Confused about the difference in home EV chargers and what each feature means?
What’s RFID? What’s Load Balancing? What’s an Earth Rod? It sometimes feels like another language…
But don’t fret! You have come to the right place. In this blog, we will be explaining what is meant by the term smart EV charger and going over some of the key smart charger features out there.
According to the government, a smart EV charger is categorized as an electric vehicle charger that has “connectivity”. The EV charger must be able to send and receive messages and be able to manually adjust the rate of charging to fit the electricity flow.
If you are wanting to claim the £350 discount from the OZEV grant, the EV charger you choose must be classed as “Smart”. This is because, with the increase in electric vehicles and their charge points, the government are wanting to protect the grid from draining too much power. By encouraging smart EV car chargers, users will also benefit from the variety of special features. When you use a home smart EV charger, you have the ability to schedule charging, which allows the user to schedule exactly when their EV will charge, for example, overnight when the grid is not in demand. Charge scheduling, therefore, benefits the grid and the home user.
A dumb electric vehicle charger is a basic EV charger that simply charges. When you plug the charger into the EV socket, it will start to charge. Once you have finished, you just unplug it. Simple. However, dumb EV chargers do not qualify for the OZEV grant, as the government are encouraging the use of smart chargers to support the grid. A dumb charger cannot be managed manually and does not have any features, therefore, charge scheduling is not possible.
All smart EV chargers should come with their own branded App, available on the Apple App Store and on the Google Store. This is where you will be able to manage the majority of your smart charging point’s features. Different manufacturers have different apps, and usually they are named after their brand name i.e., Hypervolt has their own app, under “Hypervolt”. Most Apps will show real-time energy cost information and extensive charging analytics (such as how much it costs you to charge your EV and what charge percentage the EV is on).
On the App, you will be able to control a number of the chargers’ smart features with just the touch of a button. Let us talk you through a few common features of smart EV charger Apps:
Most smart EV chargers allow you to schedule your charging, and you use your specific manufacturer App to manage the feature. By scheduling exactly when your EV charges, you can charge cheaper. For example, you can take advantage of your off-peak electricity rates by scheduling your EV charging between these hours. You can also set up multiple schedules at your convenience, such as creating a schedule to fit your commute.
Either way, you can decide exactly how and when you charge without much faff. A lot easier than going to the petrol station – right?
If your charger has the Cable Lock feature, you will be able to lock and unlock your cable through the manufacturer app (if applicable). An example of a smart EV charger that currently offers this feature is the Easee One. This feature ensures your charger is secure and safe from theft. However, this feature will only be on available for socketed or sometimes called “untethered” units. With a tethered electric vehicle charger, the cable is already attached to the unit and, therefore, cannot be removed, so the cable lock feature is not needed.
RFID means Radio-Frequency Identification and simply put, smart EV chargers with this feature come with a special RFID card that you can use to start and stop your charging sessions. The charger will have a built-in card reader, so you scan your RFID card over the identification area on your charger to start charging. You can then end the charging session by scanning the RFID over the identification area again. However, some chargers will just automatically stop charging once it is fully charged. No internet connection is normally required for this feature. Having a RFID card means that you don’t have to fiddle around with an App, but you are still protected from others using your charger without permission as they will need either the RFID card or the App to start the charging.
If your charger has smart home integration, you will most likely be able to sync your charger with your Amazon Alexa and easily control a variety of features with Alexa voice control. One of the most popular electric vehicle chargers with this feature is the Hypervolt EV charger, where you can control your charging and the brightness of the light indicator with your voice. How fancy is that?
If your smart charger comes with a status light indicator, a light will be positioned typically on the front of the charging box (usually LED), allowing you to get a clearer picture of what is going on with your charging point. For example, if a clear green light is displayed, everything is well with your charger, but if it is red, something is definitely wrong.
If your home smart EV charger has the option of pin security, this feature will provide you with another way to lock your EV charger from any unauthorised use. The charger will require a PIN number to be entered before the unit can be operated and/or a charge is allowed, typically through the App.
If your electric vehicle charger has the free wireless over-the-air software updates feature, it means your charger automatically updates to the latest firmware without having to update the charger yourself or having to call an installer out, benefiting you with new features from the get-go.
Plug and Play or sometimes called “Plug & Charge”, is where you simply plug the charging gun into your EV and it automatically starts charging; no app, card or code needed.
No Earth Rod is not exactly a feature, but it is a benefit. An Earthing Rod is a vertical copper rod inserted into the ground with a black connection box and conduit at the top, which then connects to your home charger. If your chosen EV charger has built-in earthing arrangement, it just means there is no costly groundwork, holes in driveways or additional mess from having to insert a rod/rods. An Earth Rod is not required when the charger has built-in PEN protection (detection + isolation). Having no earth rod is just more aesthetically pleasing to the eye; a number of our chargers including the Hypervolt and the Easee One, do not require earth rods.
An important safety feature as it prevents overload of your electrical supply. The charger is set to a limit that matches the size of the main incoming supply fuse, it then constantly monitors electricity usage in the home and alters the charge rate to the EV to suit. For instance, if the limit is set to 60A and 40A is used in the home elsewhere then charging to the EV will drop to 20A. This keeps the maximum demand to 60A and prevents the main fuse from blowing and limits the chance of a total loss of power.
If the electric vehicle charger has the feature of being solar-ready, it means that the unit is compatible with all installations and has built-in solar-compatible software already. No additional add-on purchases are therefore needed! So, as long as you have solar panels on your roof, you can use solar power to charge your EV as soon as the solar EV charger is installed. Using solar energy is also a great way to help support the grid whilst keeping costs down, as solar charging is completely FREE!
Solar compatible means that whilst your EV charger can use solar to charge, it doesn’t come as standard, unlike if the unit is Solar Ready. Typically, an add-on purchase is needed for the unit for it to be able to charge. An example of a smart EV charger with an add-on needed for solar is the Zappi EV charger. You will need to purchase either a singular CT clamp to monitor and direct your surplus solar/wind energy into your car, or purchase two CT clamps in order to get full visualisation of how much energy is being produced and where it is going.
