EVITP User Experience and Accessibility 2 — Questions and Answers
Question 1: Under ADA guidelines, what is the maximum height for operable parts (buttons, card readers) on an EV charging station serving accessible spaces?
- 54 inches above the floor
- 48 inches above the floor (Correct answer)
- 60 inches above the floor
- 42 inches above the floor
Correct answer: 48 inches above the floor
ADA requires operable parts to be no higher than 48 inches above the finished floor to be reachable from a wheelchair.
Question 2: What minimum width of accessible route must be maintained from the parking stall to an EV charging station under ADA standards?
- 36 inches (Correct answer)
- 30 inches
- 42 inches
- 48 inches
Correct answer: 36 inches
ADA requires a continuous accessible route of at least 36 inches wide connecting accessible parking to the charging equipment.
Question 3: An EV charging station cable is too short for a user in an accessible stall to reach the vehicle charge port. Which EVITP-aligned corrective measure is most appropriate?
- Install a cable rated for at least 25 feet
- Reposition the EVSE unit closer to the stall boundary (Correct answer)
- Require users to repark their vehicles
- Add a cable extension adapter in the station kit
Correct answer: Reposition the EVSE unit closer to the stall boundary
Repositioning the EVSE closer to the accessible stall boundary ensures the cable can reach without requiring the user to stretch or repark.
Question 4: Which surface condition beneath and around an EV charging station is required to meet ADA accessibility standards?
- Compacted gravel with drainage slope
- Firm, stable, and slip-resistant surface (Correct answer)
- Painted asphalt with textured strips
- Rubberized mat over existing pavement
Correct answer: Firm, stable, and slip-resistant surface
ADA mandates that accessible surfaces be firm, stable, and slip-resistant to support wheelchairs and other mobility devices.
Question 5: When a Level 2 EVSE is installed in a parking facility with 50 total spaces, how many of the EVSE units must serve ADA-accessible parking spaces per current DOJ guidance?
- At least one per every 25 chargers installed
- At least one accessible EVSE for every accessible parking space provided (Correct answer)
- A minimum of two accessible EVSE units regardless of total count
- One accessible EVSE for the entire facility
Correct answer: At least one accessible EVSE for every accessible parking space provided
DOJ guidance recommends that each accessible EV parking space be served by an accessible EVSE, mirroring the accessible space count.
Question 6: What is the purpose of an 'accessible aisle' adjacent to an EV charging parking space?
- To store charging cables when not in use
- To provide space for wheelchair transfer and mobility device maneuvering (Correct answer)
- To mark the boundary of the charging zone for fire code
- To create a buffer between EV and non-EV vehicles
Correct answer: To provide space for wheelchair transfer and mobility device maneuvering
An accessible aisle (typically 60 inches wide for van spaces) allows wheelchair users to exit the vehicle and maneuver to the EVSE.
Question 7: Which tactile feature is recommended on or near an EV charging station to assist visually impaired users in locating the unit?
- Brightly colored paint on the EVSE housing only
- Tactile detectable warning strips leading from the curb to the unit (Correct answer)
- A flashing strobe light on top of the unit
- Raised letter signage above eye level
Correct answer: Tactile detectable warning strips leading from the curb to the unit
Detectable warning strips provide tactile ground-surface cues that guide visually impaired users safely to the charging station.
