Quantum batteries promise to fully charge electric cars in a matter of seconds



One of the great handicaps of this type of vehicle is the tedious load. The normal thing is that the batteries need between 6 and 8 hours to complete the recharge and if we are talking about the future (already present), it is an aspect to improve. Quantum batteries come with the solution.

A team of scientists from the Center for Theoretical Physics of Complex Systems at IBS (Korea Institute of Basic Sciences) has turned to the field of quantum physics to try to solve this big problem.

To give us an idea, the Tesla Model 3, in a home environment, charges in approximately 9 hours and 30 minutes with the Tesla wall connector. A Toyota Prius Prime (plug-in hybrid), on the other hand, takes around 5 hours and 30 minutes for a full charge.

Well, the team was inspired by a 2012 study, which proposed a concept of quantum battery, that is, a quantum mechanical system that acts as an energy storage device.

The basis of these batteries is that the battery cells are collectively charged as a whole. In contrast, conventional batteries are charged in parallel and independently, which slows down the entire process.

The car that Elon Musk promised so that anyone could have the opportunity to buy a Tesla is already a reality on the market. In this report we show you everything that this Tesla car hides.

As a consequence, the great advantage is the possibility of loading these vehicles in a much faster way. What’s more, found that the larger the battery, the shorter the time, unlike, once again, conventional batteries, where the higher the number of cells, the longer the charging time.

Thanks to the research process carried out, they concluded that if they went from one battery cell in an electric vehicle to 10 cells, the charging speed was multiplied by four, and if we went from one to 10 cells, the charging speed was multiplied by 100.

Taking into account that a typical vehicle has a battery of about 200 cells, quantum charging can charge 200 times faster than traditional batteries. This, in times, and according to estimates, charging an electric vehicle at home would be reduced from 10 hours to three minutes.

How many charging points for electric cars does Spain have? Let’s analyze how many recharging points for electric vehicles there are in Spain since it is a question that you are going to ask yourself if you want to buy an electric car.

Let’s not even talk about what would happen in high-speed charging stations where the time would be reduced to just a few seconds.

The problem with all this, as always, is that it is still in an investigation process and taking into account the times, it is likely to be a few years yet before it is introduced as the great alternative.
