摘要： A method controlling a battery management system is provided. The method may include commanding by a controller a heat exchanger of a vehicle to pre-cool a traction battery of the vehicle key-off responsive to the vehicle being within a predetermined range of a predicted parking location, a current temperature of the traction battery being less than a temperature threshold, and a predicted parked temperature for the traction battery being greater than the temperature threshold.

摘要： A battery thermal management system includes an inner housing containing a plurality of battery cells, and an outer housing enclosing the inner housing. A fluid channel is defined between an exterior surface of the inner housing and an interior surface of outer housing. The thermal management system also includes a fluid circulator in fluid flow communication with the fluid channel to selectively circulate one of a first thermal fluid and a second thermal fluid through the fluid channel.

摘要： A vehicle charging system includes a vehicle propelled by an electric machine powered by a chargeable energy storage system. The charging system also includes a controller programmed to predict at least one upcoming plug-in event based on historical charging data, and define a plug-in routine based on a plurality of upcoming plug-in events. The controller is also programmed to set a charging schedule to coincide with the plug-in routine such that a target state of charge (SOC) is achieved at a conclusion of each of the plurality of upcoming plug-in events. Each target SOC corresponding to a plug-in event is based on minimizing a charging energy cost of the plug-in routine and an expected energy depletion ahead of a next subsequent plug-in event.

摘要： A capacitor is configured to be in thermal contact with an electrical load. A controller is configured to charge and discharge the capacitor to change a temperature of the capacitor. The controller is configured to selectively discharge the capacitor at a discharge current at which entropic cooling of the capacitor is greater than Joule heating of the capacitor to provide cooling for the electrical load.

摘要： A vehicle can include a traction battery and a controller in communication with the battery to determine the battery state using sensed battery electrode capacity to account for battery aging. The sensed battery electrode capacity can be dependent on active lithium ions at a positive electrode of the traction battery. The controller can compare a battery voltage model to measured battery voltage during a vehicle drive cycle, receive sensed current though put data and open circuit voltage at the battery, and determine if a deviation threshold is exceeded. The controller can also correct electrode capacity using a mean of the measured open-circuit voltage to correct the capacity error to less than one amp-hour or initiate an active lithium capacity correction using a variance of the current throughput to correct the capacity error to less than one amp-hour. This information can be used to control the vehicle and battery usage.
