A Company is Testing EV Batteries Capable of Charging at 900 kW

New chemistry could allow for more powerful and cheaper battery packs

  • These batteries could charge from 0 to 80% in about 5 minutes

  • A new chemistry can allow more power to be stored in a smaller battery

  • The first car to use this technology should be the Piëch GT

Charge times are probably the most important factor that limits adoption of electric vehicles because they can make longer trips inconvenient.

Thus, many companies are working to make batteries that can be charged in the same time it takes to refuel a gasoline powered vehicle.

One of these companies is Desten, a business specialised in EV batteries that is operating out of Hong Kong.

The batteries produced by this company will be able to take charges of up to 900 KW, which is about three times more than the Porsche Taycan, the current vehicle with the fastest charge rate.

By developing a new chemistry and a different configuration for the battery cells, Desten was able to create a battery that is extremely thermally stable and resitant to overheating, thus allowing for very high charging rates. This thermal stability also allows the company to forgo a liquid cooling system for the pack, which reduces size, weight and costs, three major drawbacks to current EV batteries.

Since the temperature of the pack never exceeds the ambient temperature by more than 15˚C, Desten was able to obtain multiple safety certifications.

A 75-kWh version should be used in the upcoming Piëch GT electric sports car and this technology should allow it to have around 500 kilometers (310 miles) of range (WLTP) but most importantly, it should be able to charge from 0 to 80% in only 4 minutes and 40 seconds.

Other advantages of this new technology include a good potential for regenerative braking and the durability to sustain about 3,000 charge cycles, meaning the packs should be good for about 1.5 million kilometers before needing replacement.
