CONTROL SYSTEM AND METHOD FOR PREVENTING HYDROGEN BOIL-OFF LOSSES

Abstract: control system and method for controlling state of hydrogen charge in hydrogen storage system in a vehicle to prevent hydrogen boil-off losses. the control system obtains information about predetermined stop duration and location for vehicle; obtains information on required hydrogen usage for reaching predetermined stop location from a current location of the vehicle; obtains information on a maximum hydrogen level of the hydrogen storage system to prevent hydrogen boil-off losses when the vehicle reaches the predetermined stop location and the stop duration starts; and generates a control signal for controlling the state of hydrogen charge of the hydrogen storage system based on a current hydrogen level in the hydrogen storage system when the vehicle is at the current location, the required hydrogen usage for reaching the predetermined stop location and the maximum hydrogen level of the hydrogen storage system to prevent hydrogen boil-off losses.
