CHTC KINWIN (NANJING) AUTOMOBILE CO., LTD. has a perfect after-sales service system, which supports the satisfied performance of each vehicle.

Changes in vehicle performance in winter:

1. The usage of electric defroster, the switching on of battery self-heating and the switching on of air-conditioner heating will lead to a reduction in the vehicle's range or an increase in power consumption for the same mileage.

2. Low battery temperature will affect the dynamics of the whole vehicle, so the battery will automatically start the self-heating function. In the morning, the battery temperature is low, the vehicle electric retardation is weak, the driver brakes to slow down or stop, need to step on the brake pedal according to the needs of the appropriate deep, at the same time, the electric retardation is weak, resulting in a reduction of braking energy recovery and the battery self-heating consumes the battery's own power will cause the whole vehicle to increase energy consumption and reduce the driving range. As the battery self-heating is turned on, the battery temperature rises and the braking energy recovery returns to normal.

3. In order to better protect the battery and prolong its service life, when charging at low temperature, the allowable charging current of the battery becomes smaller, and part of the current is used for the battery self-heating, which leads to an extension of the overall charging time.

4. After the ambient temperature is lowered, the yellow indicator light showing AIRDRYER will often appear on the combination meter, and the legend text is [AIR DIYER], which is the indicator light of the dryer heating work. It is to heat the compressed air in the air circuit, which is a normal phenomenon.

Precautions for use:

1. After the ambient temperature is lowered, please install the movable sealing plate of the battery compartment door in time before traveling to insulate the battery and reduce the heat dissipation, avoiding the battery temperature drop significantly resulting in the prolongation of charging time and the increase of power consumption.

2. Charging operation: a. To improve the charging efficiency, please charge the battery in time after the vehicle is finished using. At this time, the temperature of the battery is suitable and the charging will be faster. Charging after the vehicle has been parked for a long time will cause the charging time to be prolonged. b. Place the charger indoors as much as possible, and when charging, check whether there is any condensation on the tip of the charging gun and whether it is dry to ensure safety.

3. When vehicle is traveling in rainy days, in order to ensure driving safety, please control the speed and keep a safe distance between the vehicle. Do not accelerate, decelerate or turn sharply.

4. To ensure the defroster effect, the electric defroster generally has higher electric power, and will consume more lithium battery energy when it works. So pure electric vehicles equipped with electric defroster should avoid turning on the electric defroster as a heating purpose when the temperature drops, and this operation will affect the driving range. The electric defroster with external air inlet should prevent the external air inlet filter from dumping mud or water, and needs to be checked regularly before driving to avoid blockage of the air inlet of the electric defroster, which may cause damage to the electric defroster.

5. According to the outdoor temperature, you need to determine whether the vehicle is stored in the garage or outdoors, so that the battery is kept in the appropriate temperature range.

6. If the vehicle needs to be stored for a long time, please keep the power SOC between 40%-70% before storing, and do the power battery equalization maintenance once every 3 months and before operation to improve the battery life.

7. In advance of entering the low-temperature areas, pure electric vehicles live in the morning since the next start before the need to preheat the power system, so that the viscosity of the steering fluid is reduced, the steering power to quickly return to normal. Preheating program: before starting the car must require electric steering work for a period of time, the specific length of time according to the actual situation, generally about 20 minutes, in the preheating process need to cooperate with the steering wheel.
