Easy, intelligent, and insightful. EVBox Everon lets you track, manage, and optimize electric vehicle charging from the palm of your hand.
Compared to buying your electricity via a third party, you can take advantage of the relatively cheap electricity from your residential grid.
With smart charging features like remote control, you can stop and start charging your vehicle with the click of a button.
Connect your residential charging station to a solar panel or 100 percent renewable energy for emission-free driving.
Residential charging stations come in a range of shapes and sizes and are designed to withstand all weather conditions.
Because you can charge at home, you don’t have to go out of your way to charge up on the way home.
With power outputs between 3.7 kW and 22 kW, home charging stations are made to suit any passenger EV.
By installing a residential charging station at your home or apartment, you can charge as you eat, sleep, and play, all while making sure your vehicle is ready-to-go the next morning.
Generally speaking, there are three different types of EV charging: Level 1, Level 2, and Level 3. Level 2 charging stations are by far the most convenient charging stations for homes and apartments due to the fact that they’re significantly faster than Level 1 stations, and don’t usually require costly upgrades to power supply like their Level 3 (DC fast charging) counterparts.
Residential charging stations are usually Level 2 charging stations and can deliver somewhere between 3.7 - 22 kW of power output. These electric car charging ports work by connecting to your home's electricity supply via either 1-phase or 3-phase connectors. With a Level 2 charging station at maximum power output, one hour of charging will provide approximately 120 kms of range.*
To compare, Level 1 charging stations—which plug directly into the wall socket—have a maximum output of 2.3 kW. With a Level 1 charging station at maximum power output, one hour of charging will provide approximately 20 kms range.*
Home chargers are also more cost effective than public charging stations as they make use of cheaper electricity from the residential energy grid during off-peak hours or with electricity generated by sustainable energy supplies (e.g. solar panels).

*Calculations are approximations based on the average consumption of 18 kWh per 100 km. Actual consumption depends on the vehicle, battery size, and driving conditions.
With a Level 2 residential charging station, most electric drivers will be able to charge their electric vehicle overnight and be ready to hit the road the next day.
Level 2 charging stations have a maximum power output of 22 kW. At 22 kW, a charging station can fully charge a Tesla Model 3 in approximately three hours and 45 minutes. Level 2 charging stations are ideal for home scenarios because they deliver maximum power to an EV without requiring costly grid upgrades, depending on your location of course.
However, as with all hardware, there are variables. The speed of residential charging stations varies depending on the type of charging point 1-phase, 3-phase, and whether they deliver 16 A or 32 A, the residential location’s power output, and the type of EV. To get a better understanding of the different charging speeds for a Level 2 charging station, here's an overview of how long it will take to charge a Tesla Model 3.
|Level 2: 1-Phase, 16A||3.7 kW||14h45m|
|Level 2: 1-Phase, 32A||7.4 kW||7h20m|
|Level 2: 3-Phase, 16A||11 kW||5h00m|
|Level 2: 3-Phase, 32A||22 kW||3h45m|
Beyond the type of charging station you choose, how fast your home charging station will charge your EV comes down to the amount of power you can take from the grid. Some residential homes may not be wired to deliver 22 kWs of AC, affecting charging speeds.
To attain your desired charging speed, it may be necessary to upgrade your electrical supply. But before you do, it's important to understand what your vehicle is capable of.
We always say that the EV is the ultimate deciding factor in charging speeds due to the vehicle's conversion capacity. As the power from the grid is AC and an EV’s battery charges with DC, the current must be converted. If an EV’s AC/DC converter only allows for conversion at 11 kW an hour, then even with 22 kW output, the EV will take twice as long to charge.
For a Tesla Model 3, a 3-Phase, an 11 kW charging station is best suited due converter's capacity (11 kW) and the size of the vehicle's battery. With it's 6.6 kW on-board charger and comparatively smaller battery, a Nissan Leaf driver would be better off choosing for a 1-Phase, 32A charging station. It's important to have an overview of these details—both for your home and your EV—if you're considering investing in EV charging for your residence.
The short answer is yes: residential charging stations should work with all types of electric passenger vehicles.
However, there are a few variables. Whether a particular EV is compatible with a specific home charging station depends on the vehicle’s socket, the type of connector of the charging cable (CHAdeMO or CCS2), and whether the charging station’s cable is fixed or not.
When looking to invest in a charging station for your home or apartment, these details will be specific to the vehicle you drive and thus, may limit the capacity for other vehicles to charge using the same charging port.
What about charging Tesla with home charging stations?
Again, the short answer is yes. With any Level 2 charging port, you will be able to charge your Tesla, providing you have the right connection for the charging station. Although Tesla has their own home charging installation setup including the Tesla Wall Connector, Tesla vehicles are compatible with many other brands on the market via a CC2 or CHAdeMO adapter.
The price for charging your vehicle at home depends entirely on how much you pay for each kilowatt-hour (kWh) of electricity used.
In the US, the average price per kWh is around $0.13 while in the EU, that number is comparatively higher at an average domestic price of €0.21. And across the EU electricity costs vary greatly. For instance, in Germany the price per kWh climbs to around €0.30 on average. Furthermore, these prices will change at certain times of the day; you'll likely pay more for charging during the day than in the middle of the night.
But what does this mean? If you're looking to fully charge a Nissan Leaf with a 62 kWh battery in the EU, you’re pay around €13 with a maximum range of 364 km. However, if you’re looking to charge a Tesla Model X with its larger, 95 kWh battery, it will cost closer to €20 with a range of up to 625 km.
To keep the price of charging down, you can connect your residential EV charging station to a charging management platform. Charging management platforms have intelligent features including autostart — starting charging during low-cost periods — and dynamic load balancing — which safely balances the energy usage between a charging station and other high-power usage appliances.
In the long run, how much it costs to fully charge your EV at home will depend on a number of factors. However, the ultimate cost is still comparatively lower than for vehicles with internal combustion engines, not to mention the reduced cost to the environment due to CO2 emissions, and to our health care system due to air pollutants.
Just like the cost of any hardware appliances, the installation cost of a residential charging station for electric vehicles varies greatly, depending on your location, your requirements, and whether you require assistance to install the charging station.
The general rule of thumb is that the more power output a charging station is capable of, the more expensive it will become. Level 2 charging stations can cost between €600 and €1,500 (on both sides of the Atlantic), providing that you don't have to upgrade your electrical supply.
Before investing, it’s important to make sure that you ask yourself:
The answers to these two questions will directly affect which residential charging station will suit your needs. To install an EV charging station at your home, you can use either 1-phase and 3-phase power. The difference between the two is the amount of conductors which the power flows through (one or three respectively). 3-phase charging can transfer more power than the 1-phase (22 kW versus 7.4 kW max power output) but may be more difficult and costly to install.
Whichever charging station you choose, installation must be performed by a certified electrician.
When calculating the price of a residential EV charging station, keep in mind that governments and energy companies across Europe and North America have incentives which promote electric vehicles and in certain places, subsidise the cost of charging ports. Learn more about European incentives here.
The difference between economical home charging and home charging that leaves you out-of-pocket comes down to the features which the charging station provides. Features including whether you use scheduled charging, draw energy from the grid or use solar panels, and optimize your charging experience all contribute to cost-effective charging. Here are five features to consider:
Before investing in a charging station, it's important to look into which of these features suits your needs and whether the charging station you choose provides them.
