Description

System with a stacking aid and a plurality of batteries The invention relates to a system with a stacking aid and a plurality of batteries arranged in the stacking aid, in particular AGM batteries, wherein the stacking aid has a support element and two cheeks aligned orthogonally thereto, which receive the support element between them, wherein the support element receives a plurality of batteries arranged in rows one above the other, wherein between two rows of batteries following one another in the vertical direction a positioning aid is arranged, which has a plate equipped with an extension serving as a stop. Systems of the type mentioned above in general and systems of the type mentioned above for AGM batteries in particular are known from the state of the art, which is why separate written proof is not required at this point. A generic system is known, for example, from DE 102022 118 386 A1, which relates to a system in particular for AGM batteries. AGM batteries are rechargeable batteries that have electrode plates arranged in a housing. The housing is rectangular in cross-section and has first side walls that run parallel to one another on the one hand and second side walls that run parallel to one another on the other. The electrode plates held by the housing are aligned parallel to the first side walls of the housing. The second side walls of the housing run perpendicular to the electrode plates. A fleece that serves as a separator is arranged between two adjacent electrode plates. The housing also holds an electrolyte that surrounds the electrode plates. In the case of AGM batteries, this is in bound form and is provided by the fleeces located between the electrode plates. The fleeces therefore not only serve as separators, but also as an electrolyte bond. The electrolyte present in AGM batteries in bound form makes it possible to store AGM batteries lying down, i.e. on one of the side walls of the housing without the risk of electrolyte leaking from the housing. To ensure long-lasting usability of AGM batteries, there must always be surface contact between the individual electrode plates and the fleeces arranged between them and filled with electrolyte. To ensure this, plate packs consisting of the electrode plates and the individual fleeces arranged between them are inserted into the housing of the AGM battery in a compressed state. However, when used as intended, the internal pressure that develops in the housing can cause the housing to bulge or bulge, which then means that the compressed arrangement of the electrode plates and fleeces can no longer be maintained despite the plate packs having been pressed together beforehand. This has the negative effect that the contact between the electrode plates and the fleeces decreases, resulting in a significant reduction in the service life of the AGM battery. The pressure inside the housing of an AGM battery can increase, particularly during a charging cycle, which repeatedly leads to a reduction in contact between the electrode plates and fleeces, reducing the service life. The loading condition caused by the compressed fleece is therefore the main cause of the bulging of the casings. To counteract this problem, it has already been proposed to store AGM batteries lying on shelves, with the AGM batteries aligned in relation to the shelf in such a way that the electrode plates are aligned parallel to the shelves. In the intended use, the AGM batteries are virtually clamped between two shelves in order to counteract unwanted bulging of battery casings, as described, for example, in DE 202019 105 870 U1. Comparable systems are also known from US 6,641,951 B1 and EP 0 922 308 B1. Here too, stacking aids are used to accommodate AGM batteries, which house the AGM batteries held by them, with supporting elements in the form of intermediate and/or insert floors being provided, which are connected to laterally arranged cheeks in a force-transmitting manner. When used as intended, The AGM batteries are therefore clamped at least between a base element and an intermediate and/or insert base on the one hand and an intermediate and/or insert base and a cover element on the other, whereby the base element, the cover element and the at least one intermediate and/or insert base counteract any unwanted bulging of the housing of an AGM battery. In the event of a force being applied to the base element, the intermediate and/or insert base and/or the cover element as a result of counteracting a bulging of the housing of an AGM battery, the force is dissipated via the side cheeks of the stacking aid, which are operatively connected to the at least one intermediate and/or insert base in a force-transmitting manner. All of these previously known systems and stacking aids have the disadvantage that they are very robust due to the use of appropriate materials, in particular to ensure that the forces can be dissipated via the side walls. The high use of materials due to the
