The invention discloses a charging strategy for prolonging the service life of a battery of a new energy automobile. The charging strategy specifically comprises the following steps that S1, a BMS sends the charging capacity of a charging pile; s2, a user selects a charging film type: A: a shortest charging time film type; b, a charging membrane type for prolonging the service life of the battery; c, customizing a charging time membrane form; s3, selecting an option A by a user, and running according to a normal charging strategy process; and S4, selecting the option B by the user, and selecting the charging power capable of prolonging the service life of the battery by combining the state of the battery. Three charging modes are designed, a user can select through a vehicle center console, an MP5 and a vehicle APP, the right of selection is given to the user, the user experience is improved, in addition, a new charging strategy design thought is provided, and compared with a normal design thought which mainly aims at improving the charging efficiency and shortening the charging time, the charging efficiency is greatly improved. The method is modified into a thought mode which mainly prolongs the service life of the battery and fully considers the acceptable charging time of a user.

    本发明公开了新能源汽车延长电池寿命的充电策略,具体包括以下步骤:步骤S1,BMS发送充电桩充电能力;步骤S2,用户选择充电膜式:A:最短充电时间膜式;B:延长电池寿命充电膜式;C:自定义充电时间膜式;步骤S3,用户选择A选项,按正常充电策略流程运行;步骤S4,用户选择B选项,结合电池状态,选择最能延长电池寿命的充电功率进行。本发明设计三种充电模式,用户可通过车辆中控台、MP5、车辆APP来进行选择,给予用户选择权,提高用户体验,另外本发明提供一种新的充电策略设计思路,较正常设计思路以提高充电效率及缩短充电时间为主相比,修改为以延长电池使用寿命并充分考虑用户可接受充电时间为主的思路方式。
