A vehicle including a high-voltage electric battery assembly including first and second battery cell modules and DC/DC electric power converter assembly is described. The DC/DC electric power converter assembly selectively converts electric power from the first battery cell module and the second battery cell module. A second end of the DC/DC electric power converter is electrically connected to a low-voltage system. The low-voltage system includes a first subsystem configured to provide a critical vehicle operation. A controller includes algorithmic code executable to monitor the high-voltage battery assembly, including, upon detecting a fault in the first battery cell module of the high-voltage battery assembly, controlling the DC/DC electric power converter assembly to electrically convert electric power from the second battery cell module to low-voltage electric power that is transferred to the first subsystem.

Method and apparatus for controlling a DC/DC power converter

A multi-mode powertrain system including an internal combustion engine, a high-voltage electric machine and a high-voltage electric power system is described. A method for controlling the multi-mode powertrain system includes, in response to an operator initiating a jumpstart, electrically connecting the high-voltage electric power system to a remote electric power source and energizing contactors between the high-voltage electric power system and the remote electric power source. Electric power flow through an auxiliary power module electrically connected to the high-voltage electric power system that supplies electric power to an accessory device is minimized. Engine starting parameters are modified, and the internal combustion engine is started by controlling, via a controller, the high-voltage electric machine to spin the internal combustion engine, and controlling operation of the internal combustion engine based upon the modified engine starting parameters to effect starting.

Jumpstarting an internal combustion engine

A product for use with a vehicle may include a high voltage electrical storage system unit. An energy storage unit may supply power to a high voltage wakeup module. The high voltage wakeup module may connect and may disconnect a number of loads from the energy storage unit when the vehicle is operating or shut down.

Single battery architecture for electrification vehicle

An electrical system includes a battery for providing electrical power to a starter mechanism and an auxiliary load of a hybrid-electric vehicle. An electric double-layer capacitor ('EDLC') is electrically connectable to the battery and the auxiliary load. A separation switch is electrically connected between the battery and the EDLC for electrically separating the battery from the EDLC and the auxiliary load. The separation switch is opened in response to the voltage across the battery being less than the voltage across the EDLC.

Electrical system and method for a hybrid-electric vehicle

A van camper including door panels in the side and rear walls thereof that are outwardly, downwardly pivotable about a lower hinge so to form bed platforms for sleeping thereupon, a canvas canopy detachable snap fastened around each doorway extending over the horizontal bed platform, hydraulic shock absorbers for gently lowering the door and a winch with cable to raise the door into vertical closed position.
