The invention discloses an intelligent charging method for a storage battery of a new energy electric vehicle, which comprises the following steps that when a BMS has no fault, an internal network continuously runs and monitors the voltage of the storage battery in real time, when the voltage of the storage battery is lower than a set threshold value, it is judged that charging is needed, the BMS sends an intelligent charging request to a VCU, and the VCU controls the whole vehicle to be powered on and then charges the storage battery. The method has the advantages that the BMS is adopted to monitor the voltage of the storage battery in real time, the used hardware is vehicle-mounted hardware, the hardware cost is not increased, and the BMS works in an intranet environment, is low in power consumption and is safe and reliable; the BMS can monitor the voltage of the storage battery in real time and can automatically charge the storage battery, so that the reliability of the electric quantity of the storage battery is ensured; if the BMS breaks down and cannot automatically monitor the voltage of the storage battery, a reminding signal is forwarded to a mobile phone terminal of a vehicle owner through the TSP, and the purpose of real-time reminding is achieved.
本发明公开了一种新能源电动汽车蓄电池智能补电的方法,BMS无故障时内网持续运行并实时监控蓄电池的电压,当蓄电池电压低于设定阈值时,则判断需要补电,BMS发出智能补电请求至VCU中,由VCU控制整车上电后为蓄电池补电。本发明的优点在于:采用BMS实时监控蓄电池电压,利用的硬件均为车载硬件,没有增加硬件成本,BMS工作在内网环境,功耗低且安全可靠;BMS可以实时监控蓄电池电压并可以自动对蓄电池补电,保证了蓄电池的电量可靠;BMS若出现故障无法实现自动监控蓄电池电压,则会通过TSP转发提醒信号至车主手机终端,做到实时提醒的目的。
