A battery system, a method of detecting leaks inside a battery system, and a vehicle, the battery system including a housing including a housing frame and a base frame, the housing frame and the base frame enclosing a housing space; a battery module including a plurality of battery cells electrically connected to each other via a bus bar, the battery module being in the housing space; a tray including a tray frame and a tray base; and a battery management system including a liquid detector, wherein the liquid detector is configured to detect a liquid inside the tray, and the liquid detector includes a high-voltage conductor, a first end of the high-voltage conductor being connected to the bus bar and a second end of the high-voltage conductor being between the base frame and the tray base.

Battery system, method for leakage detection inside the battery system, and vehicle including the battery system

A relay including a relay coil and a relay switch. The relay coil including a coil beginning and a coil end and being connected to a relay driving circuit. The relay switch being arranged in a load circuit. A first parasitic capacitance between the coil beginning and the relay switch is different than a second parasitic capacitance between the coil end and the relay switch.

Relay and battery system including the same

A high voltage battery for a motor vehicle and which includes cells and a system for controlling and monitoring the cells and the functioning of the battery system.

High voltage battery system for a vehicle

A device for detecting the insulation resistance of a high-voltage battery system of a motor vehicle that includes a high-voltage battery and a high-voltage component which is operatively connected to terminals of the high-voltage battery via converters. The device includes a reference resistor operatively connected to the terminals of the high-voltage battery via switches, with a voltage measurement device configured to detect the voltage present between each respective terminal and a reference potential of the vehicle; a voltage measurement device configured to measure the voltage between the terminals; and a coupling circuit configured to monitor the high-voltage component when the contactors are open.

Device for detecting the insulation resistance of a high voltage battery system

A battery control device having a battery system having a plurality of cells, a first electronic unit, a second electronic unit having a ground potential operatively connected to a potential of the battery system, a communication link including an electric isolation and a communication line having an electromagnetic shielding at least in sections, the communication link being configured to operatively connect and enable communication between the first electronic unit and the second electronic unit.
