Introduction to AgeVolt EMS
Article contents
AgeVolt EMS shares the available power between chargers according to the current energy needs of the building and vehicles. It allows vehicles to charge while parked using the existing main supply and configured limits.
What makes up the control system
| Component | Role |
|---|---|
| SmartSystem | The site's controller. It obtains data and sets the available charging power. |
| Metering | SmartMeter, a suitable Shelly device or compatible existing building metering supplies data on current consumption. |
| Charging stations | Provide charging data and accept power limits within their supported capabilities. |
| MyAgeVolt | A digital platform for management, reporting and other services according to the selected scope. |
Metering only where you need it
On a circuit supplying only chargers, the system can monitor the current limit using their own measurements. A separate SmartMeter is unnecessary for this purpose. If chargers share a supply with other appliances, control also needs data on the total consumption at that point.
From the main supply to individual circuits
Control considers the main supply, sub-distribution boards and charger circuits. At a metered point, a limit can be set in amperes, kilowatts or both. A circuit controlled using charger data uses a current limit in amperes. The result depends on correct station assignments and available measurements. EMS does not replace electrical circuit protection.
Priorities, solar power and the building
- Priorities determine which charging is limited sooner and which later when power is insufficient.
- Solar surplus mode uses energy that would otherwise be exported to the grid.
- SmartSystem can obtain data and receive limits from a compatible building system through Modbus RTU or TCP. The particular commands and available data are configured during integration.
How to select equipment
Start with the main supply rating, limiting points in the distribution circuits, existing metering and how long vehicles are parked. The basic SmartSystem CIB bus has capacity for 32 hardware elements, rather than 32 complete stations. A Smart Extender is used when expanding it.
