Abstract: A motor vehicle having an access area for extinguishing a battery fire. The motor vehicle includes a high voltage battery with a battery housing and at least one battery cell, a receiving area in which the high voltage battery is received, a side wall which bounds the receiving area in one direction, and an access area which is positioned in the side wall and through which an extinguishing device can be introduced at least partially into the receiving area from a side of the side wall facing away from the high-voltage battery. The receiving area has at least one defined dead area associated with the access area, in which no battery cell is arranged.

Abstract: Miniaturized electrical connector systems are disclosed herein. In exemplary aspects disclosed herein, the connector system includes a twinaxial female connector having a housing and at least one dielectric positioned therein. The at least one dielectric defines two parallel channels configured to receive at least a portion of two conductors of a twinaxial cable. The twinaxial female connector includes an oval interface configured to orient and align the conductors of the twinaxial cable with mating pins of a male connector. The twinaxial female connector further includes two spring-type interconnects positioned within the oval interface, each configured to directly contact a conductor of the twinaxial cable and a mating pin of the male connector. The twinaxial female connector further includes a retaining clip attached to an exterior of the housing with a lever arm biased towards and pivotable from an engaged orientation. Such features reduce the manufacturing complexity, cost, and overall size.

Abstract: A compressible electrical contact, manufactured from a tube, includes a first contact end, a second contact end opposing the first contact end, and a medial portion disposed between the first contact end and the second contact end. The medial portion includes a plurality of divaricated cut sections based on at least one divaricating pattern cut into the tube. The at least one divaricating pattern preferably includes an upper tapered section and a lower tapered section such that a plurality of tapered slots are formed after the tube is cut and when the compressible electrical contact is substantially compressed.

Abstract: A method for passivating a metal surface of a light-weight metal part is disclosed, wherein a conversion layer is applied to the surface of the light-weight metal part in a passivation step. A passivation step is carried out wherein an aqueous passivation solution is used to create a calcium phosphate-containing conversion layer (5) on the metal surface of the part, said conversion layer comprising oxides and hydroxides from the material of the part and from the passivation solution and containing amino acids.

Abstract: A DC high power distribution system provides power to a load in parallel with one or more storage capacitors. The system includes a hot-swap controller and an array of parallel-connected transistors connected in series between a DC source and the capacitors/load. A power contactor is connected in parallel to the transistor array, both of which are connected to control outputs of the controller. The controller monitors various circuit conditions of interest, such as input over-voltage, input under-voltage, and over-current. If the circuit conditions meet designated parameters, the controller activates the transistors for charging the capacitors, for limiting inrush current. After charging, the controller activates the power contactor for shunting the transistors and carrying the 150+ ampere current during ongoing operation. If any of the monitored circuit conditions fail to meet designated parameters, the controller halts operation of the circuit by deactivating the power contactor and/or transistors.
