Reachable Controls: Screens, Buttons & Payment

A charger should be usable without stretching, twisting, or leaning over obstacles. All operable parts — screens, payment terminals, RFID readers, and connector holsters — should be within a comfortable reach range.

Mounting height matters — too high is a barrier for seated users; too low creates strain for taller users
Forward reach over obstacles is hardest — reaching over a curb or bollard significantly reduces comfortable reach
Side reach is generally easier and safer — charger placement should favour side access where possible
Payment terminals and RFID readers must meet the same height standards as screens

A person in a wheelchair has a smaller comfortable reach envelope than a standing person — especially forward reach over an obstacle. What feels like a minor inconvenience when standing can be completely out of reach from a seated position.

Charger screen and controls — reach and height

A side-by-side or annotated image showing a charger screen at an accessible height vs. one mounted too high or requiring forward reach over an obstacle. Ideally shows a person (standing or seated) actually reaching for the screen — demonstrating what comfortable reach looks like vs. an awkward stretch. A simple annotated diagram would also work if photography isn't available.

Dimensions drawn from CSA/ASC B651:23, CSA/ASC B651.2, and U.S. Access Board EV charging guidance. Always verify current requirements against the applicable standard in your jurisdiction.

Operable Parts — Mounting Height

Acceptable height range for all operable parts (screens, payment terminals, RFID readers, connector holsters): 400 mm–1200 mm (16″–47″) above finished floor — CSA B651:23 §4.2.3
U.S. equivalent (ADA §308): 380 mm–1220 mm (15″–48″)
Recommended screen viewing height: minimum 1015 mm (40″) — U.S. Access Board EV Proposed Rule, 2024
Controls should be angled for use from both seated and standing positions — CSA B651.2

Clear Floor or Ground Space

Minimum clear space beside charger for side approach: 800 mm × 1350 mm (32″ × 53″) — CSA B651:23 §4.2.2
For both forward and side approach: 1350 mm × 1350 mm (53″ × 53″) — CSA B651:23

Reach Range

Maximum unobstructed side reach: 1200 mm (47″) above floor — CSA B651:23
Maximum forward reach over obstruction: where obstruction is no more than 635 mm (25″) deep, maximum reach height is 1220 mm (48″) — ADA §308
Side reach is preferred over forward reach wherever possible — U.S. Access Board EV Technical Assistance Document, 2022

Operable Parts — Force and Operation

Maximum operating force: 22 N (approximately 5 lbs) — CSA B651:23 §4.2.4
Must be operable with one hand, without tight grasping, pinching, or twisting of the wrist — CSA B651:23 §4.2.4
Controls should be operable by persons wearing standard winter gloves — U.S. Access Board EV Technical Assistance Document, 2022 (recommendation)

Screen Accessibility

Audio output and tactile indication required in addition to visual cues — CSA B651.2
High-contrast display: minimum 3:1 luminance contrast ratio recommended — CSA B651:23
