[0018] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto.

[0019] Please see Figure 1 This utility model provides a computer power control system, which includes a temperature detection module, a control module, a power module, and a computer data processor. The power module includes a first battery pack, a second battery pack, a first switching transistor K1, a second switching transistor K2, a third switching transistor K3, a first freewheeling diode FD1, a second freewheeling diode FD2, a third freewheeling diode FD3, a fourth freewheeling diode FD4, an inductor L, and a SOC acquisition module.

[0020] The first battery pack's input terminal is connected to the input terminal of the first freewheeling diode FD1 and one end of the inductor L. The first battery pack's output terminal is connected to the source terminal of the third switching transistor K3, the input terminal of the fourth freewheeling diode FD4, the output terminal of the second battery pack, and the computer data processor. The first freewheeling diode FD1's output terminal is connected to the drain terminal of the second switching transistor K2, the output terminal of the third freewheeling diode FD3, the input terminal of the second freewheeling diode FD2, the source terminal of the first switching transistor K1, and the computer data processor. The second freewheeling diode FD2's output terminal is connected to the drain terminal of the first switching transistor K1 and the input terminal of the second battery pack. The other end of the inductor L is connected to the source terminal of the second switching transistor K2, the drain terminal of the third switching transistor K3, the input terminal of the third freewheeling diode FD3, and the output terminal of the fourth freewheeling diode FD4. The gate terminals of the first switching transistor K1, the second switching transistor K2, and the third switching transistor K3 are all connected to the output terminal of the control module. The SOC acquisition module is connected to both ends of the second battery pack. The temperature detection module and the SOC acquisition module are respectively connected to the input terminal of the control module.

[0021] In this embodiment of the invention, the first battery pack is a conventional lithium battery pack, and the second battery pack is a supercapacitor. The conventional lithium battery pack is composed of conventional lithium batteries. The maximum voltage of the conventional lithium battery pack is higher than the maximum voltage of the supercapacitor, to ensure that the supercapacitor can be charged to its maximum voltage.

[0022] In this embodiment of the invention, the first battery pack is a high-energy lithium battery pack, and the second battery pack is a high-power lithium battery pack. Because modified lithium batteries have higher energy density, smaller size, and lighter weight, they have a promising development trend. Therefore, this invention more preferably designs the first battery pack as a high-energy lithium battery pack and the second battery pack as a high-power lithium battery pack. The high-energy lithium battery pack is composed of high-energy-density lithium batteries with the same modification, and the high-power lithium battery pack is composed of high-power-density lithium batteries with the same modification. The maximum voltage of the high-energy lithium battery pack is higher than the maximum voltage of the supercapacitor to ensure that the high-power lithium battery pack can be charged to its maximum voltage.

[0023] In this embodiment of the invention, the first switching transistor K1, the second switching transistor K2, and the third switching transistor K3 are MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors) or IGBTs (Insulated Gate Bipolar Transistors). It should be noted that the first switching transistor K1, the second switching transistor K2, and the third switching transistor K3 are not limited to MOSFETs or IGBTs; for example, they can also be transistors with switching functions.

[0024] In this embodiment of the invention, the temperature detection module can be a temperature sensor, which is mainly used to detect the temperature of the current environment in which the computer is working in real time.

[0025] In this embodiment of the invention, the control module can be an ARM controller, which is mainly used to generate control signals based on the temperature detected by the temperature detection module and the SOC (State of Charge) value obtained by the SOC acquisition module, so as to control the operation of the first battery pack and the second battery pack in the power module.

[0026] The specific circuit structure of the SOC acquisition module in this embodiment is not limited; any circuit that can acquire the SOC value of the battery is acceptable.

[0027] In this embodiment of the utility model, the power module can realize different power supply methods in low-temperature environments and non-low-temperature environments, specifically:

[0028] When the computer operates in a low-temperature environment—that is, when the ambient temperature detected by the temperature detection module is below the low-temperature threshold—the control module generates a control signal based on the detected ambient temperature. This signal turns on the first switching transistor K1, the second switching transistor K2, the third switching transistor K3, the third freewheeling diode FD3, and the fourth freewheeling diode FD4, while turning off the first freewheeling diode FD1 and the second freewheeling diode FD2. The first battery pack then provides power through the inductor L and the third freewheeling diode FD3, while the second battery pack provides power directly through the first switching transistor K1. This allows both the first and second battery packs to jointly power the computer's data processor. Low temperatures significantly impact battery performance; by using both battery packs, the normal power supply to the computer's data processor can be better guaranteed.

[0029] When the computer operates in a non-low-temperature environment, i.e., when the ambient temperature detected by the temperature detection module is higher than or equal to the low-temperature threshold, if the SOC value of the second battery pack obtained by the SOC acquisition module is lower than the lower limit of the SOC value, the control module generates a control signal based on the ambient temperature detected by the temperature detection module and the SOC value of the second battery pack obtained by the SOC acquisition module. This signal controls the first switching transistor K1 to turn off and the first freewheeling diode FD1 to turn off, while controlling the third freewheeling diode FD3, the second switching transistor K2, the fourth freewheeling diode FD4, the third switching transistor K3, and the second freewheeling diode FD2 to turn on. Then, the first battery pack outputs power through the boost voltage of the inductor L and the third freewheeling diode FD3, while simultaneously charging the second battery pack through the second freewheeling diode FD2. This allows the first battery pack to power the computer data processor independently. In this case, the voltage can be boosted through the inductor L and the third freewheeling diode FD3, thereby enabling the second battery pack to be quickly charged through the second freewheeling diode FD2.

[0030] If the SOC value of the second battery pack obtained by the SOC acquisition module reaches the upper limit of the SOC value but the SOC value of the second battery pack does not reach 100%, the control module generates a control signal based on the ambient temperature detected by the temperature detection module and the SOC value of the second battery pack obtained by the SOC acquisition module. This signal controls the third freewheeling diode FD3, the second switching transistor K2, the fourth freewheeling diode FD4, the third switching transistor K3, and the first switching transistor K1 to turn off, and controls the first freewheeling diode FD1 and the second freewheeling diode FD2 to turn on. Then, the first battery pack directly outputs power through the first freewheeling diode FD1, and at the same time, charges the second battery pack through the second freewheeling diode FD2, thereby enabling the first battery pack to supply power to the computer data processor independently. At this time, the second battery pack has sufficient power but is not fully charged. To protect the performance of the second battery pack, a smooth charging process is needed, that is, the first battery pack is switched to the direct output power supply mode, and the boost-buck converter stops working, reducing the energy loss through the boost-buck converter.

[0031] If the SOC value of the second battery pack obtained by the SOC acquisition module reaches 100%, the control module generates a control signal based on the ambient temperature detected by the temperature detection module and the SOC value of the second battery pack obtained by the SOC acquisition module. This signal controls the second freewheeling diode FD2 and the first freewheeling diode FD1 to turn off, and controls the third freewheeling diode FD3, the second switching transistor K2, the fourth freewheeling diode FD4, the third switching transistor K3, and the first switching transistor K1 to turn on. Then, the second battery pack directly outputs power through the first switching transistor K1, and simultaneously charges the first battery pack through the inductor L and the third freewheeling diode FD3, thereby enabling the second battery pack to independently power the computer data processor. At this time, the first battery pack is fully charged and can absorb excess power through the boost-buck converter.

[0032] The different power supply methods described above for low-temperature and non-low-temperature environments are merely descriptions of the actual working process of the power module, which is determined by the structural design of the power module itself.

[0033] Here, the low temperature threshold can be designed to be 10℃, or it can be set according to actual needs; the lower limit of the SOC value of the first battery pack and the second battery pack can be designed to be 40%, and the upper limit of the SOC value of the first battery pack and the second battery pack can be designed to be 90%.

[0034] Further, please see Figure 2 The computer power control system proposed in this utility model further includes a cooling module and a heating module; the cooling module and the heating module are respectively connected to the control module. In this embodiment, the temperature detection module monitors the current ambient temperature of the computer in real time. For example, if the current ambient temperature is too high, the control module generates a control signal to activate the cooling module, such as a fan, to lower the ambient temperature and reduce the impact of high ambient temperature on the computer's battery performance. Conversely, if the current ambient temperature is too low, the control module generates a control signal to activate the heating module, such as a heater, to raise the ambient temperature and reduce the impact of low ambient temperature on the computer's battery performance. The cooling and heating modules better assist the power module in supplying power to the computer's data processor.

[0035] In summary, the computer power control system proposed in this utility model uses a temperature detection module to monitor the ambient temperature in real time. Based on the detected ambient temperature, it determines the first and / or second battery packs in the designed power module to supply power to the computer data processor. This enables the computer equipment to operate normally for a longer period of time in both low-temperature and non-low-temperature environments, significantly reducing power supply failures in low-temperature environments. Furthermore, the designed power module can effectively extend the lifespan of both the first and second battery packs.
