The invention discloses a battery preheating method and system. The method comprises the following steps: setting departure time tSet; calculating energy EReq required for heating the battery pack to a target temperature; calculating the time tReq required for heating the battery pack to the target temperature; and determining whether to heat the battery pack or not according to the departure time tSet, the energy EReq required for heating the battery pack to the target temperature and the time tReq required for heating the battery pack to the target temperature. According to the invention, after the user sets the starting time, the heating time of the battery and the required heating energy are automatically predicted and calculated, and the battery is heated at a proper time, so that the battery is approximately just heated to a proper temperature before the starting time; the problems that the energy of the battery is continuously consumed if battery heat preservation is selected and the temperature of the battery is continuously reduced if heat preservation is not carried out and the battery cannot be kept at a proper temperature during starting are solved.
本发明公开了一种电池预热方法及系统。该方法包括设定出发时间t_Set;计算把电池包加热到目标温度所需的能量E_Req;计算把电池包加热到目标温度所需的时间t_Req;根据出发时间t_Set、把电池包加热到目标温度所需的能量E_Req以及把电池包加热到目标温度所需的时间t_Req,确定是否对电池包进行加热。本发明在用户设定出发时间后,自动预测计算电池加热的时间和需要的加热能量,在合适的时候开始对电池加热,以在出发时间之前大致刚好把电池温度加热到适宜的温度,避免了如果选择电池保温继续消耗电池的能量以及如果不保温则电池温度会继续下降无法在出发时保持电池在适宜的温度的问题。
