Abstract
A charging device includes: first and second capacitors connected in series between a positive electrode and a negative electrode of a storage battery; first and second switching elements each including a plurality of switching elements; first and second terminals; first and second changeover switches; and a control circuit controlling opening and closing of the first switching elements and the second switching elements to switch between a first state to charge the first capacitor with an external direct-current power source and a second state to charge the second capacitor with the external direct-current power source.
