It depends a lot on the type of battery and power used, but charging an electric car can take -according to Repsol’s calculations- between one and eight hours, depending on whether we use the slow or semi-fast system. In the event that we can use ultra-fast charging, the margin could drop even more, remaining below half an hour. They are important data. Together with the autonomy of cars, key to combating the fear of being stuck, it is, after all, one of the factors that can encourage us (or discourage us) when it comes to making the leap to EVs.
But… what if even five minutes was too much? What would happen if charging the battery of an electric vehicle took us more or less the same as filling the tank of an internal combustion car, about two minutesaccording to the calculations of the American Petroleum Institute?
Morand eTechnology ensures that we do not need to speak conditionally. Its technicians have developed hybrid battery technology that would allow a city car to be recharged to 80% in a matter of 72 seconds. Reaching 98% charge would take 120 seconds and reaching 100% would require 2.5 minutes. Its eTechnology system would thus offer times capable of being measured with the refueling of combustion vehicles. The key: the combination of hybrid ultracapacitor cells (HUC) from the company Sech SA and advanced controllers to recharge and discharge quickly.
Goal: save charging time
Another advantage of eTechnology, claims Morand, is the long service life of their devices, superior to conventional lithium-ion batteries. “While typical chemical batteries can have a useful life of between 3,000 and 5,000 cycles, the cells in our power packs can easily complete more than 50,000 cycles with a C-rating of 50,” claims Morand, who ensures that his system it has already been independently tested. Some units would have gone even a little further in their resistance results, withstanding even up to 70,000 cycles.
During tests with three modules of 400 V and 2.4 kWh each one would have demonstrated its ability to recharge in less than two minutes with a power of up to 900A/ 360 kW. Its hybrid system, the company explains, uses an energy accumulator with a capacity of 7.2 kWh and stores enough energy to cover up to 70 kilometers in a small city car in a totally electric way or around 305 kilometers in hybrid mode.
The name of the Swiss company still rings a bell, albeit for slightly different reasons than electric vehicle technology. Its founder and General Manager is Benoît Morand, a former racing driver who came to create his own team in 2000. Morand came to promote hybrid technology for competition and his role was key in the development of the Hope Racing Oreco 01 Hybrid, the first prototype of this guy who started at the 24 hours of Le Mans, more than a decade ago.
Its technology is promising, although the tests, New Atlas points out, would have been carried out with a 7.2 kWh prototype, which leaves them quite far from the 100+ kWh battery packs of some of the vehicles with the longest range. From the market. The devices would in any case be an interesting option for small urban vehicles, similar to the Citroën Ami, or for recharging other battery-powered devices, such as drones or electric bikes.
The company – details Interesting Engineering – calculates that a bicycle of this type with a 6 Ah battery could be recharged with its technology in six minutes at a speed of less than 3.2 kW. Another of the advantages that Morand claims, in addition to the speed of charging and duration of the batteries, is their ability to operate efficiently even at high temperatures.
