When thinking about charging your electric vehicle at home, it is important to find out about all aspects of this operation, from charging devices and wallbox features to the possible costs of increasing the power of the meter.
In general, there are three ‘problems’ to be addressed with a classical 3 kW meter:
1. if you only have a power of 3kW, all you have to do is attach a hairdryer or an oven combined with car charging to blow the power;
2. with a 3kW meter it takes days to fully charge the car battery;
3. sockets and cables in the wall may not be able to withstand the kW absorbed by the charging process, resulting in melting and catching fire. There is no shortage of cases of fires caused precisely by the home charging of electric cars, although the more expensive models have sensors that detect the temperature at the plug and stop the power supply if it overheats.
These are variable power devices that reach up to 7 kW using normal single-phase current and up to 22 kW with two-phase current. In particular, they are devices that are able to self-regulate their power so as not to exceed the power still available, i.e. the maximum power at the meter, minus all other domestic consumption, thus preventing the user from being left in the dark.
How a domestic wallbox works
The home wallbox is at the heart of the electric mobility revolution, and these home battery charging devices resemble public charging stations in every way, although they are smaller and wall-mounted.
It is a solution to optimise the available space and reduce the footprint, turning the simple socket into an advanced charging point. Just follow some regulations, such as CEI EN 61851-1 and the safety parameters to start charging your electric car at home. In any case, the wall box should be placed in garages, car boxes and other rooms outside the home, while in apartment buildings direct connections of the EV to the charging stations will be preferable.
The advantages of this system are safe recharging with homogeneous energy exchange that preserves the battery. Compared to conventional sockets, the service can be upgraded, with faster charging and higher performance, taking into account that a conventional single-phase cable supports just 2 kW, while the Wall Box can reach up to 7.4 kW.
How much does it cost to increase meter power
Many citizens and companies find themselves in the position of having to increase their meter and the power they supply, particularly when the power goes out if they use many devices at the same time or operate machinery that requires more meter power.
In any case, for those upgrading from 3kW to 6kW, the initial expenditure for power increase rises to around € 225.00, then the annual impact on the bill is around € 71. Again, I will always pay the kWh at the same price.
In the free market, the cost of increasing meter power depends on the contract and the costs are the same as in the protected market. What changes is the fixed administrative fee, i.e. the charge due to the supplier for passing on the power increase order to the network operator.
Charging your electric car at home pays off
DazeTechnology‘s advice to electric car owners is to recharge at home, especially if you have a garage or garage where you can park your car for the time it takes to fill up with energy. The costs of a 40 kWh battery recharge are affordable for everyone and you can contact our technicians to purchase a smart wall box such as DazeBox C, which allows you to manage the energy of the recharge without the need for an increase in meter power. An advantageous option if we consider that, to recharge the electric car at home with a normal 3 kW power meter and a fully discharged 40 kW medium-sized battery, it will take about 12 hours for the charge to be 100% complete.
