The electric circuit includes at least one first switching unit, one second switching unit, and one third switching unit electrically connected to the poles of the electrical energy stores and allowing a parallel and a series connection between the two electrical energy stores. The electric circuit includes at least one fourth switching unit and one fifth switching unit electrically connected to one pole connector each and to one consumer connection. The consumer connection is makes electrical contact with an electrical consumer or a charging unit. The switching units are switchable between an electrically disconnecting and connecting states. The fourth and fifth switching units are galvanically isolating in an electrically disconnecting state. The first switching unit, the second switching unit, and the third switching unit are designed as semiconductor components.

摘要： An electric vehicle includes a reconfigurable energy storage system with a first submodule and a second submodule. An interface circuit is operable to transfer a charging power to the reconfigurable energy storage system from a charging station that is external to the electric vehicle. A switching circuit is operable to electrically arrange the first submodule and the second submodule in series or in parallel. A diode is operable to convey the charging power between the first submodule and the second submodule while the reconfigurable energy storage system is arranged in series and the charging power is present. A bias circuit is operable to maintain a reverse bias across the diode while the reconfigurable energy storage system is arranged in series and the charging power is absent.

摘要： An electric propulsion system includes a rotary electric machine having an output member, a rechargeable energy storage system (“RESS”) connected to the electric machine, a user interface device, and a controller. The RESS includes multiple battery modules and a switching circuit, the latter being configured, in response to electronic switching control signals, to connect the battery modules in a parallel-connected configuration or a series-connected configuration, as a selected battery configuration. The user interface device receives an operator-requested drive mode request as an electrical signal indicative of a desired drive mode of the electric propulsion system. The controller, which is programmed with mode-specific electrical loss information associated with the desired drive mode, establishes the selected battery configuration in response to the drive mode request, and presents a drive mode recommendation via the user interface device when the loss information associated with the desired drive mode exceeds a calibrated loss threshold.

摘要： Electrically powered vehicles with redundant power distribution circuits employ inverters and a multi-phase alternating current (AC) motor. An electrically powered vehicle includes batteries, inverters, interphase transformers, and a three-phase AC motor. Each of the inverters generates a three-phase AC input from power supplied by an associated one of the batteries. The interphase transformers generate drive phases for the AC motor from the three-phase AC inputs generated by the inverters.
