Electromobility is becoming increasingly popular, and electric cars constitute a growing share of the car market. With the rising number of electric vehicles, the question of charging has become a key aspect. Electric car users can charge their vehicles in different places: at street charging stations and at home. Each of these options has its unique characteristics, advantages, and disadvantages. In this article, we will discuss the differences between street and home charging and analyze technical, economic, and practical aspects.
The first key difference between street and home charging is the types of chargers available. Street chargers often offer higher power and charging speeds compared to home installations. Typical street chargers can be divided into two main types: fast chargers (DC) and slower chargers (AC). Fast chargers can deliver up to 350 kW, allowing the battery to charge up to 80% in just a few tens of minutes. Slower AC chargers, while less efficient, are also used in public parking lots and workplaces.
Home chargers are mainly AC units that usually offer power from 3.7 kW to 22 kW. However, the most popular ones are chargers with a power of 7.4 kW, which enable an average electric car to be fully charged overnight. The choice of the right home charger depends on available energy resources and the user’s needs.
Installing a street charger is significantly more complicated than installing one at home. This requires advanced energy infrastructure, necessary permits, and cooperation with local energy providers. The process is usually carried out by specialized companies and managed by local authorities or private operators.
Installing a home charger is much simpler and can be performed by a licensed electrician. This requires proper electrical installation at home but does not involve as complex procedures as street chargers. In many cases, it is only necessary to adapt the existing electrical installation and mount a dedicated charging unit.
The costs associated with street and home charging vary significantly. Installing a street charger is an expensive project that includes the purchase of the unit itself, installation work, and connection to the power grid. Additionally, operators of such chargers must consider infrastructure maintenance costs and any licensing fees.
The cost of installing a home charger is significantly lower, although it also requires investment. The average cost of purchasing and installing a home charger ranges from a few thousand to several tens of thousands of kroner, depending on the unit’s power and the specifications of the home’s electrical installation. In the long run, using a home charger is more economical because the cost of electricity used at home is usually lower than the price per kWh at public charging stations.
The cost of electricity varies depending on the charging location. At public charging stations, prices can be significantly higher, especially for fast chargers. Operators of such stations charge for minutes of charging, per kWh, or a combination of both, making the total charging cost relatively high.
For home charging, the cost of electricity is tied to the tariff offered by the energy provider. Many households use variable tariffs that offer lower electricity prices at night, further reducing charging costs. Some countries also offer special tariffs for electric car owners, providing even greater savings.
One of the most important factors influencing the choice of charging location is availability and convenience. Street charging offers greater flexibility because chargers are located in various places such as shopping centers, municipal parking lots, and gas stations. This allows the vehicle to be charged during daily activities, which is especially beneficial for people living in cities.
Home charging, on the other hand, provides the highest level of convenience because it allows the vehicle to be charged at any time without having to leave home. This is particularly important for people who have their own garage or parking space with access to a power outlet. Charging at night, when the car is not in use, provides a full charge for the next day, eliminating the need for frequent visits to public charging stations.
Charging time is another important factor that distinguishes street from home charging. Fast chargers can charge the vehicle to 80% in a few tens of minutes, which is an ideal solution during longer trips. Slower AC chargers, both on the street and at home, need more time to fully charge the battery.
For home charging, the charging time mainly depends on the power of the installed charger and the vehicle’s battery capacity. The average charging time ranges from a few hours to overnight, which is acceptable if charging occurs at night. For people who need faster home charging, higher power chargers are available, which can significantly reduce charging time.
Charging safety is a key aspect, both for street and home charging. Public charging stations are usually equipped with advanced safety systems that protect against overload, short circuits, and other dangerous situations. Operators of these stations also ensure regular inspection and maintenance of the equipment, ensuring reliability.
Home chargers must also meet specific safety standards. It is important that the installation is carried out by a qualified electrician to ensure proper protection and minimize the risk of failure. It is also worth investing in a charger with monitoring and control features, allowing real-time tracking of the charging process and quick response to any problems.
In summary, both street and home charging have their unique characteristics, advantages, and disadvantages. Given the convenience, cost savings, and flexibility, the optimal choice for most electric vehicle users is a home charger.
