myenergi ZAPPI-2H07UW Zappi Eco-Smart EV Charge Point

introduction

Electric Vehicles (Smart Charge Points) Regulations 2021
From 30th June 2022, any EV charger installed in a private setting i.e. home or workplace NOT public, in England, Scotland and Wales has to meet the Electric Vehicles (Smart Charge
Points) Regulations 2021.

Purpose of the Regulations
The new smart charging regulations are a huge, positive forward-step by the UK Government in preparing our homes and businesses for a smart, connected and democratized energy system. Essential tools in driving down emissions and a core reason why myenergi exists.
The regulations are focused around when you are charging an EV. The aim of the regulations is to prevent everyone charging at the same time and putting too much demand on the grid.

What’s changed with zappi
New features have been added to zappi to ensure our products remain compliant with UK Regulations.

Date & Time – Allows the zappi to know if it is being installed on or after 30th June 2022. If it is then smart regulations must apply.
First Device – If this is your first myenergi device the zappi will opt to set the device as Master and turn the in-built vHub on. If you are adding to an existing myenergi eco-system, the device will opt to set as slave and turn the in-built vHub off.
Geographic location of installation – If the device is being installed outside of England, Scotland and Wales the Smart Regulations don’t apply.

• Randomised Delay – At the start of a charge and end of a scheduled, Timed Boost there will be a delay of up to 10 minutes before your vehicle starts and stops charging. This could be a few seconds or it could be up to the full 10 minutes. This is necessary to ensure everyone does not overload the grid by starting to charge or ending a charge at the same time. The Randomised Delay can be overridden, if necessary (See 1.3.2 for further details).
• Smart Scheduling – To comply with the smart charging regulations your zappi will be set to charge in off-peak hours by default. This is between 00:00 – 08:00. You may change this schedule at any time if you would prefer to charge in peak hours or your electricity tariff off-peak hours differ from those set.
• Default to ECO+ mode – If Smart Regulations apply, zappi will default to ECO+ mode on first boot up.
• Charging logs – You will now be able to view a record of charging logs from the past 13 months. See Charge Logs section below for further information

Randomised Delay: How it works

As mentioned above, Randomised Delay will put a completely random delay at the start of a charge and end of a scheduled, Timed Boost, for up to 10 minutes. This can be overridden by the customer in situations where they are in a hurry.

Delay Status

You will be able to see if your charger is in a state of delay at any time as it will be displayed on both the zappi screen and in the myenergi app.

Overriding the delay
To override the delay simply press the ‘+’ button on the zappi or press the ‘charge now’ button displayed in the pop-up message within the myenergi app. If the delay is overridden your charge will start/stop immediately.

You cannot permanently override the delay function. If you wish to override the delay each time you charge, you will need to follow the above instruction to override on every applicable charging session.

Smart Scheduling: How it works

As summarised under section 1.2 your zappi will be set to charge in off-peak hours by default from initial start-up.

Off-peak hours
Off-peak hours are usually between 00:00 – 08:00, depending on your specific tariff, this is when your electricity will be at it’s cheapest.

Reason for Smart Scheduling
Encouraging you to charge in off-peak hours prevents overloading the grid in peak times.

Benefits of Smart Scheduling
Smart Scheduling will can help you spend less on your electricity. By charging in off-peak hours your electricity tariff may be cheaper.

Changing the set schedule
If the default schedule does not suit your requirements, or your electricity tariff’s off-peak hours differ from the schedule set, you can amend your schedule at any time from the zappi menu or within the myenergi app.
To adjust your schedule in the app navigate to the ‘Set Boost Parameters’ option, select start time and set the number of hours you want your charger to boost for.
To change the schedule on your zappi device navigate to ‘Charge Settings > Boost Timer’ and amend the schedule as desired. For further information see the Timed Boost section of the User Manual.
Alternatively, the schedule may be deleted altogether, if required. To do this ensure all inputs are set to 00:00 for each day of the week.

Defaulting to ‘ECO+’ Mode

As mentioned in section 1.2 if your zappi meets the Smart Regulation parameters it will default to ECO+ mode upon first start-up. This can be changed to ECO+ or FAST mode at any time by the customer. See Charging Modes section of the User Manual for further information on modes.

Manual Boost

If you choose to remain in ECO+ mode you can still charge from the grid at any time by doing a Manual Boost. Refer to Manual Boost section of the User Manual for further information on this existing feature.

Charging Logs

Providing your zappi is internet connected and you have registered your device in myaccount you will be able to view a record of charge logs for the last 13 month period. This function will begin from 30th June 2022 so the earliest time you will see the whole 13 months will be from July 2023 or 13 months from when your device was connected to the internet. The charge logs will tell you when the charge started, when the session ended and the duration of each session.

