Typical EV Charging Use Cases for Federal Fleet Vehicles

Joseph Gottlieb, CTO, Tuesday November 2, 2021

Another interesting case when considering vehicle electrification and charging for the US Government Fleet. This fleet (also known as the “federal vehicle fleet”) is one of the largest “single-owner” fleets in the US, if not in the world. The federal vehicle fleet has a total of 645,000 vehicles, including 225,000 US Postal Service (USPS) vehicles. Among other things, this fleet has about 200,000 passenger cars, nearly 79,000 heavy-duty trucks and over 47,000 vans. Electrifying this fleet is one of the centerpieces of President Biden’s green environmental/economic growth initiative, and one of the critical considerations of this initiative is the use of US-produced vehicles and charging equipment.

With a fleet this varied, one could imagine that the charging infrastructure problem for these vehicles would be complex, but the key is in the mix of who operates what. Nearly 60% of the passenger vehicles are operated by civilian agencies (DoJ, DoT, DoE, DHS, etc.), which tend to be positioned at or near office buildings. The charging use cases for these vehicles generally is very similar to that for privately-owned light duty-vehicles (see our previous blog on this topic), and can be adequately serviced by commercial mixed-use AC chargers. Of the trucks in the federal vehicle fleet, nearly 50% are operated by the US Postal Service, 25% by military agencies, and the remaining 25% by a handful of civilian agencies. Generally, these vehicles are fairly concentrated in fleet vehicle yards, with charging use cases similar to those of comparable civilian fleet vehicles (you can read our blogs on delivery vehicles and buses on the Rhombus website).

And if you are looking for made in the USA high-power DC fast charging systems for those EVs, look to Rhombus Energy Solutions. Rhombus will be at the Government Fleet Expo (GFX) Show in mid-November – reach out to us if you would like to meet with us there. Our market-leading bi-directional EV charging systems (which are designed from the start for the needs of fleet operators) are designed and built in the USA. Rhombus also excel in the design of high-power smart inverters for next-generation renewable energy and energy storage deployments. Our expertise in energy management system (EMS) software is also embedded in our VectorStat EMS controller and software which is embedded in our EV charging systems and smart inverters. We have built over a thousand V2G-capable high-power, high-reliability chargers and bi-directional smart inverters for a variety of different sizes and classes of EVs.
