Amprius ships EV battery that reaches 90% charge in 15 minutes

Amprius Technologies has shipped its power-packed A-Sample EV cells to the United States Advanced Battery Consortium (USABC), a research collaboration between major automakers to advance EV battery technology. Amprius’ new SiMaxx cells hit an impressive 360 Wh/kg in energy density – far beyond the USABC’s target of 275 Wh/kg. What does that mean for EV drivers? Simply put, longer range without a bulkier battery. Plus, these cells have a power density of 1200 W/kg, meaning more efficient energy delivery. One of the standout features here is the charging speed. The A-Sample EV cells can go from empty to 90% in just 15 minutes, which exceeds the USABC’s target of 80% in the same amount of time. Amprius’ internal tests are also showing progress toward achieving 1,000 charge cycles. USABC is a subsidiary of the United States Council for Automotive Research (USCAR), the collaborative technology company of Ford, General Motors, and Stellantis. This US Department of Energy (DOE)-supported collaboration aims to drive forward the adoption of cutting-edge battery tech for EVs. Amprius has been working closely with USABC and the DOE on these cells as part of a $3 million contract awarded in May 2022. The delivery of these sample cells marks the final milestone in that development project. Amprius is in talks with major automakers about adopting this tech more widely. To meet market demand, Amprius has agreements in place for over 500 MWh of contract manufacturing. This means they’re ready to scale up and get these batteries into as many EVs as possible. With the automotive world increasingly focusing on cleaner energy, Amprius’ batteries could be a game-changer. Amprius CEO Dr. Kang Sun said, “With their superior energy and power performance, fast charging, wide operating temperature range, and safety features, Amprius is continuing to transform the EV sector and other electric mobility segments as we scale toward high-volume manufacturing.”
