Product Components
Several components comprise a full Express Plus installation:
Power Module: A scalable module that contains power conversion electronics.
l
Power Block: An enclosure that holds up to five Power Modules and provides them with a liquid
l
cooling system. The Power Block centralises power conversion that supplies DC power to Power Link
2000s.
Power Link 2000: A charging station that can be mounted on a pedestal, on a wall or overhead. Each
l
Power Link 2000 is provided with isolation monitoring and short circuit protection to ensure safe
operation.
Power Hub: A distribution cabinet used in fleet charging architectures to connect a few Power
l
Blocks to many Power Link 2000s.
The Express Plus solution is highly modular. Each Power Block has two DC outputs. That power can be fed
to a single station, or to two different stations, depending on configuration. Low voltage and Ethernet
connectivity are also fed to either one or two stations. If a Power Hub is used, the number of connected
stations can be increased to eight, two or four of which can actively charge at a time, depending on the
configuration.
Note: For projects that include Power Hubs, see the Express Plus Power Hub Site Design Guide.
Initial Site Guidelines
An on-site evaluation is needed to determine conduit and wiring requirements from the panel to the
proposed parking spaces, as well as to measure mobile signal levels and identify suitable locations for any
necessary mobile signal booster equipment.
If you have pre-existing infrastructure or are using your own preferred electrical contractor to prepare your
site, a Power Link 2000 Construction Signoff Form completed by a ChargePoint Operations and
Maintenance (O&M) partner is required to certify compliance with electrical code, and to ensure everything
was prepared to ChargePoint specifications.
IMPORTANT: You must be a licensed electrician and complete online training to become a
ChargePoint certified installer. If you do not complete this training, you cannot access the
ChargePoint network to complete the installation.

If the charging station is not installed by a ChargePoint-certified installer, using a ChargePoint-
approved method, it is not covered under warranty and ChargePoint is not responsible for any
malfunctions.
Plan for Future Charging Capacity
Designing electrical infrastructure to support current and future needs for EV charging helps avoid costly
upgrades later as demand for EV charging grows.
Consider these methods to prepare a site for future charging stations in a later phase of work:
