Abstract
An electric marine propulsion system configured to propel a marine vessel includes a power storage system comprising a plurality of batteries and at least one electric motor powered by the power storage system and configured to rotate a propulsor to propel the marine vessel. A control system is configured to identify a charge level for each of the plurality of batteries and determine which of the plurality of batteries are active batteries based at least in part on the charge level on each of the plurality of batteries. A minimum power limit is then identified for the active batteries and a system power limit is determined based on the minimum power limit and the number of active batteries. The at least one electric motor is then controlled based on the system power limit such that the system power limit is not exceeded.
