Power Management
Dynamic Load Balancing
Your main fuse has a limit. When you charge your EV while running appliances, you risk overloading the circuit. Load Balancing monitors consumption in real-time and adjusts charging to stay safe.
- Monitors main fuse via wireless meter
- Reduces charging when demand is high
- Peak Shaving to avoid demand taxes
- Prevents circuit breaker trips
- Resumes full speed when available
Power Management
Solar Balancing
Use your own solar energy before it goes to the grid. The charger monitors your solar production and adjusts charging to maximize self-consumption. Free energy from your roof, straight to your car.
- Uses excess solar production first
- Reduces grid feed-in (avoids costs)
- Charges when your panels produce
- Works with any inverter brand
Power Management
Power Sharing
Split available power across multiple chargers intelligently. When one car finishes, others get more power. Perfect for homes with multiple EVs or small parking facilities.
- Dynamically distributes available power
- Automatically rebalances as cars connect and disconnect
- Balances across all connected chargers
- No need for expensive grid upgrades
Power Management
Phase-Aware Charging
In 3-phase installations, unbalanced loads can cause issues. Phase-Aware Charging distributes power evenly across L1, L2, and L3 phases, maximizing throughput while keeping the system stable.
- Monitors all three phases independently
- Prevents single-phase overload
- Maximizes available capacity
- Required for some utility contracts
Tariff Management
Dynamic Tariff Charging
With dynamic energy contracts, prices change every hour. Plugchoice fetches the next day's prices and schedules your charging during the cheapest windows. Set your departure time and let the system optimize.
- Fetches day-ahead prices automatically
- Schedules charging in cheapest hours
- Automatic mode
- Works with all European energy providers
Tariff Management
Scheduled Charging
Not on a dynamic contract? Set fixed time windows for low-rate charging. Perfect for night tariffs or employer-subsidized charging windows.
- Avoid high tariffs
- Set custom time window
- Override for urgent charging
- Simple setup in the app
Smart Charging FAQ
Why is Plugchoice free?
Plugchoice is made by Volt Time. We earn revenue from selling hardware. The platform exists to make our chargers more valuable, not as a profit center itself.
Some features like Solar Balancing and Dynamic Load Balancing are available as optional one-time purchases. Basic smart charging remains completely free.
Can I switch between 3-phase and 1-phase for Solar Balancing?
One Pro can dynamically switch between 3-phase and 1-phase charging for more efficient solar utilization, maximizing your solar self-consumption. Coming soon.
Our other chargers operate on a fixed phase configuration. They still support Solar Balancing, but without dynamic phase switching.
Do you support V2G (Vehicle-to-Grid)?
One Pro features ISO 15118-20 support, preparing you for bidirectional charging as the technology becomes more widely available and vehicle manufacturers enable it. Coming soon.
While V2G is still emerging, investing in V2G-ready hardware ensures you're prepared when your vehicle and grid support it.
Does it work with my solar panels?
All of our chargers support Solar Balancing with any brand of solar panels. We meter your main fuse, not the panels themselves, because what matters is excess solar power available.
Our chargers work with P1 port meters, CT clamps, and various EMS integrations to measure real-time energy flow.
Can I integrate with my smart home?
Plugchoice offers a REST API that lets you integrate any of our chargers with your smart home system, home automation, or custom applications.
Integration with Home Assistant, OpenHAB, and other popular smart home platforms is possible through our open API.
Which billing platforms do you support?
Plugchoice's Proxy feature connects your charger to any OCPP-compatible billing platform. No limitations, no vendor lock-in.
Whether you're using a regional provider or a global solution, we've got you covered. One charger, infinite possibilities.
Are there monthly subscription costs?
Basic charger management through Plugchoice is completely free. Monitor your sessions, manage your charger, all at zero cost.
Advanced features like Solar Balancing and Dynamic Load Balancing are available as a one-time purchase. Pay once, use forever.
Does Plugchoice work with other charger brands?
Plugchoice works with all OCPP-compatible chargers at no cost. You're not limited to Volt Time hardware. We believe in open standards.
Third-party chargers get access to session monitoring, usage statistics, and billing platform integration. Some advanced features may require Volt Time hardware.
