Smart Charging & the ChargeTO Pilot Slides from Webinar

  1. 1. Smart-Charging & The ChargeTO Pilot Matt Stevens, Ph.D., CEO EMC Webinar Series ChargeTO Pilot Who, What, When, ….and Why Charging Without Smart-Charging Charging With Smart-Charging 1 2 3
  2. 2. ChargeTO Driving EV Adoption CrossChasm & FleetCarma Clarification Two names - one team Enterprise Grade Connected Car Platforms Electric Vehicle Connected Car Platforms Focuses on developing best-in-world connected car technology for OEMs and technology developers Focuses on driving EV adoption by reducing purchasing barriers and improving the ownership experience A single team supports both product lines and the names are used interchangeably. Smart-charging systems fall under the FleetCarma umbrella.
  3. 3. Charging Without Smart-Charging Charging With Smart-Charging 1 2 3ChargeTO Pilot Who, What, When, ….and Why
  4. 4. ChargeTO Driving EV Adoption Funded through the Ontario Ministry of Energy’s Smart Grid Fund. The project team includes: • Ministry of Energy • Toronto Hydro • AddÉnergie Technologies • FleetCarma (aka CrossChasm) Networked EVSE partner: Who… Part 1 Project Partners
  5. 5. ChargeTO Driving EV Adoption Who… Part 2 Project Partners And the most important project partners - 30 EV Owners from Toronto Participants had to: • Own an EV & live in TH service area • Have an existing L2 EVSE installed • Be willing to have their charge controlled For participating they received: • Free Core+ AddÉnergie EVSE • Free FleetCarma EV device (myEV after) And a thank you to Plug’n Drive who assisted on the recruitment efforts. Had over 100 people register for the 30 spots.
  6. 6. ChargeTO Driving EV Adoption Now! Now! Now! Dumb Charging Scheduled Charging Smart Charging Charging begins as soon as you plug in. Charging is delayed until a preset start time or to finish at a specific end time (ie. low time-of-use rates) Charging may begin immediately but can be reduced/delayed based upon external factors. Partial control may be given to 3rd party (ie. utility or building) What… Smart-Charging Intro
  7. 7. ChargeTO Driving EV Adoption Driver Preferences Control Pathways What… How the system works AddÉnergie Back-End FleetCarma Charge Management Controller Utility Command Signal (Max Power Request) The EV owner “sets & forgets” their needs & auto-enroll criteria in the FleetCarma portal. Using the FleetCarma logger clipped in the vehicle the system can determine the needs of each EV owner. The system then automatically queues charging if the grid needs it. The system ensures the vehicle is fully charged by a specific time (TCIN). By taking the EV owner needs as the primary objective the risk to the EV owners is minimized, which results in easier recruitment of participants.
  8. 8. ChargeTO Driving EV Adoption When… Project Timing The 15-month project is split into four phases, starting in Nov 2014 and concluding in Jan 2016. The project is currently slightly ahead of schedule and under budget. As a result two additions have been made: 1. Inclusion of a variable incentive plan for an initial evaluation of incentive effectiveness. 2. Inclusion of additional reporting for CDM reimbursement (focused on accurate attribution)
  9. 9. ChargeTO Driving EV Adoption Why… Theoretical Benefits of Smart-Charging Cost Savings Revenue Opportunities Frequency Regulation Operating Reserves Reduction of GHG intensity (integration with renewables) Time of Use Rates Reduced Demand Charges Capacity Upgrade Costs (facility, distribution, or transmission) Depending on the specific electricity market and application the main cost/revenue drivers will vary.

