How do you view the impact of fast charging on electric vehicle batteries?

China [CN]

Overview: There are different opinions on electric vehicle charging in society. Among them, the charging mode is particularly important for the user experience of electric vehicles. Of course, facing different charging modes, different impacts on the battery have occurred.

The impact of fast charging on electric vehicle batteries is a complex and multi-dimensional topic, which can be clearly and inductively analyzed from the following aspects:

Positive impact:

Improving the convenience of use:

Fast charging technology can significantly shorten the charging time of electric vehicles and improve the convenience of users. Compared with traditional slow charging, fast charging technology can replenish a large amount of power for the battery in a shorter time, meeting the user's needs for fast energy replenishment.

Negative impact

Shortening battery life:

Fast charging will accelerate the chemical reaction inside the battery, causing damage to the internal structure of the battery, thereby shortening the battery life. Although the battery management system (BMS) of modern electric vehicles can adjust the charging speed and current to a certain extent to protect the battery, long-term and frequent use of fast charging will still have a certain impact on the battery life.

Charging infrastructure dependence:

The convenience of fast charging also depends on the degree of perfection of the charging infrastructure. If the number of charging stations is insufficient or unevenly distributed, users may not be able to find available fast-charging stations in time, thus affecting the use experience of electric vehicles.
