The invention discloses an electric vehicle charging remaining time estimation method. The method comprises the steps: employing a double-time T calculation method, and displaying charging remaining time T display and the real charging remaining time T true, wherein the displayed charging remaining time T display is mainly the charging remaining time reported by a system, the real charging remaining time T true is estimated according to a charging remaining time strategy, and a T display change dynamically adjusts a T display descending rate according to a T true change. According to the scheme, the double-time T calculation method is used; and the real charging remaining time and the display charging remaining time are divided, a problem that the charging time fluctuates is effectively solved, meanwhile, the charging remaining charging time and the heating time of the battery are dynamically estimated in real time, a charging remaining time rate is dynamically adjusted and displayed in real time, more visual perception is brought to consumers, and a charging remaining time precision problem is also solved.
本发明公开了一种电动汽车充电剩余时间估算方法,使用双时间T计算方法,分显示充电剩余时间T显和真实充电剩余时间T真;显示充电剩余时间T显主要是系统上报的充电充电剩余时间,真实充电剩余时间T真按充电剩余时间策略估算得出,T显变化根据T真变化做动态调整T显下降速率;本方案,使用双时间T计算方法,分真实充电剩余时间和显示充电剩余时间,有效错开充电时间忽大忽小问题,同时实时动态预估电池充电剩余充电时间和加热时间,实时动态调整显示充电剩余时间速率,给消费者更加直观的视觉感受,也解决了充电剩余时间精度问题。
