Imagen Energy has developed a highly compact integrated modular inverter/energy storage system to revolutionize deployment of energy storage system for grid, micro-grid, energy efficiency, and energy reliability support. The firmis working on an advanced energy storage system consisting of an extremely compact 150kW high frequency 3-Level inverter, an integrated 48kWhr compact Li-ion battery system, proprietary battery management systems and internet communications capability. The objective is to provide a highly integrated and scalable 150kW Energy Storage System with an integrated battery string inverter with 60% reduced system cost and 10X reduced size that open new markets for energy storage and renewable energy. Involving the development of key technology innovations that will work together with advanced Li-ion batteries to form a revolutionary new product, innovations include: high frequency 3-level inverter with innovative high frequency control and output filter to achieve >10X reduction in volume; a novel topology that integrates inverters into each cell string and eliminates many components resulting in 60% system cost reduction; a modular and scalable design that is fault-tolerant and allows easy optimization for multiple system uses. In November 2022, it was announced that Department of Energy (DOE) would allocate $100 million to fund eight clean energy technology projects to lower emissions through clean energy deployment, reduce dependence on imports of critical minerals, and secure the nations standing as a global leader of research and innovation. ImagenEnergy was in receipt of $12M of that funding to scale up and commercially demonstrate efficient, cost-effective U.S.-manufactured EV fast charging equipment. The compact EV fast charger will optimize limited grid power availability at public and fleet charging locations to enable resilience and flexibility and is ideal for urban communities that otherwise lack investment opportunities to deliver the benefits of EVs.
