Bi-Directional Electric Vehicle Charging Solution – Digital Nova Scotia – Leading Digital Industry

Bi-Directional Electric Vehicle Charging Solution

Public Services and Procurement Canada (PSPC) is seeking an innovative Electric Vehicle (EV) charging solution that promotes increased adoption of electric vehicles while using bidirectional energy to aide in the decarbonization of Real Property buildings.

Problem statement

The electrification of the transportation sector underway in the Government of Canada leads PSPC to look ahead for smart and innovative vehicle charging technologies that will support the transition and decarbonization of its portfolio of buildings.

One of the main challenges for PSPC, is the increased electrical load of its current infrastructure due to the increased electrification of heating. The electrification of heating is a significant part of the decarbonization strategy for Federal operations. PSPC is committed to the reduction of greenhouse gas (GHG) emissions by way of various means – inclusive of vehicle fleet emissions.

The electrification of the vehicle fleet will add to the increased electrical load of building operations. EV charging is an electrical load that is considered flexible, and can be modulated based on factors such as the building’s power draw from the electrical grid.
In addition, the electric battery of a vehicle could be leveraged as an energy storage device to support the building’s effort to reduce its peak electrical demand on the electricity grid by employing Vehicle to Grid (V2G) and/or vehicle to Home/Business (V2H) technologies.

As V2G technology roles out, a concern is the lack of a standard bi-directional EV charging protocols as well as the lack of standard/compatible charging connectors. Currently, only a handful of EVs support V2G and bidirectional DC charging, and only a few EVs currently feature V2H technology.

Desired outcomes and considerations

Essential (mandatory) outcomes

The proposed solution must:

  • Provide a charging infrastructure with Level II (240v, 40A) universal charging capability.
  • Provide a charging infrastructure that is bi-directional energy capable (e.g. be able to supply power to vehicles’ batteries and draw power from vehicles’ batteries)
  • Be able to supply continuous variable energy
  • Integrate a real-time capacity, such as but not limited to, an artificial intelligence adjustment of power supplied to and from connected vehicles, based on real-time building power demand allowance.
  • Be able to provide real-time analytics such as the flow of energy, the consumption of energy, and real-time projections to users of the solution.
  • Have a charging infrastructure (hardware) that supports future firmware/software development toward advanced bi-directional energy exchange functions.

Additional outcomes

The proposed solution should:

  • Have technology that allow user participation options (For example: ability to choose between unidirectional or bi-directional power flow)
  • Demonstrate the potential for scalability of infrastructure and how it supports transition toward a heavily electrified vehicle fleet.

Background and context

The electrification of vehicles and the addition of charging infrastructure will lead to an increase in electricity consumed by PSPC’s building portfolio. It is expected that, in combination with the electrification of space heating to reduce greenhouse gas emissions, the building’s peak electrical demand profile will increase and change over time. This will present a challenge to the existing electrical infrastructure, and could lead to costly capital upgrades and operational charges. There is an opportunity to leverage EVs as active components of the decarbonization of real property operations.
