ChargePoint Express 280 - Plan for Future Charging Capacity; Charging Station Placement

If you have pre-existing infrastructure or are using your own preferred electrical contractor to prepare your
site, you must complete a Construction Signoff Form to certify compliance with electrical specification
requirements and to ensure everything was prepared to ChargePoint specifications.
IMPORTANT: Always check local codes or consult an engineer to ensure the site is prepared in
compliance with all applicable regulations. Local authorities might not allow a unit to operate if it
is not installed to code.
Plan for Future Charging Capacity
ChargePoint recommends planning to install charging stations for 5-10% of parking spaces, or 10-15% for
high electric vehicle (EV) adoption areas like California. Designing electrical infrastructure to support
current and future needs for EV charging helps avoid costly modifications later as demand for EV charging
grows.
Consider these methods to prepare a site for future charging stations in a later phase of work:
l
Add extra capacity if electrical panels are being upgraded now
l
Use sub-panels as a way to shorten electrical paths
l
Oversize the conduit between the main electrical panel and future stations
l
Install pull or junction boxes at the end of an existing row of charging stations, to ease cable pulls for
future stations
l
If a junction box or disconnect will be installed between rows of stations, oversize the wiring
between the main panel and the junction box to prevent needing to re-pull wire later
Charging Station Placement
To help minimize costs, choose station locations that are as close as possible to the available electrical
infrastructure. Selecting these types of locations helps minimize long conduit and wire runs, as well as any
trenching work.
WARNING: The charging station must be installed on a level concrete base. Asphalt cannot
support the full weight of the charging station. Failure to install on a level concrete base may
cause the station to tip over, resulting in death, personal injury, or property damage.
Layout considerations:
l
Determine appropriate ground anchoring locations where concrete exists or can be installed (no
asphalt surfaces).
l
Consider locations where it will be easy to add future stations.
l
Determine the best conduit layout to minimize linear conduit costs to multiple parking spaces. If
possible, avoid or minimize trenching requirements, especially more costly trenching to run conduit
under asphalt surfaces.
