How to solve it?

New energy owners should take a look

Planning travel, charging on demand and saving power

The principle of "charging while using" shall be adopted

In winter, the battery performance of new energy vehicles will be affected by the drop in temperature, resulting in the shortening of battery range. Tips: achieve more power saving when charging while using.

Before travel

Be sure to plan according to the actual mileage

Avoid running out of power and anchoring on the road

My tram is slow charging or unable to charge

Mainly because

01 Automobile batteries generally have the function of low temperature protection. When the battery temperature is low, it needs to be preheated, otherwise the charging will be slow or even impossible.

02 We can prevent in advance. For example, in winter, when the battery is still hot, the battery will be charged after each use of the vehicle, so that it can be charged on demand. This not only reduces the charging time, but also protects the battery.

03 Mastering the charging time of the battery is also the key to power saving. Generally speaking, when the battery power reaches 20% - 30%, you can consider charging. If the vehicle is parked for more than a week, try to charge it once.

It is not necessary to charge 100% every time

80% - 90% is more ideal

Overcharging will damage the battery

Indoor charging is more comfortable

It is more convenient to charge during the day

In cold winter, the battery performance of new energy vehicles will be greatly affected. Due to the characteristics of the battery, when the temperature drops, the activity of the battery electrolyte will be reduced, and the charging and discharging capacity will also become worse. Therefore, it is a good choice to find a warm home for your car. When the ambient temperature is low, the activity of lithium battery will decrease by 10% - 20% in varying degrees, or it is necessary to find a place with sunshine that can shine on the parking space in the daytime to charge your car.

The optimal operating temperature of the power battery is about 25 ℃ New energy vehicle charging pile

It is safer to warm the car properly

Warm up the car at low speed

As we all know, fuel vehicles need to be warmed up in winter to reduce engine wear and carbon deposition. Similarly, new energy vehicles also need to be properly warmed up after starting. Because only when the battery temperature rises, the internal power can be released more effectively.

The fuel car is usually heated by parking after ignition

So, how to warm up new energy vehicles

01 After starting the vehicle, the new energy vehicle should avoid rapid acceleration or high-speed driving, but should allow the vehicle to drive at a low speed for a period of time. In this way, the battery can be gradually heated up to achieve the ideal state of charging and discharging. At the same time, low speed driving also helps to preheat other car parts, such as motors, electronic controls, etc., to extend their service life.

02 In the process of hot rolling, avoid standing still for a long time. Because this will not only waste energy, but also cause unnecessary wear on vehicle parts. The correct way is to drive at a low speed immediately after starting, and gradually increase the speed to make the vehicle enter the normal driving state.

How to make your car comfortable in winter

Then look down

Pay attention to vehicle maintenance, safety always comes first

01 Charging environment If the charging environment is too cold or too hot, the battery aging will be accelerated. If the battery is parked in a cold environment for a long time, the performance of the battery pack will also be adversely affected. When charging, remember to keep the charging plug clean and dry to prevent frost, snow and melted water from seeping into the plug in winter.

02 Check the protective cover of the charging port. If there is a gap, the charging port may freeze in winter. Therefore, cleaning the charging port when charging can avoid the false connection caused by the existence of ice, and on the other hand, avoid the leakage risk of high-voltage live parts.

03 Regularly check the tire pressure and wear. The tires of new energy vehicles are different from ordinary vehicles, so more attention should be paid to the tire pressure and wear. If the tire pressure is too high or too low, it will affect the driving safety of the vehicle, so you should regularly go to a professional repair shop for inspection and adjustment.

04 Pay attention to the battery health of vehicles The battery of new energy vehicles is the core component, and the battery health directly affects the performance and safety of vehicles. Therefore, in the process of daily use, it is necessary to regularly check the battery power and usage, and whether the battery pack is firmly connected.

Tips for using new energy vehicles in winter

01 Driving habits

When driving in winter, try to keep a constant speed and avoid sudden acceleration or braking, which can effectively reduce the loss of brake pads and the speed of battery power consumption. In addition, adjust the air volume and temperature reasonably to avoid using high-power air conditioners for a long time, which may affect the battery life.

02 Driving in Snow

Avoid driving on roads with deep snow to avoid falling into snow or sideslip. Keep the speed moderate to avoid sudden acceleration or braking, so as to avoid losing control of the vehicle.

03 Ice and snow cleaning

When using the electric vehicle in winter, it is also necessary to pay attention to the cleaning of the ice and snow on the vehicle surface. Since the battery and motor of the electric vehicle are located at the bottom of the vehicle, the ice and snow on the vehicle bottom should be removed in time to avoid damage to the battery and motor.

04 Emergency handling

If the vehicle fails to start or fails, immediately contact the after-sales service center or professional maintenance personnel for inspection and maintenance; If the vehicle is stuck in the snow and cannot move, call the emergency rescue number immediately for help from the car service.

New energy vehicle - you ask me

01

Can I charge it outdoors in rainy and snowy days?

Yes, but waterproof work should be done well. It is easy to have rainy and snowy weather in autumn and winter. At this time, the air will become humid. Many car owners worry that the humidity of the air will affect the insulation. Please rest assured that the charging pile itself is not charged until it is connected to the vehicle and starts charging. Therefore, in the rainy and snowy weather in autumn and winter, when charging, as long as the vehicle interface is not in the rain and the gun head is dry, you can start charging normally.

02 What should I do if I cannot start the charging post normally?

First, it is necessary to determine whether the failure of the charging pile to start is caused by operation or temperature. Check whether the charging gun is used correctly and whether the interface of the charging gun is connected properly; Check whether the emergency button is touched by mistake; If the above two conditions are excluded, it is necessary to consider whether the problem of the temperature control system is caused by the low temperature in winter. It is recommended to switch to the indoor or underground parking lot for charging.
