The invention discloses a remaining charging time determination method and device and a vehicle, and belongs to the technical field of vehicles. Comprising the steps that first voltage and second voltage are determined based on the battery type, the current electric quantity and the target electric quantity of a power battery of a target vehicle, the target electric quantity is the cut-off electric quantity of charging, the first voltage refers to the total voltage of the power battery when charging starts, and the second voltage refers to the total voltage of the power battery when charging ends; based on the first voltage, the second voltage and target power, the average current in the process from charging starting to charging ending is determined, and the target power is the output power of a charging pile for charging the target vehicle; and determining the residual charging time of the power battery based on the average current, the current electric quantity, the target electric quantity and the total capacity of the power battery. According to the method, the residual charging time is calculated according to the average current in the whole charging process, and compared with the maximum output current, the relatively accurate residual charging time can be determined, so that the user experience is improved.

    本申请公开了一种剩余充电时间确定方法、装置和车辆,属于车辆技术领域。包括:基于目标车辆的动力电池的电池类型、当前电量以及目标电量,确定第一电压和第二电压,目标电量为充电的截止电量,第一电压是指开始充电时动力电池的总电压,第二电压是指结束充电时动力电池的总电压;基于第一电压、第二电压以及目标功率,确定开始充电至结束充电过程中的平均电流,目标功率为向目标车辆充电的充电桩的输出功率;基于平均电流、当前电量、目标电量以及动力电池的总容量,确定动力电池的剩余充电时间。本申请通过依据整个充电过程中的平均电流来计算剩余充电时间,相对于最大输出电流来说,可以确定出较为准确的剩余充电时间,进而提升用户体验。
