Fully Charged in Just 6 Minutes – Groundbreaking Technique Could Revolutionize EV Charging::Typically, it takes around 10 hours to charge an electric vehicle. Even with fast-charging techniques, you’re still looking at a minimum of 30 minutes – and that’s if there’s an open spot at a charging station. If electric vehicles could charge as swiftly as we refill traditional gas vehicles, it wo
Tesla semi is meant to be able to charge at 1mw, which makes sense considering the size of the battery, bigger battery means more cells and more space for cooling. The truck is also meant to support 1mw with the new v4 chargers. So if you believe Tesla (which is hard because of Musk), it is coming.
Charging that rapidly is only possible for some but not all 100% of the battery as you have to slow down as you approach 100%. 350kw chargers slow down around 80% (I’ve gone as high as 85% before I’ve seen the slow down). This happens at all charging speeds to protect the battery, even 7kw chargers slow down for the last couple of percent.
However charging to 100% of the time on ultra rapid chargers is monumentally dumb as it’s considerably more expensive per kWh than slow chargers, slower for that last 20%, blocks chargers for longer, and isn’t good for the long term health of the battery. It is as quick to charge twice to 80% than it is once to 100% on the same charger for 60 to 70% more range from charging twice. This is true because you avoid slowing down at the end of the charge.
You’re speaking with current lithium battery technology in mind. Supposedly, scientists in the article figured out a new technology that can be charged in 6 minutes. No word on whether it’s still necessary to slow down at the end, or charging efficiency. Time will tell I guess
