Why does the BAIC EX3 lose power quickly?

[DelJonathan]

BAIC EX3 may lose power quickly due to incorrect battery charging time and frequency, improper driving, winter characteristics, etc. The following are the reasons: Incorrect battery charging time and frequency: Under normal driving conditions, if both the red and yellow lights of the battery gauge are on, charging should be performed; if the yellow light goes out and only the red light remains on, operation should be stopped and charging should be performed as soon as possible. Otherwise, the battery life will be shortened due to over-discharge. Some people are accustomed to charging before each trip, sometimes recharging after only a short period of operation. In this case, the charging time should not be too long, otherwise overcharging will occur, causing the battery to overheat. Improper driving: When starting, carrying passengers, or going uphill, if the accelerator is pressed hard, it will cause instantaneous high-current discharge. High-current discharge can easily lead to a short circuit, and the battery may burn out or even explode. If the speed suddenly drops significantly during driving, be careful as it may indicate a problem with a certain group of batteries, and they should be checked as soon as possible. Winter characteristics: As the temperature gradually drops below freezing, the driving energy consumption of electric vehicles in winter continues to rise, directly leading to very rapid power loss. A set of data previously released by the China Automotive Research Institute showed that when the outdoor temperature is -7 degrees Celsius and the indoor temperature is 22 degrees Celsius, the average range of pure electric vehicles will drop by as much as 39 percent. For mini electric vehicles without a battery temperature control system, the power loss can be as high as 60 percent.

Having driven the BAIC EX3 for over two years, I believe the rapid battery drain is mainly due to driving habits. For instance, my usual habits of sudden acceleration and hard braking consume a lot of power, especially noticeable on highways where the range drops significantly. Also, setting the air conditioning too high, especially the heater in winter, worsens the situation. I found simple ways to optimize: drive smoothly, use ECO mode more often, and reduce high-speed aggressive driving; preheat the air conditioning while plugged into the charger; and regularly check tire pressure, as low pressure increases resistance. Additionally, onboard electronics like the stereo or phone charging also quietly drain the battery—turn them off when possible. In short, after adjusting driving and power usage habits, the range has improved considerably. I recommend owners pay more attention to daily operations rather than just complaining about the hardware.

As an EV enthusiast with some knowledge, I've found that the rapid battery drain in EX3 often stems from battery issues. Performance degradation due to aging is the primary cause, especially noticeable capacity reduction after prolonged use. Charging habits are also crucial – frequent fast charging or deep discharges can cause excessive wear. Software bugs sometimes play a role too; after one firmware update, I noticed some improvement. I recommend regular battery health diagnostics, maintaining charge between 20%-80%, and avoiding frequent deep cycles. Environmental factors matter too – hot weather reduces battery efficiency, so I always charge in shaded areas. With these maintenance practices, you can effectively extend range and reduce range anxiety.

I own an EX3 and noticed that the battery drains fastest during winter commutes, as low temperatures reduce battery discharge efficiency. Using the heater and defogger consumes a lot of power, dropping the remaining range significantly within minutes. In summer, the air conditioning has a similar impact. What I've learned: charge during warmer periods, like in a heated garage; preheat the vehicle to reduce power consumption. On the road, use regenerative braking to recover energy, which helps save power in city traffic jams. After making these simple habit changes, the range stability has improved.
