AI Technical Summary

Technical Problem

Existing sensor installations for battery systems, particularly automotive batteries, require complex sealing measures due to the need for cables to connect sensors outside the battery housing to a control unit, leading to high installation effort.

Method used

An inductive excitation and/or readout unit with a coupling coil embedded in a plastic body, featuring electrical contact elements that protrude for plug connections, allowing for simple and sealed integration into a housing wall, enabling conductive connection to a control unit without routing cables through the wall.

Benefits of technology

Facilitates easy and sealed connection of the excitation and/or readout unit to a control unit, reducing installation complexity and ensuring a fluid-tight seal while allowing for efficient battery monitoring.

Abstract

The invention relates to an inductive excitation and / or readout unit (20) for a sensor (24) for a battery (16), wherein the excitation and / or readout unit (20) comprises a coupling coil (36) and a pair of terminals (50) electrically connected to the coupling coil (36), the terminals having a first and second electrical contact element (50a, 50b). The excitation and / or readout unit (20) comprises a plastic body (52) having a first side (52a) and a second side (52b) opposite the first side (52a) with respect to a first direction (z), wherein the coupling coil (36) is embedded in the plastic body (52) and at least a portion of the respective first and second electrical contact elements (50a, 50b) protrudes from the first side (52a) of the plastic body (52) to provide an electrical plug connection.
