With the increasing use of electric vehicles, the electrical infrastructure and project design of electric vehicle charging stations have also gained importance. For chargers to be installed in residences, complexes, hotels, gas stations, business centers, parking lots, or commercial establishments, simply mounting the device is not enough. It must also be evaluated whether the existing electrical installation can meet the power requirements of the planned charging devices.
Especially in facilities where multiple AC or high-power DC charging units will be installed, the existing contracted power and electrical infrastructure may be insufficient. In such cases, electrical power increase, kW upgrade, and facility capacity increase operations come into play.
A charging station electrical project involves designing the necessary electrical infrastructure to safely and appropriately connect the electric vehicle charging devices to be installed to the existing electrical facility.
The project evaluates supply lines, cable cross-sections, electrical panels, protection elements, grounding systems, and other necessary electrical arrangements, taking into account the power and number of charging devices.
For example, adding a 22 kW AC charger to an existing business does not require the same electrical infrastructure as installing multiple high-power DC fast charging units. As the total installed power of the charging station increases, the energy needs of the facility can also significantly increase.
The contracted power defined in a business's existing electricity subscription may not be sufficient to meet the additional load created by the charging stations to be installed.
For instance, if the existing facility is already using a significant portion of its capacity for production, air conditioning, lighting, elevators, machinery, or other electrical equipment, it may not be possible to directly add charging devices to the existing system.
In such cases, the existing facility loads and the planned charging stations are evaluated together to determine the new power required, and if necessary, an electrical power increase project is prepared.
One of the fundamental questions that needs to be answered before installing an electric vehicle charging station is:
"Is the kW value of the existing electricity subscription sufficient for the charging devices to be installed?"
For example, installing 2 units of 22 kW chargers at a facility can theoretically create an additional installed power of up to 44 kW. When the existing loads of the facility are added to this, the existing connection or contracted capacity may need to be re-evaluated.
Therefore, the kW upgrade for a charging station should be considered not only based on the nameplate power of the charger but also by taking into account the existing and planned total load structure of the facility.
The required power increase may not only mean changing the kW value in the subscription. Depending on the new power requested, the existing electrical infrastructure also needs to be checked.
Depending on the current situation, it may be necessary to increase the cross-section of the main supply cable, renew or enlarge the main distribution panel, replace protection elements, regulate the meter and measurement system, improve the grounding infrastructure, or evaluate transformer capacity.
Therefore, in charging station investments, examining the electrical infrastructure before purchasing devices can prevent capacity problems that may arise later.
The type of charging station directly affects the electrical project. There is a significant difference between the energy needs of low and medium power AC chargers and high power DC fast chargers.
Especially if DC charging systems of 60 kW, 120 kW, 180 kW, and above are planned to be installed, the existing electrical capacity of the facility needs to be evaluated in detail. If multiple fast chargers are installed at the same location, the total power required can reach hundreds of kW.
In such investments, options such as power increase, new connection capacity, or transformer power increase are evaluated technically and administratively when necessary.
The most sound approach in a charging station investment is to first determine the existing electrical infrastructure and current power, and then account for the number and power of the charging devices to be installed.
Thus;
existing power → charging station power requirement → necessary new capacity → power increase → electrical project → infrastructure implementation
a planned process can be established.
Especially in Antalya, for hotels, complexes, commercial businesses, parking lots, gas stations, and areas where electric vehicle charging station operations will be conducted, capacity planning, considering future charging units, is important for the sustainability of the investment.
An electric vehicle charging station electrical project is not just about running an electrical line to the charger. The adequacy of the existing electrical power, the total kW value of the devices to be installed, the main distribution system, cable and panel capacity, protection, and grounding arrangements must be evaluated together.
In facilities where the existing power is insufficient, it is necessary to establish the appropriate infrastructure after completing charging station power increase, electricity subscription kW upgrade, capacity increase, and necessary electrical project procedures.
Especially in facilities where multiple AC or high-power DC charging units will be installed, the existing contracted power and electrical infrastructure may be insufficient. In such cases, electrical power increase, kW upgrade, and facility capacity increase operations come into play.
What is a Charging Station Electrical Project?
A charging station electrical project involves designing the necessary electrical infrastructure to safely and appropriately connect the electric vehicle charging devices to be installed to the existing electrical facility.
The project evaluates supply lines, cable cross-sections, electrical panels, protection elements, grounding systems, and other necessary electrical arrangements, taking into account the power and number of charging devices.

As the total installed power of the charging station increases, the energy needs of the facility can also significantly increase.
Why Might a Power Increase Be Necessary for a Charging Station?
The contracted power defined in a business's existing electricity subscription may not be sufficient to meet the additional load created by the charging stations to be installed.
For instance, if the existing facility is already using a significant portion of its capacity for production, air conditioning, lighting, elevators, machinery, or other electrical equipment, it may not be possible to directly add charging devices to the existing system.
In such cases, the existing facility loads and the planned charging stations are evaluated together to determine the new power required, and if necessary, an electrical power increase project is prepared.
kW Upgrade for Charging Station
One of the fundamental questions that needs to be answered before installing an electric vehicle charging station is:
"Is the kW value of the existing electricity subscription sufficient for the charging devices to be installed?"
For example, installing 2 units of 22 kW chargers at a facility can theoretically create an additional installed power of up to 44 kW. When the existing loads of the facility are added to this, the existing connection or contracted capacity may need to be re-evaluated.

What Can Electrical Capacity Increase Cover?
The required power increase may not only mean changing the kW value in the subscription. Depending on the new power requested, the existing electrical infrastructure also needs to be checked.
Depending on the current situation, it may be necessary to increase the cross-section of the main supply cable, renew or enlarge the main distribution panel, replace protection elements, regulate the meter and measurement system, improve the grounding infrastructure, or evaluate transformer capacity.

Conclusion
An electric vehicle charging station electrical project is not just about running an electrical line to the charger. The adequacy of the existing electrical power, the total kW value of the devices to be installed, the main distribution system, cable and panel capacity, protection, and grounding arrangements must be evaluated together.
In facilities where the existing power is insufficient, it is necessary to establish the appropriate infrastructure after completing charging station power increase, electricity subscription kW upgrade, capacity increase, and necessary electrical project procedures.
