Abstract: The present disclosure refers to a ventilation device for a battery, particularly to a multifunctional breathing and venting device for a casing of one of a battery submodule, battery module or battery system, such as for an electric vehicle and an energy storage system (ESS). The ventilation device comprising a housing configured for being attached to a vent opening of a battery casing in a sealing manner and comprising at least one lateral wall, a breathable filter separating an interior of the battery casing from a breathing chamber within the housing, a venting membrane separating the breathing chamber from an exterior environment in a gas tight manner, and a breathing sprout fluidly connecting the breathing chamber and the environment and bypassing the venting membrane. The disclosure further relates to a battery comprising such a ventilation device attached to its casing.

Abstract: A male connector for a cooling pipe is provided. The male connector includes a hollow cylindrical base having a first end having a chamfered outer circumferential edge and a second end. The base includes a circumferential notch adjacent to the first end and configured to receive an O-ring and an elastic pin integrally formed with and protruding from a surface of the base. An acute angle formed between the surface of the base and the elastic pin has a vertex pointing toward the first end of the base.

Abstract: A battery system having at least one battery cell, an absorption element, and a temperature-control system having a liquid temperature-control medium configured to cool and/or heat the battery cells in a battery housing, and a motor vehicle having such a battery system.
