Summary:

With the increasing worldwide concern on environmental pollution, blade electrical vehicles (BEV) have attracted a lot attention. However, it still couldn't satisfy the market requirements because of the low battery power density, high cost and long charging time. The range-extended electrical vehicle (REEV) got more attention because it could avoid the mileage anxiety of the BEVs with lower cost and potentially higher efficiency. When internal combustion engine (ICE) works as the power source of range extender (RE) for REEV, its NVH, emissions in starting process need to be optimized. In this paper, a 2-cylinder PFI gasoline engine and a permanent magnet synchronous motor (PMSM) are coaxially connected. Meanwhile, batteries and load systems were equipped. The RE co-control system was developed based on Compact RIO, Labview and motor control unit (MCU). Focused on the starting process, the effects of first firing speeds, throttle control strategies and coolant temperatures were tested. The results show that the higher first firing speed is preferred without obvious torque fluctuation, and longer throttle switching duration to high load results in lower HC emissions. But the compromised duration for the engine in this paper is 5s
