Load limiting system for electric vehicle

Abstract

The invention provides a load limiting system for an electric vehicle. By the adoption of the load limiting system for the electric vehicle, the problems that in the prior art, due to the overload of an electric vehicle, the vehicle is damaged, and even traffic accidents are caused are solved. The load limiting system for the electric vehicle is composed of a pressure sensor, a single-chip microcomputer, a relay, a buzzer and an LED nixie tube. The load limiting system for the electric vehicle is characterized in that the pressure sensor is arranged below a cushion of the electric vehicle and connected with the single-chip microcomputer and can detect the load of the electric vehicle; the relay is controlled by the single-chip microcomputer and connected with an electric vehicle starting circuit and can control the on-off of the electric vehicle starting circuit; the LED nixie tube is arranged on the interface of an electric vehicle odometer and can display the load condition of the electric vehicle; and when the load of the electric vehicle exceeds a rated load, the single-chip microcomputer sends a command to the relay, the relay cuts off the electric vehicle starting circuit after receiving the command, the electric vehicle cannot be started, and the buzzer gives an alarm at the moment to remind a driver of the overload. The load limiting system for the electric vehicle is simple in design, convenient to use, low in cost and easy to popularize.
