Does a pure electric vehicle have an engine?

Pure electric vehicles have no engines, only motors. Working principle of pure electric vehicle: Electric vehicle drives the vehicle to complete the work through battery current, power regulator and motor power transmission system.

A motor is a device that converts electric energy provided by a power supply into mechanical energy. The power supply provides electric energy for the motor, which is the driving mechanism of the electric vehicle. The motor converts the electric energy of the power supply into mechanical energy, and directly drives the wheels and working devices through the transmission device.

Lead-acid batteries are widely used in electric vehicles, but with the development of electric vehicle technology, lead-acid batteries are gradually replaced by other batteries because of their low energy, slow charging speed and short life.

There are many electronic systems in pure electric vehicles, and the reliability of electronic systems is not as good as that of pure machinery, so regular inspection is also very important. In order to check the circuit system, you can usually go to the 4S shop and ask the maintenance personnel to plug in a special computer for testing.

In addition to using the computer, you should also check the wiring and plugs to eliminate potential safety hazards and avoid short circuit and leakage. Chassis part, check whether the battery pack is damaged, whether chassis parts are deformed, whether bolts are loose, oil leakage, etc. Million car purchase subsidy
