摘要： A system is provided for vehicle range prediction. The system determines a change in mass to a vehicle while driving. Additionally, the system calculates a vehicle load in response to determining the change in mass and adjusts a vehicle range in response to calculating the vehicle load. The vehicle range is indicative of a distance in which the vehicle is predicted to travel with a remaining fuel. The adjusted vehicle range is based on the vehicle load.

摘要： A fuel cell electric vehicle (FCEV) power control system reduces a power limitation in conditions such as uphill driving and/or high temperature environments. The FCEV power control system utilizes dynamic cooling detection logic and/or predictive convection. The FCEV power control system may be operated in accordance with a method of controlling power of a fuel cell including receiving a plurality of inputs including a heat output of the fuel cell, an ambient temperature, a temperature of a coolant of the fuel cell, and a time of operation of the fuel cell. The method may include calculating an accumulation of cooling from convection, an accumulation of heat generated from the fuel cell, and a cooling ratio. The method may include adjusting a maximum allowable current of the fuel cell based on the cooling ratio. Related apparatuses, systems, techniques and articles are also described.

摘要： A method of controlling ignition of a vehicle having a fuel cell system is provided. In particular, the method includes a step of determining an idling state of the vehicle, a step of determining whether to enable a fuel cell on/off mode, a step of determining a degree of water balance of a fuel cell stack, and a step of turning off a vehicle's ignition switch. More specifically, a fuel cell system controller determines whether to enable a fuel-cell on/off mode based on a coolant temperature of the fuel cell system once the idling state is determined, and also determines a degree of water balance of a fuel cell stack of the fuel cell system. The fuel cell system controller turns off the vehicle's ignition switch, when a predetermined time passes, based on the degree of water balance.

摘要： Methods and systems are described for optimizing water discharge in fuel cell vehicles. The system includes a fuel cell stack, a blower for purging water from the fuel cell stack and a controller. The controller detects that an ambient temperature satisfies a threshold temperature. The controller determines the fuel cell vehicle is approaching a stopping location. The controller calculates a water discharge time prediction necessary to purge excess water from the fuel cell stack while the fuel cell vehicle is operating in response to detecting that the ambient temperature satisfies the threshold temperature and the fuel cell vehicle is approaching the stopping location. The water discharge time prediction is calculated based on the blower operating while the fuel cell stack is in at least one of an idle state and a stopped state as the fuel cell vehicle approaches the stopping location.

摘要： A coolant temperature control system for a fuel cell stack in a vehicle includes a controller for determining a real time target exit temperature of a fuel cell stack coolant and a communicating device for detecting a fuel cell voltage and a fuel cell current outputted from the fuel cell stack. The real time target exit temperature of the fuel cell stack coolant is determined by an input fuel cell heat to fuel cell power ratio generated from the fuel cell stack for compensating the target exit temperature due to degradation of the fuel cell stack over time. In addition, the coolant temperature control system determines to activate for evaluating the real time target exit temperature of the fuel cell stack coolant when a trip distance of the vehicle is greater than a predetermined travel distance.
