EV Home Charging
EV home charging is cheap and convenient. With a smart charger and an EV tariff, you can access rates as low as 5p per kWh.
Charger Installation Process
The first step in the process is home charger design, where we consider your property’s electrical installation (e.g. RCD location), how you will use your EV charger, your budget and your lifestyle.
Installation begins with drilling for the cabling. We will then run the cabling, hook it to the RCD unit, take care of the connection, and move on to the next step (installing the charge point).
The next step is fixing the EV charge point to the wall and connecting it up with the cabling we installed earlier. Your EV charger may need an earth rod, or not, it depends on the type of charger and your electrical installation.
Once the EV charge point is wired up, we label the RCD switch for EV and take care of finishing, like plugging drilled holes and installing new silicone.
The last step is testing the unit and checking the RCD. The process takes 3-4 hours per charger on average. Job done!
EV Charging Speeds
The slowest home charge points charge at only 3.6kW, which is less than twice as fast as a 3-pin plug. You should choose a 7kW charge point instead, which is more than twice as fast as a 3-pin plug, adding around 30 miles of range per hour.
7.2kW, 7.3kW and 7.4kW chargers also exist, giving you marginally faster charge speeds. If you want even faster charging, the fastest charge speed for properties with a single-phase power supply (99% of domestic properties) is 11kW.
11kW home chargers are increasingly supported by modern EVs, although the difference in range added per hour compared with 7kW is only around 5-8 miles.
EV Charging Brands
Some car brands like Tesla have brought out their own home chargers (Tesla Wall Connector), while some fuel companies like BP have too (BP Chargemaster).
Between these are a wide range of high-quality chargers from ABB, INDRA, Schneider, Ohme, Project EV, Podpoint, Pulsar, Andersen, EO, Rolec, Hypervolt, Zappi and EVBox.
Of all these brands, we have most experience with Andersen, Podpoint, Project EV and Zappi. All four of these brands have high-quality home chargers, with exemplary circuitry, build quality and connectivity features for the future.
Charger Installation Costs
Installation costs with ecoEV start from £899, getting you a 7kW charge point with around one metre of cabling. If you want a fully connected charge point with solar integration and smart grid support, you will pay around £1,299.
Brands also have different prices. For example, Andersen is more expensive than Project EV, but that doesn’t mean it is a better brand. You will always pay more for fancier features like 4G SIM connectivity, smart grid-enabled, and solar integration.
EV Home Charging Costs
Charging an electric vehicle at home during peak times will cost around £6 for a 5-100% charge with a 60kWh battery, or £3.40 off-peak. However, you might need to change to an Economy 7 electricity tariff to benefit from off-peak electricity rates.
The average peak electricity rate in the UK is 17p per kWh while the average off-peak electricity rate is 7p per kWh, so scheduled charging is essential to save money. The bigger your vehicle’s battery, the more you will pay to charge it at home.
