How to choose a Wallbox?

If you're planning to buy an electric car, you probably want to be able to charge it at home. You may have heard that it takes hours. Now it's time to check how to choose a fast charger for an electric car - a Wallbox.

In this article, you'll find out:

1. What is a Wallbox?
2. Tips on choosing the right Wallbox.
3. How long does it takes to charge a car battery?

It's important to note that you can charge electric and plug-in hybrid cars at home. It allows you to mainly use electric power for short city trips, cutting emissions to zero and saving on fuel. These are just a couple of the many reasons why getting a home electric car charger is a good idea.

Wallbox - what is it?

This device is designed to be installed in homes, typically in garages, and occasionally on driveways or near parking spaces. In simple terms, a Wallbox is essentially a fast charger designed for electric cars and plug-in hybrids. Depending on the desired power capacity and installation options, the Wallbox can be connected to the existing electrical network or set up on a dedicated circuit, often with a separate current meter.  Get to know the distinctive features of home AC chargers to select the one that suits your needs best.

Wallbox - how to choose? 

Choosing a Wallbox involves considering several main parameters, including:

• Power (kW):

The power rating, measured in kilowatts (kW), directly impacts the charging time of an electric car. The Wallbox's power is determined by its structure and the type of connection.

• Type of Connection:

Wallboxes come in single-phase (230V) or three-phase (400V) installations (higher voltage results in greater device power). However, not all homes have a three-phase wiring. Consider making additional connections or planning for it during the project phase, such as when constructing a garage.

• Fuse Strength:

Fuse strength is specified as 10A, 16A, or 32A and depends on the connection power outlined in the contract with the energy supplier. A higher amperage fuse allows the Wallbox to deliver more charging power. It's usually possible to request an increase in connection power from your energy supplier.

• Plug Model:

The type of plug depends on your electric car or hybrid's socket. Most commonly, it will be a Type 2 plug. You will find many adapters on the market that allows charging car with other type of connector (such as Type 1).

Understanding and considering these factors will help you choose a Wallbox that aligns with your electric car's requirements and your home's electrical setup.

 

The charging time of an electric car is relianted to the power of the charger. When using a standard cable with a plug and activating the factory charger in your vehicle or its portable equivalent, you typically have a maximum power of around 3 kW. Charging a Nissan Leaf with a 40 kWh battery from zero to 100% in this way takes over 12 hours. Enter the fast charger – the 22 kW Wallbox. Thanks to this upgraded device, the same Nissan Leaf can be fully charged in less than two hours. However, it's important to note that such high-power Wallboxes require a three-phase installation with a 32A fuse. Even less powerful home chargers, like those with 7.2 kW, can significantly reduce charging time. For instance, it takes about 5.5 hours to charge the Nissan Leaf with such a device.

These examples underscore the advantages of investing in a Wallbox. To estimate your electric car's charging time more precisely, use a simple charging time calculator.
 

Let's summarize the key points:

1. Choosing Charging Power:

• Selecting the right charging power depends on your home's technical conditions. Ensure you know the available connection power and consider other factors like cables and additional protection.

2. Price Differences:

• The variations in Wallbox prices stem from additional features like mobile app integration, charger sharing capabilities, and overall craftsmanship. Quality wallboxes typically start around PLN 2,500 gross and can go up to PLN 7,000.

3. Installation by an Electrician:

• Set-up usually involves attaching it to the wall and connecting it to the socket. While basic installation might not require an electrician, it is recommended to hire a professional for a secure and reliable installation.

4. Mobility of Wallbox:

• Standard Wallboxes are stationary chargers. However, there are mobile solutions, such as the high-power PocketBox Pro from Green Wallbox. With a charging power of up to 16kW, it's compact and portable, suitable for travel, and comes with interchangeable adapters for charging from various sockets.
