The invention discloses an electric door lock communication line front passive detection multifunctional protection device system, associated electric appliance parts and an electric vehicle. The system comprises an adapter, a protection device, a large wire, a front electric appliance and an electric door lock. And the protection device is connected with the adapter through the large wire. The protection device comprises a main loop control circuit, and a main loop power supply is switched on and off through the loop control circuit. The electric door lock is connected with a communication line and a ground wire, the electric door lock adopts a negative logic switch mechanism of a normally-closed switch, and the electric door lock is in a disconnected state when the electric door is opened and is in a connected state when the electric door is closed. When the electric vehicle is shut down, the protection device closes the working power supply of the adapter through the whole vehicle electric appliance electronic safety circuit and the power line, the mcu circuit m sets the communication line pin to be in a GPIOin or ADCin mode, and the opening and closing state of the electric door lock is judged by detecting the voltage of the pin. And when the voltage is higher than the rated value, the vehicle is mainly started. A special chip wide-voltage zero-static-power-consumption converter circuit, a handlebar lock circuit, a seat cask lock circuit, a buzzer booster circuit, a BMS communication circuit, a charger output voltage control circuit and a built-in charger circuit are additionally arranged, and the application height of the product is increased.
