“We have completed preliminary testing of our prototype pack with fast charging capabilities, and we’re proud to announce that we did better than expected. We beat our charge time by 2 minutes and 25 seconds by charging a 3 kWh pack to full in 12 minutes 35 seconds,” said Mark Hanchett, CEO of Atlis. The company uses an EVgo Level 3 fast charging station in the Phoenix area as a test site. “This was the key to proving our technology – recharge times for batteries is still one of the largest obstacles to wider adoption of electric vehicles,” said Hanchett.
The prototype battery is a lithium-ion cell with a unique cooling system for optimum temperature management. “Properly managing cell temperatures is still overlooked by many electric vehicle manufacturers but is one of the most critical components to battery performance and longevity. Ignoring temperature management, or just providing mild surface cooling of the cells is insufficient,” he added.
The battery pack is part of Atlis’ prototype design and is capable of scaling in size to meet a range of performance needs. The capacity of the test pack had to be kept low to ensure enough power was available from the Level 3 charging station. Next steps for the prototype pack is to integrate this design concept into Atlis Motor Vehicles’ XP platform currently in development.
