Electrical circuit arrangement for an energy storage system comprising a first electrochemical energy storage device and a second electrochemical energy storage device.

Electrical circuit arrangement for an energy storage system and method for operating said electrical circuit arrangement

A battery module () for a motor vehicle. The battery module () includes a battery unit (), a negative pole (), a positive pole (), a switching unit (), which is connected electrically in series with the battery unit () and has at least one controllable switching element, and a management system () for controlling the at least one switching element. A hold circuit () is provided, which is connected to the management system () and to the switching unit () in such a way that a control signal from the management system () can be transferred through the hold circuit () to the switching unit (), and is designed such that, in an active state of the hold circuit (), a control signal from the management system () to open the at least one switching element can be transferred to the switching unit () with a time delay.

Battery module for a motor vehicle, and motor vehicle

The present invention relates to a circuit arrangement for switching a high-voltage MOSFET () for precharging an intermediate circuit capacitance of a high-voltage on-board network with a first circuit assembly (), by means of which the switching times of a high-voltage MOSFET used for charging the intermediate circuit capacitance can be reduced.

Circuit arrangement for precharging an intermediate circuit capacitance of a high-voltage on-board network

A spark plug for an internal combustion engine, including an electrical connecting arrangement on a connection-side end, an end on the combustion-chamber side pointing toward a combustion chamber, an insulator and a housing having a thread for attaching the spark plug to an engine component, a first sealing area and a second sealing area being provided between the insulator and the housing, the first sealing area being situated closer to the connection-side end and the second sealing area being situated closer to the end on the combustion-chamber side, a tool engagement area for transmitting a torque to the spark plug for fitting or removing the spark plug being situated in an area of the spark plug which lies between the connection-side end and the first sealing area.

Spark plug having a reduced physical volume

An electrode material based on an alloy or mixed compound, the alloy or mixed compound containing at least two of the elements platinum, palladium, iridium, rhenium, rhodium or ruthenium and, in addition, at least one oxide of the elements zirconium, hafnium, yttrium or magnesium.

Spark plug with specific electrode material

A spark plug which includes an end at its combustion chamber end, and an end at its connecting end, as well as a housing and an insulator situated in the housing. The insulator has a longitudinal bore having a longitudinal axis, a center electrode situated in the longitudinal bore of the insulator, a first ground electrode which extends into the region of the longitudinal axis of the insulator, and a second ground electrode which is situated at a distance from the longitudinal axis of the insulator laterally next to the center electrode. The insulator has a front section, facing the first ground electrode, which has an end face. The insulator has an outside diameter d and an inside diameter c, d&#x2212;c, that is, the difference between outside diameter d and inside diameter c, in the front section of the insulator being not greater than 1.9 mm.
