Does Fast Charging Damage Car Batteries. For electric car drivers on the go fast-charging stations can be a lifesaver especially when driving over a long distance however recent studies have found that regular use of fast charging stations can cause damage to EV batteries and decrease their overall lifespan but its not all bad news. Wang noted that fast charging must also be repeatable at least 500 times without degrading the battery to give it a reasonable life and that the EC power battery can do so 2500 times.
Up until recently there has been very few long term real life studies. Storing it fully charged or fully discharged will damage it more than if you leave it somewhere between 40 and 80. Some users may object.
The effects of fast charging of lithium titanate cells finding minimal capacity fade throughout their experiment while charging at a 6C rate which charges a battery at a peak current equal to six times the battery capacity per hour 2.
The bottom line is fast charging wont impact your battery life substantially. To remedy the issue found with fast charging stations the researchers have developed a method for charging at lower temperatures with less risk of damage and loss of storage capacity. Will frequent fast charging if the EV supports it affect the batterys lifespan. And while the batteries found in laptops and mobile phones can be damaged if theyre charged at high power consecutively electric vehicle batteries wont.
