Huawei applies for a SuperCharge trademark in the EU

Last year Huawei showed a battery with 3.000 mAh capacity and an energy density above 620 Wh/L getting charged to 48 % in just 5 minutes.

Back then Huawei said:

“Huawei is confident that this breakthrough in quick charging batteries will lead to a new revolution in electronic devices, especially with regard to mobile phones, electric vehicles, wearable devices, and mobile power supplies. Soon, we will all be able to charge our batteries to full power in the time it takes to grab a coffee!”


Now it seems the company is ready to use the technology in their smartphones with the recent application for the SuperCharge trademark in European Union.


I actually think that testing batteries in smartphones is a great idea. The battery in a smartphone is actually a single cell that’s always in use, this way we can follow its performance closely. Since the phones are also very compact electronic devices they tend to get hot very easily, this is also good to test the cell’s endurance in high temperatures.

Charging from 0 % to 48 % in 5 minutes means a 5,76 C-rate charging. For example this would make a 30 kWh battery able to charge at 172,8 kW. This is more than the soon to be available 150 kW DC fast chargers with CCS and CHAdeMO protocols. Of course that as the charging progresses the C-rate also drops, so this could be a good combination.

Huawei is expected to start using this technology later this year or early 2017 in their new smartphones. By then some cell makers might get this tech to make electric car batteries.

To put it in a context, the 24 kWh battery in a Nissan Leaf is built with AESC cells that have an energy density of 317 Wh/L. The increase to 620 Wh/L would mean a 47 kWh battery that could be charged at 270 kW in a fast charger. Since 270 kW chargers aren’t available yet, we would have to be content with 0 % to 80 % charge in 15 minutes with a 150 kW charger.

Usually I don’t waste my time with future battery technology news, because in most cases they are nothing more than fiction, but this is very promising and it’s almost here.

My interest in electric transportation is mostly political. I’m tired of coups and wars for oil. My expectation is that the adoption of electric transportation will be a factor for peace and democracy all over the world.

Do they manfacture there own batteries or just engineer this tech?
