Electric driving is on the rise, and more and more households are combining their electric car with solar panels. But to truly maximize your sustainable investment, a home battery is a smart addition. Why? A home battery combined with charging stations ensures that your produced solar energy is not lost, but is used in the most efficient way to charge your car. Moreover, with a battery, you can cleverly manage charging times, reduce peak load, and benefit from lower energy tariffs. As a result, electric driving becomes even more cost-effective and sustainable. In this blog, you will read exactly how a home battery improves your charging strategy, how to prevent peaks, and how to use power more wisely and cheaply—all with maximum control and comfort.

Smarter charging of your electric car with a home battery

One of the biggest advantages of a home battery in combination with a charging station is the ability to charge smarter. During the day, your solar panels generate electricity, but you are often not home to connect your car. Thanks to a home battery, this electricity is stored until you come home. This way, you charge your car mostly with self-generated, sustainable energy. You avoid having to purchase expensive electricity from the grid during peak hours. Especially if you have a dynamic energy contract, you can set smart software to charge your car at the cheapest moments. Your home battery then acts as a buffer between production and consumption, allowing you to save on your charging costs and reduce the load on the grid. This not only makes your wallet happy but also contributes to a more stable electricity network.

Peak flattening: why it's important for your charging situation

Peak flattening may sound technical, but in practice, it is very simple: it means flattening large peaks in your power consumption. Without a home battery, charging your electric car suddenly requires a lot of electricity from the grid, which can result in a high load on your connection. In some cases, you even have to upgrade your grid connection, with associated extra costs. A home battery prevents this problem by delivering extra power during charging. This way, you better distribute power consumption over the day and night. The benefits of peak flattening are:

• Preventing extra costs for upgrading your connection.

• Lower costs for grid management due to more stable consumption.

• More efficient use of self-generated solar energy.

• Less impact on the overloaded electricity network.

Especially if you want to charge multiple electric cars at home in the future, peak flattening with a home battery is almost indispensable.

How do you optimize your charging strategy with a home battery?

With a home battery, you can fully adapt your charging strategy to your lifestyle and energy tariffs. Smart charging stations and energy management systems ensure that you automatically charge at the most favorable moments. This works in three steps:

1. Store during the day: Your solar panels generate energy that you store in your home battery.

2. Smart planning: Through smart apps, you plan your charging sessions at times when electricity is cheap or readily available.

3. Efficient consumption: During charging, your car first uses the power from your home battery before relying on grid electricity.

With this strategy, you structurally lower your energy costs and improve your CO₂ footprint. Moreover, you enjoy the convenience of always having your electric car ready without having to worry about peak hours or expensive electricity.

What do you need to cleverly combine home battery and charging station?

Do you want to optimally benefit from the combination between a home battery and a charging station? Then you need a few important elements:

• Home battery with sufficient capacity (for example, 10 kWh or more, depending on your charging needs).

• Charging station that can intelligently communicate with your energy management system (Dynamic Load Balancing).

• Smart inverter or energy management system that controls generation, storage, and consumption.

• App or platform through which you easily set and manage charging times and battery usage.

By aligning these elements well with each other, you create a flexible, efficient, and sustainable energy system for your home and your car.

Why invest now in a home battery for EV charging?

The energy and mobility market is changing rapidly. With the phasing out of net metering, rising grid management costs, and pressure on the electricity grid, it becomes increasingly attractive to have control over your energy consumption. A home battery prepares you for a future where flexible charging and self-consumption of energy are essential. Moreover, you avoid surprises such as grid upgrades or high feed-in costs. By investing in a home battery, you make your charging solution smarter, cheaper, and more sustainable. Especially now that more and more charging stations support Dynamic Load Balancing as standard, you can make a big difference in costs and comfort with relatively simple steps.

Frequently asked questions about home batteries and charging stations

Can I connect my existing charging station to a home battery?
Yes, provided the charging station supports Dynamic Load Balancing or is connected via an energy manager.

How much extra can I save with a home battery for EV charging?
On average €300 to €600 per year, depending on your driving and charging pattern.

Is peak flattening mandatory with multiple EVs at home?
Not yet, but it prevents high costs for grid upgrades.

How much capacity do I need for one electric car?
At least 10 kWh is recommended for regular smart charging.

Can I charge during a power outage with a home battery?
Only if your home battery has a backup function.

Does charging with stored solar power really become cheaper?
Yes, mainly due to less dependence on more expensive grid electricity.

Is a smart charging station necessary when using a home battery?
Not required, but highly recommended for optimal control.

Can I expand the combination if I buy a second EV?
Yes, many systems are modularly expandable with extra batteries and charging points.
