CHARGING CONTROL METHOD AND SYSTEM FOR RANGE EXTEND ELECTRIC VEHICLE, AND ELECTRIC VEHICLE
CHARGING CONTROL METHOD AND SYSTEM FOR RANGE EXTEND ELECTRIC VEHICLE, AND ELECTRIC VEHICLE
Disclosed are a charging control method and system for a range extend electric vehicle, and the electric vehicle. The control method includes: presetting a first threshold value and a second threshold value and executing the following steps: when the electric quantity of a battery is lower than the second threshold value, performing forced charging on the battery; when the electric quantity of the battery is lower than the first threshold value and higher than the second threshold value, proceeding to a subsequent step to determine whether Pv+Pb1>Pu is met, Pv, Pb1 and Pu respectively representing current vehicle driving required power, minimum required charging power of the battery and maximum power of a high efficiency running range of an engine; if not, determining the time as an optimal charging time, controlling the engine to increase the power to Pu, and charging the battery with a power of Pu−Pv; and if so, skipping performing charging, and predicting an optimal charging time for charging according to a terrain condition or road environment ahead. On the basis of the above charging control method, the optimal charging time of the range extend electric vehicle can be predicted, ensuring that the engine runs in a high efficiency power range while charging the battery, and achieving better economic efficiency.
