Abstract: Vehicles that use electric power as a motive force may use accurate measurements of battery power for numerous purposes, e.g., battery characteristics, state of charge of the battery, travel distance remaining for the vehicle and the like. A traction battery measurement should be taken when the battery is fully relaxed, i.e., the battery is neither being charged nor providing power and a time period thereafter when the battery chemistry reaches a steady state. A controller or methods may determine if the battery is relaxed and if the battery is not relaxed, delay charging or discharging of the traction battery to allow accurate battery capacity determination. The controller may control a battery charger to ensure the battery is fully relaxed before sensing battery characteristics.

Abstract: A battery management system for a vehicle includes a controller programmed to apply a current pulse to reverse a current flow through a battery to reduce or remove cell polarization. After the current pulse, an open-circuit voltage is measured as the terminal voltage of the battery. The settling time for the terminal voltage to approach the open-circuit voltage is reduced after the current pulse. The magnitude of the current pulse is based on a battery state of charge, a battery temperature, and a current magnitude prior to the current pulse.

Abstract: 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.
