摘要： A battery system has a battery cell including a can, and a ceramic substrate, including a patterned metallized surface, mounted to the can via a thermally conductive adhesive. The battery system also has a monolithic integrated circuit that measures and transmits data about the cell mounted to the patterned metallized surface such that the ceramic substrate and monolithic integrated circuit are electrically isolated from one another.

摘要： A header connector includes a body, a staggered column of L-shaped connector pins of two different lengths extending in a same direction from a first side of the body, and a staggered column of mating pins on a second side of the body opposite the first side. Each one of the mating pins is connected with one of the connector pins.

摘要： A traction battery assembly includes, among other things, a cover of a battery array, a holder attached to the cover, and a circuit board held by the holder in a position where the circuit board is spaced from the cover. The holder is configured to communicate thermal energy between the circuit board and the cover. A method of securing a circuit board of a traction battery pack includes, among other things, holding a circuit board with a holder, and attaching a holder that is holding the circuit board to a cover of a battery array. The circuit board held by the holder is held in a position where the circuit board is spaced from the cover.

摘要： A traction battery arrangement includes a string of cells and bus bars, a coil wrapped around one of the bus bars, and a controller. The controller drives AC current over a swept range of frequencies into the one of the bus bars via the coil, and receives voltage data from at least one of the cells that results from the AC current.

摘要： A vehicle includes a traction battery, circuitry including a switch and a capacitor, and a monitoring chip configured to draw power from a cell of the traction battery via the circuitry responsive to the switch being closed. The circuitry is configured to open the switch to disconnect the cell from the chip and power the chip via the capacitor for a predetermined period. Powering the chip via the capacitor prevents power down of the chip during the predetermined period. The circuitry opens the switch responsive to engine cranking.

摘要： A high-voltage system for a vehicle includes a module having a resonant circuit coupled across powerlines, and a controller. The controller is programmed to, during a power up of the high-voltage system, propagate on the powerlines a first signal at a fundamental frequency for a first period. The controller is further programmed to, in response to a first impedance measured across the powerlines at the fundamental frequency during the period being less than a predetermined value, close main contactors to energize the module.

摘要： A hybrid vehicle battery system that comprises a plurality of cells that are electrically coupled to an electric motor of the vehicle is provided, the electric motor being mechanically coupled to a drive system of the vehicle. The battery system is configured to: determine a voltage requirement of the battery system at least partially based on a current operating mode or an anticipated operating mode; and adjust the configuration of the cells in order to increase or decrease the voltage of the battery system according to the requirement. A method of operating a hybrid vehicle is also provided.
