Control method for RESS fan operation in a vehicle

摘要

A method of controlling the ventilation system for an energy source in a fuel cell vehicle is disclosed, which includes an HVAC system, a fluid reserve, and a rechargeable energy storage system (RESS), capable of controlling a temperature of the RESS to militate against damage to or a shortened life of the battery, while maximizing vehicle durability, efficiency, performance, and passenger comfort.

主权项

1. A method for controlling the ventilation of a rechargeable energy storage system (RESS) in a vehicle, the method comprising the steps of:
(a) providing a ventilation system having an HVAC system in fluid communication with a fluid reserve, and the fluid reserve in fluid communication with the RESS; (b) determining the maximum noise output level of at least one vehicle component; (c) determining the ventilation requirement of the RESS; (d) controlling the flow rate of a fluid through a fluid transfer device for conveying the fluid from the reserve to the RESS as a function of the maximum noise output level and the ventilation requirement of the RESS; (e) determining a flow rate of the fluid through the fluid transfer device; (e) determining a flow rate requirement of the HVAC system; and (f) regulating a flow rate of the HVAC system such that the flow rate of the HVAC is equal to or greater than the flow rate of the fluid through the fluid transfer device.
