Fast charging your EV might not be as bad as predicted
Stanford, MIT, Sandia Show Rapid Charge, Discharge Cycle Likely Balanced In Pack
The study itself is chock full of really scientific terms, but the crux is that a larger percentage of a battery's particles are absorbing the ions during the quick recharge than previously though. That means that instead of the effects of the recharge and discharge being felt by a small percentage of battery cells, the impact is likely more balanced and spread out through the battery, according to the new report. That essentially means less wear and tear.
The subject matter is topical because of the gradual expansion of charging infrastructure that includes more powerful systems like the Tesla Supercharger network and BMW's new i DC Fast Charger. In fact, Tesla just deployed its 200th Supercharger worldwide, and has about 115 in North America. Those stations can add as much as 170 miles of range to a Model S in just 30 minutes, and that sort of speed might not be all that bad for the battery, either.
