The invention discloses an equalization circuit, a charging circuit and a vehicle-mounted charger. The equalization circuit comprises an energy storage circuit, N switching circuits and a control circuit, the input ends of the N switching circuits are connected with N battery modules in a one-to-one correspondence manner, and the output ends of the N switching circuits are connected with the energy storage circuit; the control circuit is connected with the controlled ends of the N switching circuits and controls the switching circuits corresponding to the two adjacent battery modules to be alternately turned on so as to control the two adjacent battery modules to alternately charge and discharge the energy storage circuit. Therefore, the voltage balance between the two battery modules is realized, and the voltage balance between the battery modules is realized.
