EV Home Charging Station Buyer's Guide

You've decided on an electric car, but a key question remains: what's the most efficient and safest way to charge it at home? The range of charging solutions is vast, and technical terms like charging power, load management, or RFID can be confusing. This article serves as a practical guide to help you understand how home charging stations work and make an informed decision that suits your vehicle and home setup.

As your Joybuy Product Recommendation Officer, I have compiled the relevant information and product features to give you a clear overview of the available options.

What to Look for When Choosing a Charging Solution

The right choice of charging station depends on several technical and practical factors. Here are three key aspects you should consider.

Charging Power: 11 kW or 22 kW?

Charging power, measured in kilowatts (kW), determines how quickly your vehicle's battery charges.

• An 11kW wallbox is the most common and often the most practical solution for most private homes. It provides three-phase charging at 16 amps and can easily fully charge an average EV overnight. In Germany, these charging stations simply need to be registered with the grid operator.
• A 22kW wallbox offers double the charging power, reducing charging time accordingly. However, its installation requires approval from the grid operator, and not every electric car can accept the full 22 kW of alternating current (AC). Furthermore, the required electrical work in your home can be more complex.

Smart Features for Greater Convenience and Control

Modern charging stations offer much more than just power. Smart features can simplify daily use and help optimise costs.

• A smart wallbox with an app allows you to control and monitor the charging process from your smartphone. You can schedule charging sessions to take advantage of cheaper off-peak tariffs, adjust the charging power, and view your charging history.
• A wallbox with RFID (Radio-Frequency Identification) provides simple access control. Only authorised users with a corresponding card or fob can start a charging session. This is particularly useful if the wallbox is installed in a shared area (e.g., the underground car park of an apartment building).
• A wallbox with load management is essential for households with multiple high-consumption appliances or several EVs. Dynamic load management measures the home's total power consumption and automatically adjusts the vehicle's charging power to prevent overloading the main electrical connection.

Stationary Wallbox or Mobile Charging Cable?

The choice between a permanently installed and a mobile charging solution depends on your usage patterns.

• A permanently installed EV home charging station is the standard solution for homeowners. It is securely mounted on a wall, typically offers higher charging power, and is designed for daily use.
• A mobile Type 2 charging cable, often called a portable Schuko charger, plugs into a standard household socket (Schuko). It offers maximum flexibility for travel or as an emergency charger. However, its charging power is limited to a maximum of 3.7 kW, resulting in significantly longer charging times.

Our Charging Recommendations

Here is a selection of products with different features, covering various use cases.

dé Wallbox Type 2 11kW with APP & RFID

Why it stands out: This model combines the 11 kW charging power common in Germany with the most sought-after smart features, such as app control and RFID access control.

Advantages:

• 11 kW Charging Power: Three-phase charging at up to 16 A, suitable for most home applications.
• Smart Control: Manage via the Tuya Smart app to schedule charging, adjust power, and control remotely.
• Access Control: Two RFID cards are included to restrict use to authorised individuals.
• Integrated Safety: A Type B RCD (AC 30mA + DC 6mA) is already built-in, which can reduce installation costs.
• Long Cable: The 7.5-metre cable offers great flexibility for parking in a garage or driveway.

Who is it for? For homeowners looking for a balanced, secure, and smart 11kW wallbox for daily use who value convenience features like app control and access restriction.

feyree EV Charger Type 2 22kW with Dynamic Load Management

Why it stands out: This wallbox delivers high charging power of up to 22 kW and features dynamic load balancing (DLB) to prevent overloading your home's electrical system.

Advantages:

• Dynamic Load Management: Automatically adjusts charging power based on the household's current electricity consumption to protect the main connection.
• High Charging Power: Adjustable power up to 22 kW (32 A) for very fast charging, provided it's supported by the vehicle and grid connection.
• App Functionality: Remote control and monitoring via the Tuya app.
• High Protection Rating: With an IP66 rating, the wallbox is dust-tight and protected against powerful water jets, making it suitable for unprotected outdoor installation.

Who is it for? For users with a high-capacity electrical connection who want to install a 22kW wallbox (which may require approval). Ideal for households with multiple electric vehicles or other power-intensive appliances where smart load management is necessary.

dé Type 2 Schuko EV Charger with APP (Mobile Charging Cable)

Why it stands out: As a mobile Type 2 charging cable, this solution offers maximum flexibility. It requires no permanent installation and can be used with any standard Schuko socket.

Advantages:

• Plug-and-Play: Simply plug into a 230V household socket to charge your vehicle.
• App Control: The charging current (6–16 A) can be adjusted via the app to avoid overloading the socket.
• Universal Compatibility: Compatible with all EVs and plug-in hybrids that use a Type 2 EV charger connector.
• Portable: Ideal for travelling, visiting friends, or as an emergency solution when a wallbox isn't available.

Who is it for? For renters who cannot install a wallbox, owners of plug-in hybrids with smaller batteries, or as a secondary charger for on-the-go use. Also great for EV drivers looking for a cost-effective and flexible backup solution.

Frequently Asked Questions (FAQ)

Does an 11kW wallbox need to be registered in Germany?

Yes. According to § 19 of the German Low-Voltage Connection Ordinance (NAV), every charging device for electric vehicles must be registered with the responsible grid operator before it is commissioned. This also applies to an 11kW wallbox. The registration is typically handled by the certified electrician performing the installation.

What is the difference between an 11kW and a 22kW wallbox?

An 11kW wallbox charges at up to 11 kilowatts (three-phase, 16 A) and can fully charge most EVs overnight. A 22kW wallbox (three-phase, 32 A) charges twice as fast but requires approval from the grid operator and a suitably rated home electrical system. Additionally, the AC charging capacity of many vehicles is limited on the car's side to 11 kW.

Does every wallbox fit every electric car?

In Europe, the Type 2 connector (as per IEC 62196-2) has become the standard for AC charging. Therefore, virtually every modern EV home charging station with a Type 2 connector is compatible with almost all current battery electric vehicles (BEVs) and plug-in hybrids (PHEVs) on the market.
