Abstract: A system for supplying electric power to components of an agricultural harvester may include a power storage device and a first agricultural harvester component. The system may also include a first bus electrically coupled to the power storage device and configured to supply electric power at a first voltage to the first agricultural harvester component. Furthermore, the system may include a second agricultural harvester component and a second bus configured to supply the electric power at a second voltage to second agricultural harvester component, the second voltage being less than the first voltage. Additionally, the system may include a converter electrically coupled between the first and the second bus, with the converter configured to reduce the first voltage supplied through the first bus to allow electric power to be supplied to the second agricultural harvester component at the second voltage via the second bus.

Abstract: A power-supply and recharge group for an electric vehicle comprising: a first battery pack; a second battery pack; a first DC-to-DC converter; a second DC-to-DC converter; a low-voltage power-supply source; and a control unit configured to: detect a charge difference between a first and a second battery pack; transfer an electric current from a low-voltage power-supply source to the one of the first and second battery pack having a lower charge, until said charge difference is cancelled; connect the first and the second battery pack to one another in series and recharge them by means of a recharge station on the outside of the vehicle. A direct connection between the DC-to-DC converters can replace the auxiliary low-voltage source.

Abstract: A recharging method and assembly to charge an electric vehicle comprising a battery pack including a plurality of storage batteries having a same nominal charge voltage, the battery pack being connectable to a recharging station adapted to provide a recharging voltage, which is greater than said nominal charge voltage. In a recharging mode, in which the recharging voltage deliverable by the recharging station is equal to or greater than the sum of the nominal charge voltages of the plurality of storage batteries, the storage batteries are connected in series to one another, so as to recharge the series of batteries with a recharging voltage greater than the nominal charge voltage.
