Load Sharing is Emporia's intelligent power management solution that allows multiple EV chargers to coordinate power delivery without exceeding electrical limits. Whether you have multiple chargers on a single circuit or spread across a dedicated EV sub-panel, Load Sharing automatically divides available power to ensure safe, efficient charging for all connected vehicles.
How Load Sharing Works
Load Sharing enables two or more Emporia EV chargers to automatically share available power from either:
Shared Circuit - Multiple chargers on a single circuit breaker (simplest setup)
Dedicated EV Sub-Panel - Multiple chargers on separate breakers within an EV-only sub-panel (maximum flexibility)
When multiple vehicles are connected, the chargers communicate through Emporia's cloud platform to dynamically divide available power, ensuring the total never exceeds 80% of your electrical capacity.
Compatible Chargers
Load Sharing works with:
Emporia Pro EV Charger
Emporia Classic EV Charger
No additional hardware or Vue monitor required.
Smart Power Distribution
When Charging Alone:
A single charger can use the maximum available power
When Charging Together:
Power splits automatically and equally among active chargers
The system guarantees a minimum of 6A per charger for safe operation
Power will begin to rebalance within 30 seconds of any load change (increase/decrease or start/stop of charging)
May take up to a minute or two to balance all chargers optimally
No manual management required
Example: Three Chargers on a 60A Circuit
With 48A available at 80% capacity:
All 3 charging: 16A each
2 charging: 24A each
1 charging: Up to 48A
Key Benefits
Save Money:
Avoid costly electrical upgrades ($5,000-$10,000 for panel upgrades)
Avoid new circuit installation costs ($1,000-$5,000 per circuit)
No Extra Hardware:
Works with just your Emporia chargers
No Vue monitor required
Automatic Operation:
No apps to check
No schedules to set
No cables to swap
Future-Ready:
Add more EVs without rewiring
Grows with your family's needs
Works Offline:
In offline mode, chargers operate at a default 6A per charger, ensuring basic functionality
Advanced features like dynamic load sharing require internet connectivity
Load Sharing vs PowerSmart
Load Sharing:
Prevents overload when multiple chargers share the electrical capacity
Manages power at the circuit or sub-panel level
No Vue monitor required
PowerSmart:
Prevents the main electrical panel from overloading due to total home energy use
Manages power at the main panel level
Requires a Vue energy monitor
Better Together:
Both features can work simultaneously for complete energy management. Load Sharing handles distribution between chargers, while PowerSmart manages overall household consumption to prevent panel overload.
Installation Scenarios
Shared Circuit:
Multiple chargers wired to the same breaker
Simplest setup
Most cost-effective installation
Dedicated EV Sub-Panel:
Each charger is on a separate breaker within an EV-only sub-panel
Maximum flexibility for individual circuit sizing
Easier to add chargers in the future
With PowerSmart:
Combined solution handles both circuit limits and total panel capacity
Ideal for homes with limited electrical service and multiple EVs
Who Benefits Most
Load Sharing is ideal for:
Multi-EV Households - Charge multiple vehicles without expensive electrical upgrades
Workplaces - Offer employee EV charging benefits cost-effectively
Apartment Complexes - Add EV amenities without massive infrastructure costs
Anyone - Needing multiple chargers with limited electrical capacity
Cost
Load Sharing is completely free - included with all Emporia EV chargers connected to the internet.
No hidden costs:
No subscription fees
No upgrade charges
No additional hardware purchases required
