A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices. To charge, the machines employ electrical current from an external source. As demand at individual collection, charging and distribution machines increases or decreases relative to other collection, charging and distribution machines, a distribution management system initiates redistribution of portable electrical energy storage devices from one collection, charging and distribution machine to another collection, charging and distribution machine in an expeditious manner. Also, redeemable incentives are offered to users to return or exchange their portable electrical energy storage devices at selected collection, charging and distribution machines within the network to effect the redistribution.

A vehicle power supply system is provided. The vehicle power supply system includes a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter, a charging and discharging control device that operates the inverters and the voltage converter, and a second regeneration permission upper limit setting unit that sets a threshold for a second SOC of the second battery. The charging and discharging control device prohibits the second battery from being charged in a case where the second SOC is larger than the threshold during regenerative deceleration, and the second regeneration permission upper limit setting unit changes the threshold to a second regeneration permission upper limit or a second normal upper limit on the basis of a state of the first battery.

A vehicle includes an accelerator pedal, a brake pedal, an electric machine, friction brakes, and a controller. The electric machine is configured to propel the vehicle and to brake the vehicle during regenerative braking. The friction brakes are configured to brake the vehicle. The controller is programmed to, responsive to an operator selection of a one-pedal drive mode, decrease vehicle speed via regenerative braking in response to releasing the accelerator pedal. The controller is further programmed to transition the vehicle to an inhibit state in which the friction brakes are applied to prevent vehicle creep in response to receiving an automated signal to disable the one-pedal drive mode and vehicle speed becoming zero while the one-pedal drive mode is selected.

A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. By default, each portable electrical energy storage device is disabled from accepting a charge unless it receives authentication information from an authorized collection, charging and distribution machine, other authorized charging device, or other authorized device that transmits the authentication credentials. Also, by default, each portable electrical energy storage device is disabled from releasing energy unless it receives authentication information from an external device to which it will provide power, such as a vehicle or other authorization device.

A heat management system for a fuel cell vehicle propelled by an electric traction motor includes a fuel cell system comprising a fuel cell configured to generate electric power when receiving hydrogen through a hydrogen inlet and oxygen through an oxygen inlet, wherein the fuel cell includes an outlet configured to expel exhaust water formed in the fuel cell, and a compressor including an inlet configured to receive ambient air, and an outlet, wherein the inlet of the compressor is arranged in downstream fluid communication with the outlet of the fuel cell and configured to pressurize a mixture of exhaust water expelled from the fuel cell and ambient air.
