Frequently asked questions
We understand that choosing your first wallbox or charging station can be a bit of a puzzle. What should you keep in mind when choosing, and how do you specify your requirements? A well-chosen wallbox will last and serve you for many years. With the right choice, you can save a great deal of money.
Below you will find the most common questions our customers ask us.
If you cannot find the answer or would like help with your choice, do give us a call or drop us a line.
We want a wallbox for our company
Yes, the word wallbox has become the accepted term for charging stations. More precisely, it is a charging station mounted on a wall. Many retailers offer it in this form. Do you actually have the option of mounting the charger on a wall at your premises? If so, you can choose from our wallboxes e:car WALL PRO, e:car DC WALL, or alternatively e:car WALL, which are better suited to private use, though use at a business is not ruled out. It depends on how they are used and on your requirements.
How much does a wallbox cost?
Although they may look similar, their prices can vary considerably. Our wallboxes are available from 14,900 CZK excluding VAT for a wallbox with a single charging point in the form of a socket in the BASIC variant, while a wallbox with two charging points in the form of a socket can be had for 58,000 CZK excluding VAT, as this is already a professional charging station with billing metering, compliant with both Eichrecht and AFIR, which can be operated as a public or semi-public station.
What are the requirements for the supply cable?
We are asked this question very often, and it is not entirely straightforward to answer. We need to know:
- how many charging points (how many cars will be charged at once),
- how far the charging station will be from the distribution board,
- what power output you will be charging at,
- kudy kabel povede,
- are you planning more stations in the future?
For home wallboxes, charging stations with an output of up to 22 kW, a 5 × 6 mm² cable (CYKY-J 5x6) is used for a length of up to approximately 30 m
For longer distances: 5 × 10 mm² (to minimise voltage drop and overheating of the wiring)
What protection do we need?
When designing the protection for various options of charging electric vehicles via a wallbox, the total power output must be taken into account.
A residual current device (RCD) is integrated into all of our charging stations.
Below are the protection options for the most common charging scenarios:
1) Charging one car at 11 kW (3×16 A)
2) Charging one car at 22 kW (3×32 A)
3) Charging two cars simultaneously at 2×11 kW (3x32 A)
Note: The SMART and PREMIUM wallboxes feature dynamic load management, so the protection can be dynamically adjusted to suit the available capacity of the main circuit breaker.
