Abstract: A power system includes a battery and a controller. The controller inhibits charge of the battery according to voltage or current values sensed before and after contactors electrically connected to the battery are commanded to open and indicating that a leakage resistance associated with one of the contactors increases after the one of contactors is commanded to open, and a duration of a continuous voltage drop across another of the contactors after the another of the contactors is commanded to open exceeds a threshold.

Abstract: Electrified vehicle including a vehicle battery, and a processor configured to receive map data and generate a route based on the map data, and in response to a required vehicle energy needed to complete the route exceeding the current vehicle energy, modify the route to include at least one charging stop, wherein the at least one charge stop includes: a first number of shorter charging stops for recharging the battery at a first rate to a first state of charge less than a maximum state of charge, and a second number of longer charging stops for recharging the battery at a second rate to a second state of charge higher than the first state of charge, wherein the first rate is faster than the second rate and the first and second number of charging stops are selected to minimize combined charging time of the at least one charging stop.
