New Energy Vehicle Charging: Your FAQs Answered

Nowadays, more and more people are buying new energy vehicles, and they will encounter some minor problems when charging electric vehicles. Let’s learn about the common problems when charging electric vehicles.

1. Why does charging take longer in low-temperature environments?

Answer: This is related to the vehicle battery. In low low-temperature environment, the charging activity of the battery is reduced,

which will lead to a decrease in charging efficiency. In addition, to better protect the battery,

the battery management system of some car companies will first heat the battery pack at a lower current when starting to charge.

The lower the temperature, the longer the heating time, until the battery temperature rises to the level required for battery activity.

temperature, so the charging time is extended, and it has nothing to do with the charging equipment.

2. How to reduce energy consumption when driving in winter?

Answer: It is normal for new energy vehicles to increase their energy consumption in severe cold weather.

Electric vehicle batteries are greatly affected by low temperatures.

When the temperature drops, the viscosity of the electrolyte in the battery will increase,

causing the battery to lose power faster, thus affecting the electric vehicle’s performance.

The car’s cruising range. Energy consumption can be reduced by adjusting the temperature of the air conditioner,

turning on energy recovery, and reasonably increasing tire pressure.

Of course, it is also necessary to avoid charging the battery with a large amount of empty power, resulting in “false battery life.”

3. Why does the charging display show that it is fully charged but the meter mileage shows that it is not fully charged?

Answer: The remaining mileage of the instrument is calculated based on the available power in the environment where the vehicle is located and the energy consumption of the NEDC comprehensive situation,

and will be affected by multiple factors such as the environment and even driving habits.

Under low-temperature conditions in winter, due to the reduced activity of lithium batteries,

the discharge capacity of the battery will be affected to a certain extent.

The vehicle system of some vehicles will correct the cruising range downward to ensure the accuracy of the cruising range, regardless of the charging equipment.

4. Will using entertainment software for a long time to watch movies and listen to music affect battery consumption?

Answer: Vehicle energy consumption mainly comes from high-voltage systems and low-voltage systems. High-voltage includes a drive system, air conditioning system, and battery temperature control. Low-voltage systems include entertainment, lighting, and other systems. Entertainment software is one of the low-voltage system components and has a small impact on energy consumption. However, energy consumption adds up. When the battery life is small, turning off the entertainment function can alleviate battery energy consumption to a certain extent.

Will listening to music after the car is turned off harm the battery

5. If the car is not used for a long time, does it need to be fully charged?

Answer: If the vehicle is idle for a long time, the vehicle should be charged regularly to prevent the battery from being overcharged and depleted for a long time,

which will affect the battery life and reduce the battery performance. It is worth noting that SOC 20%-90% is a reasonable range of remaining power.

If it is lower than 20% or higher than 90%, it will cause battery performance to decline and damage battery life.

Overcharging or loss of power is not recommended. When the parking time exceeds 1 month,

it is recommended to park the vehicle in an indoor parking lot to avoid parking the vehicle in a low-temperature environment for a long time.

6. Why do vehicles sometimes lose power at night?

Answer: It is understood that although some vehicles are not driving at night, some systems will be in working condition and energy consumption will occur. If power outages occur frequently at night, you can contact the 4S store for testing.

7. How to shorten the charging time and increase the charging speed in winter?

Answer: In areas with colder winters, if you want to increase the charging speed, you can choose to charge indoors or in a place with a suitable temperature. As much as possible, charge as you go. After using the car, the battery will have residual temperature and the battery activity will be strong, which can increase the charging speed.

Will fast charging really damage the battery

8. Will fast-charging damage the battery?

Answer: According to the research report of China Automotive Information Technology Co., Ltd.

and the information released by the Internet Joint Rumor Refutation Platform, the statement that “fast charging will damage the battery” is not accurate.

At present, the rationality and technological advancement of BMS (battery management system), battery density, materials, temperature, etc.

are fully considered in the design and development process of new energy vehicles, which has greatly reduced the impact of fast charging on battery cycle charging life.
