Abstract:

An extended-range electric vehicle model with a compressed natural gas （CNG） engine was established referring to the experimental test data of the CNG engine. A rule‐based method for power split was proposed to ensure that the CNG engine works in the high-efficiency area. However， its current fluctuates greatly， which will result in a damaged battery. In order to suppress the current surge and further improve fuel consumption， a model predictive control （MPC） method for power split coordinating fuel consumption and battery protection was proposed. Simulation results show that the proposed MPC method can further reduce fuel consumption by 3.7% and suppress the current surge for effectively protecting the battery， as compared to the rule‐based method under a world light test cycle （WLTC） driving cycle.

Key words: automatic control technology, model predictive control, energy management, extended-range electric vehicle, compressed natural gas engine
