Systems and methods for controlling cabin heating in fuel cell vehicles

摘要

System and methods for controlling and optimizing coolant system parameters in a fuel cell system to obtain a requested cabin temperature in a fuel cell vehicle are presented. A method for managing a temperature in a vehicle cabin may include receiving an indication relating to a desired vehicle cabin temperature and a plurality of measured operating parameters. Based on the measured operating parameters, a projected output temperature of a cabin heat exchanger may be estimated. A determination may be made that the projected output temperature of the cabin heat exchanger is less than the indication. Based on the determination a fuel cell coolant parameter may be adjusted.

1. A method for managing a temperature in a vehicle cabin while reducing impacts on fuel cell system durability and efficiency, the method comprising:
receiving an indication relating to a desired vehicle cabin temperature; receiving a plurality of measured operating parameters; estimating, based on the measured operating parameters, a projected output temperature of a cabin heat exchanger; determining that the projected output temperature of the cabin heat exchanger is less than the indication; and adjusting, based on the determination, a fuel cell coolant parameter.
