摘要： Welding electrode arrangement and method for welding one interconnector of two adjacent electrochemical cells of a rechargeable battery. The two electrochemical cells are disposed to be separated by means of a housing partition. The interconnectors are disposed to face one another on two opposite sides of the housing partition. An opening is disposed in a region of the housing partition. The method comprises contacting the interconnectors with a welding electrode arrangement. The welding electrode arrangement has at least one pair of welding electrodes. One welding electrode of the at least one pair of welding electrodes contacts in each case one of the interconnectors by means of an insert part. The method further comprises welding the interconnectors in such a manner that the material of the interconnectors melts at least in regions and is connected in a materially bonded manner through the opening in the housing partition.

摘要： A sealing plug arrangement for sealing a combined filling and degassing opening of an accumulator. The sealing plug arrangement includes at least one valve part, one valve holder, and one sealing plug. The valve part is arranged on the valve holder and forms an openable valve mechanism with the valve holder for sealing at least one interior space of the accumulator from the surrounding area upon pressurization. The sealing plug includes at least one fastening means for fixing to the filling and degassing opening and at the same time subjecting the valve part to a pretensioning force toward the valve holder. The valve holder includes at least one extension axially projecting toward the valve part which is formed as a circumferential sealing edge on a surface facing the valve part on which the valve part rests.

摘要： A compact AGM lead acid battery is disclosed. The battery has a container and one or more electrically connected cells in the container. The electrically connected cells are formed by a plurality of positive plates and plurality of negative plates, wherein an absorbent glass mat is interleaved between positive and negative plates. Electrolyte is provided within the container. The lead acid battery has an improved battery performance per volume and less lead weight than a conventional AGM lead acid battery or EFB lead acid battery.

摘要： The invention relates to an energy storage system for a vehicle, in particular a starter battery for a vehicle, having a plurality of energy storage cells for providing and/or storing electric energy and a housing which has a plurality of wall elements that delimit the interior of the housing. The housing is designed to receive the plurality of energy storage cells in the interior of the housing. A plurality of separating walls are arranged in the interior of the housing in order to divide the interior of the housing into a plurality of chambers, wherein each chamber is designed to receiving an energy storage cell. A fluidic connection is formed between the individual chambers, and a ventilation valve is arranged on one of the wall elements, preferably a cover element, of the housing in a respective region paired with the corresponding chamber. At least one of the ventilation valves is an active ventilation valve, and the remaining ventilation valves are blind closures.

摘要： Disclosed is a connection pole for a rechargeable battery. The connection pole has a connection region for securing a pole terminal to the connection pole, and a securing region for securing the connection pole to a housing part of the rechargeable battery. The connection region is in particular of circular or substantially circular form at least at its end facing the securing region, wherein a circumferential region is provided in an end region, which faces the connection region, of the securing region, which circumferential region at least substantially has a ring shape and, for the purpose of preventing rotation of the connection pole, has on its outer circumference a tooth system projecting radially from the circumferential region. Here, the diameter of the substantially ring-shaped circumferential region is consistently smaller than the diameter of that end of the connection region which faces the securing region.
