Embodiment Construction

[0026] figure 1 A prior art control circuit 30 is shown in FIG. The control circuit 30 for controlling the two contactors, of which only the control coil 50 is shown respectively, is connected via the first and second connection terminals 11 , 12 to a voltage source 60 which supplies the control circuit 30 , but also provides current controlled by the control circuit 30 for controlling the contactors. The control coils 50 of these contactors are connected to the control circuit 30 via the first output terminal 15 and the two second output terminals 16 . The control circuit 30 has a first switch 41 and two second switches 42, wherein the first switch 41 is connected between the first electrode of the voltage source 60 and the first output terminal 15 of the control circuit 30, and the two The second switch 42 is respectively connected between the second electrode of the voltage source 60 and the corresponding second output terminal 16 of the control circuit 30, so in the corr...

Abstract

The invention relates to a control circuit (30) for at least two contactors, which comprises at least one first outlet (15) and at least two second outlets (16) which enable said control circuit (30) to be connected to the connections of at least two control bobbins for at least two contactors. Said control circuit (30) also comprises a holding voltage unit (10) which is connected to the at least one first outlet (15) via the outlet (6) and is designed to provide on the outlet (6), a holding voltage for adjusting a holding current for the control bobbins. Said control circuit (30) further comprises a regulating circuit (20) which is connected to the electric connections (8) and to the inlet (9) of the holding voltage unit (10) and is designed to generate a control signal which is dependent on the currents circulating in the electric connections (8) and to transmit to the holding voltage unit (10). The invention relates to a method for operating at least two contractors.

Description

technical field [0001] The invention relates to a control circuit for at least two contactors, which has a regulating circuit by means of which the current through the control coils of these contactors is regulated. Background technique [0002] Obviously, more battery systems will be used in the future, not only in stationary applications, but also, for example, in hybrid and electric vehicles, for which very high demands are placed with regard to reliability. The reason is that the failure of the battery can lead to safety-related problems. In order to provide the power desired for the respective application, a large number of battery cells are usually connected in series, resulting in a high output voltage of the battery without suitable measures for permanent contact with the corresponding power supply of the equipment powered by the battery connections and represent a hazard to maintenance personnel or users. For this reason, contactors are usually provided in order t...
