Embodiment 1

[0038] Refer to attached figure 1 , a remote preheating system for a pure electric vehicle battery in this embodiment, comprising

[0039] The remote control module 100 is used for remotely controlling the work of the vehicle;

[0040] The wireless communication module 200 is used to send the remote preheating instruction of the remote control module 100;

[0041] The vehicle control module 300 is used to control the working state of the vehicle;

[0042] The remote control module 100 sends a control command through the wireless communication module 200 to control the vehicle control module 300 to preheat.

[0043] 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 original vehicle's control unit BMS, PDU, and VCU, and add a T-BOX terminal to realize the interaction with the intelligent network platform communication Function, the modificatio...

Embodiment 2

[0060] An operation method for a remote battery preheating system of a pure electric vehicle. The remote control module 100 sends a control command through the wireless communication module 200 to control the vehicle control module 300 to perform preheating. The controller 310 of the vehicle control module 300 receives the wireless communication module 200 The remote preheating command is distributed to the battery management unit 320 and the detection unit 330. After receiving the remote preheating command from the controller 310, the detection unit 330 detects the battery status to determine whether there is a heating demand and feeds back data to the The controller 310, when preheating is required, the controller 310 sends a preheating instruction to the battery management unit 320, and the battery management unit 320 controls and drives the total negative contactor, the battery heating positive contactor, and the battery heating negative contactor to work for preheating ; W...

Embodiment 3

[0063] A vehicle with a remote battery preheating system for pure electric vehicles includes the remote battery preheating system for pure electric vehicles described above.

Abstract

A remote preheating system for a pure electric vehicle battery of the present invention includes a remote control module for remotely controlling the operation of the vehicle; a wireless communication module for sending remote preheating instructions from the remote control module; a vehicle control module for controlling the vehicle working status; the remote control module sends control commands through the wireless communication module to control the vehicle control module to preheat. The invention adopts a simple and feasible flow chart to control the realization of the remote preheating function of the pure electric vehicle battery, avoids changing the hardware structure of the control unit BMS, PDU, and VCU of the original vehicle, and adds a T-BOX terminal to realize communication with the intelligent network platform The interactive function, the modification workload is small, and at the same time, it is compatible with the battery gun charging heating and driving heating functions, which effectively solves the technical problems of long battery cold start time and vehicle idling operation of pure electric vehicles in winter at low temperatures in northern regions.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to a remote preheating system 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 as BMS, PDU,...
