The Wallbox Manager block takes over the energy management of multiple Wallboxes.
It fulfills the following functions:
To prevent upstream fuses from tripping, all wallboxes and their electrical cabling structure can be replicated in the block. Both the total power and the power per fused strand can be limited.
Distributes the available power to all wallboxes, considering the predefined power limits. By default, vehicles charge in Eco mode, sharing only the available excess power. Only vehicles charging in Priority mode are assigned as much power as possible.
Definition of prices per kWh for charging in Eco and Priority modes, as well as a connection fee per hour. These prices are transferred to the linked Wallbox blocks.
Shows an overview of the energy distribution with status and power of the linked Wallbox blocks.
Table of Contents
|Maximum total power
|Maximum total power available to the Wallboxes.
Used primarily as maximum value for overload protection.
Can also be used to restrict charging power during periods of high electricity prices or high consumption.
|Power for Eco charging
|Excess Power, which is distributed to the Wallboxes for Eco charging.
|Pulse: Outputs are reset / switched off.
On: Block is locked.
The name of the connected sensor is used in the user interface.
|Current total power consumption of all Wallboxes.
For wallboxes whose power consumption is not known (no meter available or Cp input not used), the assigned power is assumed.
|Total power assigned to the wallboxes.
Sum of Tp of all linked wallboxes.
|Intelligent API based connector.
|Price per kWh for Eco charging.
|Price per kWh for Priority charging.
|Connection fee per hour
|Price per hour while the vehicle is connected.
|Number of entries in the control history.
0: History is disabled
Control history tracks relevant changes since program start.
|Configure the Wallbox Manager by adding Wallboxes and grouping them together.
First, existing Wallbox blocks are added in a tree structure and grouped into strands. A strand is a group of wallboxes that are protected by a common higher-level fuse. The power can be limited for the individual strings. Select a value that matches the fuse protection or load capacity of the string:
As soon as a Wallbox block has been added, only two fixed charging modes (Eco and Priority) are available. The energy distribution is controlled by the Wallbox Manager.
The maximum power and the excess power available for Eco charging must be specified at the inputs of the Wallbox Manager:
