The present invention relates to a contactor device (), which is capable of changing a connection state of at least two battery modules ((),()) of a high voltage energy storage system () between a series connection and a parallel connection, and to an energy storage system () comprising the contactor device (). The contactor device () comprises two first terminals () for electrically connecting at least one of a load and a charger, two second terminals () for electrically connecting a first battery module (()), and two third terminals () for electrically connecting a second battery module (()). The contactor device () further comprises two first bus bars (), which each are electrically connected to one of the first terminals (), and two second bus bars (), wherein one of the second bus bars () is electrically connected to one of the second terminals (), and the other one of the second bus bars () is electrically connected to one of the third terminals (), and a connection bus bar (), which is electrically isolated from the two first bus bars (). At least one actuation element is configured to change a state of the contactor device () at least to and from a series connection state, in which the two second bus bars () are conductively coupled to the connection bus bar (), and to and from a parallel connection state, in which one of the second bus bars () is conductively coupled to one of the first bus bars () and the other one of the second bus bars () is conductively coupled to the other one of the first bus bars ().

Contactor device and energy storage system

The present invention relates to a contactor device for high voltage applications, an energy storage system comprising the contactor device and a corresponding method for controlling the contactor device. A contactor device () comprises at least one fixed contact (), at least one moveable contact (), which is configured to move between an open position and a closed position, wherein in the closed position, the at least one moveable contact () electrically contacts the at least one fixed contact (), and at least one first actuator (), which is configured to reversibly move the at least one moveable contact between the open position and the closed position. The contactor device () further comprises at least one second actuator () which is configured to move the at least one fixed contact () into a fired position, wherein in the fired position, the at least one fixed contact () is permanently disconnected from the at least one moveable contact ().

Contactor device, energy storage system and method for controlling a contactor device

A resistor arrangement having a first electrically conductive connection element and a second electrically conductive connection element, a first resistance element which is electrically conductively connected to the first connection element, a second resistance element which is electrically conductively connected to the second connection element, an electrically conductive intermediate element arranged between the first resistance element and the second resistance element and connected with these resistance elements in an electrically conductive manner, wherein the connection elements, the resistance elements and the intermediate element are arranged side by side in a row. The connection elements and the intermediate element on the one hand and the resistance elements on the other hand formed of different materials, wherein the material of the first resistance element differs from the material of the second resistance element.
