Charging Station Assistance:
A Complete Guide and Documents

Parking Location: Private, with limited access for outsiders. Examples include parking near a private house, townhouse wall, garage, or designated spots in an underground parking lot.

Connector Type: Depends on the electric vehicle. If known in advance, the most convenient choice is an integrated cable that can be hung on the station or placed on a nearby hook. The connector-pistol simply inserts into the holster.

Identification: Optional. Usually not required since all potential users are family members, guests, etc. However, for underground parking lots, customers sometimes request stations with RFID card identification.

Installation Location: Indoor or outdoor. When choosing a charging station, it is important to pay attention to the dust and moisture protection class (details at the end of the article).
Mounting Type: Typically wall-mounted (wallbox), but sometimes they can be installed on poles.

Parking Location: Mobile and accessible anywhere. Examples include charging on the road, in your driveway, at public parking lots, etc.

Connector Types: A variety of connectors are available depending on the electric vehicle. Typically, universal connectors are used, compatible with various electric vehicle models.
Identification: In most cases, no identification is required as portable chargers are designed for personal use.

Installation: No installation is needed as portable charging devices can be used wherever there is access to an electrical outlet.

Placement: Portable chargers do not require permanent installation and can be easily carried around, providing mobility and convenience in their usage.

Parking Location: Exclusive closed parking lots for company vehicles, closed condominiums, company car parks, employee-only parking areas, etc.

Connector Types: Usually predetermined and known in advance. An ideal choice is an integrated cable with a connector that can be easily hung on the charging station or a nearby hook. The connector-gun is simply inserted into the holster.

Identification: Depending on the situation, identification may be required. Sometimes, for underground parking lots, clients order stations with RFID card identification.

Installation: Suitable for indoor or outdoor locations. When choosing a charging station, it's important to consider the protection class against dust and moisture (details at the end of the article).

Placement: Typically installed as wall-mounted (wallbox) units, but occasionally can be placed on poles.

Electric vehicles can consume substantial energy, posing a risk of overloading your electrical system. To prevent this, ensure the charging station's power matches or slightly falls below the maximum supply capacity. Also, consider other connected consumers.

For instance, imagine a dedicated 220 V line meant for charging two EVs at home, with a 32 A circuit breaker.
The power calculation is: 220 V * 32 A = 7 kW.

Installing two 7 kW charging stations, both operating simultaneously, could overload the network, triggering the circuit breaker. Solutions? Choosing two 3.5 kW chargers or investing in a station tailored for dual EV charging are options to consider. These stations distribute power efficiently, granting the full load to one EV and equally dividing it when both are in use.

When choosing an electric charging station, it is important to consider the power capacity of the onboard charger for alternating current, if the type of electric vehicle is known (e.g., it is your personal transport).
Example: For instance, Nissan Leaf electric vehicles are known to have a small onboard charger with a power capacity of 3.5 kW in the early models. This means it won't require more than this power. When selecting a home charging station and allocating a separate power line, it should be based on this lower figure. If the model of the electric vehicle is unknown, one can assume it can accept any available maximum power capacity. For example, Tesla has two types of onboard chargers - a standard one at 11 kW and a Dual Charger at 22 kW.

Regarding individual preferences, it is quite simple - the faster the charging at home, the better! Here are a few options:

1. Station with a fixed power capacity of 3.5 kW or 5 kW (corresponding to currents of 16 or 25 A). In this case, one needs to monitor other electrical devices in the house to ensure that other power-hungry appliances (washing machines, heaters, etc.) are turned off during vehicle charging.
2. Station with a fixed maximum power capacity of 7 kW and the vehicle charging through a timer, for example, at night when all other consumers are turned off. Such charging timers are usually available in most electric vehicles.
3. Station with adjustable charging power (for example, with settings of 1.44 kW, 1.8 kW, 3.6 kW, 5.4 kW, and 7.2 kW) to find the optimal charging power for the electric vehicle based on specific needs.
4. Charging station with balancing function that automatically adjusts the charging power based on the total consumption on the line (this would require a current sensor to be installed at the entrance of the house). For example, if you turn on an iron or boiler, the charging of your electric vehicle will slow down, but when household members go to bed and everything else is turned off, the full power will be dedicated to charging the electric vehicle. This is an ideal solution for households with only one phase of power supply and several consumers connected to it.

Wallbox smart mini 32A, 7kW (Voltage 230V AC ±10%):
Best suited for home conditions when you have three phases at 220 V and a current limit of 32 A on each phase. Ideal for overnight charging when the car is parked and can be charged in 7 hours.
Examples:

• Nissan Leaf with a 40 kWh battery will charge in approximately 6-7 hours.
• Renault Zoe with a 41 kWh battery will charge in approximately 6-7 hours.

Wallbox smart mini 16A, 11kW, Voltage 380V AC ±10%):
Great for homes or places with a three-phase power supply. Due to higher power, charging is faster, making it a good option for cases where you need to charge the car in a short time.
Examples:

• BMW i3 with a 42 kWh battery will charge in approximately 3-4 hours.
• Volkswagen ID.3 with a 58 kWh battery will charge in approximately 4-5 hours.

Wallbox smart mini 32A, 22kW, (Voltage 380V AC ±10%):
Suitable for places with a three-phase power supply and high energy requirements. This is an excellent choice for commercial use or situations where fast car charging is needed.
Examples:

• Tesla Model 3 Long Range with an 82 kWh battery will charge in approximately 3-4 hours.
• Audi e-tron with a 95 kWh battery will charge in approximately 4-5 hours.

When choosing a charging station for an electric vehicle, you may come across the designation "IP."

IP rating (Ingress Protection Rating) is a classification of the protection level of electrical equipment enclosures against moisture, water, dust, and other solid objects. It adheres to international standards such as IEC 60529 (DIN 40050, GOST 14254-96).

The first digit (protection against solid particles):
0 — no protection
1 — protection against objects greater than 50 mm in size
2 — protection against objects greater than 12.5 mm in size
3 — protection against objects greater than 2.5 mm in size (commonly used for tools and cables)
4 — protection against objects greater than 1 mm in size (wires, precision tools)
5 — protection against dust in amounts that do not interfere with the device's functionality
6 — complete protection against dust
The second digit (protection against liquids):
0 — no protection
1 — protection against vertically falling drops (e.g., condensation)
2 — protection against falling drops at an angle up to 15° from the vertical
3 — protection against water sprays at an angle up to 60° from the vertical, including rain
4 — protection against splashes from all directions
5 — protection against directed water jets from any direction
6 — protection against the entry of water acting like waves
7 — protection against water immersion up to 1 meter
8 — protection against prolonged water immersion under pressure

Using this information is straightforward. On electric vehicle charging stations or in accompanying documentation, you will find the IP protection class indicated (e.g., IP64). Applying the data above, you can decode this: the enclosure is fully protected against dust and rain, making it suitable for outdoor installation. Conversely, a similar station with IP54 should be installed under a roof.
