The invention relates to the technical field of vehicles, in particular to a low-electric-quantity static fuel oil charging method for a new energy vehicle. Due to the requirement for the small opening of the appearance design of the front end of an automobile, intercoolers of some automobile types are cooled by natural inlet air, when the automobile of the type is charged under the static working condition, the actual heat dissipation capacity of the intercoolers is obtained by detecting the environment temperature firstly, and the actual heat dissipation capacity is compared with the static theoretical heat dissipation capacity of the intercoolers; judging whether turbocharging intervenes in fuel charging or not; and then, according to the calculated recharging power of the range extender, the final recharging rotating speed of the engine is calculated, so that recharging is completed within the shortest time and with the highest charging efficiency, and the use experience of a user is improved. Besides, in order to improve the charging efficiency, the temperature of the battery is firstly reduced, so that the temperature of the battery is at the temperature value of the optimal charging efficiency, and compared with the prior art, the charging efficiency can be greatly improved, and the charging time is shortened.

    本发明涉及车辆技术领域,更具体地,涉及一种新能源汽车低电量静态燃油补电方法;由于汽车前端外观设计小开口化的需求,某些车型的中冷器依靠自然进风冷却,该类型车辆在静态工况下进行补电时,首先通过检测环境温度,进而得到中冷器的实际散热能力,并于中冷器静态理论散热能力比较,判断涡轮增压是否介入燃油补电;然后根据计算得到的增程器补电功率计算得到最终发动机补电转速,从而以最短的时间,最高的充电效率完成补电,提升用户的使用体验;另外,本发明为了提高补电效率,首先对电池温度降温,使电池温度处于最优充电效率所处的温度值,相较于现有技术,可极大提高补电的效率,减少补电时间。
