Why Rhombus Chargers Are Different

(Rick Sander, CEO, Tuesday, June 16, 2020)

Our last couple of blogs explored the impact of reliability on fleet electric vehicle (EV) charging systems, and how thermal design is critical to building high-reliability EV chargers. But like with most products development activities, designing and building successful products is driven by the goals and overall philosophy of the organization designing and building the products. This is one of the greatest differentiators of Rhombus Energy Solutions fleet EV charging systems – our goal and focus is to build chargers with the highest reliability and performance, and which meet or exceed the requirements of our fleet vehicle customers.

A good example of this focus on meeting the requirements of fleet EV customers is how we approach design-for-cost of our systems. Most companies approach design-for-cost through the purchase of the lowest-cost components, minimizing the number of subsystems, and utilizing low-cost enclosures. While this is a reasonable approach for “throwaway” products, for high-power fleet EV chargers this approach can have a negative impact on maintainability. A similar case can be made for adding “future features” (also known as future-proofing) – it increases the cost of a system in the short-term, but reduces the total cost of ownership (TCO). These are all factors that Rhombus considers in the design and manufacture of our products. When we design to cost, we focus on the most efficient manufacturing processes and product architectures. This is also why our chargers all incorporate vehicle-to-grid (V2G) charging as a capability. The result are chargers that fleet EV operators’ requirements, have extremely high reliability, are inherently maintainable, and meet the requirements for both today and tomorrow.

As a leader in the development and manufacturing of bi-directional, high-power energy systems for both vehicle charging and photovoltaic solar applications, Rhombus is an expert in high-power charging systems for EVs, and especially in the area of V2G charging. We have built hundreds of V2G-capable high-power, high-reliability chargers for a variety of different sizes and classes of EVs.
