A method for remote preheating of pure electric vehicle battery

Abstract

A battery remote preheating method of a pure electric vehicle according to the present invention, the method is to send a battery remote preheating instruction to the T-BOX terminal of the automobile through a wireless communication module, and the T-BOX terminal judges whether it needs to be preheated according to the remote preheating instruction of the battery When preheating is required, the T‑BOX terminal controls the BMS to start working, and the BMS controls the car preheating module to preheat. Use a simple and feasible flow chart to control the realization of the remote preheating function of the battery of pure electric vehicles, avoid changing the hardware structure of the control unit BMS, PDU, and VCU of the original vehicle, and add a T-BOX terminal to realize the interaction with the intelligent network platform communication Function, the modification workload is small, and at the same time, it is compatible to realize the battery charging and heating functions, and the driving heating function, which effectively solves the technical problems of long battery cold start time and idling operation of pure electric vehicles at low temperatures in northern regions in winter.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and specifically relates to a remote preheating method for batteries of pure electric vehicles. Background technique [0002] A pure electric vehicle refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. The existing pure electric vehicle battery heating control generally adopts the method of charging with a gun or driving heating. By adding the control method of the remote preheating function of the battery parking, it can effectively solve the problem of long battery cold start time and vehicle idling at low temperatures in winter in northern regions. However, this method needs to pre-consider the reservation of the data receiving and sending control module T-BOX during vehicle design, as well as the reservation of hard-wired interfaces to wake up controller units such a...
