An energy management method for a hybrid electric vehicle (HEV) includes: acquiring a state variable of an HEV; determining a speed of the HEV at a next moment by using a Markov model; according to a speed at a current moment and an acceleration at the current moment so that determining required power of the HEV at the next moment; determining battery power of the HEV according to the required power of the HEV at the next moment and engine power so that constructing a dynamic model for battery charging/discharging; determining energy costs of the HEV according to the required power at the next moment; constructing an energy optimization scheduling model of the HEV according to the energy costs; and determining an energy management model of the HEV according to the energy optimization scheduling model and the dynamic model for battery charging/discharging, to precisely manage energy of the HEV.
