The development of electromobility in Poland is gaining momentum, which on the one hand brings benefits - ecological, but on the other hand creates challenges related especially to energy infrastructure. This is because charging electric cars is becoming more frequent, which is not without impact on the durability of electrical installations. If such cars increase and are charged simultaneously, overloads may occur. There is such a risk, especially if the systems are not properly adapted. This clearly shows that the selection of appropriate technical solutions, such as modernization of installations, the use of intelligent chargers, as well as power planning, is becoming necessary both for the stability of the network and the safe use of electric vehicles.

Will every electrical installation be able to handle charging an electric car?
Electric cars are the future that is happening before our eyes. They may not yet be as common as cars powered by a combustion engine, but electric cars are gaining an increasingly strong position. Along with their slow but systematic expansion, questions related to energy availability arise, including whether every electrical installation can handle charging an electric car?
This is unfortunately impossible, because not every such installation in houses or apartments can handle the loads generated by the charging process. The charging time of an electric car is particularly important here, which can be so long that the installation cannot handle it. What is more, standard installations in older buildings are not able to handle the charging current. It can range from 7 to even 22 kW, depending on the charger power. Overloading the installation can lead to dangerous overheating of the wires or tripping of the safety devices. Worse still, it can even lead to a fire.
To avoid this threat, it may be necessary to modernize the installation, during which it is necessary to increase the cross-sections of the cables, install appropriate protections and a dedicated circuit for the charger. Another extremely important step here is to select a charger with the right power, tailored to the installation in a given building. It is best to choose a proven manufacturer, which is why we can recommend Wallbox wall chargers . If we are planning a new installation and also want to buy an electric car, let's plan its charging right away, taking into account the future energy needs of the network so that it can withstand the load.
Will the networks cope with the load of charging electric cars?
We already know that not every electrical installation can handle charging electric cars, so let's check how it looks in the case of the network. If this happens on a mass scale, it can undoubtedly be a big challenge for industrial networks. And this is despite the fact that they are designed with a certain power reserve. Nevertheless, a sudden increase in energy demand can lead to overloads. This can happen especially during peak hours, when many electric cars need power. This can result in failures or voltage drops.
To avoid this, network operators should consider designing and implementing smart solutions, such as energy management systems (EMS). They distribute the load over time, for example by charging vehicles at night. Another very important task is the modernization of the energy infrastructure, including the expansion of transformer stations and transmission lines. This will allow us to meet the growing demand, especially since electric vehicles will soon become an increasingly common sight on our roads. We cannot forget about the huge importance of renewable energy sources. Equally important here are energy storage facilities that store electrical energy. It can be used later. Such batteries are invaluable, as are charging stations for electric cars .
How to properly design an electrical installation for vehicle charging?
Everything indicates that electric cars may become commonplace in some time. Manufacturers of electric cars are creating increasingly innovative projects, improving the components in such cars, including the electric engine, but not only. Considering that we will also invest in such a vehicle, we should think in advance about the appropriate design of the electrical installation. Having such a car, we must remember that the main requirements of its operation are precisely regular charging.
When designing such an installation, we must consider several factors. One of the most important is determining the power of the car battery charger. Standard models offer power from 3.7 kW to 11 kW, but in the case of greater needs, when the car battery is larger, it is worth considering buying a charger with a power of up to 22 kW.
Another important aspect is to consider the possibility of expanding the installation in the future. This is especially a good solution when we will be using several electric vehicles. The cables must have an appropriate cross-section, consistent with the power requirements. Similarly, the cable for charging an electric car must be properly selected. Dedicated protections, especially differential circuit breakers, are equally important.
As we can see, there are many challenges, but the electrical networks and installations are constantly being improved. Renewable energy sources are also helping here, allowing for greater energy independence. Everything seems to be on the right track.