To view your logs log into your account at https://myaccount.myenergi.com/login 

Navigate to “My Energi Usage” in the left hand menu. The charge logs will be displayed like to example below.

Installer Requirements

It is the responsibility of the installer to ensure they are compliant with Electric Vehicles (Smart Charge Points)
Regulations 2021. This includes, but is not limited to:

• Installing only compliant charge points in private installs from and including 30th June 2022.
• Answering the start-up wizard questions accurately to reflect actual install parameters.
• Keeping a register of sales from and including 30th June 2022, for a minimum period of 10 years.
• Having a Technical File and/or Declaration of Compliance available if requested by the customer (myenergi’s Technical File and Declaration of Compliance is available at:
  https://myenergi.com/guides/smart-charge-point-regulations-explained/

Overview

Microgeneration systems such as Solar PV and small wind turbines are at their most efficient when the generated energy is consumed on-site rather than exporting it to the grid. This is what we call ‘self-consumption’.
zappi is a Mode 3 charging station, compatible with all electric vehicles that comply with EN 62196 and EN 61851-1 plug-in electric vehicle standards.
zappi works like any regular charging point but has special ECO charging modes that will benefit homeowners with grid-tied microgeneration systems e.g. wind or solar generation. Two special ECO charging modes automatically adjust charging current in response to on-site generation and household power consumption. In FAST charge mode, zappi operates like an ordinary EV charger.
A grid current sensor (supplied) simply clips around the incoming supply cable and is used to monitor excess power. When using the special ECO charge modes, zappi will automatically adjust the charge rate in response to available surplus.

Charging Modes

zappi has three different charging modes and a “STOP” mode which can be selected simply by pressing the
and buttons when the main screen is showing. The charge mode can be changed before or during a charge. Regardless of the charge mode, all the surplus electricity is used zappi’s special eco charge modes limit the amount of grid electric used. Below is the explanation of each charging mode.

Charges at the fastest rate

Fast Mode will charge the EV at the fastest rate and will import grid electricity if there is insufficient surplus generated power. The actual charge rate is dependent on the EV’s onboard charger and the grid supply voltage. Some vehicles can charge at 11kW or 22kW on a 3-Phase zappi, but many EV’s have lower charge rates. The maximum charge rate for the single phase zappi is 7kW.

Adjusts the charge rate to limit the use of grid electricity

The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power.  Charging will continue until the vehicle is fully charged, using available surplus power.  If at any time, the available surplus power falls below 1.4kW, the shortfall will be drawn from the grid.

Note: The EV charging standard does not support below 1.4kW.

Adjusts the charge rate to limit the use of grid electricity and will pause the charge if there is too much or any grid electricity being used (Set-up Dependant)
The charge rate is continuously adjusted, in response to changes in generation or power consumption elsewhere in the home, thereby minimising the use of grid power. Charging will pause if there is too much imported power, continuing only when there is enough surplus power available. The surplus power threshold at which the charge will start or stop can be set using Min Green Level in the ECO+ Settings of the Charge Settings menu. The actual green contribution percentage is shown when the charge is complete or when the zappi has been disconnected from the EV. It is possible to charge the EV using only surplus renewable power, if there is sufficient surplus power available and a boost option has not been set. (Please note: The EV charging standard does not support charging below 1.4kW) Example: when zappi is set to a Min Green Level of 100% you will need in excess of around 1.4kW of surplus energy available to start the charge. If the surplus falls below the 1.4kW threshold the charge will pause until the threshold is once again met. After a short delay zappi will resume charge. If preferable, you can set the zappi to share power from the grid and a generation source to ensure a charge is always maintained. For example, the Min Green Level could be set to 75%. A charge will then start when there is a surplus of 1.05kW, taking a further 0.35kW from the grid. It is worth noting that this is only required to start a charge. If a higher amount of surplus becomes available it will be consumed, resulting in less being drawn from the grid.

The output from zappi is turned off
In STOP mode zappi will not charge your EV. This includes the boost modes and timed boost. zappi will continue to measure power and communicate with the other myenergi devices.

Manual Boost

The Manual Boost function can only be used when charging in ECO or ECO+ mode. When boosting, the charge rate is set to maximum (just like FAST mode), until a set amount of energy has been stored in the EV’s battery. After which, zappi will revert to ECO or ECO+ mode.
This function is useful if you arrive home with an almost flat battery and would like to charge the vehicle immediately to ensure there is enough charge for a short trip if needed.
The amount of energy delivered to the EV during the boost charge can be changed in the Charge Settings/Boost menu.
When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below:
