Operating principle

The state of charge to be adjusted is passed on as follows depending on the configuration:

• As absolute voltage in [V] – Adjust the state of charge according to the specified absolute voltage.
• As percentage value (between 0% and 100%) – Adjust the state of charge depending on the operating range specified in the configuration.
• As absolute energy value in [Ws] – Adjust the state of charge according to a specified absolute amount of energy in the DC link.

Furthermore, a charge limit can be transferred as follows to limit the charging of the DC link or connected energy storage unit:

• As power limit – Limit the device current on the respective control side so that the specified power limit results with the current voltage.
• As current limit – Limit the maximum device current on the respective control side to the specified value.
