the preset value. The DC heater is powered by the battery to be heated.

[0036] Inverter heating: Connect an external load device or an AC power source, start the inverter, and transfer the heat generated by the inverter during operation to the battery pack by controlling the fan speed and wind direction inside the device until the battery temperature reaches the preset temperature or the SOC is greater than or equal to the preset battery SOC maximum threshold or less than or equal to the preset battery SOC retention threshold.

[0037] In the embodiment of the present application, the step of heating the battery by a preset heating method further includes: obtaining heating parameters; and determining the preset heating method according to the heating parameters. The heating parameters include: battery SOC, whether a load is connected, and whether an AC power supply is in place.

[0038] Since the heating system includes at least three heating methods, AC heating, DC heating, and inverter heating, how to select a corresponding heating method to heat the battery.

[0039] If AC power is in place, the battery can be heated by AC heating; or if the battery temperature is greater than the battery discharge temperature threshold and the battery SOC is greater than the preset battery SOC retention threshold, the battery can be heated by DC heating; or if the battery temperature is greater than the battery charge temperature threshold and AC power is in place and the battery SOC is less than the preset battery SOC maximum value threshold, or the battery temperature is greater than the battery discharge temperature threshold and a load is connected and the battery SOC is greater than the preset battery SOC retention threshold, the battery can be heated by inverter heating.

[0040] When the battery temperature is lower than the battery temperature threshold and the battery SOC is lower than the preset battery SOC retention threshold, the battery temperature can be increased by inserting an AC power supply and using an AC heater to solve the problem that the device cannot power the heating device by itself at low temperatures. The battery temperature can be increased by using a DC heater to speed up the heating rate. Moreover, when the battery temperature is greater than the battery discharge temperature threshold or the charging temperature threshold, the battery temperature can be increased by the heat generated by the inverter during the battery charging and discharging process, further improving the heating efficiency.

[0041] It should be noted that after the heating method is determined, the heating power, fan speed and direction are determined according to the preset stored corresponding relationship between the heating method and the heating power, the corresponding fan speed and the direction of rotation, and then the inverter air inlet fan, the inverter air outlet fan, the battery pack air inlet fan and the battery pack air outlet fan are controlled according to the determined heating power, fan speed and direction of rotation to achieve heating of the battery through the corresponding heating method. It should also be noted that the temperature thresholds of the battery, such as the battery discharge temperature threshold, the battery charge temperature threshold, the preset battery temperature threshold, and the preset battery SOC retention threshold can be pre-stored in the corresponding storage module. Of course, the battery discharge temperature threshold, the battery charge temperature threshold, the preset battery temperature threshold, and the preset battery SOC retention threshold can also be input through the user control input module.

[0042] It should also be noted that for heating the battery by AC heating, since AC heating is powered by an external AC power supply to the AC heater, before AC heating is performed, the presence of the AC power supply is first detected. If the AC power supply is in place, it is determined whether the battery temperature is less than the preset battery temperature threshold. Only if the battery temperature is less than the preset battery temperature threshold can the battery be heated by AC heating. If the AC power supply is not in place, the user needs to be prompted to insert the AC power supply, and then the AC heater is started by the AC power supply to heat the battery. Among them, the presence of AC power supply means that the external AC power supply is connected to the AC charging port of the device, the AC charging port is connected to the AC heater, and the AC power supply outputs current to the AC heater to heat the AC heater.

[0043] It should be noted that the three heating methods of AC heating, DC heating, and inverter heating are in parallel, and users can set them in advance. For example, one of the three heating methods is used to heat the battery, or any two of the three heating methods are used to heat the battery, or all three heating methods are used to heat the battery at the same time. Users can run the corresponding heating method according to actual conditions. After the heating mode is turned on, the speed and wind direction of the fan are controlled to deliver the hot air from the AC heater, DC heater, or inverter to the battery pack to complete the heating of the battery.

[0044] In the embodiment of the present application, if the battery SOC is lower than the preset battery SOC retention threshold, DC heating is stopped; if the battery temperature is greater than the battery temperature threshold, AC heating and DC heating are stopped; if the battery temperature is greater than the battery optimal temperature threshold or the battery SOC is greater than or equal to the preset battery SOC maximum value threshold or less than or equal to the preset battery SOC retention threshold, inverter heating is stopped. The battery optimal temperature threshold is the battery discharge temperature threshold or the battery charging temperature threshold + the preset temperature. The preset temperature here can be selected according to the actual situation and is not limited here. For example, the preset temperature is any value between 10 and 20 degrees.

[0045] It should be noted that if all three heating methods are stopped but the equipment still needs to be charged and discharged, the heating mode is exited and the cooling mode is entered. The system controls the fan module, adjusts the speed and direction of the inverter air inlet fan, inverter air outlet fan, battery pack air outlet fan, and battery pack air inlet fan, and directly sends the heat generated by the inverter and the self-heating of the battery during the charging and discharging process out of the device and no longer to the battery pack.

[0046] This application realizes wind direction control inside the equipment by starting and stopping different fans, controlling fan speed, and controlling bidirectional fan direction. In heating mode, the heat from the inverter, AC heater, and DC heater can be transferred to the battery pack. In cooling mode, the heat from the inverter and battery pack can be directly transferred out of the equipment to dissipate heat from the inverter and battery pack, solving the problem that the existing outdoor power supply has a single self-heating method and is limited by the battery type. At the same time, the heat generated during the operation of the inverter can be used to improve the energy efficiency of the battery during heating.

[0047] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution.
