[0035] S101 , obtaining the power consumption of the computing board in real time through the power detection module 3 .

[0036] S102, when the power consumption of the computing board is greater than the maximum power of the power supply 1, the power supply 2 supplies power to the computing board 1 at the maximum power. At the same time, the battery management module 5 connects the battery 4 and the computing board 1 so that the battery 4 supplies power to the computing board 1.

[0037] S103. When the power consumption of the computing board is less than the maximum power of the power supply 1:

[0038] If the battery 4 is not fully charged, the power supply 2 is used to supply power to the computing board 1 at the maximum power. At the same time, the battery management module 5 connects the battery 4 and the power supply 2, and the power supply 2 charges the battery 4.

[0039] If the battery 4 has reached a fully charged state, the power supply 2 is used to supply power to the computing board 1 with a power equal to the power consumption of the computing board. At this time, the battery management module 5 is not connected to the battery 4 and the power supply 2 .

[0040] S104. When the power consumption of the computing board is equal to the maximum power of the power supply 2, the power supply 2 supplies power to the computing board 1 at the maximum power.

[0041] Among them, Figure 2As shown, the power supply 2 is connected to the computing board 1 to form a first power supply channel between the power supply 2 and the computing board 1. The power supply 2 is connected to the battery 4 via the battery management module 5 to form a charging channel between the power supply 2 and the battery 4. The battery 4 is connected to the computing board 1 via the battery management module 5 to form a second power supply channel between the battery 4 and the computing board 1. The power detection module 3 can use a common voltmeter and ammeter. It is connected to the computing board 1 to detect the power consumption of the computing board. The power detection module 3 is also connected to the battery management module 5 and the power supply 2 to send the detected power consumption of the computing board to the battery management module 5 and the power supply 2 respectively. The battery management module 5 is used to detect the power state of the battery 4, and open and close the charging channel and the second power supply channel according to the power consumption of the computing board and the power state of the battery 4. It is also connected to the power supply 2 to send the power state signal of the battery 4 (whether it is fully charged) to the power supply 2, so that the power supply 2 determines the output power according to the power consumption of the computing board and the power state of the battery 4. A power management unit can be set in the power supply 2 to control the output power of the power supply 2 according to the power consumption of the computing board and the power state of the battery 4.

[0042] Figure 5 The diagram shows the relationship between the maximum power of power supply 2 and the power consumption of the computing board. In a time period T, the power consumption C(t) of the computing board changes dynamically all the time, and the computing board 1 is not always in the state of maximum power consumption. When the power consumption C(t) of the computing board is less than the maximum power of the power supply P max When the power source 2 outputs energy that is not only delivered to the computing board 1, but also has some remaining energy, which is stored by the battery 4. Figure 6 As shown, the maximum power P max is the baseline, the maximum power of the power supply P max The difference between the power consumption of the computing board C(t) and the power delivered by the power supply to the battery is the maximum power of the power supply P max The shaded area below the baseline represents the maximum energy the battery can store.

[0043] like Figure 5 As shown, when the power consumption C(t) of the computing board is greater than the maximum power of the power supply P max If the computing board 1 is powered only by the power supply 2, it will not work properly due to insufficient power supply. At this time, the battery 4 can be connected to release the energy stored in the battery 4, and the computing board 1 is powered by the power supply 2 and the battery 4 together. max When it is less than the power consumption C(t) of the computing board, computing board 1 can also work normally. Figure 6 As shown, the power consumption C(t) of the computing board and the maximum power P of the power supply max The difference between them is the power transmitted by the battery to the computing board, and the maximum power of the power supply is P maxThe area of ​​the shaded part above the baseline represents the energy delivered by the battery to the computing board. In order for the computing board to operate normally, it is necessary to ensure that the energy delivered by the power supply to the battery is greater than the energy delivered by the battery to the computing board, that is, the maximum power of the power supply P max The area of ​​the shaded portion below the baseline must be larger than the area of ​​the shaded portion above it.

[0044] Therefore, the maximum power of the power supply and the power consumption of the computing board must satisfy the following formula:

[0045]

[0046] Among them, P max represents the maximum power of power supply 2, C(t) represents the power consumption of the computing board, and Ts represents the period of time during which C(t) is less than P max time, represents the energy delivered by power source 2 to battery 4 within the cycle time T, μ represents the charge and discharge efficiency of battery 4, represents the energy that battery 4 can deliver to computing board 1, and Tc represents the period of time T during which C(t) is greater than P max time, Represents the energy that the battery 4 needs to deliver to the computing board 1 within the cycle time T.

[0047] In practical applications, the maximum power of the power supply 1 can be determined according to the above formula to avoid an increase in cost due to an overly large power supply.

[0048] In practical applications, an oversized battery will increase the cost. Assume the battery capacity is W. bc , battery capacity W bc The size satisfies the following formula:

[0061] Figure 5 The diagram shows the relationship between the maximum power of power supply 2 and the power consumption of the computing board. In a time period T, the power consumption C(t) of the computing board changes dynamically all the time, and the computing board 1 is not always in the state of maximum power consumption. When the power consumption C(t) of the computing board is less than the maximum power of the power supply P max When the power source 2 outputs energy that is not only delivered to the computing board 1, but also has some remaining energy, which is stored by the battery 4. Figure 6 As shown, the maximum power P max is the baseline, the maximum power of the power supply P max The difference between the power consumption of the computing board C(t) and the power delivered by the power supply to the battery is the maximum power of the power supply P max The shaded area below the baseline represents the maximum energy the battery can store.

[0062] like Figure 5 As shown, when the power consumption C(t) of the computing board is greater than the maximum power of the power supply P max If the computing board 1 is powered only by the power supply 2, it will not work properly due to insufficient power supply.
