摘要： The invention relates to a method for thermal conditioning of a battery pack (4), wherein said battery pack (1) comprises a plurality of battery cells (4a, 4b, 4c, . . . ) and forms part of an electric storage system (15), said method comprising a step of executing a ready-to-run function for optimizing the performance of said battery pack (4) during use. Furthermore, the method comprises the steps of: calculating a setpoint temperature (Ts) for the battery pack (4) to reach in order to provide a sufficient level of performance without further thermal conditioning during a predetermined time period (t); and thermally conditioning said battery pack (4) so as to reach said setpoint temperature (Ts). The invention also relates to an arrangement for such a thermal conditioning.

摘要： A system and method for controlling operation of a fuel cell system of a fuel cell vehicle, to reduce an amount of heat generated by one or more heat sources in the fuel cell system, are provided. The method comprises obtaining a value of power output of the fuel cell system, the value indicating a power demand from the fuel cell system during operation of the vehicle; and adjusting a value of a target coolant inlet temperature of a coolant at a coolant inlet of the fuel cell stack to vary between a first target temperature level and a second target temperature level, in dependence on the value of the power output, to optimize a duration of time during which the target temperature is different from the first target temperature level and to optimize a value of one or more parameters related to operation of the fuel cell system.
