Embodiment 1
[0041] figure 1 It is a flow chart of the steps of the DC power supply method described in the embodiment of the present invention.
[0042] Such as figure 1 As shown, the embodiment of the present invention provides a DC power supply method, which is applied to a low-voltage DC power supply for powering a charged load, including the following steps:
[0043] Step 101: Obtain the current state of charge of the energy storage element in the charged load.
[0044] It should be noted that the load to be charged may be an electric or hybrid vehicle, and may also be a device requiring DC power. The energy storage element may be a storage battery, or an electronic component with energy storage function. State of charge refers to the percentage of charge remaining in the energy storage element.
[0045] Step 102: Determine whether the current state of charge is greater than the first state of charge threshold, if yes, execute step 103, if not, execute step 106.
[0046]Step 103:...