ChargeTO Driving EV Adoption Why… Theoretical Benefits of Smart-Charging Cost Savings Revenue Opportunities Frequency Regulation Operating Reserves Reduction of GHG intensity (integration with renewables) Time of Use Rates Reduced Demand Charges Capacity Upgrade Costs (facility, distribution, or transmission) Depending on the specific electricity market and application the main cost/revenue drivers will vary. Ex. Residential charging in a market with nearly 100% hydro (ie. Residential charging in Quebec)

ChargeTO Driving EV Adoption Why… Theoretical Benefits of Smart-Charging Cost Savings Revenue Opportunities Frequency Regulation Operating Reserves Reduction of GHG intensity (integration with renewables) Time of Use Rates Reduced Demand Charges Capacity Upgrade Costs (facility, distribution, or transmission) Depending on the specific electricity market and application the main cost/revenue drivers will vary. Ex. Workplace charging in a market with nearly 100% hydro (ie. Workplace charging in BC)

ChargeTO Driving EV Adoption Why… Theoretical Benefits of Smart-Charging Cost Savings Time of Use Rates Reduced Demand Charges Capacity Upgrade Costs (facility, distribution, or transmission) Depending on the specific electricity market and application the main cost/revenue drivers will vary. Ex. Workplace charging in a market with nuclear power, renewables, and GHG cap & trade being introduced (ie. Workplace charging in Ontario) Revenue Opportunities Frequency Regulation Operating Reserves Reduction of GHG intensity (integration with renewables)
  13. 13. ChargeTO Driving EV Adoption And what we are hearing from fleets “We are interested in smart charging because demand charges are starting to make the EV ROI difficult” ~ US private company “At some point we will not be able to install a charging station for every EV we add to the fleet” ~ Canadian municipality “Adding 20 more EVs will cost us $150K in service upgrade costs” ~ US municipality
  14. 14. ChargeTO Driving EV Adoption Why… ChargeTO (this pilot) All of the theoretical benefits of smart-charging rely on one assumption… That EV owners will permit reasonable access to their charging. Strong work has been done to track what EV and potential EV owners say they would be willing to do. -- ChargeTO seeks to answer the following questions with real EV owners that are actually being curtailed: 1. How comfortable are EV owners with controlled charging in the FleetCarma system? 2. What is the average kW/vehicle of curtailment capacity that is available to the utility (per hr of day)? 3. How does the average kW/vehicle of curtailment capacity vary by EV owner type? 4. What is the $ of curtailment value per vehicle? 5. How does the $ of curtailment value per vehicle vary by EV owner type?

Baseline charge behaviour (immediate/delayed) vary by owner 4. Baseline charge behaviour varies by day 5. Baseline charge behaviour varies by model Also, assuming the participants’ actual charging behaviour is representative of all Toronto EV owners: 1. Current charging load in Toronto peaks at ~1MW. 2. Charging load has multiple peaks. The most prominent one varies by month (ie. ~7:30pm for Feb). 3. Charging load in Toronto is predicted to rise to 16MW in under four years.

  25. 25. ChargeTO Driving EV Adoption Smart-Charging EV Owner View/Preferences The EV owner view is responsive so that it is easily viewed on a mobile devices. There are three “knobs” for the EV owners to turn. This will be described in detail on the next slide.
  26. 26. ChargeTO Driving EV Adoption Smart-Charging EV Owner View/Preferences The EV Owner expresses their needs/interests in the following three steps: 1. Only consider me for curtailment if my SOC is above… 2. And you can have me fully charged by… 3. And I haven’t hit the 24hr opt-out button. So… If I’m above the min-SOC, and you can have me fully charged by when I need, and I haven’t hit the 24hr opt-out, then I’m available for curtailment.

  34. 34. ChargeTO Driving EV Adoption 100 ChargeTO The Four Most Important Results to Date days of active curtailment reports of “the system curtailed me & I wasn’t fully charged on time” (a few EVSE installation issues though…) 0 reduction in daily peak charging load. This is the % of peak load that can be shed every night. 51% 85% temporary reduction in peak charging load This is load that can be shed for a temporary period (<1hr) Extrapolating to the June 2019 values this would represent an active daily management curtailable load of 10MW, with the ability to curtail up to 14MW for periods of up to an hour.
