    Abstract: A system performs a method of converting regenerative braking energy in an eco-friendly vehicle. When an amount of remaining battery power reaches or exceeds a predetermined threshold during regenerative braking, a controller of the system in which a battery pack and a passenger air-conditioning apparatus are connected by a coolant circulation line connected to a battery chiller to which an outer refrigerant line is connected, controls: consumption of the regenerative braking energy by a compressor; switching of the flow of an air-conditioning refrigerant by a 4-way valve toward a condenser or radiator of an outer heat exchanger; evaporation of the air-conditioning refrigerant by expansion operation of an expansion valve in the direction of a battery chiller or an expansion valve in the direction of the outer heat exchanger; and operating of the outer heat exchanger for heat release or absorption to or from the outside.

    Abstract: A vehicle includes two or more battery packs configured to power a motor. A controller is configured to dynamically activate an operational mode during operation. The operational mode is one of multiple possible operational modes including a first operational mode defining a series connection between the two or more battery packs and second operational mode defining a parallel connection between the two or more battery packs. The connection between the battery packs is controlled by a first plurality of switches. A plurality of low voltage loads are connected to a subset of the battery packs in the battery packs such that a power output of the subset of the battery packs provides full power to the plurality of low voltage loads. The plurality of low voltage loads are connected to only the subset of the battery packs in both the first operational mode and the second operational mode.

    Abstract: The disclosure relates to a work machine, comprising a primary energy source for feeding electric energy into a link, a gear for performing a task of the work machine, at least one electric drive connected to the link in order to operate the gear of the work machine, a holding brake for fixing or releasing the gear, and an energy store which is connected to the link in order to provide electric energy demanded from the link upon actuation of a gear and/or to absorb electric energy fed into the link. According to the disclosure, during an emergency lowering of the gear, the at least one electric drive to convert the kinetic energy into electric energy and to feed it into the link. In the event of an unavailability or failure, the primary energy source is configured to absorb the energy fed into the link by the electric drive.
