Load Sharing is Emporia’s intelligent power management solution that allows multiple EV chargers to coordinate power delivery without exceeding electrical limits. For chargers installed in 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 in a dedicated EV sub-panel to automatically share available power.
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 sub-panel’s capacity.
Compatible Chargers
Load Sharing works with:
Emporia Pro EV Charger
Emporia Classic EV Charger
No additional hardware or Vue monitor required.
Homes requirement: all chargers in a Load Sharing network must be in the same Home, or all Unassigned. The app will not let you move a charger to a different Home if the move would split the network. To move it, first disable or delete the Load Sharing network, or move all of its chargers to the same Home together. See Understanding Homes in the Emporia App.
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 EV Sub-Panel
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)
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 chargers to your network as your household grows
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 and PowerSmart both help prevent overloads when you add EV charging, but they protect different parts of your electrical system. Whether you need either depends on how much capacity your panels have available. Your electrician can help you determine this.
Load Sharing:
Divides a set amount of power between two or more Emporia EV chargers that share the electrical capacity
Helpful when a sub-panel dedicated to Emporia EV Chargers is at risk of overloading with all chargers running
Manages power at the EV sub-panel level
Works with both the Emporia Pro and Classic EV Chargers
No Vue monitor required
Prevents a panel from overloading due to total energy use, including loads other than your EV charger(s)
Manages power at the panel level
Requires a Vue energy monitor
Included with the Emporia Pro EV Charger. The Classic EV Charger can add PowerSmart with a $125 software upgrade; contact our Customer Support team
Neither:
If your panel has enough unallocated amperage for the circuit(s) you’re adding, you may not need either feature.
Using Both Together:
Load Sharing and PowerSmart can also work together when your setup calls for it. Load Sharing handles power distribution between your chargers, while PowerSmart manages overall household consumption to prevent panel overload. For example, if both your main panel and the dedicated EV sub-panel feeding your chargers are at risk of overloading, PowerSmart can protect the main panel while Load Sharing manages the sub-panel. Your electrician can help determine whether your setup calls for one feature, the other, or both. If you use both, PowerSmart must be enabled on every charger in the Load Sharing network.
