步骤226：根据所述规律序列及所述用电模块的总数确定各所述用电模块的供电电压范围，使得各所述供电电压范围的最大值不同，且任一用电模块中的各用电电路所需供电电压的最大值均小于或等于所述用电模块的供电电压范围的最大值。Step 226: Determine the power supply voltage range of each of the power consumption modules according to the regular sequence and the total number of the power consumption modules, so that the maximum value of each of the power supply voltage ranges is different, and the power supply voltage of each power consumption module is different. The maximum value of the power supply voltage required by the electrical circuit is all less than or equal to the maximum value of the power supply voltage range of the power consumption module.
具体地，例如，对于一个包括12个需要的供电电压的幅值不同的用电电路来说，可以将这12个用电电路按照所需供电电压的幅值升序排列或降序排列以形成规律序列。若记这12个按照所需供电电压的幅值升序排列的用电电路分别对应的所需供电电压的最大值为v1、v2、v3、……v12，则可以形成升序排列的规律序列a＝[v1,v2,v3,……v12]；若确定提供4个子电源模块为这12个用电电路供电合适，则可以根据规律序列a确定这4个用电模块的供电电压范围，例如，可以依次设置这4个用电模块的供电电压范围的最大值为V_1、V_2、V_3及V_4，其中，V_1<V_2<V_3<V_4，可以设置v3≦V_1，v6≦V_2，v9≦V_3且v12≦V_4；即，设置供电电压范围的最大值为V_1的用电模块包括所需供电电压的最大值分别为v1、v2及v3的三个用电电路，设置供电电压范围的最大值为V_2的用电模块包括所需供电电压的最大值分别为v4、v5及v6的三个用电电路，设置供电电压范围的最大值为V_3的用电模块包括所需供电电压的最大值分别为v7、v8及v9的三个用电电路，设置供电电压范围的最大值为V_4的用电模块包括所需供电电压的最大值分别为v10、v11及v12的三个用电电路；然后利用这4个相互独立的子电源模块形成的移动设备供电电源为这4个用电模块供电。由于提供的子电源模块输出电压的最大值与对应连接的用电模块所需供电电压的最大值相匹配，避免利用输入输出电压差比较大的功率转换器将电源提供的电压升压至移动设备内部的高压用电模块所需的工作电压，从而避免了因该功率转换器的输入输出电压差较大引发的发热问题，提高了电源储能的利用率的同时相对延长了移动设备的待机使用时间。Specifically, for example, for a power supply circuit including 12 required power supply voltages with different amplitudes, the 12 power supply circuits can be arranged in ascending order or descending order according to the amplitude of the required power supply voltage to form a regular sequence . If the maximum values of the required power supply voltages corresponding to the 12 power-consuming circuits arranged in ascending order of the required power supply voltage amplitudes are recorded as v1, v2, v3, ... v12, a regular sequence of ascending order can be formed a= [v1,v2,v3,...v12]; If it is determined that it is appropriate to provide 4 sub-power modules to supply power to these 12 power-consuming circuits, the power supply voltage range of these 4 power-consuming modules can be determined according to the regular sequence a. For example, you can Set the maximum value of the power supply voltage range of these four power modules to V_1, V_2, V_3 and V_4 in turn, where V_1<V_2<V_3<V_4, you can set v3≦V_1, v6≦V_2, v9≦V_3 and v12≦ V_4; that is, the power module whose maximum value of the power supply voltage range is set to V_1 includes three power circuits whose maximum values of the required power supply voltage are v1, v2 and v3 respectively, and the power module whose maximum value of the power supply voltage range is set to V_2 The power module includes three power circuits whose maximum required power supply voltages are v4, v5, and v6, respectively. The power module whose maximum power supply voltage range is set to V_3 includes the required power supply voltages whose maximum values are v7 and v8, respectively. And the three power-consuming circuits of v9, the power-consuming module whose maximum value of the power supply voltage range is set to V_4 includes three power-consuming circuits whose maximum values of the required power supply voltage are v10, v11 and v12 respectively; then use these four mutual The mobile device power supply formed by the independent sub-power modules supplies power to the four power modules. Since the maximum value of the output voltage of the provided sub-power module matches the maximum value of the power supply voltage required by the corresponding connected power module, it is avoided to use a power converter with a large input-output voltage difference to boost the voltage provided by the power supply to the mobile device. The working voltage required by the internal high-voltage power module, thus avoiding the heating problem caused by the large input and output voltage difference of the power converter, improving the utilization rate of power storage, and relatively prolonging the standby use of mobile devices. time.

步骤242：设置任一所述用电模块对应的子电源模块的输出电压的最大值，与所述用电模块的供电电压范围的最大值的差值位于预设的阈值范围。Step 242: Set the maximum value of the output voltage of the sub-power supply module corresponding to any of the power consumption modules, and the difference between the maximum value of the power supply voltage range of the power consumption module and the maximum value of the power supply voltage range is within a preset threshold range.
具体地，由于设置任一所述用电模块对应的子电源模块的输出电压的最大值，与所述用电模块的供电电压范围的最大值的差值位于预设的阈值范围，使得子电源模块输出电压的最大值与对应连接的用电模块所需供电电压的最大值相匹配，从而使得子电源模块可以直接为与其连接的用电模块供电，避免引入功率转换模块而产生不必要的电能损耗及热量。Specifically, since the maximum value of the output voltage of the sub power supply module corresponding to any of the power consumption modules is set, the difference between the maximum value of the power supply voltage range of the power consumption module and the maximum value of the power supply voltage range of the power consumption module is located in the preset threshold range, so that the sub power supply The maximum value of the output voltage of the module matches the maximum value of the power supply voltage required by the corresponding connected power module, so that the sub-power module can directly supply power to the power module connected to it, and avoid unnecessary power generation due to the introduction of the power conversion module. loss and heat.

具体地，请继续参考图4，由于子电源模块在为与之连接的用电模块供电的过程中，其存储的电能不断地被消耗，导致其输出的电压幅值不断地降低，为了避免产生在子电源模块中仍然储存有电能，而输出电压的幅值难以满足对应用电模块的供电需求的情况，可以设置所述用电模块经由功率转换电路与对应的子电源模块连接，所述功率转换电路用于将所述子电源模块的输出电压幅值，转换为所述用电模块所需的电压幅值，从而最大化利用该子电源模块中存储的电能。Specifically, please continue to refer to FIG. 4 , since the stored electric energy of the sub-power module is continuously consumed in the process of supplying power to the power-consuming module connected to it, the output voltage amplitude of the sub-power module is continuously reduced. In the case where electrical energy is still stored in the sub-power supply module, but the amplitude of the output voltage is difficult to meet the power supply demand for the application electrical module, the power-consuming module can be set to be connected to the corresponding sub-power supply module via a power conversion circuit, and the power The conversion circuit is used for converting the output voltage amplitude of the sub-power module into the voltage amplitude required by the power consumption module, so as to maximize the utilization of the electric energy stored in the sub-power module.
