Charging That Electric Vehicle? Soon It Might Not Take as Long

(DGIwire) – The UK government recently announced a total ban on the sale of new gas and diesel vehicles beginning in 2040, according to a recent article in TransportXtra. Good for the environment? Yes. Will there be roadblocks along the way? Yes again. In fact, there will be three distinct challenges to overcome, writes Stephen Voller, author of the TransportXtra article and CEO of ZapGo Ltd, the developer of Carbon-Ion™ (C-Ion®) cells, a fast-charging and safe alternative to lithium-ion batteries.

The first challenge, notes Voller in TransportXtra, involves establishing an adequate driving range for electric vehicles (EVs). The second entails providing sufficiently fast charging times. And the third requires ensuring that appropriately high levels of energy can be transferred from the existing electrical grid to EV charging stations.

“The solutions to these challenges may lie in a process that is known as extreme fast charging,” Voller writes. “This can give EV owner the ability to recharge their vehicles in as little as five minutes, as quickly and conveniently as filling up a conventional vehicle with gasoline.”

Range anxiety is commonly cited as one current reason for consumers’ hesitation to buy a battery EV. Extreme fast charging has the potential for overcoming this roadblock, making these vehicles a practical solution for long-distance travel. At the very high charge rates permitted by extreme fast charging, battery EVs can achieve a 300-mile range in just five minutes, according according to the TransportXtra article.

This range can be enabled by the incorporation into battery EVs of a burgeoning technology known as Carbon-Ion (C-Ion), developed by ZapGo. C-Ion technology does not require any of ther lithium, cobalt, nickel or sodium needed in traditional EV batteries, and negates the growing concerns about ocean mining to obtain some of these elements. C-Ion cells represent a novel class of energy storage devices that incorporates nano-structured carbons, an ionic electrolyte and improved fabrication technologies. They can be easily used alongside existing lithium-ion cells on board EVs.

With the use of C-Ion cells, energy can be safely transferred to EVs using extreme fast charging rates greater than 350kW. This can help ensure that the wait time at the charge station can be reduced to five minutes or less. This ultra-high transfer rate is possible because C-Ion can charge and discharge very quickly and also because C-Ion does not catch fire, so it is perfectly safe to have a large energy store on site next to existing storage tanks of gasoline and diesel. Where filling stations already have EV charge points, these can be upgraded to 350kW by installing this system.

“With an EV future clearly approaching in a range of nations around the globe, overcoming the current technological gaps is a must,” Voller adds. “Ongoing progress in overcoming these challenges today points the way toward a cleaner tomorrow.”
