Private fleets of buses, delivery, municipal, and drayage vehicles. Public charging.
Demand for high-power charging and storage is growing rapidly. By 2025, 30% of bus fleets will be EVs. By the end of the decade (2030), over 40% of bus fleets will be EVs.
Between now and 2040, public transit bus fleets will grow 3x while EV school bus fleets will grow 30x.
Reliable, High-Power Energy Solutions
Preparing for high-power EVs is more than installing charging networks. From the power plant to the service station, a new ecosystem is emerging for charging and energy storage, distribution and management. The key to fulfilling our vision and seizing the high-power EV market opportunity is bringing grid-like reliability. That’s why we’re on a mission to design and build the most reliable high-power solutions for:
“Charge Only” and bidirectional “V2G” product designed specifically for continuous operation at rated loads. Can support power flow to and from the grid aligned with rapidly advancing vehicle to grid technology and allow integration with power storage and non-grid renewable power resources.
If EV charging occurs in parts of the grid that do not have sufficient capacity “head-room” to accommodate the extra power needs, distributed energy resources (DERs) solutions provide distributed generation and storage.
High-power EVs can be an electricity resource themselves, becoming a “microgrid”. Because getting electricity from a building or meter under someone else’s management can be complex, microgrids offer a way to lessen or even eliminate the complexity of fleet electrification, especially if charging will happen at existing facilities. Microgrids can also help with power availability if the distribution grid can’t accommodate those loads. You can bring in a microgrid and not need a system upgrade.
Batteries in high-power EVs can provide many of the grid services that stationary energy storage systems can provide and can also be actively managed to reduce the impacts their charging can have on the electric grid – an increasingly important capability as more and more EVs are plugged into the grid.
Uniquely Equipped to Address High-Power EV Technology
One of the rarest skills and experiences in engineering is analog power electronics. The best-of-the-best engineers designed the most resilient automotive systems and high-power grids now in use. You’ll also find them at Rhombus where they’re applying their skills, experience, and success to develop resilient systems needed by private fleets of high-power vehicles and for public charging systems for high-power vehicles.
Positioned for Success in the Future
Today, Rhombus is developing 4 technology and products for lower-cost, smaller form-factor silicon carbide-based systems, and switch-on / switch-off technology that will allow prioritization needed in efficient fleet charging systems. Rhombus is also developing advanced software that combines edge-computing, a web portal, and AI for sophisticated diagnostics and preventive maintenance.
