"Why is the car's battery life shortened?"

"Why is the charging speed so slow?"

Don't worry! Today, I have compiled a winter charging guide for everyone, so that your car can remain "healthy" and drive safely in the cold winter. Strongly recommended to collect!

 

1 Check the battery performance

The battery of a new energy vehicle is a core component, and the health of the battery directly affects the performance and safety of the vehicle. After entering winter, you need to check the battery power, whether the battery pack is firmly connected, whether the battery life is shortened, etc., to understand the battery usage status to ensure performance and battery life.

 

2 Extend the charging time

In winter, the battery of new energy vehicles has poor charging acceptance, and it is easy to be fully charged and insufficient power. It is necessary to appropriately extend the daily charging time. The charging time in winter may be slightly longer than in other seasons. Don't rush to unplug the charger and make sure the battery is fully charged. Generally speaking, slow charging is more beneficial to battery maintenance. When planning a car trip, car owners need to fully consider the decline in vehicle mileage to avoid affecting travel.

3 Appropriate charging temperature

The suitable charging environment temperature range for new energy vehicles is 0℃ to 45℃. In winter, you should try to avoid charging the car in an environment below 0℃. If the temperature is low, car owners can try to choose indoor parking lots or sheltered charging stations and other relatively warm environments to charge, or choose to charge in the afternoon when the temperature is slightly higher. Charge as you use to avoid low battery power. For vehicles parked in the open air, start at least twice a week, and each run time is more than 20 minutes.

4 Keep the charging plug clean and dry

In winter, the temperature is low, and frost will turn into water, which may penetrate into the plug and affect the battery of the vehicle. When car owners use public charging stations in public parking lots, they should first check whether the charging plug is clean and dry.

 

5 Warm up the car before driving

The temperature in northern regions is often below 0℃ in winter, and vehicles are parked for a long time at low temperatures. It is necessary to warm up the car before driving a new energy vehicle. Especially when the temperature drops below 0℃ at night, the vehicle is placed in a low temperature environment overnight. When starting the car the next day, it is best to wait for 1 to 2 minutes after powering on to allow the vehicle's circuit and battery pack to preheat for a period of time before starting the car. This can extend the service life of the vehicle battery as much as possible.

 

6 Charge the car in time after using it

In winter, the car should be charged in time after using it to ensure that the remaining power of the car is above 20%. When using the car, the battery power cannot be completely used up. If the power is discharged, it may cause damage to the battery of the new energy vehicle. Every time the car owner drives, if the remaining power is about to fall below 20%, he should stop and charge in time.

7 Maintain good car use habits

Try not to use plugs and electrical appliances after turning off the engine, which will affect the service life of the battery. Try to control the air outlet position of the air conditioner to 1 to 2 gears, and turn on the in-car circulation mode at the same time, so that warmer wind can be blown out, and the power saving effect can also be achieved. In addition, people in the car can turn on the warm air intermittently, which can keep warm and avoid power loss.

 

8 Regular tire maintenance

Due to thermal expansion and contraction in winter, the tire pressure of the car will also decrease, resulting in greater tire rolling resistance and shorter mileage. It is recommended that car owners pay attention to tire pressure and refill air in time.
