Huawei’s new EV battery patent

Huawei, a company renowned for a lawsuit regarding how its affordable phones come with a built-in line to the Chinese government, has been making waves in the electric vehicle industry. The company has decided to throw its Dǒulì (a traditional Chinese hat) into the ring of EV batteries, potentially changing the entire game.

According to a patent for a new battery system, Huawei believes it can develop a sulfidic solid-state battery that can theoretically power a car for a range of 3,000 kilometres. More astoundingly, they believe you’ll be able to charge the entire thing in under five minutes.

Now, this is a massive claim that obviously needs to be taken with a pinch of salt, or maybe a few kilograms of it. Huawei has already developed the M3P hybrid batteries, which power the Luxeed S7 and AITO M9, two cars you have never heard of. These batteries are already impressive. They’re composed of a clever blend of lithium iron phosphate and nickel manganese, pushing ranges into roughly 700 kilometres, which, compared to the Tesla Model 3’s range of 500 kilometres, is astounding.

So, how possible is a 3,000-kilometre electric vehicle? Well, it currently seems just as possible as BMW drivers who know how to indicate, or in other words, it seems impossible. This whole patent is highly hypothetical; Huawei hasn’t built it or tested it yet, so we can’t say for sure if this is possible or not.

However, a fully charged battery is estimated to weigh nearly one ton, which is approximately the weight of two whole Ariel Atoms. So it’s difficult to imagine how practical it would be to implement this as a car’s primary power supply.

A battery with a range of 3,000 kilometres and charging faster than it takes for the petrol station sushi to work its magic would be a massive step forward for the EV industry. However, we have to keep in mind that this technology is still in its early stages and may never see the light of day.

However, this raises a personal qualm with the EV industry. Current electric vehicle batteries only have an average lifetime of 10 years or 100,000 miles, and are notably difficult to recycle. I firmly believe that extending these batteries’ life span is potentially even more important than boosting vehicle range and charge times. But even still, Huawei’s developments in the space are incredibly impressive and something to definitely keep an eye on.
