A wireless charging control method for electric vehicles based on lora network

Abstract

The invention discloses a LoRa network-based electric vehicle wireless charging control method in the technical field of electric vehicle charging, including an electric vehicle, a charging device, a server and a LoRa base station, and the electric vehicle, the charging device and the server are all connected to the LoRa base station to establish On the LoRa network, the electric vehicle and the charging device are controlled by the server through the LoRa network. Charging does not require personnel to supervise at all times. The electric vehicle can automatically work and charge under the control of the server, and has the ability to calibrate the charging position multiple times. Steps to ensure that the charging position is accurate, so it has greatly improved the situation of false alarms that often occur in existing charging equipment due to inaccurate charging positions, so that as long as there is an alarm, it is generally a real fault of the device, and through wireless charging, charging The scope is wider, and the system can directly receive the alarm from the server through the terminal to remind the staff to carry out maintenance.

Description

technical field [0001] The present invention relates to the technical field of electric vehicle charging, in particular to a LoRa network-based wireless charging control method for electric vehicles, Background technique [0002] The unmanned vans used in logistics are all electric vehicles. These electric vehicles need to be charged. At present, the AGV trolley is widely used. The purpose of this unmanned van is to save manpower and improve handling efficiency. However, The charging procedure is more difficult to control; [0003] At present, there are three ways to charge unmanned vans, some of which are manual charging, battery charging and automatic charging; [0004] Manual charging: When the power of the unmanned guided vehicle is insufficient, the ground control center is directed to the designated charging area or platform, and the electrical connection between the unmanned guided vehicle and the charger is manually completed by full-time personnel, and then the cha...

Problems solved by technology

[0007] However, the current automatic charging method is difficult to calibrate the charging position, and it is difficult for the system to match a suitable unmanned van and charging device, resulting in the system may not be able to operate perfectly and reasonably, and it is difficult for the unmanned van to be completely accurate when charging. Accurate charging ports lead to charging errors, which makes charging unsuccessful, and maintenance personnel are often required to correct charging equipment and unmanned vans, which greatly reduces the efficiency of automatic charging, making automatic charging also require constant maintenance. Now There is a need for a charging with higher accuracy, which can repeatedly confirm the charging position, avoid alarms due to abnormal charging due to inaccurate positioning, avoid repeated maintenance due to inaccurate encirclement, reduce the number of personnel monitoring, and arrange charging sequences Reasonable charge control method
