The invention relates to an electric vehicle heating mode energy-saving control method and a vehicle. The method comprises the steps that whether the vehicle has the heating requirement for an air conditioning system or not is judged; when the vehicle needs to heat the air conditioning system, whether the heat pump can operate or not is further judged; when the heating working condition of the heat pump is met, the heat pump operates; when the actual water temperature is smaller than or equal to the target water temperature minus 20 DEG C, the air conditioning system enters an overshoot heating stage; when the water temperature is larger than or equal to TWO + 10 or the PTC operation time is larger than or equal to 20 min, the air conditioning system enters a transition stage; when the water temperature is less than or equal to TWO + 0amp; when the PTC is smaller than or equal to 500 W or the water temperature is larger than or equal to TWO + 12, the air conditioning system enters a general heating stage; and when the water temperature is smaller than or equal to TWO-20, the air conditioning system returns to the overshoot heating stage. When the heat pump and the PTC need to work at the same time to meet the heating requirement, the heat pump is controlled to play the maximum capacity all the time, the PTC is controlled to work through the temperature, power and intervention conditions, the needed heating capacity is obtained with the minimum electric energy consumption, and the purpose of saving energy is achieved.

    本发明涉及一种电动车采暖模式节能控制方法及车辆,包括:判断车辆对空调系统是否有加热需求;当车辆对空调系统有加热需求时,进一步判断热泵是否可以运行;当符合热泵采暖工况时,热泵运行;当实际水温小于等于目标水温减20℃时,空调系统进入超调加热阶段;当水温≧TWO+10或PTC运行时间≧20min时,空调系统进入过渡阶段;当水温≦TWO+0&PTC≦500W或水温≧TWO+12时,空调系统进入一般加热阶段;水温≦TWO‑20时,空调系统回到超调加热阶段。本发明在需要热泵与PTC同时工作来满足采暖要求时,控制热泵始终发挥最大能力,通过温度、功率、介入条件控制PTC工作,以最少的电能消耗,获取所需制热量,达到节能的目的。
