Range extender power time control method

The invention discloses a range extender power time control method. The method specifically includes the following steps that (1) when a range extender obtains a power output request from a whole vehicle controller, a control unit of the range extender obtains time which is set through transferring from a current power point to a demanded power point; (2) the range extender selects a plurality of power points between the current power point and the demanded power point in transferring according to a certain control algorithm; (3) the control unit of the range extender obtains all set time from former power point transferred to the power point, and all the time are calculated through accumulation to obtain total time; and (4) the obtained total time is consistent with the set time from the current power point transferred to the demanded power point. The range extender power time control method has the beneficial effects that the controllability of process time is achieved during switching of different working
