[0026] See Figures 1 to 5 , Figure 1 is a block diagram of the mobile power supply 100 provided by the first embodiment of the present utility model; Figure 2 is a block diagram of the mobile power supply 100 provided by the second embodiment of the present utility model; Figure 3 is a block diagram of the mobile power supply 100 provided by the third embodiment of the present utility model; Figure 4 is a block diagram of the mobile power supply 100 provided by the fourth embodiment of the present utility model; Figure 5It is a block diagram of the mobile power supply 100 provided by the fifth embodiment of the present utility model. As shown in the figure, the mobile power supply 100 includes a control module 10, a power supply module 20, and a temperature adjustment module 30; the power supply module 20 is connected to the control module 10, and the power supply module 20 includes a plurality of batteries connected in series and / or in parallel; the temperature adjustment module 30 is connected to the control module 10 for adjusting the temperature of the mobile power supply 100; wherein, the control module 10 adjusts the temperature of the mobile power supply 100 through the temperature adjustment module 30 so that the mobile power supply 100 is at the optimal charging temperature.

[0027] Specifically, the mobile power supply 100 may include a control module 10, a power supply module 20, and a temperature adjustment module 30. The control module 10 is used to control the operation of the mobile power supply 100 and manage the charging and discharging of the power supply module 20. The power supply module 20 may include a plurality of batteries, and the plurality of batteries are connected in series and / or in parallel. For example, a plurality of batteries may be first connected in series to form a battery pack, and then a plurality of battery packs may be connected in parallel, thereby increasing the capacity of the mobile power supply 100. Preferably, the power supply module 20 may include seven battery packs connected in parallel, and each battery pack includes six batteries connected in series, and can charge multiple drones simultaneously. For example, the maximum voltage of the above seven battery packs connected in parallel may be 25.2V, and the maximum capacity is 35Ah, then it can simultaneously satisfy the charging of six drones with a capacity of 3Ah three times or more.

[0028] The temperature adjustment module 30 is connected to the control module 10 for adjusting the temperature of the mobile power supply 100. It can increase or decrease the temperature of the mobile power supply 100 under the control of the control module 10. For example, when the temperature of the mobile power supply 100 is relatively high, the control module 10 controls the temperature adjustment module 30 to lower the temperature of the mobile power supply 100. When the temperature of the mobile power supply 100 is relatively low, the control module 10 controls the temperature adjustment module 30 to increase the temperature of the mobile power supply 100. When the temperature of the mobile power supply 100 is relatively high, its electronic components, when the temperature of the mobile power supply 100 is relatively low, the charging efficiency is relatively low. The temperature of the mobile power supply 100 can be adjusted through the temperature adjustment module 30 so that the temperature of the mobile power supply 100 is maintained at an optimal charging temperature.

[0029] See Figure 3 As a further embodiment, the control module 10 includes a main control module 11 and a power management module 12 connected to the main control module 11; the power management module 12 is also connected to the power supply module 20 and the temperature adjustment module 30.

[0030] Among them, the control module 10 may include a main control module 11 and a power management module 12. The control module 10 may include an MCU, which serves as the core control unit of the mobile power supply 100 and has data processing capabilities. It can receive battery information from the power management module 12 in real time, including but not limited to key parameters such as voltage, current, temperature, and battery capacity. By reading these data, the MCU can understand the working state of the mobile unit and facilitate timely control. In addition, when the mobile power supply 100 is in abnormal states such as overheating, overvoltage, undervoltage, and overcurrent, the mobile power supply 100 can process it in a timely manner and send out warning information to remind the user.

[0031] When the mobile power supply 100 is equipped with a display screen, the MCU can display key parameters such as the read voltage, current, temperature, and battery capacity on the display screen or the digital tube, facilitating the user to intuitively understand the state of the mobile power supply 100.

[0032] The power management module 12 may be a power management chip, which is used to protect the battery against overvoltage, undervoltage, overheating, underheating, overcurrent, short circuit, etc., and to read the basic state information of the battery, such as voltage, current, and power, and then transmit it to the MCU.

[0034] Among them, the temperature adjustment module 30 may include a heating module 31 and a cooling module 32. The heating module 31 is used to increase the temperature of the mobile power supply 100, and the cooling module 32 is used to decrease the temperature of the mobile power supply 100. Specifically, the heating module 31 is used to increase the temperature of the battery cells of the mobile power supply 100, and the cooling module is used to decrease the temperature of the battery cells of the mobile power supply 100. The heating module 31 may include a heating resistor, which is connected to the main control module 11 and can be heated or cooled under the control of the main control module 11. When heating, it can increase the temperature of the battery cells.

[0035] The cooling module 32 may include a fan, which reduces the temperature of the battery cells by air cooling. That is, when the temperature of the battery cells is relatively high, the fan starts and discharges the hot air from the mobile power supply 100 to reduce the temperature of the battery cells. At the same time, the rotation speed of the fan can also be adjusted according to different temperatures. The higher the temperature, the higher the rotation speed of the fan.

[0036] See Figure 5 , as a further embodiment, it further includes a balancing module 40, and the balancing module 40 is respectively connected to the power management module 12 and the power supply module 20.

[0037] Among them, the balancing module 40 may include a balancing resistor and a MOS transistor. Generally, one battery cell corresponds to one balancing resistor and one MOS transistor, and the voltages between different battery cells are balanced through a discharging operation. For example, the power management module 12 determines the voltage of each battery cell by detecting each balancing resistor. When the voltage difference between different battery cells is large, a balancing operation is started. The battery cell with the highest voltage among all the battery cells is identified, and the voltage of this battery cell is reduced to the lowest voltage of the other battery cells. The specific voltage reduction method may be to turn on the MOS transistor corresponding to the battery cell. After the MOS transistor is turned on, the battery cell discharges to the matching balancing resistor and is converted into heat energy for release, completing the reduction of the battery cell voltage. If the voltage difference between different battery cells is still large after the voltage reduction of the battery cell with the highest voltage, the above steps can be repeated until the voltage difference is controlled within a threshold range. This threshold may be 18 mV, that is, when it is higher than 18 mV, the balancing operation is started.

[0040] As a further embodiment, it further includes a display module 60, and the display module 60 is connected to the main control module 11.

[0041] Among them, the display module 60 may be a digital tube, which is responsible for receiving voltage, current, and temperature information from the main control module 11 and can display them on its display screen. Secondly, when the main control module 11 sends error messages to it, it can display the error messages on its display screen, such as overvoltage error, undervoltage error, overtemperature error, and undertemperature error.
