Will fast charging of new energy vehicles shorten the life of lithium batteries?

The fast charging method generally uses a special off-board DC charger for charging, which is installed in a fixed charging station, connected to the AC input power source, and the DC output terminal is connected to the charging interface of the electric vehicle to be charged. High-power fast charging requirements for electric vehicles. At present, the batteries used in new energy vehicles are basically lithium batteries, and lithium is a more active element than sodium. Fast charging will make lithium too active, which will precipitate the electrolyte in the lithium battery, which will cause bubbles to appear, which is easy to make the battery Expansion can even cause the battery to explode, so the charging current is not easy to be too large or fast charging is as little as possible. Studies have stated that fast charging technology will reduce the service life of lithium battery packs, which also makes consumers always maintain the traditional concept of fast charging batteries. In fact, this statement is not absolute, not all batteries will be damaged when using fast charging. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
