A method of operating a charging system may include connecting the charging system to a power grid with a plurality of phases, measuring a plurality of phase currents of the plurality of phases at a balance point, and transmitting a plurality of performance targets to a plurality of electrical consumers connected to one of a plurality of charging points of the charging system. The method may also include changing a performance target of the plurality of performance targets for each of the plurality of charging points individually for a predetermined test time interval and measuring a corresponding change of the plurality of phase currents at the balance point. The method may further include, based on the corresponding change of the plurality of phase currents, determining whether an electrical consumer charges with a significant current and whether the electrical consumer could charge with a higher current.

Method of operating a charging system with multiple charging points

A method for charging electric consumers at an electricity grid with multiple phases may include measuring a phase current of each of the multiple phases of the electricity grid at a balance point. The method may also include determining to which of the multiple phases each electric consumer of the electric consumers is connected for charging via the balance point. Additionally, the method may include holding an unbalanced load of the multiple phases below an unbalanced load threshold value via communicating a power specification to each electric consumer connected for charging.

Method for charging electric consumers

A vehicle may include an internal combustion engine having a crankcase and a supercharging apparatus, and a crankcase ventilation apparatus having at least one oil-separating apparatus including at least one oil separator. An oil return line may communicate separated oil from the crankcase ventilation apparatus to the crankcase. An ejector pump may be driven via a compressed air flow of the supercharging apparatus and may be configured to generate an underpressure for driving a blow-by gas. The crankcase ventilation apparatus may include a pump control valve configured to at least one of regulate and control the compressed air flow through the ejector pump.

Crankcase ventilation apparatus

A spiral compressor may include a stationary first spiral member and an orbiting second spiral member intermeshing with the first spiral member. The spiral compressor may include a pendulum slide mechanism that may have an inner ring and a stationary outer ring connected to the inner ring via a plurality of pendulums. The pendulum slide mechanism may include an eccentric member disposed on a radial inside of the inner ring with respect to a central access of the inner ring. The inner ring on an inner circumferential side may be drivingly connected to the eccentric member and on an outer circumferential side may be rigidly connected to the second spiral member. The second spiral member may transmit an orbiting motion in relation to the first spiral member via the pendulum slide mechanism when the eccentric member is driven.

A charge air cooler for an internal combustion engine is disclosed. The charge air cooler includes at least one connecting piece for connection to at least one cooling circuit configured to conduct coolant. The charge air cooler includes at least one coolant pump for circulating the coolant. The at least one coolant pump is integrated in at least one flow path within the charge air cooler.
