Abstract
An improved contactor device includes a high voltage switching device, current sensing components, and battery management components that may include a disconnect device. The contactor device may integrate, e.g., into a single device, a number of functionalities conventionally distributed across a number of disparate components and/or facilitate additional functionalities.
Claims20
A contactor device configured for electrical attachment to a high voltage system, the contactor device comprising:
- a housing;
- a switching device comprising a first fixed contact, a second fixed contact, and at least one movable contact, the movable contact being movable relative to the first fixed contact and the second fixed contact between a closed position that electrically connects the first fixed contact and the second fixed contact and an open position that electrically separates the first fixed contact from the second fixed contact;
- a coil disposed within the housing and configured to move the movable contact between the closed position and the open position;
- and
- current sensing components disposed within the housing and configured to measure a current supplied to or passed from the switching device.

An electrical system comprising:
- one or more batteries;
- and
- a contactor device coupled to the one or more batteries, the contactor device comprising:
- a housing;
- a switching device disposed within the housing, the switching device comprising a first fixed contact, a second fixed contact, and at least one movable contact, the movable contact being movable relative to the first fixed contact and the second fixed contact between a closed position that electrically connects the first fixed contact and the second fixed contact and an open position that electrically separates the first fixed contact from the second fixed contact;
- a switching coil disposed within the housing and configured to move the movable contact between the closed position and the open position;
- current sensing components disposed within the housing and configured to measure a current supplied to or passed from the switching device;
- and
- a fuse disposed within the housing and configured to prevent current flow through the contactor device in response to an event.
