Product Overview
WallPod Intelligent EV Charging Unit EVWM-V01-R1 Installation and Operation Manual
Page 5of 35 December 2022
NOTE: The United Kingdom has introduced new regulations (SI 2021/1467) that apply to
domestic and private EV chargepoints, and which aligns them with other ‘Smart’
appliances.
The new regulations are, amongst other things, designed to balance demands for
power and to deliver an efficient use of power across the country whilst maintaining a
consistent and secure service to EV drivers, when and where they need it.
The regulations are an ongoing, multi-part undertaking which may bring additional
requirements in the coming months and years.
About ‘Smart’ Services
Chargepoints are to be ‘Smart’ enabled.
‘Smart’ encompasses a large number of requirements but in summary these are:
xConnected to a ‘charging application’ such as VendElectric.
xThe ability to receive remote, online software updates.
xCapable of measuring the power used and the power delivered, and the associated
time periods.
xCapable of storing and displaying data about charge sessions to the owner and/or
user, via an application and/or on the chargepoint.
xCapable of communication with the power supplier and able to adjust the delivery of
power in response to commands issued by the supplier.
xCapable of charging even in the event of communications with the network being
lost. Data recorded about the charge session will be communicated at the next
available opportunity.
xThe ability to use other charging networks (that meet the Smart requirements).
xThe ability to receive power from any electricity supplier.
xIncorporates off-peak charging as the default with the ability to override if required.
xRandomised delay between initiating a charge session and the charge session
actually starting. This is to prevent overloads of the electricity system if a large number
of chargepoints are activated the moment the off-peak period starts.
xPhysical and digital protection of data and of the components used to access that
data.
xPhysical protection of electrical components within the chargepoint to prevent
personal harm and to prevent accidental or malicious tampering.

Product Overview
EVWM-V01-R1 Installation and Operation Manual WallPod Intelligent EV Charging Unit
December 2022 Page 6of 35
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 chargepoint 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
power made available for charging can be dynamically adjusted to reduce the load
before the property’s maximum load is exceeded.
For example, if the property’s main fuse (or circuit breaker) is rated at 60 Amps, the fuse
will operate and cut all power to the property if a draw of 60 Amps is exceeded.
It can be relatively easy to draw significant power if several property appliances are in use
at the same time.
Kettle 13 A
Oven 13 A
Dishwasher 10 A
Iron 13 A
Total = 49 A
In this example, only 11 Amps remain before the 60 Amp
limit is reached.
If an electric vehicle is now put on charge and is drawing
16 Amps, the limit would be exceeded, and the property’s
fuse would operate to cut all electrical power to the
property.
With load balancing enabled, the amount of power made available for charging will, if
required, be automatically adjusted to a level that does not exceed the maximum for the
property.
The system will continue to 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.
For example, if the charger is configured by the installer for use with a property with a 60A
fuse, load balancing will start at 47Amps. Similarly, for a property with an 80A fuse, load
balancing will start at 67Amps. This allows combined use of the charger plus other
appliances in normal use with no effect on the property’s electricity. You can then use up
to 13A more, with no risk of exceeding the maximum limit and load balancing will
continue to reduce charger power if more electricity is used by other appliances.

Product Overview
WallPod Intelligent EV Charging Unit EVWM-V01-R1 Installation and Operation Manual
Page 7of 35 December 2022
NOTE: Where a Rolec Load Balancing Current Transformer (CT) has been installed and
connected to a load balancing enabled Rolec chargepoint, it will reduce the supply of
power to the vehicle where the combined demand of the property and vehicle would
exceed the power available to the property as a whole.
xOnly 1 chargepoint is to be installed per phase to avoid counteracting behaviour.
xRolec 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.
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. The lower the power available for charging, the more slowly the vehicle will be
charged.
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:
xcontrolled by the software application used either within the chargepoint or via its
online connection (or a third-party device/system).
xmore often used where there are several chargepoints at the property, and where,
depending on pre-set criteria within the software, the system will control which
chargepoints receive the most power at any given point in time.
About Demand Side Response
Similar in some ways to Load Management, a Demand Side Response (DSR) system is
where the chargepoint and the electricity provider are in communication with each
other. The electricity provider will control the chargepoint remotely via the chargepoint
software to reduce the power it draws when it is needed by higher priorities in the area
and will increase power when those priorities reduce.
If the chargepoint is used with a DSR agreement in place, peak and off-peak charging will
not be implemented because the power company’s systems will control the charging
process.
Although the power drawn (and delivered) by the chargepoint can vary, this does not
necessarily protect the property power supply from being overloaded if the demand of
the property and vehicle exceed the power available to the property as a whole.

About PEN Protection
The TruePEN system removes the need to install a dedicated earth for the chargepoint.
In the event of a fault, the system will break all power cable connections between the
chargepoint and the vehicle.
A PEN fault is most commonly seen as either, an undervoltage or an overvoltage entering
the chargepoint from the mains supply. Following initial power ON, the TruePEN system
monitors the supply voltage for 5 seconds and determines if the voltage is within normal
operating parameters. If within limits, TruePEN allows the connection of Live, Neutral and
Earth to the vehicle and continues to monitor the supply.
If the voltage goes out of limits (below 207 Volts or above 253 Volts) for a continuous
period of 5 seconds, this could be caused by a PEN fault. The TruePEN device will activate
(‘trip’) and isolate Live, Neutral and Earth to the vehicle.
xUndervoltage – Following an undervoltage trip, TruePEN continues to monitor the
supply and if the voltage returns to within limits for a continuous period of 5
seconds, the TruePEN device will automatically reset and restore the Live, Neutral
and Earth connections to the vehicle, allowing charging to resume.
xOvervoltage – An overvoltage condition is potentially more likely to damage the
vehicle so, for safety reasons, automatic recovery following an overvoltage is NOT
provided and charging cannot resume until a manual reset is performed.
Following an overvoltage condition, EV drivers are advised to investigate as far as they
can, the reasons for the overvoltage condition and to check their vehicle for correct
operation.
Occasional overvoltage conditions may simply be caused by fluctuations in the supply
but if they are frequent, the cause should be investigated by an appropriately qualified
and experienced electrical engineer and/or the electricity supply company.
Security – Tamper Protection
In conjunction with a number of the ‘Smart’ requirements, it is a requirement in the United
Kingdom that chargepoints of this type, sold after 30 December 2022, have two-levels of
anti-tamper protection. If installed…
1. Chargepoints must incorporate a boundary to guard the electrical components
from tampering whilst also providing safety to engineers.
2. The chargepoint must log and issue an alert if there is a breach or an unsuccessful
attempted breach of the boundary.
The purpose of this protection is to:
xProtect people from harm.
xProtect the chargepoint, the charging network and the electricity network from
malicious or accidental damage or abuse.
xProtect the data held on the chargepoint and/or within the associated online
applications.
