The invention discloses a new energy vehicle, a power supply device and a control method thereof, and the control method comprises the steps: obtaining the related information of the vehicle, predicting the power demand of a low-voltage power module of the vehicle according to the related information, and enabling the related information to comprise vehicle state information and environment information; and the charging state of a starting battery of the vehicle is adjusted according to the power utilization requirement of the low-voltage power utilization module, so that the starting battery meets the power utilization requirement of the low-voltage power utilization module. According to the technical scheme, the charge-discharge state of the starting battery is dynamically adjusted, the service life of the starting battery is prevented from being attenuated due to too high charge capacity or deep discharge, and the vehicle use and maintenance cost is effectively reduced.

    本发明公开一种新能源车辆、供电装置及其控制方法,控制方法包括:获取车辆的相关信息,根据相关信息预测车辆的低压用电模块的用电需求,相关信息包括车辆状态信息和环境信息;根据低压用电模块的用电需求调节车辆的启动电池的充电状态,以使启动电池满足低压用电模块的用电需求。本技术方案动态调节启动电池的充放电状态,避免启动电池由于充电电量过高或者深度放电导致启动电池寿命衰减,有效降低车辆使用和维护成本。
