Method for detecting illegal charging of battery car

Abstract

The invention relates to a method for detecting illegal charging of a battery car. The method comprises the steps: constructing one or more simulation scenes of illegal charging of the battery car, connecting a mutual inductor to a line corresponding to the simulation scene, collecting and analyzing the sample data of the mutual inductor, obtaining the power data in the simulation scene, obtaining the abnormal power utilization data based on the power data, and building a monitoring database; and setting a monitoring threshold value, connecting the mutual inductor to a real scene, collecting data of the mutual inductor, inputting a data flow into a monitoring database at a preset time interval, and if the data flow triggers the monitoring threshold value, indicating that the matching degree of the current data flow and abnormal power utilization data in the monitoring database is high, and disconnecting the connection. According to the invention, the access of the battery car can be accurately identified, the detection of illegal charging of the battery car in indoor, stairways, aisles and other scenes is solved, and a fire safety risk is reduced.

Description

technical field [0001] The invention relates to a circuit device or system for power supply or power distribution; the technical field of electric energy storage system, in particular to a method for detecting illegal charging of a battery car. Background technique [0002] A battery car, that is, an electric drive car, usually uses a battery / battery as an energy source, and converts electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. [0003] Battery cars have brought convenience to many people's travel, but accidents related to battery cars have occurred frequently in recent years. In addition to traffic accidents caused by improper operation of cyclists, battery car fire accidents have also occurred frequently, becoming the "hardest hit area" of fires , causing heavy losses to people's lives and property. [0004] The reasons for battery car fires include the following: [...

Problems solved by technology

[0007] (3) The battery of the old battery car swells after long-term charging, and its internal temperature may be as high as 100 degrees Celsius. The electrolyte is continuously evaporated due to high temperature, and then the copper wire is exposed after being heated, and the exposed positive and negative electrodes are in contact, short-circuited, and instantly caught fire;

[0008] (4) Due to the lack of short-circuit protection device, the circuit is short-circuited and causes a fire

[0009] With the increasing use of battery cars in the current market, fire accidents caused by battery cars should arouse people's attention. Due to the rapid fire speed and high temperature of batteries, special attention needs to be paid to the serious fire hazards in charging indoors and stairways.
