Suppliers are competing for power to offer ever faster recharges to electric vehicles. Refueling is now almost as fast as with a gasoline car.
The problem of recharging time is one of the main obstacles to the adoption of the « the fastest charging station in the world », Capable of providing 100 km of autonomy in less than three minutes. With a power of 360 kW (compared to 300 kW for the very latest for example), the 360 allows a full recharge in 15 minutes or less depending on the vehicle. Better still: it can simultaneously charge four cars, which means that the user does not have to wait when the terminal is already taken.electric. No one really wants to wait several hours on the highway to refuel. That’s why automakers and tech companies scramble to find fast charging solutions. The Swiss group ABB has thus

The Terra 360 will be available in Europe by the end of the year and in the Americas and Asia regions in 2022.
Electric car: charge its battery in 10 minutes, it’s possible

It’s the holy grail of electric vehicles: fast charging is the fundamental problem for now. But researchers have, it seems, found a way to get around the difficulty even if there are still many obstacles to overcome before moving on to the industrial stage.
Ten minutes of electric recharging for 320 kilometers of autonomy: this is the technological success, for the moment experimental, of a team of engineers from the American University of Penn State, which hopes that one day it will make it possible to solve a fundamental problem of.
To get to swallow so muchto a battery in record time, the researchers raised the temperature of an experimental battery to 60 ° C during the recharge time, then lowered it to ambient level during use, according to their study published Wednesday in review Joule.
By varying temperatures in this way, the researchers avoided the types of wear and tear that occur when aworks at high temperature. The battery life would even be extended.
A decade before removing the obstacles?
« The key is to achieve rapid heating, otherwise the battery will stay at a level ofhigh too long, which greatly degrades it Explains co-author Chao-Yang Wang. Going to an industrial level will probably take a decade, believes Rick Sachleben, a retired chemist and member of theAmerican Chemical Society and which has nothing to do with the study published on Thursday. It will be necessary to ensure that these extremely fast recharging techniques are stable, safe and do not lead to explosions, given the temperature and the phenomenal amount of energy transferred.
« Fast charging is the holy grail of electric vehicles, the chemist told AFP. It is one of the essential things to really compete with the“. Today, indicates for example that it takes 30 minutes to recharge its partially at its terminals on the road. To refuel, gasoline cars are unbeatable.
