Embodiment 1
[0026] In order to solve the problems of low step-down conversion efficiency, slow charging speed and serious heat generation in the existing charging control method, Embodiment 1 of the present invention provides a charging control method, such as figure 2 , which is a schematic flow chart of the steps of the charging control method described in Embodiment 1 of the present invention. Specifically, by figure 2 It can be seen that the charging control method may include the following steps:
[0027] Step 201: collecting the initial charging voltage and initial charging current of the battery to be charged;
[0028] Step 202: Judging that the initial charging voltage is greater than a set voltage threshold and the initial charging current is greater than a set current threshold;
[0029] Step 203: If yes, control the power-on of the charge pump conversion circuit and the power-off of the step-down conversion circuit, and control the adapter to output dynamic voltage and dyna...
Embodiment 2
[0118] Based on the same inventive concept as the embodiment of the present invention, Embodiment 2 of the present invention provides a charging control device, such as Figure 8 As shown in , it is a schematic structural diagram of the charging control device described in Embodiment 2 of the present invention. Specifically, by Figure 8 It can be seen that the charging control device may include:
[0119] The collection module 81 can be used to collect the initial charging voltage and initial charging current of the battery to be charged;
[0120] The control module 82 can be used to judge that the initial charging voltage is greater than the set voltage threshold, and the initial charging current is greater than the set current threshold, and if so, control the power-on of the charge pump conversion circuit and the power-off of the step-down conversion circuit , and control the adapter to output a dynamic voltage and a dynamic current to the charge pump conversion circuit,...
