Supported content – In terms of household, the electric car is a big consumer, so it is worth checking the electrical network before setting up a charging station.
There are a large number of properties in the Hungarian housing stock where the electricity network was built even in the last century, you can even find aluminum wires and fuses – see cube houses. By charging the electric car, we introduce a large consumer into the household, which means an increased load, it is worth reviewing the electrical network and its performance with a specialist before introducing a new consumer, and the connections should be faultless. It is important that the load on the consumers on the given circuit – used for electric car charging – is properly dimensioned, it may be expedient to build a separate circuit for this purpose, with its own circuit breaker.
Charging a battery-electric car from a simple outlet is a lengthy, inconvenient solution, so it’s worth investing in a wall charger. Many car manufacturers even offer this as part of a promotion and also provide assistance with installation / commissioning with the help of local electricians. If the performance and construction of the electrical network is adequate, it is not justified to involve an electrician registered with the electricity supplier in the process, it is more important that the work is carried out by a specialist who is familiar with the charging equipment. A registered installer is required in the event that the electrical network needs to be upgraded or its capacity needs to be expanded, the cost of which is regulated by law, and the cost of any larger diameter cable must be borne by the user requesting the upgrade. Incidentally, grid expansion may be important not only because of electric car charging, but also as a general trend that more and more consumers are consuming electricity.
There is no special legislation for this, but it is not recommended to install an electrical charging point in a place where there is a risk of fire or explosion. The service providers recommend the installation of a current protection switch, a fire isolating switch and a surge protection, the cost of which is a fraction of the total investment cost.
