Smart Columbus Overview: Electric Vehicle Supply Equipment Three primary types of Electric Vehicle Supply Equipment (EVSE) • AC Level 1 • AC Level 2 • DC Fast Charging AC Levels 1 and 2 • Alternating current is provided to the vehicle’s onboard charger, which converts the electricity to the direct current required to charge batteries • J1772 charging connector • Tesla – proprietary connector DC Fast charging • Provides direct current immediately to the vehicle’s battery. • CCS Combo standard or the Chademo standard • Tesla offers adapters
The table below provides an overview of EVSE charging times and supply power. Charging Level Vehicle Range Added per Supply Power Applicable Connector(s) Charging Time and Power Level 1 4 mi/hour @ 1.4kW 120VAC/20A J1772 6 mi/hour @ 1.9kW (12-16A continuous) Tesla Level 2 10 mi/hour @ 3.4kW 208/240VAC/20-100A J1772 20 mi/hour @ 6.6kW (16-80A continuous) Tesla 60 mi/hour @ 19.2 kW DC Fast Charging 24mi/20 minutes @ 24kw 208/240VAC 3-phase Chademo (input current proportional 50mi/20 minutes @50kW CCS Combo to 90mi/20 minutes @ 90kW Tesla Supercharger output power; ~20-400A AC)
EVSE Equipment Wall Mounted & Pedestal Mounted • $500-700 more for Pedestal Mounted Single port EVSE units • Provide charging for one vehicle at a time, and are cheaper than EVSE units with multiple ports • Unit cost and the installation cost are less expensive on a per-port basis for multiple port units Networked Unit • Connected to the internet through a cable or wireless technology • Options to add an aftermarket module to a non-networked EVSE that enables it with various networked capabilities. • Without EVSE, some electric vehicles do have some networking capabilities through onboard software
Networked EVSE Networked, or “Smart” charging technology, provides the ability to access the EVSE remotely at any time for utilization of the following features, in descending order of technological advancement: Authentication/Access • Basic lock and key entry • Digital Access Features: Site host can require Passcode or credentials o Users must connect through their Smartphone via bluetooth or WiFi o • Digital access through network: RFID o Can require Vendor / organization card o Access through Mobile app o Marketing/Educational Capabilities: • Site owner can promote their company or educate around EVSE usage through videos and advertisements either in mobile app or on EVSE equipment screen, enabling revenue stream from advertisement
Networked EVSE Data access for host: • Standalone units can monitor voltage and current of one or more EVSE units • Manual (in-person download) or automatic (web/network publishing) data availability around EVSE usage • Metering capability to track energy usage- can be per-unit or common to a bank of units Data interaction with guest: • EVSE provides guests with near real-time data availability from charger, typically accessible via mobile app • May allow consumer to set preferences on rate of charge, completion time, pricing response etc. Load Management: • Local network connectivity allows building management to control power output of the system • Can be used to optimize electrical infrastructure among a group of EVSE • Could roll up to a building demand response program
Networked EVSE Billing: The site owner/operator can recoup costs through: • Point of sale RFID o Vendor/organization card o Credit card reader o • Mobile app integration Vendor / organization / utility based billing integration o Paid access to a regional EVSE network (such as Chargepoint or Greenlots) o Grid integrated demand response: • Energy Monitoring and Management • EVSE responds to regional and local grid needs and constraints as appropriate / configured • Demand response can be structured through pricing tiers or utility driven equipment loading
Networking Modules There is also the option to add an aftermarket module to a non-networked EVSE that enables it with -various networked capabilities, including: • Control over Authentication/Access • Load control and metering • Data Capture These aftermarket modules allow for site hosts to purchase cheaper non-networked EVSE and later upgrade their capabilities. See image below for an example:
EVSE Costs and Considerations Cost factor variations for installation: • Distance between the unit and the electrical access point • Whether the installation is a new build or retrofit • Whether trenching is required • Whether or not the electrical service provides the following: A dedicated circuit for each EVSE unit on the electrical panel (in most cases). o Sufficient electrical capacity from the utility connection to the electrical panel. o Sufficient electrical capacity at the panel. o The below diagram shows an example of cost increasing with features.
EVSE Costs and Considerations EVSE Type Installation Cost Range (per EVSE Unit Cost Range O&M Cost* unit) (single port) Level 1 $0-$3,000 $300-$1,500 -Maintenance: $100-300 lifetime Source: US DOE 2016 Report -Network fees: $100-900 annually Level 2 $600-$12,700 $400-$6,500 -Maintenance: $300 lifetime Source: EV Project, INL -Network fees: $100-900 (Networked Units cost up to annually 6,500) DCFC $4,000-$51,000 $10,000-$40,000 -Maintenance: $1,000-2,000 annually Source: EV Project, INL -Network fees: $100-900 annually *Operation and Maintenance costs varies significantly based on equipment and features. Regular maintenance is not required for basic Level 1 and 2 EVSE units.
