The invention relates to a remote preheating system for the battery of a pure electric vehicle. The system comprises a remote control module used for remotely controlling a vehicle to work, a wirelesscommunication module used for sending a remote preheating instruction of the remote control module, a vehicle control module used for controlling the working state of the vehicle, a remote control module for sending a control instruction through the wireless communication module to control the vehicle control module to conduct preheating. A simple and feasible flow chart is adopted to control the realization of the remote preheating function of the battery of the pure electric vehicle; hardware frameworks of a control unit BMS, a PDU and a VCU of an original vehicle are prevented from beingchanged; a T-BOX terminal is newly added to achieve the interaction function with the intelligent network connection platform, the modification workload is small; meanwhile, the functions of battery gun insertion charging heating and driving heating are achieved in a compatible mode, and the technical problems that the battery cold start time of the pure electric vehicle is long and the vehicle runs at an idle speed at the low temperature in the northern area in winter are effectively solved.
本发明的一种纯电动车电池远程预热系统,包括远程控制模块,用于远程控制车辆工作;无线通讯模块,用于发送远程控制模块的远程预热指令;汽车控制模块,用于控制汽车的工作状态;远程控制模块通过无线通讯模块发送控制指令控制汽车控制模块进行预热。本发明采用简易可行的流程图控制纯电动车电池远程预热功能的实现,避免原车的控制单元BMS、PDU、VCU改动硬件架构,并新增T‑BOX终端以实现与智能网联平台通讯的交互功能,改动工作量小,同时兼容实现电池插枪充电加热、行车加热功能,有效解决了纯电动汽车在冬季北方地区低温下电池冷启动时间长、车辆怠速运行技术问题。
