摘要:
The invention proposes a battery cell unit (100) comprising at least one housing (10) in which at least one battery cell (11) is arranged, wherein the housing has at least one receptacle (20) in which a first connection element (21) for connecting the battery cells (11) to an external device is arranged. The battery cell unit has a control electronics system and also at least one second connection element (22) which is arranged at a distance from the first connection element (21) in the receptacle (20) and is electrically conductively connected to the battery cell (11), so that electrical energy and/or data can be transmitted by means of the second connection element (22).

The invention relates to a battery pack (50) comprising a housing (72) in which at least one battery module (60) having at least one battery cell (2) is arranged, as well as a cooling system for cooling said at least one battery cell (2). The cooling system at least comprises a cooling plate (62) arranged outside the housing (72), said at least one cooling plate (62) lying flat against a cover plate (80) of the housing (72) and heat dissipating from the at least one battery cell (2) to the cooling plate (62) through said cover plate (80).
摘要:
The invention relates to a piezo-electric actuator (1), which is used in particular as an actuator for fuel injection valves, comprising an actuator body (3), which has a plurality of ceramic layers (4) and a plurality of electrode layers (5, 6) arranged between the ceramic layers (4), and outside electrodes (7, 8), which are alternately in electrical contact with the electrode layers (5, 6). The outside electrodes (7, 8) are formed of corrugated metal sheets (7, 8), which preferably have corrugations (16, 17) that are arranged obliquely with respect to the longitudinal axis (10) of the actuator body.

Disclosed is a valve mechanism, especially a fuel injection valve for an internal combustion engine, comprising a valve element whose switching position at least indirectly depends on the switching mode of a piezo actuator. Said piezo actuator is impinged upon by a tubular and overall cylindrical biasing device (30) that is made from a plate-shaped starting material and is provided with two abutting longitudinal edges (42, 44) such that the longitudinal rigidity is modified in said area. The inventive biasing device (30) encompasses at least one zone (52) whose longitudinal rigidity is different from that of an adjacent zone and which is disposed relative to the abutting longitudinal edges (42, 44) in such a way that the bending moment (M) which is generated as a result of the modified longitudinal rigidity in the area of the abutting longitudinal edges (42, 44) and acts upon the piezo actuator is reduced.
