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 ().

A method of managing leakage of liquid inside a battery system comprises: containing leaking liquid in a non-liquid sensitive region of the battery system so as to protect internal electrical components of the battery system from coming in contact with the leaking liquid; and in direct response to the leakage, expunging the leaking liquid from the battery system. A drain device includes: a body with a port therethrough, the body configured to be positioned in a wall of a container; means for opening the port in response to a first liquid contacting the drain device on an inside of the container; and means for resisting ingress into the container by a second liquid that contacts the drain device on an outside of the container.

Self-activated draining system

An electromagnetic switch includes: a stationary electrical contact; a moveable electrical contact; an actuated member to which the moveable electrical contact is attached for driving the moveable electrical contact into and out of contact with the stationary electrical contact; and a damping interface between the moveable electrical contact and the actuated member.

A system and method for providing energy management and maintenance of a high energy battery pack that does not require installation of the battery pack into an operational EV. A secondary service port is provided to enable certain maintenance operations while by-passing battery pack interlocks and protection mechanisms used when the battery pack is installed into an operating environment.
