[0003] The invention patent with the application number of 201010248589.9 discloses an electric vehicle anti-theft system. The system implements the electric vehicle anti-theft through the method of alarm, remote control and ID user, but this system cannot solve the situation that the main power supply is cut off. Cut off the main power line and then remove the alarm device, then reconnect the main power line to achieve the theft of electric vehicles, so it is necessary to invent a method to prevent power cut

Embodiment Construction
[0023] An anti-theft system for an electric vehicle with an anti-shearing power cord, comprising a main circuit and an auxiliary circuit on the electric vehicle, and a wheel brake device. The main circuit has a current detection device, an electromagnetic device and an alarm, and the auxiliary circuit includes Independent power supply, electromagnetic device, spring components, GPS locator and alarm;
[0024] It is characterized in that, the electric vehicle anti-theft system judges whether the main circuit is cut off by the change of the electromagnetic coil and the change of the current;
[0025] The current detection module is used to detect changes in current on the main circuit;
[0026] The electromagnetic coil of the electric vehicle anti-theft system judges whether the main power supply is operating normally. When the system is started, the main power supply loses power and the electromagnetic coil loses power to start the auxiliary circuit. When the main power supply restart...

The invention discloses an anti-theft system with an anti-shearing power cord of an electric vehicle. The anti-theft system with the anti-shearing power cord of the electric vehicle comprises a main circuit, an auxiliary circuit and a wheel braking device which are arranged at the electric vehicle, wherein the main circuit is provided with a current detection module and an electromagnetic coil alarm; and the auxiliary circuit comprises an independent power supply, electromagnetic coils, a spring component, a GPS device and an alarm. The power failure of the main circuit causes the power failure of the electromagnetic coils to activate the auxiliary circuit. When the main circuit is restarted, a processor activates the alarm or the GPS device on the auxiliary circuit when a current value is greater than a preset threshold according to the variation of the current so as to prevent the power cord from being rewired after the main power cord is cut off and the alarm is removed and improve the anti-theft factor of the electric vehicle.
Description
Technical field [0001] The invention relates to an anti-theft system, in particular to an electric vehicle anti-theft system. Background technique [0002] At present, the anti-theft systems of electric vehicles mostly use sound, vibration, remote control, GPS positioning and other anti-theft methods to prevent theft. However, these anti-theft methods for electric vehicles also have a defect in preventing theft; [0003] The invention patent with application number 201010248589.9 discloses an electric vehicle anti-theft system. This system uses an alarm, remote control and ID user method to carry out electric vehicle anti-theft, but the system cannot solve the situation that the main power supply is cut off. Cut off the main power cord and then remove the alarm device, and reconnect the main power cord to achieve the theft of the electric vehicle, so it is very necessary to invent a method to prevent the power supply from being cut. Summary of the invention [0004] The purpose of ...
