Charge 80% in 72 seconds! Hybrid super capacitor battery is expected to be used in urban EV instead of lithium battery

AP Shanghai, November 22 (Editor Huang Junzhi) For a long time, it has been the dream of scientists and manufacturers to shorten the charging time of electric vehicles, or even match the refueling time.

Recently, Morand, a Swiss technology startup, has developed a new electric energy storage technology, which can shorten the charging time of electric city vehicles by more than half. As a mixture of traditional batteries and supercapacitors, the company’s electronic technology department provides the possibility of charging rates that are expected to change the rules of the game, as well as longer life than lithium ion batteries.

Morand has been working hard to develop the so-called “eTechnology” technology, which is described as an energy storage solution combining the characteristics of super capacitors and chemical batteries. As a part of the test and evaluation project, the company said that a 7.2 kWh eTechnology prototype can be charged to 80% in 72 seconds, 98% in 120 seconds and 100% in 2.5 minutes under 900 A/360KW.

Of course, 7.2 kWh is far from the battery pack of more than 100 kWh used by some electric vehicles with the longest endurance on the market. Morand has been focusing on small capacity applications, such as unmanned aerial vehicles and electric bicycles. He explained that eTechnology is most suitable for applications requiring fast and semi frequent charging (charging time is less than five minutes). 7.2 kWh battery pack will be suitable for small city cars similar to Citroen Ami.

For electric bicycles, Morand estimates that a bicycle equipped with a 6 Ah battery can be fully charged in 6 minutes at a low rate of 3.2 kilowatts. This will change the rules of the game for electric bicycles, which usually require several hours of recharging. This could make electric bicycles a more viable alternative to cars for daily commuting and errands.

In addition, other advantages of eTechnology mentioned by Morand include efficient operation at extreme temperatures and the potential for more charging and discharging cycles. The company claims to have safely tested more than 50000 cycles, dozens of times more than traditional battery packs.

Morand said that the company is cooperating with a production partner to carry out small batch production, and plans to increase the output to make eTechnology more competitive with lithium ion batteries in terms of cost. The company is also looking for investors to fund the expansion of production scale.
