Abstract: Systems and methods are provided for modularizing a system. Parallel power systems having electronically isolated high voltage systems facilitate modulization. A control system is provided that optimizes the distribution of a power demand and/or a torque request so as to keep the efficiency, durability, drivability and/or safety of the system within an optimum range. In some cases, the distribution of power is uneven, so as to extend the battery life, while in other cases, the power draw on battery systems are kept equal and constant so as to properly manage the state of charge of the parallel power systems. In still other cases, the chosen power distribution keeps the power demand and/or torque request between minimum and maximum levels/capacity, and the power distribution avoids on/off of an individual power system.

Abstract: A powertrain for an electric vehicle has a driveshaft connected to two or more motors where each motor is connected to a battery pack associated with that motor. A controller is used to select one or more motors to be energized for propulsion or used for regenerative braking to recharge the battery pack to which it is coupled. The controller can optimize the state of charge (SOC) difference of the battery packs and provide for a smooth and efficient powering of the vehicle for acceleration and climbing and optimize the range of the vehicle by management of the relative SOC of the battery packs. The electric vehicle can include two or more fuel cells that individually coupled to a motor.

Abstract: Braking of a vehicle and a trailer can be balanced when regenerative braking of the vehicle is activated. The activation of regenerative braking of the vehicle can be detected. Responsive to detecting that regenerative braking of the vehicle is activated, one or more brakes of the trailer can be caused to be activated. Thus, the braking effectiveness of the vehicle and the braking effectiveness of the trailer can be substantially balanced. As a result, a possible push force from a trailer to the vehicle towing the trailer can be reduced, which, in turn, can help to avoid unwanted movements of the trailer (e.g., swaying or jackknifing).

Driving conditions associated with a fuel cell vehicle can be obtained. Based on the driving conditions, power sources of the fuel cell vehicle to provide power to fuel cell vehicle system can be determined, the power sources comprising the fuel cell stack and the two supplemental batteries. Operating conditions of each of the power sources can be assessed, and one or more of the power sources can be controlled to deliver power to the fuel cell vehicle system based on the operating conditions of each of the power sources.
