This new technology could make it possible to charge an electric vehicle in less than three minutes


One of the weak points of electric cars current, there is battery charging, which can take a long time. This is one of the points that still discourage consumers from purchasing these vehicles, which are ecological after all. According to the American Petroleum Institute, it takes an average of two minutes for a gas-powered car to be full. This is far from being the case for electric cars, but that could soon change a new technology for the storage of electrical energy developed by a Swiss company.

The relevant company is called deadand it could offer electric vehicles a cooldown never reached: less than three minutes. According to reports, the new technology, which bears the name ofeTechnologyis a combination of traditional batteries and ultra-capacitors. It promises breakthrough charging speeds and the ability to outlast lithium-ion batteries.

System capabilities

According to Morand, his new technology is a solution that combines the characteristics of an ultracapacitor and a chemical battery. During testing, a 7.2 kWh eTechnology prototype could charge to 80% in 72 seconds, 98% in 120 seconds and 100% in 2.5 minutes at a maximum of 900 A/360 kW. Independent testing has been carried out by Geo technology.

Regular customers of electric cars will have understood that 7.2 kWh is still a long way from the battery packs of 100 kWh and more electric vehicles on the market. In fact, Morand focused on small household appliances such as drones or e-bikes. According to the company, the eTechnology would be best suited for applications that require fast, semi-frequent charges of five minutes or less. Cars that would fit the 7.2kWh battery would be small city cars like the Citroen Ami with a battery pack of 5.5 kWh.

As for electric bicycles, Morand indicates than an e-bike owning a 6 Ah battery could be charged in six minutes with a lower power of 3.2 kW. It would be a revolution in the field as these bikes generally take several hours to charge.

Benefits

One of the benefits of eTechnology mentioned by Morand is the efficient operation at extreme temperatures. The system also allows it more charge/discharge cycles. The company says it has tested the system with more than 50,000 cycles, which is dozens of times that of traditional battery packs.

According to Morand, they are currently working with an associate on a small production. However, the company plans to increase production to make eTechnology more cost-competitive with Li-ion batteries.
