There are more than 400 domestic complete vehicle enterprises, and the technical level of each complete vehicle factory is different from that of others. The new energy vehicles put on the market now also have frequent failures. So what are the main problems of new energy vehicles? How can we eliminate the source of these new energy vehicle faults when the whole vehicle is out of power and the charger is not charging,

1、 Introduction

With the popularization of new energy vehicles and the rapid development of technology, some failures will inevitably occur in their use. Understanding these common faults and their solutions is of great significance to users, maintenance personnel and even the whole industry of new energy vehicles. This article will introduce the common faults of new energy vehicles and their solutions in detail, New energy vehicle charging pile To help readers better understand and deal with these problems.

2、 Common faults of new energy vehicles

Battery system failure

Battery system is the core component of new energy vehicles, and its performance directly affects the operation of vehicles. Common battery system failures include low battery power, slow battery charging speed, high or low battery temperature, etc. These problems may cause the vehicle to fail to start, the driving distance to be shortened, and the charging to be interrupted.

Drive system fault

Drive system is the power source of new energy vehicles. Common drive system failures include motor failure, controller failure, transmission system failure, etc. These faults may lead to weak driving, increased noise, inability to accelerate, etc.

Charging system fault

Charging system is an important part of new energy vehicles, which is responsible for providing electric energy for batteries. Electric vehicle charging pile Common charging system faults include that the charging pile can not identify the vehicle, the charging speed is slow, and the charging is interrupted. These problems may cause the vehicle to fail to charge normally, thus affecting the use.

Air conditioning system fault

Air conditioning system is an important comfort configuration of new energy vehicles. Common air conditioning system failures include poor cooling effect, poor heating effect, fan failure, etc. These faults may affect the driving and riding experience of drivers and passengers.

Body system fault

Body system includes body structure, suspension system, braking system, etc. Common body system faults include abnormal sound of body, suspension system fault, braking system fault, etc. These faults may affect the stability and safety of the vehicle.

3、 Troubleshooting methods for new energy vehicles

Battery system fault handling

For battery system failure, first check whether the battery is sufficient, and if not, charge it in time. If the charging speed is slow, check whether the charging equipment is normal and whether the vehicle charging interface has foreign matters or damage. If the battery temperature is too high or too low, avoid using the vehicle for a long time in high or low temperature environment, and park the vehicle in a well ventilated place in time.

Drive system fault handling

For drive system failure, such as motor failure, check whether the motor has abnormal sound or overheating, and replace it in time if any. If the controller fails, try to restart the vehicle or check whether the controller connection line is normal. If the transmission system fails, check whether the transmission shaft, bearing and other components are damaged or loose, and replace or tighten them in time if any.

Troubleshooting of charging system

For charging system failure, if the charging point cannot identify the vehicle, check whether the vehicle charging interface is normal and whether the charging point supports the charging of the vehicle. If the charging speed is slow, check whether the power of the charging equipment matches the vehicle demand and whether the charging line is unblocked. If the charging is interrupted, check whether the charging equipment is faulty or the vehicle charging interface is loose.

Troubleshooting of air conditioning system

For air conditioning system failure, if the cooling effect is poor, check whether the air conditioning refrigerant is sufficient and whether the air conditioning filter element is clean. If the heating effect is poor, check whether the heating system works normally. If the fan fails, check whether the fan motor is damaged or the fan blades are loose.

Body system fault handling

For body system faults, such as abnormal sound of the body, check whether the body structure is loose or damaged. New energy vehicle maintenance If the suspension system fails, check whether the suspension spring, shock absorber and other components are damaged or aged. If the brake system fails, check the wear of the brake pads and whether the brake fluid is sufficient.

4、 Conclusion

The common faults of new energy vehicles and their treatment methods are diverse, covering many aspects such as battery system, drive system, charging system, air conditioning system and body system. Understanding and mastering these faults and their handling methods are of great significance to users, maintenance personnel and even the entire industry of new energy vehicles. Through the introduction of this article, we hope to help readers better understand and deal with the common problems of new energy vehicles.
