1. A charging method applied to the charging system, wherein the charging system comprises: a first battery; a second battery having a capacity smaller than that of the first battery; a switch device disposed outside the second battery and connected to the second battery; a charging component connected to the first battery and connected to the second battery via the switch device, wherein the charging component is configured to output a charging current to the first battery and the second battery; and a control component connected to the first battery and the second battery, wherein the control component is configured to detect remaining capacity of the first battery and the second battery during a charging process, and control the switch device to turn on or turn off based on the remaining capacity,
wherein the method comprises:
obtaining the remaining capacity of the first battery and the second battery during the charging process;
in response to the remaining capacity of the second battery increasing to a first preset threshold, controlling the switch device to disconnect the second battery from the charging component, and keeping the charging component charging the first battery; and
in response to the remaining capacity of the first battery increasing to a second preset threshold, controlling the switch device to connect the second battery with the charging component, and keeping the charging component charging the first battery.
