Prototype battery pack charges in less than 13 minutes
Atlis Motor Vehicles, a startup electric pickup truck manufacturer, announced that it has completed and successfully tested its first large-scale prototype battery pack. The goal of the test was a full charge in 15 minutes, and Atlis says it achieved the full charge in 12 minutes, 35 seconds. This charge time of a vehicle battery in under 13 minutes is a first in the electric vehicle (EV) industry.
"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," CEO Mark Hanchett stated. Atlis Motor Vehicles selected 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."
The prototype battery is a lithium-ion cell with a unique cooling system designed 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," Hanchett added.
The battery pack is part of Atlis' prototype design, and the company says it can be scaled in size to meet the customer's performance needs. The capacity of the test pack had to be kept low to ensure that enough power was available from the Level 3 charging station. The next step for the prototype pack is to integrate this design concept into Atlis Motor Vehicles' XP platform currently in development.
