THE WORLD'S GREATEST INNOVATION AND ENGINEERING CHALLENGE CONTRIBUTING TO A MORE SUSTAINABLE MOBILITY FUTURE

Amprius’ partner solar cars swept the top four places in the 2023 Bridgestone World Solar Challenge.

Our batteries outperformed throughout the most rigorous solar car race in the world, requiring teams to design, develop, and pilot a solar-powered vehicle along a tumultuous 3,000-kilometer transcontinental Australian route with extreme winds and low light from the northern city of Darwin to the southern city of Adelaide.

The four vehicles powered by Amprius ultra-high-energy cells “reported around 30% better capacity in the battery for roughly the same amount of weight of units used by other competitors,” resulting in finishing in the top 4 places. – Cosmos Magazine

University of Michigan Solar Car Team: built Astrum with a team of undergraduates and postgraduates from the University of Michigan in Ann Arbor, Michigan.
"Our primary reason for selecting Amprius batteries was their unrivaled gravimetric energy density, allowing us 3 kWh more than a conventional lithium-ion battery pack. As we began manufacturing and testing the battery packs, we were impressed with the thermal performance of the cells in addition to their high capacity. To have this level of performance while running cool, reliable and safe truly blew us away."

Innoptus Solar Team: built Infinite with a team of students from KU Leuven in Leuven, Belgium.
"With the high energy density cells from Amprius we were able to drive much faster than with conventional Li-ion cells. We could build the smallest battery pack ever for the same weight as previous battery packs that could fit in our aerodynamic nose of the car. And that with 30% more energy!"

Solar Team Twente: built RED X with a team of students from the University of Twente and Saxion University of Applied Sciences in Enschede, Netherlands.
"Collaborating with Amprius has been an amazing opportunity. Using their silicon anode battery cells has allowed us to increase battery capacity while reducing battery weight! This allowed us to drive even faster through the Australian outback, giving us a decisive advantage during the Bridgestone World Solar Challenge."

"To help enable these teams to capture the top 4 positions in the world’s most demanding solar car race is remarkable,” said Kang Sun, CEO of Amprius. “This is a testament to the intense preparation and determination from all four teams. We’re extremely proud our Silicon Anode Batteries proved capable of increasing vehicle range on the world stage amid extreme environmental conditions."
