FAST FIVE: Fast-Charging Stations Damage Tesla Car Batteries After Just 25 Cycles, New Study Shows
Fast-Charging Stations Damage Tesla Car Batteries After Just 25 Cycles, New Study Shows A new whitepaper shows that the “fast charging” feature of many Tesla charging stations along the nation's highways may actually be doing more harm than good.
But after that, the “fast charging” technique caused capacity to fade “much faster”.
In fact, after just 40 charging cycles, batteries only kept 60% of their storage capacity.
Batteries charged using internal resistance charging retained more than 80% capacity after the 40th cycle.
The blog then notes: “At 80% capacity, rechargeable lithium-ion batteries have reached the end of their use life for most purposes.
