  • the ripple current generator is usually connected to an HV bus, which connects the battery with a unit for charging and discharging the battery.
  • the regulation of the ripple current in known test systems depends, among other things, on a DC current on the HV bus.
  • certain impedance ratios of the HV bus and / or the battery can influence the current distribution and thus influence the ripple current actually reaching the battery.
  • the primary sensor has two sensor elements for, in particular contactless, current measurement on a respective connection line of the connection device.
  • both sensor elements can be designed in accordance with the sensor element described above.
  • Each of the sensor elements can preferably have a Rogowski coil or be designed as a Rogowski coil.
  • one of the sensor elements can be arranged on a connection line in the form of a positive line and one of the sensor elements can be arranged on a connection line in the form of a negative line.
  • the current sensor unit can have a higher resistance to common-mode interference.
  • the use of two sensor elements makes it possible to measure a common-mode current at the connection device. At the same time, this enables common-mode signals or common-mode signals to be coupled in, in particular by means of a common-mode module of the control unit.
  • the common-mode signals or common-mode signals can be regulated in a closed control loop.
  • the coupling device has a control unit with an operating module for regulating the, in particular coupled, ripple current as a function of the first current parameter. Furthermore, it is provided according to the invention that the connection unit has a coupling circuit for decoupling the rib current unit from an external connection voltage of the connection device, in particular on the connection means.
