How to apply electronic diagnosis technology to the maintenance of new energy vehicles in China market?

In the traditional automobile engine maintenance, it is necessary to disassemble the automobile engine and check the engine parts. After adopting electronic diagnosis technology, the process of disassembling the engine is omitted, and the work intensity of automobile maintenance personnel and unnecessary losses of the engine are reduced. Electronic diagnosis technology can use electronic instruments to detect the data of different locations and infer the fault location according to the numerical changes, which greatly improves the maintenance efficiency of new energy vehicles.

The engine of new energy vehicle has no mechanical structure such as cylinder and piston, and its engine is mainly composed of battery and electronic control components. The structure between electronic components is very complex, which requires professional electronic instruments to detect, which is the main reason why electronic diagnosis technology is mainly used in the maintenance of new energy vehicles.

We use electronic diagnosis technology to detect the welding point of engine battery, and use electronic instruments to detect voltage, motor load, current stability, battery liquid consumption and so on. Professional auto mechanics can judge by the data detected by electronic instruments, and quickly find out the faults existing in the engine of new energy vehicles.

When using electronic diagnosis technology to detect the hybrid engine, it is necessary to detect professional data such as oil hydraulic value, engine power output parameters, ignition device sensitivity, etc., so as to find engine faults according to the detected data and improve the efficiency and quality of engine maintenance.

The power system and control system of new energy vehicles are mainly controlled by circuits, such as battery power supply system, intelligent cooling system and vehicle lock system. Circuit failure will directly affect the operation of new energy vehicle parts. Circuit faults in the circuit system of new energy vehicles are common, such as excessive circuit load, circuit temperature, battery internal solution and so on. , it will affect the speed and driving safety of the vehicle.

We can use electronic diagnosis technology to test the circuits of new energy vehicles. Auto repair workers can connect the fault detector to the circuit system and observe whether the warning light of the circuit flashes. If it flashes, it proves that there are faults such as leakage and virtual electricity in the circuit. Multimeter is also a common equipment in electronic diagnosis technology. Maintenance personnel can insert the multimeter into the circuit of the new energy vehicle, observe the change of the multimeter pointer, and observe whether the voltage value fluctuates greatly and whether the voltage value is within the normal range.

According to the instrument value, the circuit fault can be calculated quickly, which can save the maintenance time, minimize the damage of the circuit to the new energy vehicle and prolong the service life of the battery and electronic components of the new energy vehicle.
