To mitigate any potential hazards, battery packs are automatically disconnected if any component deviates from its operating specifications and design limits.ī2U’s energy storage systems deliver a superior CapEx and Levelized Cost of Storage (LCOS) advantage. EPS cabinet controllers and ancillary equipment sense and manage the internal cabinet environment surrounding each battery pack. In addition to being certified to UL 9540, the system continuously monitors and controls each battery to ensure operating specifications are maintained. The EPS system provides safe and reliable operation 24/7. This approach enables our system to achieve efficient energy yield despite the variance in capacity inherent in second life batteries.” “The EPS system’s Cabinet Controllers connect and disconnect batteries wired in series and parallel strings during charge and discharge cycles so that weaker batteries with lower capacity do not limit the output of stronger batteries. EV battery packs are deployed in cabinet enclosures utilizing the pack’s existing battery management system, virtually eliminating repurposing costs.” said Freeman Hall, co-founder and CEO of B2U Storage Solutions. “B2U’s EPS technology has been developed to address the challenges of second life in large scale energy storage. In addition to deploying Honda and Nissan EV batteries at scale, B2U has successfully tested GM Bolt and Tesla Model 3 battery packs with its EPS system, demonstrating the ability of the EPS system to be configured to operate any EV battery. This deployment represents the largest operational UL 9540-certified ESS utilizing second-life EV batteries anywhere, on any continent, showcasing B2U’s patented EV Pack Storage (EPS) technology. Sierra initiated commercial operations in 2020, with the team scaling its capacity in phases. The Sierra hybrid storage facility is interconnected directly to the grid, selling power and grid services into California’s wholesale power market, generating over $1M in revenue in 2022 alone. The project’s storage capacity is comprised of 1,300 reused EV battery packs sourced from Honda and Nissan. 07, 2023 (GLOBE NEWSWIRE) - B2U Storage Solutions, a leading provider of large-scale energy storage systems using second-life electric vehicle (EV) batteries, announced today that 25MWh of storage capacity is now operational at its SEPV Sierra hybrid solar + storage facility in Lancaster, CA.
