EV Charging: Imagine this scenario- It’s 7 PM on a winter evening in Berlin. While your neighbors worry about rising electricity costs, you’re watching TV, cooking dinner, and running the heating – all powered by your Volkswagen ID.4 parked in the garage. This isn’t science fiction; it’s Elli’s groundbreaking bidirectional charging pilot that’s turning every electric vehicle into a mini power plant.

EV Charging : The Game-Changing Technology
What Makes Bidirectional Charging Revolutionary?
Think of your EV battery as a massive power bank – one that can store energy when it’s cheap and abundant, then feed it back to your home when you need it most. Volkswagen Group’s subsidiary Elli has cracked the code on making this seamless, legal, and incredibly profitable for homeowners.
The magic happens through an 11 kW bidirectional DC charger developed with partner CUBOS. It’s like having a smart energy butler that knows exactly when to charge your car and when to use that stored energy to power your home.
The Numbers That Will Transform Your Bills
| Benefit | Impact | Savings |
|---|---|---|
| Charging Cost Reduction | Up to 75% lower | €150-300/month typical |
| Energy Independence | Solar + EV storage | 80%+ self-sufficiency |
| Grid Trading Revenue | Sell excess power | €50-150/month potential |
| Total Monthly Impact | Combined savings | €200-450/month |
How Your Daily Life Changes
Morning: Energy Flows In
Your EV charges overnight when electricity rates are lowest, storing both grid power and excess solar energy from your rooftop panels. It’s like shopping for energy when everything’s on sale.
Evening: Your Car Powers Your Life
As you arrive home, your vehicle seamlessly switches from transportation mode to home power station. The Elli Charging app orchestrates this energy dance – no manual intervention required.
Night: Smart Optimization
While you sleep, the system analyzes tomorrow’s weather forecast, energy prices, and your driving schedule to optimize when to charge and when to discharge.

The Application Process
Elli is actively recruiting pioneer families who want to be first adopters of this revolutionary technology. Selected participants receive the bidirectional charger and become part of a historic shift in how we think about energy and transportation.
The Bigger Picture: Europe’s Energy Future
Managed Battery Network (MBN) Vision
By 2026, Elli plans to connect hundreds of EVs into a virtual power plant operating across the European Power Exchange (EPEX). Imagine thousands of electric vehicles working together as a massive, distributed battery system – stabilizing renewable energy and creating income for owners.
Giovanni Palazzo, Elli’s CEO, perfectly captures the vision: “We’re bridging the gap between mobility and energy.”
Real-World Impact Stories
The Solar-EV Synergy
Picture the Schmidt family from Munich: Their rooftop solar generates 15 kWh during peak sun hours, but they only use 3 kWh during the day. Instead of selling excess power to the grid at low rates, their ID.5 stores it. Come evening, that free solar energy powers their home while neighbors pay premium electricity rates.
Grid Stabilization Benefits
During renewable energy surges, your parked EV helps absorb excess power. When demand peaks, it feeds energy back. You become an energy entrepreneur, earning money while supporting Germany’s green transition.
The Elli PowerCenter: Industrial-Scale Innovation
Complementing the home program, Elli’s new Salzgitter facility will feature 20 MW capacity and 40 MWh storage, using PowerCo’s LFP battery technology. This industrial backbone supports the residential revolution.
Why This Matters Now
Perfect Timing Convergence
Three trends are colliding to make bidirectional charging unstoppable:
- Solar adoption surge: More homes generating excess energy
- EV battery improvements: Larger, longer-lasting batteries
- Energy price volatility: Growing need for cost predictability
Your Next Steps
Ready to transform your EV from transportation tool to energy asset? The pilot program represents just the beginning of a fundamental shift in how we power our lives.
The future of energy isn’t just renewable – it’s mobile, intelligent, and parked in your garage.
Will your next car be just transportation, or will it be your home’s new power source?
