The Ultimate Guide to Installing an EV Charging Station at Home

The Rising Popularity of Electric Vehicles

With the shifting global focus towards sustainability, electric vehicles (EVs) are rapidly becoming a norm rather than a novelty, as they represent a vision of the future of transportation that is clean, efficient, and that uses cutting-edge technology.

Electric vehicles offer increasing performance features and a level of refinement that is seldom seen in even the most expensive internal combustion engine (ICE) vehicles. Silence combined with power makes these next-generation cars a testament to the advancements in automotive technology.

The European Parliament, in February 2023, deliberated on the potential ban of new petrol and diesel car sales from 2035. Although this initiative was not formally enacted in Germany, the discussions significantly highlighted the European Union's dedication to addressing climate change and promoting the uptake of electric vehicles.

The Need for Home EV Charging Stations

As electric vehicles grow in popularity, so does the demand for EV charging stations. After all, the convenience of refueling your car at home is an undeniable advantage.

But a home charging station is not just about convenience; it's also about control. You're not at the mercy of the availability of public charging stations or the uncertainty of their operational status.

Moreover, charging your electric vehicle at home can be more cost-effective compared to using public charging stations. By taking advantage of cheaper electricity tariffs and plans aimed at EV owners, you can further reduce your charging costs.

One of the lesser-known benefits of home charging is its positive impact on the battery's health. Public chargers can sometimes damage the battery due to rapid charging, which can cause the battery temperature to rise. Home charging provides a slower, more battery-friendly option that can help extend the lifespan of your EV's battery.

Finally, installing a home charger can increase the value of your property. Properties with installed EV chargers are highly sought-after by electric vehicle owners, making them sell or rent faster and at a higher price.

In the following sections, we will guide you through the process of installing an EV charging station at your home. With this guide, you'll be well-equipped to make an informed decision about installing a home EV charging station.

Planning and Preparation for Your Home EV Charging Station

Understanding Your Electrical Needs

Before you install an EV charging station, it's crucial to understand your electrical needs. A typical charging station must be installed on a dedicated line, with its own breaker coupled with its own differential switch. Here's how you can calculate the available power:

Single Phase Installation:

Take the amperage of your main breaker and multiply it by 230V. For instance, if your main breaker's amperage is 20A, the total power would be 4.6kW (20A x 230V = 4.6kW). Next, subtract the maximum power you consume instantaneously from this total to estimate how much power is left for your terminal.

1. Differential switch: Type A Hi, 30mA, 2P or 1P + N, 40A max
2. Breaker: Min. C curve, 3kA min., 2P or 1P + N cutoff, 16 to 40A (choose 3 to 8A in addition to the rated current of the terminal)
3. Current-Release Triggers: No special specifications

Three-Phase Installation:

For a three-phase installation, multiply the amperage of your main breaker by 400V.

1. Differential Switches: 4P 40A 30mA type B-EV, 400V
2. Breaker: Min. C curve, 3kA min., 2P or 1P + N cutoff, 16 to 40A (choose 3 to 8A in addition to the rated current of the terminal)
3. Current-Release Triggers: No special specifications

A three-phase circuit, with just one extra wire, provides nearly double the power of a single-phase circuit, delivering the same amperage more efficiently through smaller wires. It does not mean you personally should prefer a three-phase installation to a single-phase installation, keep in mind that technical characteristics should be taken into consideration. If you are unsure about the capacity of your house to handle an EV charger, you can always contact a specialist. Alternatively, some companies like Wallbox offer comprehensive charging solutions in packages, so you do not have to worry about which switch or breaker to choose.

Choosing the Right Location for Your EV Charging Station

The optimal location for your electric vehicle charging station could be your garage or an area near your parking spot. Keep in mind, the chosen spot should guarantee safety, offer protection from various weather conditions, and provide straightforward accessibility for your vehicle to connect.

Selecting the Right Charging Station Type and Equipment

The type of EV charging station can range from basic ones with standard safety features to high-end models with smart capabilities including remote monitoring and scheduling. The right type for you depends on your specific needs, budget, and the specifications of your electric vehicle. For instance, some electric vehicles come with a recommended type of home charging station, so be prepared in advance.

Installation Process

The installation of an EV charging station should be carried out by a professional electrician to ensure safety and compliance with electrical codes. Please, follow these steps for a successful installation:

• Inspection and planning: Hire a professional electrician who will examine your electrical system and plan the installation based on your home's layout and specific needs.
• Installation of the charging station: The electrician will mount the charging station, run the necessary wiring, and make the connections.
• Testing and demonstration: After installation, the electrician will test the charging station to ensure it's working correctly and show you how to use it.

Simple as it is, but remember to ensure your electrician follows the recommended electrical safety guidelines during installation.

Maintenance and Troubleshooting

Maintaining your EV charging station is important for its longevity and efficiency. Regularly inspect the charging cable for any signs of wear and tear and keep the charging point clean. In case of any issues, it's advisable to seek professional help.

Troubleshooting Common EV Charging Station Issues

A well-installed EV charging station should provide reliable service, but like all technical equipment, it might experience occasional issues. Should you encounter a problem, here are some steps you might follow:

1. Check the power supply: Ensure the power supply to the charging station is active and the circuit breakers are not tripped.
2. Inspect the charging cable and plug: Look for any visible damage to the cable or the plug. Do not use the charging station if you notice any damage.
3. Verify the charging station status: Many charging stations have indicator lights or a display showing their status. Refer to your charging station's user manual for interpreting these indicators.

In case of persistent problems, it's best to contact a professional for assistance: an electrician or a service provider. If your charging station was installed by Lade Express or Mobility House, they provide check-up services to help diagnose and fix any issues.
