• 1. The speed of the vehicle cannot be increased, and the acceleration is weak;

Under low temperature, the battery activity decreases, the motor transmission efficiency decreases, and the vehicle power output is limited, so the vehicle speed cannot be increased.

• 2. No energy recovery function under special circumstances;

When the battery is fully charged or the battery temperature is lower than the allowable fast charging temperature, the recovered energy cannot be charged into the battery, so the vehicle will cancel the energy recovery function.

• 3. The heating temperature of air conditioner is unstable;

The heating power of different vehicles is different, and when the vehicle starts, all high-voltage electrical appliances of the vehicle are powered on successively, which will lead to unstable current of high-voltage circuit and cut off the heating air.

• 4. The brake is soft and slipping;

On the one hand, it originates from brake adjustment; On the other hand, due to the reduction of motor transmission efficiency in low temperature environment, the electronic control response of the vehicle slows down and the operation changes.

How to improve handling performance at low temperatures

• 1. Charge in a timely manner every day. It is recommended that the vehicle be charged after a journey. At this time, the battery temperature rises, which can improve the charging speed, improve the battery activity and ensure effective charging;

• 2. Start charging 1-2 hours before going out to adapt the “three electricity” to the ambient temperature and improve the low-temperature performance;

• 3. When the heating air of the air conditioner is not hot, it is recommended to adjust the temperature to the highest and the wind speed to gear 2 or 3 during heating; In order to avoid cutting off the warm air, it is recommended not to turn on the warm air at the same time when starting the vehicle, and turn on the warm air after 1 minute of starting until the battery current is stable.

• 4. Avoid frequent sudden braking, sharp turning and other random control habits. It is recommended to drive at a constant speed and step on the brake gently in advance to avoid excessive power consumption and affecting the service life of batteries and motors.

• 5. The vehicle shall be placed in a place with higher temperature to maintain battery activity.

• 6. AC slow charging is recommended.
