Smart Functionality

Operating manual| Technical solution adopted to meet the requirement
---|---
Charge point is able to send and receive information via a communications network| The charge point has the following built-in network interfaces:

•        Ethernet (LAN)

•        Wi-Fi

•        GSM

Using any of these network interfaces, the charge point can connect to a communications network and is able to receive and send information via the communications network.

The owner can connect to the charge point’s web interface via LAN or Wi-Fi (which doesn’t require an Internet connection) to configure the preferred network interface that should be used to connect to then Internet.

Charge point is able to respond to signals or other information received by it by:

•       Increasing or decreasing the rate of electricity flowing through the charge point

•       Changing the time at which electricity flows through the charge point

| The charge point supports the OCPP (Open Charge Point Protocol) for communication with a central system, also referred to as charge point management system or CPMS. Via OCPP the charge point can be instructed to:

•        increase or decrease the electricity flowing through the charge point;

•        change the time at which electricity flows through the charge point.

Whenever such information is received by the charge point, it would accordingly increase or decrease the electricity flowing through the charge point or change the time at which electricity flows through the charge point, within the built-in limitations ensuring safe operation of the charge point.

Charge point is capable of using this functionality to provide demand side response services, including response DSR services.| The charge point can use the functionality described above to provide demand side response services, including response DSR services.

By default, the charge point is configured to connect to the SyncEV charge point management system (CPMS) via OCPP.

The charge point can be reconfigured by the owner to connect to another cloud system via OCPP, including a DSR service, and is capable providing demand side

response services as per the information received from such cloud service that the charge point is connected to

Furthermore, the SyncEV CPMS – which the charge point is connected by default, is integrated with several flexible electricity tariffs, such as Agile Octopus and Octopus Go and can be integrated with other tariffs as they become available.

Whenever the owner of the charge point is on any of the supported flexible tariffs, the owner can choose to schedule charging based on the flexible electricity tariff. While this is just one way to integrate with DSR services, this illustrates the capability of the charger to provide demand side response services, including DSR services.

---|---
Charge point has at least one user interface, incorporated in the charge point or otherwise made available to the owner| The charge point has the following interfaces that are available to the owner or a relevant person:

•        A web interface for initial setup and basic power management, which can be accessed even when the charge point is not connected to the Internet,

via Wi-Fi.

•        A mobile application (SyncEV), which is available for iOS and Android via the App Store and Google Play respectively. The mobile application can be used by the owner for advanced control, including charging schedule management, charging history, etc.

•        An LED indicator on the charge point that shows the state of the charger.

Electricity supplier interoperability

Charge point is configured such that it will not cease to have smart functionality if the owner changes their electricity supplier| By default, the charge point is connected to the SyncEV CPMS and can be used with any electricity supplier, without losing smart functionality by switching electricity supplier.

Loss of communications network access

Charge point is configured such that, in the event it ceases to be connected to a communications network, it will remain capable of charging an electric vehicle.| The charge point is configured such that, in the event it ceases to be connected to a communications network, it will remain capable of charging an electric vehicle.

There are two main scenarios related to loss of connectivity and the respective behaviour of the charge point:

(1)            Loss of connectivity during a charging session

In the case when an electric vehicle is already connected and charging and the charge point loses connectivity, the charge point continues to charge the vehicle with the same charging schedule that was set at the start of the charging session. This includes the scheduled increase or decrease of

the electricity flow based on the default charging schedule; or a schedule applied by the owner; or a schedule applied by a DSR service;

(2)   Loss of connectivity before the start of a charging session

In this case the charge point would still allow a charging session to be started and depending on the preferences set by the owner, it may require authentication, which is done with one of the physical RFID cards (NFC tags) registered by the owner (or pre-registered when they came with the charge point at sale).

The charge point would schedule the charging according to the last known recurring schedule if any, which is either the default off-peak charging schedule; or a user-defined schedule.

The charge point modes of operation, including the schedule can be configured locally (from the web interface) even when the charge point is offline. This allows the owner to override or change the charging schedule even when the charge point is not connected to the Internet.

Safety

Charge point is configured such that it will not allow a relevant person to carry out a specified operation where to do so would or may result in a risk to the health or safety of persons.

“Relevant persons’ means the owner, or and end-user of the relevant charge point who is not the owner.

“Specified operation” means:

•       Overriding the default mode of charging during the default charging hours

•       Overriding the provision of demand side response services

•       Overriding the random delay

| To carry out any of the following specified operations:

•        Overriding the default mode of charging during the default charging hours

•        Overriding the provision of demand side response services

•        Overriding the random delay

a relevant person would use either the SyncEV mobile application or the charge point’s local web interface.

There is not any physical interaction with the charger needed (like opening the covers, pressing the knobs, handles or jumper installation) or even possible to be used in order to carry out any of the afore-mentioned operations.

The mobile application and the web interface incorporate validation criteria for each input, which would NOT allow the relevant person to enter any values that may result in a risk to the health or safety of persons.

