A charging device includes a first DC convertor and controller. The first DC convertor is configured to convert a DC signal outputted by a power battery to a DC signal required for a storage battery. The first DC convertor includes a first half-bridge logical link control (LLC) circuit and a second half-bridge LLC circuit arranged in parallel. The controller is connected with the first half-bridge LLC circuit and the second half-bridge LLC circuit and configured to acquire a total output current of the first DC convertor, and control the first half-bridge LLC circuit and the second half-bridge LLC circuit to operate alternately when the total output current is less than a current threshold.
