Electric vehicle home charging: Everything you need to know

If you’ve got an Electric Vehicle, an electric car charger is an excellent addition to your property! Especially if you have or are thinking about getting solar panels. This article aims to answer some of the questions you might have about getting an EV charger and how to use it works to charge your Electric Vehicle with solar power.

Are all EV chargers compatible with all EVs?

Yes and no. Electric vehicles do come with different connectors. Type 1 and Type 2 are standard for now, but Type 2 is expected to become standard in the future. However, there are Type 1 to Type 2 adaptors, so although it makes sense to choose a home car charger point that is compatible with your EV, this doesn’t lock you into a specific type of EV in the future. If you’ve got an untethered charger this is even less of a problem as the cable between the charger and your EV is fully detachable. You can read more about the pros and cons of tethered versus untethered chargers in another one of our Green Guides.

Can I charge my EV with solar power?

Yes! Charging your electric vehicle with solar power is a great way to make your EV even more environmentally friendly! You can read more about charging your EV with solar power here. Note that you don’t need to install your EV charger at the same time as your solar panel system in order to charge your car with solar. You will need an EV charger which is able to pull electricity from your panels, though.

Do I need a full solar panel system with an inverter to charge my EV with solar power?

Yes, if you want an electric car charger for home that is powered by solar power you need to set up a whole solar panel system to do so. You will also need to have a car charger installation in case you don’t already have one installed. We’re happy to help you with both!

Where can I install an EV home charger?

In addition to taking into consideration where you’d like to charge your car, you need to ask yourself two questions. The first one is whether wiring pathways can be run between the location you have in mind for the charger and your fuse board, as these need to be connected. The second question is whether the fuse board that you’re hoping to plug the EV charger into can support a car charger fuse.

What is a smart EV charger?

Simply put, a smart EV charger is an EV charger which one is able to access remotely and which is capable of receiving a signal, interpreting it and reacting to it.

Do I need permission for an electric car home charging station?

Most network operators require notification whenever an EV charger is installed. If we can install the car charger on at least a 60 amp circuit then we need to notify the DNO post installation only. If you don’t have one we can install a 60 amp fuse saver as part of our installation. If this isn’t possible, then you might need to notify the DNO prior to installation. In either case, if you have your installation through our platform we’ll do this for you!

How long will it take to charge my car at a home EV charging station?

It depends on the size of your car battery and the rate at which it’s charging at. If you have a 7kW EV charger and you have a 40kWh car battery, it would take about five and a half hours to charge up to 40kWh.

How much does it cost to charge an EV at home?

How much money it’ll cost you to use a home car charging station depends on what source of electricity your EV charger pulls from. If you’ve got solar panels installed and your EV charger is solely feeding solar generated electricity into your car, charging your EV is essentially free. If you haven’t yet seen return of investment on your solar panel system, you might not see it that way. But in itself, the act of turning the electricity generated by your panels into juice for your car is free of charge.

If you charge your car with electricity from the grid, how much it’s going to cost you depends on your tariff. According to OFGEM, the typical customer paying by direct debit is paying 28p per kWh for electricity under the price cap that took effect on 1 April 2022. If you're paying 28p per kWh of electricity and have an averaged sized car battery of 40kWh, it would cost you £11.20 to charge up your car battery.

With the myenergi zappi, you’re able to choose which source of energy you want the charger to use to charge your electric vehicle. This could be exclusively solar, exclusively the grid or exclusively any excess produced by your solar panel system. Or a combination of all of the above!

What’s the best home EV charger?

We find that for properties with solar installations, myenergi’s zappi charger pairs best with your solar system. This is because unlike other car EV chargers it is able to charge up your car exclusively on solar, exclusively on the grid, or exclusively on excess solar energy produced by your solar system, or a combination of all of the above. Does this make it the best home EV charger in the UK? Certainly if you ask us!
