What are the reasons why BAIC New Energy vehicles fail to start?

It is an issue with the vehicle's battery. Below is relevant information: For conventional vehicles: If a conventional vehicle fails to start during normal use, the vehicle's battery needs to be inspected. The normal service life of a vehicle battery ranges from 1 to 8 years, depending on the vehicle's usage. Proper maintenance of the vehicle battery can help extend its lifespan. For new energy vehicles: The battery is the primary power source for new energy vehicles. If the battery is depleted or damaged, the vehicle will fail to start and cannot be driven. During the use of new energy vehicles, it is essential to protect the battery, and a pre-heating system can be installed to help.

There are quite a few reasons why a BAIC New Energy vehicle might not start. From what I've observed, the power battery is often the main culprit. The lithium batteries used in these cars are sensitive to temperature. If it's too cold in winter, the battery's activity decreases, and the system won't start. Additionally, if the battery is completely drained and not recharged, or if the battery is aging and causing voltage instability, the high-voltage relay will trip for protection. Also, issues with the charging port connection or faults in the management module can lead to startup failure. It's recommended to first check the battery status. If the display shows no response, try slow charging for an hour or two to see if it can be reactivated. If that doesn't work, it's best to contact professional repair services. After all, new energy vehicles rely on electric power, so forcing it might damage the car. Developing a habit of regular charging can help prevent this issue.

When the car won't start, don't immediately worry about major issues—it's likely just a problem with the 12V auxiliary battery. This little component is responsible for controlling the high-voltage system startup. If it's dead, the entire vehicle will be paralyzed. Common causes include forgetting to turn off electrical devices after locking the car, such as leaving lights or the music system on, which drains the battery. Alternatively, the battery may be aging and need replacement after less than two years. From my own experience, if the dashboard doesn't light up when you get in the car, it's usually due to a drained auxiliary battery. A quick fix is to jump-start it using jumper cables connected to another vehicle—wait a minute or two before attempting to start. To prevent this, avoid leaving the car parked for too long without use, especially in cold weather, as it can shorten the auxiliary battery's lifespan. If the issue persists, it's best to have the dealership check the wiring and charging ports.

This issue might be related to the charging system. If the car isn't charging, it naturally won't start. Common causes include a malfunctioning home charging station with no output current, or a faulty onboard charger failing to recognize the power source. There could also be poor contact in the high-voltage wiring, leading to charging interruption. My suggestion is to check if the charging indicator light is on. If charging fails, try switching to a different socket or charging station. While new energy vehicles save fuel, they rely on charging infrastructure, making it essential to clean dust and inspect cable connections during maintenance. Promptly identifying and fixing charging problems can prevent embarrassing situations like failure to start, and it's also more environmentally friendly.

Control circuit failure is a common root cause. Both the large and small batteries are functioning normally, but a blown high-voltage fuse or a stuck relay can prevent the system from starting. There are also false alarms from the ECU module, such as when a sensor fails to detect the key signal or locks due to voltage imbalance. From my experience, using a diagnostic tool to read error codes is highly effective. If it shows a BMS system alarm, it's most likely a relay issue. Avoid repairing high-voltage components yourself, as there's a risk of electric shock. It's best to turn off the engine, wait a few minutes, and then try restarting to prevent overheating from continuous operation. Remember, the structure of BAIC New Energy vehicles is a bit more complex, and regular maintenance can reduce such issues.

User operation errors can sometimes prevent the engine from starting, such as pressing the start button without shifting to P gear, where the system prevents startup for protection. Or when the key battery is dead and cannot unlock, failing to detect the signal. Also, if the vehicle is not completely powered off when parked, it may enter sleep mode and be difficult to wake up. Personally, I make it a habit to check the dashboard information before starting, looking for any error messages. If there are no major issues, turning off the engine and locking the car for a few minutes before trying again usually resolves the problem. With new energy vehicles, extra care in operation is needed to avoid minor mistakes leading to major malfunctions.
