Add extra capacity if electrical panels are being upgraded now.
l
Use sub-panels as a way to shorten electrical paths.
l
Maximise the conduit and conductor sizes (to product specifications) between the main electrical
l
panel and future stations, to prevent needing to re-pull wire later.
Below-ground wiring can be pre-staged if the correct site construction is performed in advance.
l
Allowed terminations include a distribution unit, junction box or plugged conduit. This eases cable
pulls for future stations.
Charging Station Placement
To minimise costs, choose station locations that are as close as possible to the available electrical
infrastructure. Selecting nearby locations helps minimise long wire runs, as well as any conduit or trenching
work if the site uses underground service wiring.
WARNING: Power Blocks and Power Links must be installed on a surface rated for the weight of
the enclosure (a level concrete base for either Power Block or Power Link or a flat wall or gantry
for Power Link). Tarmac cannot support the full weight of the station. Failure to install the
enclosure on a suitable surface may cause it to tip over, resulting in death, personal injury or
property damage.
Layout considerations:
Determine appropriate ground anchoring locations where concrete exists or can be installed (no
l
asphalt surfaces).
Consider locations where it will be easy to add future stations.
l
Determine the best conduit layout to minimise linear conduit costs to multiple parking spaces. If
l
possible, avoid or minimise trenching requirements, especially more costly trenching to run conduit
under asphalt surfaces.
Determine if the existing utility service and electrical panel capacity is sufficient. Identify costs for
l
any necessary upgrades and/or a new dedicated electrical panel. ChargePoint recommends using a
certified electrician to evaluate available capacity and identify any upgrades that may be required.
If a dedicated EV electrical panel is required, choose a panel located close to the existing electrical
l
supply.
Measure mobile signal levels to ensure adequate mobile coverage at the station locations. To ensure
l
adequate signal strength in underground or enclosed parking structures, mobile repeaters may be
required. For more information, see Connectivity.
ChargePoint recommends avoiding locations under trees where sap, pollen or leaves would fall on
l
the charging station and increase the station owner's site maintenance workload.
