摘要： The invention relates to a method (100) of controlling a vehicle electrical system by an adjusted state-of-charge (SOC) window of a battery pack assembly in a vehicle. The method comprises the steps of receiving (110) a signal from a battery management unit comprising data indicative of the SOC of the battery pack assembly; determining (120) an energy throughput or a current throughput of the battery pack assembly; determining (130) a SOC window margin based on said determined energy throughput or current throughput of the battery pack assembly; adjusting (140) the SOC window in response to the determined SOC window margin; and controlling (150) the vehicle electrical system so that the SOC of the battery pack assembly remains within the adjusted SOC window.

摘要： The invention relates to a method for controlling the operation of an energy storage system (10) in a vehicle (30), preferably an electric or hybrid electric vehicle, said energy storage system (10) comprising at least two battery packs (12) connected in parallel, said energy storage system (10) being adapted to provide at least a nominal power functionality for propulsion of said vehicle (30) using an allowed operating extent of all of said battery packs (12) of said energy storage system (10), said allowed operating extent being a nominal working range of said battery packs (12); said method comprising disconnecting at least one battery pack (12); and setting said allowed operating extent for said remaining connected and active battery pack(s) (12) to an increased working range so as to enable said energy storage system (10) to provide said nominal power functionality to said vehicle (30), the method further comprising monitoring at least one accumulated parameter indicative of the operation of said energy storage system (10) from the time of disconnection of said at least one battery pack (12), and when said accumulated parameter reaches a threshold value, setting said allowed operating extent for said remaining battery pack(s) (12) to a decreased working range. The invention also relates to a control unit for controlling the operation of an energy storage system (10).
摘要翻译：本发明涉及一种用于控制车辆（30）中的能量存储系统（10）的操作的方法，该车辆优选为电动或混合动力电动车辆，所述能量存储系统（10）包括在至少两个并联连接的电池组（12），所述能量存储系统（10）适于使用所有所述电池组（12）的允许工作范围提供用于推进所述车辆（30）的至少标称功率功能，所述能量存储系统（10）的所述允许操作范围是所述电池组（12）的标称工作范围; 所述方法包括断开至少一个电池组（12）; 并且将所述剩余的连接的和活动的电池组（12）的所述允许的工作范围设置为增加的工作范围，以使所述能量存储系统（10）能够向所述车辆（30）提供所述标称功率功能，所述方法进一步包括从所述至少一个电池组（12）断开连接时监测指示所述能量存储系统（10）的操作的至少一个累积参数，并且当所述累积参数达到阈值时，设置所述允许将所述剩余电池组（12）的运行范围降低到减小的工作范围。本发明还涉及用于控制能量存储系统（10）的操作的控制单元。
