The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle quick charging method based on battery preheating and a control system. The quick charging method mainly comprises the steps of S1, detecting whether a user inputs a battery preheating control instruction or not, if yes, executing the next step, and if not, continuously detecting,S2, judging whether the current real-time temperature of the battery exceeds the optimal charging temperature range or not, and if so, executing the next step,and S3, judging whether the current residual electric quantity of the battery meets the preheating electric quantity required by the battery or not, and if so, directly heating the battery to the optimal charging temperature range. The problems that in an existing battery preheating technology, the electric quantity of a charging pile is adopted for preheating, the charging time is prolonged, and the charging efficiency is reduced are solved, and if the electric quantity of a battery is adopted for preheating the battery, energy consumption occurs, and the intention of a driver is violated are solved.

    本发明涉及电动汽车充电技术领域,特别涉及一种基于电池预热的电动汽车快速充电方法及控制系统,快速充电方法主要包括步骤:S1,检测用户是否输入电池预热控制指令,若是则执行下一步,若否则持续检测;S2,判断当前电池的实时温度是否超出最佳充电温度范围,若是则执行下一步;S3,判断当前所述电池的剩余电量是否满足所述电池所需的预热电量,若满足则直接加热所述电池直至所述最佳充电温度范围。本发明的提出解决了现有电池预热技术中采用充电桩的电量进行预热,会拉长充电时间,降低充电效率的问题,以及若采用电池自身电量预热电池,则会出现能源耗费,且违背驾驶员意志的问题。
