The invention discloses a strong electricity charging and discharging control method of a hybrid electric vehicle and an apparatus thereof, which comprise a whole vehicle controller and a cross end voltage detection circuit, wherein the whole vehicle controller is in electric connection with the cross end voltage detection circuit; when a request of charging strong electricity is sent by the whole vehicle controller, pre-charging and strong electricity charging operations are carried out by the cross end voltage detection circuit; and when a request of discharging strong electricity is sent by the whole vehicle controller, strong electricity discharging operation is carried out by the cross end voltage detection circuit. According to the invention, instantaneous electricity current is prevented from being too big through the pre-charging process; the time sequence of charging and discharging the strong electricity is accurate and reliable; and the safety of a high-voltage electricity apparatus and the safety of the whole vehicle are fully protected.
