Bi-directional EV Charger

Buy your bi-directional EV Charger at the best price

Here you'll find our selection of bidirectional charging stations, an innovative solution for optimizing the use of your electric vehicle. These stations not only allow you to recharge your battery, but also to return the stored energy to power your home (V2H) or feed it back into the grid (V2G).

Ideal for maximizing self-consumption of solar energy and reducing your energy costs, these stations combine performance, intelligence, and compatibility with various electric vehicle models. Choose from our models suitable for both individuals and businesses.

Why choose a bi-directional EV charger?

As you know, a solar panel is an essential piece of equipment for powering your home with green energy. By charging your electric car during the day with solar energy, you can use it for your energy needs in the evening, ensuring you'll have enough range to get to work the next day.

Optimize your energy consumption
With a bidirectional EV Charger, your electric car becomes a mobile battery. You can store energy when electricity is cheaper (or via your solar panels) and use it during peak consumption times to reduce your bill.

Take advantage of V2H (Vehicle-to-Home) technology
Power your home with the energy stored in your electric vehicle, reducing your dependence on the grid and maximizing the self-consumption of your solar production.

Contribute to grid stabilization with V2G (Vehicle-to-Grid)
Some EV Chargers allow excess energy to be injected into the grid, which can be leveraged through electricity resale or grid support programs.

Secure your power supply
In the event of a power outage, your vehicle can serve as a backup power source for your essential equipment.

Anticipate the future of electric mobility
Bidirectional EV Chargers are part of the energy transition and are gradually becoming standard, offering long-term economic and ecological benefits.

🔋 Investing in a bidirectional EV Charger means choosing smart and sustainable energy management.

How to choose your bidirectional EV charger?

Choosing a bidirectional EV Charger depends on several technical and economic criteria. Here are the main elements to consider, along with concrete figures:

Compatibility with your vehicle

Not all electric cars support bidirectional charging. Currently, some models, such as the Renault 5 and the KIA EV6, support V2G (Vehicle-to-Grid) or V2H (Vehicle-to-Home) technology, primarily via the CHAdeMO standard. The CCS standard is beginning to integrate this functionality, but remains less widespread. Always check your vehicle's compatibility before investing.

Charging and Discharging Power

The power of a bidirectional station directly influences the charging speed and the amount of energy you can return.
- Charging power: between 7 kW and 22 kW in alternating current (AC) or up to 50 kW in direct current (DC). - Discharge power (V2H/V2G): generally 3.7 kW to 10 kW, which can power an entire house for several hours.

Example: A 10 kW bidirectional EV Charger can power an average household consuming 2 kW continuously for approximately 5 hours with a 50 kWh battery.

Features and smart energy management

The most advanced bidirectional EV Chargers incorporate features to optimize energy management:
✔ Time-based programming to take advantage of off-peak hours, when electricity costs 30 to 50% less.
✔ Real-time monitoring via a mobile app, with consumption and grid feed-in statistics.
✔ Connection with solar panels: For example, a 6 kWp solar installation can generate up to 8,000 kWh/year, some of which can be stored in the car and reused in the evening.

Standards and Certifications

A EV Charger must comply with certain safety and performance standards:
- ISO 15118: communication protocol for smart charging and bidirectionality.
- CE and IEC 61851 standards: compliance with European standards for EV charging.
- Electrical safety: protection against overvoltages and short circuits.

Installation and compatibility with your electrical network
- Required voltage: some EV Chargers operate on single-phase (230V) and others on three-phase (400V).
- Required circuit breaker: a 7 kW EV Charger requires a 32A circuit breaker, while a 22 kW station may require up to 40A three-phase.
- Installation cost: installing a bidirectional EV Charger generally costs between €1,500 and €3,500, depending on the complexity of the work.

Budget and Profitability

The price of a bidirectional EV Charger ranges from €4,000 to €8,000, or two to three times more expensive than a conventional station. However, this expense can be offset by:
- Energy savings: By charging during off-peak hours (€0.12/kWh) and consuming stored energy during peak hours (€0.25/kWh), a station can generate savings of up to €400-600 per year.
- V2G revenue: By participating in network support programs, you can resell electricity and receive financial compensation of €200 to €500 per year, depending on the rates applied by your supplier.
