    摘要: A starting module for a vehicle is provided. The starting module is configured to reside on-board the vehicle, and is used to start an engine associated with the vehicle in the event the battery on the vehicle is too weak to crank the engine. The engine starting module first comprises a housing. The housing resides proximate the vehicle battery and holds a plurality of super capacitors. The super capacitors reside within the housing, in series, and are electrically in parallel with the vehicle battery. The super capacitors store charge received from the electrical system of the vehicle. The starting module also includes control logic. The control logic controls the release of energy from the super capacitors. The engine starting module also comprises an isolation switch, which is configured to move between open and close positions in response to signals from the control logic.

    摘要: An electrical system for a vehicle having an internal combustion engine with start/stop capability includes a primary battery connectible to an engine starter motor; a secondary battery, an alternator, and an electrical load in parallel with one another and selectively connectible in parallel with the primary battery by a charge switch; in parallel with the secondary battery, a DC/DC converter in series with a third electrical energy source; and a bypass switch operable to selectively bypass the DC/DC converter. The bypass switch allows for selective bypassing the DC/DC converter and charging/discharging of the third electrical energy source during start/stop operation, to ensure a sufficient voltage level over the additional vehicle electrical loads when the internal combustion engine and consequently the alternator are not running.

    摘要: A vehicle electric power supply apparatus includes first and second power sources connected in parallel to each other; a DC-DC converter connected between the first and second power sources; a switch connected in parallel to the DC-DC converter and connected between the first and second power sources; an opening and closing unit that is operable to open and close the switch; and a control unit that controls the DC-DC converter and the opening and closing unit. When an internal combustion engine is stopped, the control unit sets the switch to be OFF using the opening and closing unit, and the control unit causes the second power source to be discharged and the first power source to be charged until the output voltage of the second power source reaches a first voltage by electric power supply from the second power source to the first power source via the DC-DC converter.
