As the saying goes: Haste makes waste. In fact, in the field of pure electric vehicles is the same principle, although fast charging can shorten the charging time, but also the greater harm to the battery. Isn’t it a bit surprising that a quick charge would harm the battery? Today, SmartPropel will together with you to talk about that.
There are several times when fast charging may have a big impact on your EV battery, it says. Avoid fast charging in extreme heat without preconditioning your battery. Preconditioning is when the car’s thermal management system pre-cools the battery so that it can accept a higher charge rate without overheating.
To get to the point, when the vehicle is being fast-charged, it will put a relatively large current into the battery immediately, which will affect the battery’s ability to restore. The reduction in battery power increases the rate of decay of the battery, which in turn affects battery life and overall performance.
In general, any quick charge will hurt the battery. But if the battery density, the material, the temperature, the battery management system of the electric vehicle, is properly designed, then the damage is within a reasonable range.
In August, Recurrent published a new report about the relationship between DC fast charging and battery degradation. “We compared cars that fast charge at least 90% of the time to cars that fast charge less than 10% of the time. In other words, people who almost exclusively fast charge their car and people who very rarely fast charge.
One day you wake up to find everybody and their grandmother is saying if you use DC fast charging to put electrons back into the battery of your electric car on a regular basis, your battery will degrade faster and lead to an expensive battery replacement. It’s something a lot of people believe, but is it true?
