摘要:
The invention relates to a battery (10) having a control device (14), which further comprises an interface (16) which is suitable for enabling a measurement of the battery properties and/or of a discharge of the battery (10), in the event that the control device (14) has failed. In addition, a motor vehicle, in particular an electrical motor vehicle, is provided, which comprises a battery (10) according to the invention. The invention further relates to an analysis plug which is designed to replace the maintenance plug (16) of a battery (10) according to the invention. In addition, a method for monitoring a battery (10) is provided, wherein a measurement of the battery properties and/or of a discharge of the battery (10) via an interface (16) is made possible, in the event that the control device (14) has failed.

The invention relates to a battery comprising a housing in which at least one battery cell and a device for drying air present in the housing inner chamber are arranged. The battery according to the invention is characterised in that the battery (1) comprises a moulded body (7) made of a porous, moisture-absorbing material which is disposed such that it extends both into the housing inner chamber (3) and into the outer chamber of the housing (2) and connects said chambers to each other such that moisture can be conducted therebetween. The part of the moulded body (7) present in the housing inner chamber (3) is connected to the device (5) for drying the air present in the housing inner chamber (3) such that collected water (6) can be transferred out of the device (5) to the moulded body (7) for air drying.

The invention relates to a battery. The battery comprises a housing (1) and a plurality of battery cells (2) arranged in the housing. According to the invention, each battery cell (2) has at least one discharge valve (3). The battery further comprises a discharge pipe system for discharging gases released from one, a plurality of or all discharge valves (3) of the battery cells (2). The discharge pipe system according to the invention has a plurality of separate connections (4) for receiving the released gases and a common discharge guide (5) into which the separate connections (4) open and via which the released gases can be discharged out of the housing (1). The battery according to the invention is characterized in that a protective film (7) is arranged between the discharge valves (3) of the battery cells (2) and the separate connections (4) of the discharge pipe system so that direct contact of the battery cells (2) to the gases in the discharge pipe system is prevented.

The invention relates to a pressure equalization element for a housing (10) having a water-impermeable membrane (16), wherein the membrane (16) is combined with a pressure relief valve acting in two directions or with a corresponding combination of two pressure relief valves (18) such that the volume of the air exchange is reduced. The amount of moisture transported into the housing (10) is thus also reduced. The invention further relates to a housing (10) comprising a pressure equalization element (11), to a lithium ion accumulator having a housing (10), and to a motor vehicle.
