Introduction to AgeVolt EMS

AgeVolt EMS manages the power available for EV charging. It continuously shares capacity between vehicles according to building demand, electrical distribution limits and your operating rules. Charge while you park — at home, at work or in a public car park.

What makes up the system

A meter or building system supplies consumption data. Cloud EMS evaluates it and sends permitted limits to compatible charging stations. A vehicle draws only as much as the station and its own capabilities allow. SmartSystem can provide local metering and building integration; a supported Shelly meter connected directly to the cloud does not need SmartSystem as a gateway.

Metering where it is needed

On a supply shared by the building, equipment and vehicles, EMS needs total consumption. It can come from a meter, a sum of non-overlapping measurements or a building management system (BMS). A circuit serving only controlled chargers can use a shared charging budget without a separate meter. A BMS can also send a budget already calculated specifically for EV charging.

From the main supply to individual circuits

Spare capacity at the main supply does not mean the cable to a garage can carry it. Shared and downstream limits therefore apply together. Each vehicle respects every control point along its supply path. Current limits in amperes apply to each physical phase; kilowatts describe total active power. Both limits can apply at the same point.

Priorities, solar and the building

• At home, charging adapts to household appliances and can use solar surplus.
• A business can give fleet vehicles precedence and share capacity with staff or visitors.
• A car park can serve more spaces even when every vehicle cannot charge at full power at once.
• A BMS can change the budget to meet building needs. Time and price rules determine when to use grid energy.

Choosing a configuration

Start with supply and circuit limits, existing chargers, metering and how long vehicles park. In a model example, a shared supply limited to 60 kW with 35 kW of other demand leaves 25 kW for charging. If other demand rises to 50 kW, approximately 10 kW remains. Phase current limits may restrict charging further.

Cloud control needs a working internet connection. The configuration and its response are checked during commissioning. EMS supplements electrical protection; examples do not guarantee a particular power level or charge by departure.
