Fleet Electric Vehicle Charging Scenarios

(Joseph Gottlieb, CTO, Thursday, April 23, 2020)

For fleet operators with electric vehicles (EVs), the availability of adequate energy resources for charging are critical. If the EVs can’t be adequately charged, they can’t support the fleet operator’s needs. There are several scenarios how fleet operators charge their EVs:

  • Using public charging infrastructure: For smaller fleet operators, this caallyan be an attractive option, especially if there are chargers nearby. However, this approach has several shortcomings, including charger unavailability (being used by others) and higher energy costs. Also, many charging network operators (Tesla for instance) do not allow fleet or ridesharing operators to utilize their charging networks.
  • Deploy their own charging infrastructure: This option is much more common, especially for fleet operators with a “vehicle yard” where they park their vehicles, such as rental car companies, public and school bus operators, and municipal vehicle fleets. In mnay cases, these operators will also deploy solar photovoltaic (PV) panels in their yard, putting this power back onto the grid to reduce their energy costs. Most operators are now also utilizing vehicle-to-grid (V2G) charging to put the remaining power from their buses back onto the grid during peak hours.

The Los Angele Metropoitan Transit Authority (MTA) has 2,472 buses (2nd largest fleet in North America) with 13 bus yards (avg of 190 buses/yard). First Student, the largest school bus operator in the US, has a fleet of 44,000 vehicles across 39 states and 1,100 school districts (an average of 40 buses/district).

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 vehicle-to-grid (V2G) charging. Our VectorStat® hardware and software allows fleet customers to gather data from all of their infrastructure  nodes, regardless of connectivity or network issues, to effectively manage their energy resources. VectorStat’s applet-based open architecture also enables the easy integration of new features and functionality, whether to support new hardware or to provide cutting-edge data analytics capabilities.
