When one buys an electric car, one wonders how it will be recharged at home and how much it will cost to consume electricity at home. This is why DazeTechnology wants to answer the main questions of those who have been fascinated by the advantages of electric models and have decided to rely on home charging.
How to recharge your electric car at home
To charge your electric car at home, you need a wallbox or socket that can withstand high loads for several hours, based on the characteristics of your meter. In this case DazeTechnology recommends the latest generation wallboxes, but those who only travel a few kilometres can also use a portable charger combined with a 3kW generator. This is only suitable for those who do not exceed 80/90 km per day and requires a total of 15 kWh, to be recovered in 8/10 hours. Those travelling 150/180 m need up to 25/30 kWh and 10 hours with a single-phase 13A (3.6 kW) charger will suffice. In this case, a meter power of at least 4.5 kW is recommended, or better 6 kW if you want to be on the safe side, with the possibility of charging even during the day while some domestic appliance (hairdryer or microwave oven) is in use at the same time.
The duration and number of hours required for electric car charging depends on many factors:
- Charging power in kW from the mains socket;
- Maximum power accepted by the vehicle’s internal charger;
- Type of cable used;
- Capacity of on-board storage system and state of charge.
Below is a rough indication of charging times based on the technology available on the market:
- Charging stations for the residential market (typically 3.7kW to 7.4kW): charging from 5 to 12 hours;
- Charging stations by business segment (typically with power greater than 7.4 kW, typically 22kW;
- Charging stations for public use with power ratings from 22kW;
- Quick stations with power up to 22kW: charging in 2 hours;
- SFast stations (installed on state roads and motorways) with power up to 50kW: recharging in less than an hour;
- Ultra Fast stations with power up to 350kW: charging in less than 25 minutes
The calculation is made considering a car with a 40kWh battery, from 0% to 100%, and as can be seen, the time for home charging is significantly longer than for charging from a public charging station.
Electric cars will reach 125 million units in 2030 and will bring benefits to the environment by cutting polluting emissions as well as saving money for users as it is always cheaper to fill up an electric car than a conventional engine.
Fully recharging lithium-ion batteries depends on the cost of electricity, location and tariffs, but the type of recharging, the capacity of the car battery and the level of recharging you want to achieve all contribute to the final price. If you have a 45 kWh battery now and an electricity cost of 0.20 euro/kWh, you will pay 9/10 € to fill up your electric car for a yield of 1200 kilometres.
How much energy is consumed by charging
As is well known, the consumption of an electric car is expressed in kWh, and it is the vehicle model and the size of the battery that affect the bill. One reasons in this case in km per kWh and the electric cars on the market today do 200-400 kilometres on maximum charge and have a consumption of between 6 and 8 km/kwH. Considering that for a power output of 3kW, the cost of a kWh is around €0.20, this means that with one euro you cover almost 40 kilometres.
To consume less and save on bills, one can set up a photovoltaic system and choose a home wallbox for charging electric cars at home like the one proposed by DazeTechnology. Combined with a cost-effective energy plan, it maximises economic and other benefits and meets the needs of every customer.
