  • Patent number: 11878604
    Abstract: A propulsion system for an electric vehicle comprising a high voltage battery unit having a first high voltage battery connected in series with a second high voltage battery, which may also be referred to as a first and second battery bank, and one or more power inverters arranged to connect the battery banks to one or more electric machines. The one or more power inverters and the one or more electric machines are configured to form a first and a second three-phase system. The described architecture incorporating dual battery banks, and dual and/or multiphase inverters and electric machines can provide enhanced redundancy and limp home functionality in cases where a fault or error occurs in the inverter and/or in the electric machine so that a faulty three-phase system can be operated in a safe-state mode.

  • Patent number: 11874331
    Abstract: One or more systems, devices, and/or system-implemented methods are provided that can facilitate provision of varying AC output voltage or DC output voltage, including selectively separately providing a positive voltage output, a negative voltage output and no voltage output. A device can comprise a battery cell, and a controller connected to the battery cell and that varies output from the battery cell, wherein the controller is configured to cause the battery cell to selectively separately provide negative output voltage, positive output voltage and no output voltage. A method can comprise varying output polarity from a multi-cell battery cluster and selectively providing one or both of alternating current (AC) voltage output or direct current (DC) voltage output from the multi-cell battery cluster due to the varying of the output polarity.

  • Patent number: 11866013
    Abstract: The present disclosure redirects unused condensed liquid water from the HVAC system to the washer fluid system such that the washer fluid tank, which may be relatively small and light, does not have to be topped-off frequently. The washer fluid tank is constantly refilled, and the washer fluid supply does not have to be replenished with clean drinking water as often, preserving this important environmental resource. Vehicle sensor data and/or a mobile application usage algorithm control filling of the washer fluid tank, and optionally periodically add anti-freeze from an adjacent reservoir when necessary to maintain an operable washer fluid system even below 0 degrees C.

  • Patent number: 11868108
    Abstract: One or more systems, devices, apparatus, computer-implemented methods, and/or system-implemented methods are provided that can facilitate artificial weathering of an object. In one example, an artificial weathering system can comprise a radiation generator configured to apply a constant radiation level to one or more surfaces of an object, and a controller configured to individually control a surface temperature at the one or more surfaces during the irradiation. The controller can be configured to maintain an ambient temperature range, that would be observed in a non-artificial environment, of a chamber containing the object during the irradiation. In another example, an artificial weathering system can comprise a controller configured to control an effect of radiation received at one or more surfaces of an object by controlling airflow directed towards the one or more surfaces, where the airflow is controlled based upon a surface temperature at the one or more surfaces.
