Intelligent load management
Dynamically distributes charging electricity and prevents overloading the property's electrical network.
The basic idea of load management is to protect the property's metering point or points from overload.
The system's base load management is not always sufficient. Good examples of this are sites where the load changes suddenly or where it is impossible to estimate the site's free capacity.
CAMU (Compact Ampere Measuring Unit) measures the actual current of the fuses. It can be used to measure the load of the desired measurement points and dynamically adjust the remaining capacity of the electric vehicle charging devices. The measurement data is transmitted wirelessly to the eParking Gateway connection device and the eParking cloud service, where the actual load management takes place.
Load management levels
| Feature | Level 0 | Level 1 | Level 2 |
|---|---|---|---|
| Current values | Fixed, static | Fixed, static | Changing, dynamic |
| Power limitation | Plug-specific limit | Group-specific, only for eTolppaloads | Group-specific, also for non eTolppaloads |
| Limit values | Configurable | Configurable | Configurable |
| Implementation locations | Device-specific | Multiple levels: main center, sub-center, groups, phases | Multiple levels: main center, sub-center, groups, phases |
| Non- eTolppacargo | Can be cut off or limited | Low load can be excluded (factor 1) | Requires a separate measurement point |
Level 0 (Device specific)
Sets a fixed, static current limit for a device or plug using software during manufacturing or commissioning. Suitable for applications where electrical capacity does not need to be dynamically shared with other devices.
Level 1 (Group-specific)
A fixed maximum power is reserved for the charging system from the power center, which is divided equally or according to priorities among all chargers. An intelligent algorithm ensures that the charging stations do not overload the group fuse.
Level 2 (Dynamic)
Tracks the property's other constantly changing electricity consumption in real time and requires a separate measurement point (e.g. CAMU). Charging stations are provided with the capacity that is currently free in the property.
