A vehicle power system includes at least one main switch to electrically connect a traction battery and electric machine, at least one DC charge switch to electrically connect the traction battery and a DC charge port when the at least one main switch is closed, and a controller to, while the DC charge port is disconnected from a DC power source, sequentially close the at least one DC charge switch and then the at least one main switch.

Isolation fault detection on DC charge bus

A method of detecting a thermal event associated with a battery assembly of an electrified vehicle includes, among other things, obtaining a temperature reading from a sensor associated with an area of the battery assembly, assessing whether the sensor is flagged with a first identifier or a second identifier. The first identifier indicates that the temperature reading is reliable. The second identifier indicates that the temperature reading is unreliable. If the sensor is flagged with the first identifier, the method detects a thermal event associated with the battery assembly based on the temperature reading from the sensor.

Traction battery pack thermal event detection

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.
