Farasis Energy presents a new battery cell variant with a fast charging time of less than 15 minutes at 300 Wh/kg energy density

Farasis Energy – developer and producer of high-performance lithium-ion battery technology  – is expanding its fourth generation of battery cells for electric vehicles with an Ultra High Power variant that achieves a fast charging time of less than 15 minutes – with a high energy density of 300 Wh/kg.

This new variant has been externally tested by customers, and series production is planned for 2025.

Dr. Keith Kepler, CTO and co-founder of Farasis Energy, said: “When developing battery cells, manufacturers have long focused on range.The aim was to achieve the ranges of vehicles with combustion engines. We have been able to make enormous progress in this area in recent years. For example, the cells of The Farasis Generation 1 currently in use have an energy density of 285 Wh/kg, making them one of the leaders in the international market. Depending on the size of the battery, a range of more than 700 kilometers can be achieved.”

Dr. Stefan Bergold, General Manager at Farasis Energy Europe, said: “However, we are finding that, in addition to the desire for more range, the fast charging time is increasingly becoming the focus of automotive manufacturers and consumers. When developing our Ultra High Power variant, we have therefore brought both trends together by offering high energy density for long ranges and high performance for fast charging capability. This allows us to meet the requirements of our customers in both respects.”

The Ultra High Power variant of cell generation 4 from Farasis not only convinces with a higher energy density compared to previous cell generations, but also with a significant improvement in the fast charging time.

With this variant, the focus can be placed more on the range or more on the fast charging capability, depending on the customer’s wishes. In less than 15 minutes, the battery can be charged from 10 to 80 percent in fast charging mode.

The time to reach an additional range of 250 kilometers through fast recharging is even less than 8 minutes.

Drivers want to be able to quickly recharge the electricity for their e-car on the go,” explains Bergold. “Our goal is therefore to enable a charging process in the future that is in no way inferior to the conventional refueling process of a car with a combustion engine. With the new Ultra High Power variant of our cell generation 4, we have come a good deal closer to this goal.”
