A system for powering an electric vehicle (EV) includes a battery, a power distribution module, and a battery bypass module. The power distribution module receives power from a charging station, draws power from the battery in a discharging mode, distributes power from the charging station to the battery in a charging mode, and distributes power to a plurality of subsystems of the EV. The battery bypass module is coupled to the battery and the power distribution module. When the battery bypass module is engaged in a charging bypass mode, power distributed by the power distribution module bypasses the battery and is distributed to at least a subset of the plurality of subsystems of the EV.

A method for controlling an exchange of power between a charging infrastructure and an electricity supply grid is provided. A number of power units are formed as electric vehicle. Each power unit has a variable state of charge. From the individual states of charge of the power units, an overall state of charge can be determined. For the overall state of charge, a flexibility range in dependence on time can be predefined for a control time period. The flexibility range is spanned by a progression over time of an upper limit of the overall state of charge and a progression over time of a lower limit of the overall state of charge for the control time period. The flexibility range has range points which can be defined by a value of the overall state of charge and a point in time in the control time period.

A method of controlling an electric marine propulsion system to propel a marine vessel includes receiving a user-set time, determining a time remaining based on the user-set time, and identifying a battery charge level of a power storage system on the marine vessel. A required battery power is then determined based on the time remaining and the battery charge level, and then an output limit is determined based on the required battery power to enable propelling the marine vessel for the user-set time without recharging the power storage system. The propulsion system is automatically controlled so as not to exceed the output limit.
