Embodiment Construction

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with embodiments.

[0028] The present invention provides an electric vehicle with a safety circuit structure, including a circuit safety module and an alarm module. The circuit safety module is connected to the circuit of the electric vehicle to detect whether the circuit is safe, thereby avoiding the occurrence of fire , the circuit security module is connected to the alarm module,

[0029] The safety detection of the circuit safety module includes the following steps:

[0030] 1) Collect the current value of one cycle of household 220V / 50Hz alternating current with a sampling frequency of 3200Hz, and obtain 64 discrete current values, which are denoted as I 0 , I 1 ,..., I 63 , to form the current waveform data set of this cycle;

[0031] 2) By comparing the current value ...

Abstract

The invention discloses an electric vehicle with a safe circuit structure. Compared with the prior art, by arranging a security module in a vehicle circuit, detection is conducted through the security module; when something dangerous happens, the security module sends a signal to an alarm module which gives an alarm, and a driver knows danger in time and disposes the dangerous situation in time.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an electric vehicle with a safety circuit structure. Background technique [0002] An electric vehicle (EV) 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. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic, but the current technology is still immature. Its working principle is: battery - current - power regulator - electric motor - power transmission system - driving the car. [0003] Electric vehicles in the prior art use electric power as the power of the vehicle, so protection against circuit faults is an important research topic. Contents of the invention [0004] The object of the present invention is to provide an electric vehicle with a safety circuit structure to solve the above-mentio...
