  • Publication number: 20230387672
    Abstract: A thermally conductive bracket is contemplated for use in a vehicle to facilitate transfer heat from a busbar to a cold plate, such as to assist with heat transfer to a cold plate used to act as a heat sink for a plurality of battery cells connected to the busbar. The bracket may include a thermally conductive heat transfer material shaped to receive the busbar where at least a portion of the material is configured to include opposed sides and a bottom such that the opposed sides are configured to transfer heat from the busbar to the bottom and the bottom is configured to transfer heat from the sides to the cold plate.

  • Patent number: 10886758
    Abstract: An electrical system includes a battery disconnect unit (BDU) connected to a rechargeable energy storage system (RESS) via a high-voltage bus. The BDU has one or more contactors that close responsive a low-voltage drive current to thereby connect the RESS to the high-voltage bus. A low-voltage drive circuit conducts the drive current to the contactor(s). Opening of a low-voltage connection interrupts the drive current and causes the contactor(s) to transition from the closed state to an open state. The contactor(s) open in response to interruption of the drive current to thereby disconnect the RESS. The contactor(s) may be closed again after a lockout safety procedure, such that reestablishing the electrical connection does not itself re-energize the high-voltage bus. An electrified powertrain includes a transmission, electric machine, power inverter module, and the above-noted electrical system.

  • Patent number: 9997878
    Abstract: According to aspects of the present disclosure, a lightweight busbar includes an aluminum body, a copper connector, and a cladded interface. The aluminum body defines a first end and a second end opposite the first end. The copper connector is disposed proximate the first end of the aluminum body. The copper connector is configured to be fastened to an external component. The cladded interface bonds the copper connector to the first end of the aluminum body. The cladded interface inhibits yield between aluminum and copper during thermal cycling.

  • Publication number: 20150330800
    Abstract: Systems and methods for personalized multi-destination trip planning are provided. One example system includes one or more processors and one or more non-transitory computer readable media storing instructions that cause the one or more processors to perform operations. The operations include receiving a routing request associated with a user. The routing request includes a list identifying a plurality of desired destinations. At least one of the plurality of desired destinations is a generalized location identifier. The operations include determining a plurality of specific destinations that satisfy the generalized location identifier. The operations include selecting, from the plurality of specific destinations, a recommended one of the specific destinations based at least in part on one or more attributes associated with the user. The operations include providing a personalized recommended route for display to the user.

  • Patent number: 8936394
    Abstract: Methods and systems for estimating the core temperature of at least one cell in a battery at the termination of a rest period. The method for estimating the core temperature of the cells in a battery includes measuring the surface temperature of the cells, obtaining the estimated core temperature of the cells, obtaining the time required for the surface temperature and the estimated core temperature of the cells to converge, and estimating the core temperature of the cells based on the measured surface temperatures, the obtained estimated core temperature, and the obtained time. The system for estimating the core temperature of the cells in a battery includes at least one sensor configured to receive temperature information and a control system in signal communication with the sensor, wherein the control system comprises a memory device and a controller.

  • Patent number: 8529125
    Abstract: Methods and systems for dynamically estimating the core temperature of at least one cell in a battery during an operative period. The method includes receiving by at least one controller the surface temperature, the current, the voltage, the state of charge, and the period of time from the initiation of a rest period to the termination of the rest period, determining an initial value of the lumped internal resistance of the at least one cell, determining subsequent values of the lumped internal resistance recursively in real-time based on the initial value, the current, and the voltage, and determining the core temperature of the at least one cell based on the surface temperature, the current, the obtained time, and the lumped internal resistance.
