onsemi has announced the availability of nine new EliteSiC Power Integrated Modules (PIMs) enabling bidirectional charging capabilities for DC ultra-fast electric vehicle (EV) chargers and energy storage systems (ESS).
The silicon carbide-based solutions will dramatically improve system cost with higher efficiency and simpler cooling mechanisms that can reduce size by up to 40% and weight by up to 52% compared to traditional silicon-based IGBT solutions. With more compact, lighter charging platforms, designers will have all the key building blocks that are needed to quickly deploy a reliable, efficient and scalable network of DC fast chargers that can charge electric vehicle batteries up to 80% in as little as 15 minutes.
According to J.D. Power’s 2023 Electric Vehicle Consideration Study, nearly half of U.S. consumers note the reason for not purchasing an electric vehicle is the access to charging and the ability to do so quickly, to ensure the driving experience is as easy and seamless as with a traditional internal combustion engine (ICE) vehicle. In the U.S., the availability of EV chargers needs to quadruple by 2025 and 8x by the end of the decade to keep up with demand[1] and ensure drivers have equitable access to public charging stations.
In turn, this rapid increase in demand for electricity will also put a tremendous strain on current electrical grids, potentially overloading them. To mitigate this problem, bidirectional charging has emerged as a key solution to implement vehicle-to-grid which allows both regular battery charging and the ability to use an EV as an energy storage system to power your home when needed.
onsemi offers the most comprehensive portfolio of PIMs to address the key topologies on the market. This gives designers the flexibility to pick the right PIM for power conversion stages in their DC fast charging or energy storage system applications. To accelerate the design cycle, advanced piecewise linear electrical circuit simulation (PLECS) models through our Self-Service PLECS model Generator and application simulation with the Elite Power Simulator of this portfolio will also be made available to designers.
