This disclosure relates to a battery charging system configured to selectively charge a battery pack of an electrified vehicle. More particularly, the battery charging system is configured to interrupt a buildup of carbon deposits. A corresponding method is also disclosed. In some aspects, the techniques described herein relate to interrupting a buildup of carbon deposits on a printed circuit board of a battery charging system configured to selectively charge a battery pack of an electrified vehicle, wherein the buildup of carbon deposits follows a path between an input pin of a relay on the printed circuit board and an output pin of the relay, and wherein the buildup of carbon deposits are interrupted by a slot formed in the printed circuit board.

Battery charging system configured to interrupt buildup of carbon deposits and corresponding method

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.

Cell specific traction battery monitoring

A battery pack according to an exemplary aspect of the present disclosure includes, among other things, a battery monitoring integrated circuit (BMIC) associated with a grouping of battery cells, a calibration microcontroller configured to store battery data associated with the grouping of battery cells, a main microcontroller; and a data transmission node establishing a shared path for communicating both a status signal from the BMIC and the battery data from the calibration microcontroller.
