  • Publication number: 20180219266
    Abstract: A battery pack has an enclosure that contains a plurality of batteries and conductors and that resists the flow of fluid between an interior of the enclosure and an exterior of the enclosure. An exit vent formed in the enclosure at a first location allows exhaust gas to flow from the interior of the enclosure to the exterior of the enclosure. A fill port formed in the enclosure at a second location, in an impermeable state, prevent ingress of fluid from an exterior of the enclosure to an interior of the disclosure. The fill port, in a permeable state achieved by receipt of a perforation tool there through, permits ingress of a sufficient amount of a thermal-control liquid into the enclosure through the fill port to terminate a runaway thermal event in the battery pack. A fill port coupler having a passageway and an externally accessible port may be included.

In a differing embodiment, a rotor discharge brush coupled between the case and the rotor shaft along the longitudinal axis of the rotor shaft discharges the common mode charge.

    Abstract: An electric motor includes a case, a stator that includes end-windings, a rotor coupled to the case via at least one rotor bearing, at least one drive motor fluid pump, and drive motor electronics. The rotor includes a hollow cylindrical body, a first shaft portion, and a second shaft portion, a fluid feed tube having a fluid receive end and a fluid feed end, the fluid feed end extending into the hollow cylindrical body, and a plurality of fluid exit ports. The drive motor electronics power the stator with or without causing rotation of the rotor. The drive motor fluid pump pumps fluid into the hollow cylindrical body via the fluid feed tube, pumps the fluid out of the plurality of fluid ports, and onto the stator end-windings to collect heat from the rotor and the stator. The heated fluid may be used for heating a battery.

  • Patent number: 9899652
    Abstract: 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.

  • Publication number: 20180045423
    Abstract: A combined gas-compressor and dehumidifier system composed of a gas compressor for compressing a first gas, a dehumidifier for dehumidifying a second gas, and a cooling system. The gas compressor is composed of (a) one or more compression stages and (b) one or more intercoolers, wherein the one or more intercoolers are connected to a cooling system. The dehumidifier for dehumidifying a second gas is composed of a first dehumidifying stage that uses a first desiccant to adsorb water from the second gas and output a second intermediate gas, a second dehumidifying stage that uses a second desiccant to adsorb water from the second intermediate gas, and a waste heat exchanger, wherein the waste heat exchanger is used to reactivate the first desiccant. The cooling system is composed of a liquid contained in connectors, and the connectors connecting the one or more intercoolers to remove heat from the gas compressor and provide the removed heat to the dehumidifier.
