l
Use dual-port pedestal mount stations where possible in open areas for adjacent parking or
adjoining parking spaces.
l
Consider protective bollards and wheel blocks where appropriate, especially for open tandem
parking spaces.
l
If the charging station has a camera, orient the camera towards the parking space.
l
Use professional cellular test equipment to measure cellular signal levels to ensure adequate cellular
coverage at the station installation location. To ensure adequate signal strength in underground or
enclosed parking structures, cellular repeaters may be required. Use an indoor antenna located near
EV parking spaces and an outdoor antenna typically located at the garage entrance ceiling or on the
rooftop where cellular signals are best. See Connectivity for more details.
l
When the charging stations cannot be placed close enough to the source of power to avoid
undesirable line losses, consider increasing the size of the conductors. When the circuit conductors
must be larger than 1/0 AWG, you must add a disconnect immediately adjacent to the station and
terminate the upsized conductor at the line side lug of the disconnect. Then, connect a short length
of 1/0 AWG conductor to the load side lug of the disconnect and the station. Adding disconnects
close to the stations is also helpful when the circuit breakers are relatively far away.
Plan for the Future
Consider current EV charging needs and also potential future needs as EV adoption grows.
l
Consider running raceway or conduit to all planned EV parking spots and pulling electrical wiring
from the panel to meet current needs.
l
Consider installing a dedicated electrical panel for EV charging and leveraging ChargePoint Power
Management. This efficiently uses available power at a site to support more EV charging ports than
would otherwise be possible.
