Connected fuel cell vehicle predictive freeze wake scheduling
Methods and systems for operating fuel-cell systems are disclosed. The amount of time the fuel-cell system is to be shut down can be calculated using external weather-related information. The amount of time the fuel-cell system is to be shut down can also be calculated using default settings. The fuel-cell system may be used to power an electric vehicle.
1 . A vehicle comprising:
a fuel cell system; and
one or more processors programmed to, while the vehicle is parked, perform a wake operation for the fuel cell system at a time defined by a schedule such that the time is based on obtained weather forecast data for a location of the vehicle responsive to a confidence associated with the weather forecast data exceeding a threshold and is based on a default setting responsive to the confidence not exceeding the threshold.
2 . The vehicle of claim 1 , wherein the one or more processors are further programmed to, after receiving a signal to shut down the fuel cell system, generate the schedule.
3 . The vehicle of claim 1 , wherein the one or more processors are further programmed to, after performing the wake operation, update the schedule.
4 . The vehicle of claim 3 , wherein the one or more processors are further programmed to obtain additional weather forecast data after performing the wake operation.
5 . The vehicle of claim 1 , wherein the one or more processors are further programmed to inhibit performing the wake operation responsive to presence of a predefined condition.
6 . The vehicle of claim 5 , wherein the predefined condition is ambient temperature exceeding a predefined value.
7 . The vehicle of claim 1 , wherein the one or more processors are further programmed to receive off-board commands to perform the wake operation.
8 . A fuel cell system for a vehicle comprising:
a fuel cell stack; and
one or more processors programmed to, while the vehicle is parked,
perform a wake operation for the fuel cell stack responsive to receiving an off-board command to perform the wake operation, and
perform the wake operation at a time defined by a schedule such that the time is based on a default setting responsive to off-board communication being unavailable.
9 . The fuel cell system of claim 8 , wherein the one or more processors are further programmed to, after receiving a signal to shut down the fuel cell system, generate the schedule.
10 . The fuel cell system of claim 8 , wherein the one or more processors are further programmed to, after performing the wake operation, update the schedule.
11 . The fuel cell system of claim 8 , wherein the one or more processors are further programmed to inhibit performing the wake operation responsive to presence of a predefined condition.
12 . The fuel cell system of claim 11 , wherein the predefined condition is ambient temperature exceeding a predefined value.