Additionally, the charge point incorporates a validation of any information received either from a cloud CPMS (via OCPP), from the web interface or by any other means of communication.

The validation in place ensures that any command or input received is only executed if it’s within the safe range as defined in the charge point’s firmware.

There are integration tests in place, as part of the continuous development process of the charge point’s firmware, which ensure that the validation checks remain in place with every new software build.

Measuring system

On each occasion it used, the charge point measures or calculates:

•       The electricity it has imported or exported (in watt- hours or killawatt-hours)

•       The amount of time for which it is importing or exporting electricity

| The charge point has a built-in real-time measuring module that measures the imported or exported active energy in kWh and the amount of time for which electricity is being imported or exported.

The accuracy of energy measurement is +/- 2%.

The measurement system conforms to EN 50470-3, class index A.

The charge point is configured such that the owner can view the information in reference to:

•       Any occasion on which it was used to import or export electricity within the past 12 months

•       Any month within the past 12 months

•       The entirety of the last 12 month period

| The owner can view the information in reference to:

•        Any occasion on which it was used to import or export electricity within the past 12 months

•        Any month within the past 12 months

•        The entirety of the last 12 month-period In the SyncEV mobile app

The charge point is configured such that it can:

•       On each occasion it is used, measure or calculate every one second the electrical power it has imported or exported (in watts or kilowatts)

•       Provide this information via a communications network

| On each occasion it is used, the charge point measures the electrical power it has imported or exported in kWh every half second (0.5s).

This information is provided via Internet to the CPMS and is made available in aggregated form, as described in the previous sub-section, to the owner, via the SyncEV

mobile app.

The charge point is configured such that it can:

•       The figures measured or calculated are accurate to within 10% of the actual figure

•       Any inaccuracies are not systematic

| The accuracy of the measurement is +/- 2%.

The measurement system conforms to EN 50470-3, class index A.

Off-peak charging

The charge point:

•       Has pre-set default charging hours which are outside peak hours

•       Offers the owner the opportunity to accept, remove, or change the default charging hours on first use

•       Offers the owner the ability to change, remove, or set default charging hours at any time after

first use

unless the charge point is sold with a DSR agreement, configured to comply with the requirements of this agreement, and details of the agreement are included in the statement of compliance

| The charge point is pre-configured with a default charging schedule outside of peak hours.

This charger is set on the charge point and is applied even when the charger is offline.

The charge point is also configured to connect to the SyncEV CPMS given it is connected to the Internet.

The owner downloads the SyncEV mobile app and after the initial setup of the charger, the app presents the option to the owner to view and accept the default charging schedule (off-peak hours), to set their own schedule or to remove the charging schedule.

Any change of the schedule by the owner in the SyncEV mobile app is communicated to the charge point and stored locally on the charge point, so even if it goes offline, the schedule will still apply.

The way the schedule is communicated to the charger is via the Internet via OCPP. This is how it works:

1. The charging schedule (default or set by the owner) is communicated to the charger (TxDefaultProfile) at first use or at any change made by the owner;

2. When the charger is connected, the charging schedule is applied by the CPMS (TxProfile) at the start of a charging session;

3. When the charger is offline, the charger follows the last known schedule;

4. The charging schedule of the charger can be changed by the owner even when the charge point is offline – via the local web interface of the charger – this is how the owner can edit or over-ride it

when offline

The charge point is configured:

•       To charge a vehicle during the default charging hours (if any), unless the owner overrides the default mode of charging during this time

•       Such that the owner can override the provision of demand side response service

| The charge point charges the vehicle based on the set charging schedule. Unless changed or removed by the owner, the default charging schedule applies.

Using the SyncEV mobile app the owner can override the schedule during a charging session, for the current

charging session – for example if they need the car charged sooner just this time.

The owner can also change the charging schedule by manually selecting the hours during which they want to charge their vehicle.

In the mobile app the owner can use a “boost” option during a running charging session to override the cur-rent schedule or DSR settings for this current charging session. Using the “boost” does not affect the recurring schedule of the charge point but only the current charging session.

Randomised delay

The charge point is configured such that the maximum duration of this delay can be remotely increased to up to 1800 seconds if required| The charger can be reconfigured remotely to increase the max randomised delay to up to 1800 seconds. This is done via OCPP by changing the value of a specific configuration key.

The default maximum duration of the delay can be adjusted in the SyncEV CPMS backend, and the change is communicated to the charger with an OCPP command to change the specific configuration key that controls the random delay duration.

---|---
The charge point is configured such that the random delay will not operate where:

•       The owner or another relevant end-user has manually overridden it

•       An equivalent random delay has already been applied to the operation of the relevant charge point

•       The charge point is responding to a response DSR service

| A randomised delay is not applied in the following cases:

•        The owner uses the Boost function in the app

•        The owner edits the charging schedule during a charging session

•        A flexible electricity tariff is used to determine the charging schedule (such as Agile Octopus)

•        Power is increased/decreased by Dynamic Load Management (local, or cloud)
