Quantum Intelligent EV Charging Pedestal EVQM-V01-R6 Installation and Operation Manual
Page 5 of 52 December 2023
NOTE: When detailing Load Balancing and Load Management, this manual assumes the
installation of a single chargepoint. Whilst multiple chargepoints can be connected in a
similar way, installers may wish to consider connecting/monitoring using a third-party,
compliant energy management solution.
If connecting/monitoring via third-party equipment, make sure you are fully aware of
the manufacturer’s instructions so that the device/system can be installed correctly and
in conjunction with the pedestal installation.
About Load Balancing
This chargepoint has a Load Balancing capability which is designed to prevent overloads
of the property’s power supply when a vehicle is being charged. This is similar in some
ways to Load Management but is NOT the same. Refer to the next page to read about
Load Management.
Once correctly installed and configured, the system will monitor the power being drawn
by the charging process and will compare this to the permissible maximum for the
property as a whole (which is set as part of the configuration). With this information, the
system will monitor the power and will dynamically increase and decrease the power
made available for charging in response to the demand for power from the rest of the
property.
Rolec chargepoints are pre-configured to load balance with a 13A ‘buffer’. This means
that whatever the property fuse may be, load balancing will start 13A before its maximum
limit is reached.
NOTES:
1. Load balancing ONLY controls power made available to the VEHICLE. It does not
control power to other equipment, and it is still possible for that equipment to
overload the property’s power supply.
2. Depending on the manufacturer, electric vehicles need a minimum of around
6 Amps to charge. If the available power is below this level, the vehicle may stop
the charge session.
3. Only 1 chargepoint is to be installed per phase to avoid counteracting
behaviour.
4. Rolec cannot be held responsible for overloads of the supply caused by other
connected electrical items or failure of the vehicle to accept a reduced rate of
charge.
About Load Management
This chargepoint is capable of Load Management. This is similar to load balancing in that
the power made available for charging can be dynamically adjusted to decrease or
increase the power available in response to other demands for power at the property.
The significant differences are that Load Management is:
x controlled by the software application used either within the chargepoint or via its
online connection (or a third-party device/system).
x more often used where there are several chargepoints at the property, and where,
the system will control which chargepoints receive the most power.
