Embodiment Construction

[0058] Although the described embodiments relate to lead accumulators with free acid, it should be clear that the proposed solution is also applicable to other types of accumulators.

[0059] Covers for accumulators and related accumulators are listed as subject of this invention in figure 1 , where they are denoted by reference numerals 1 and 100, respectively.

[0060] The accumulator 100 basically comprises a cover 1 which closes the top of a container 2 in which a plurality of vertical partition walls 3 are arranged which delimit the primary cells 4 of the accumulator 100 .

[0061] Each galvanic cell 4 is suitable for holding an electrolyte E and containing a set of plates 5 electrically connected together so as to be able to form the positive and negative terminals P and N of the accumulator 100 .

[0062] The present invention is intended to define a storage tank 6 in the lid 1, which can be formed by Figures 2 to 4 It can be seen that the storage tank 6 is suitable ...

Abstract

The invention concerns a cover ( 1, 101, 102, 103, 104, 105 ) for an electric accumulator ( 100 ) adapted to be integral with the container ( 2 ) of the accumulator ( 100 ) and a relative accumulator ( 100 ). The cover ( 1, 101, 102, 103, 104, 105 ) comprises: a reservoir ( 6 ), adapted to contain a topping up liquid (R) of the electrolyte (E) present in the cells ( 4 ) of the accumulator ( 100 ), communicating through a supply duct ( 7 ) with the cells ( 4 ); control tneans ( 9 ) of the level (L) of the electrolyte (E) in the cells ( 4 ) adapted to prevent / allow the flow of topping up liquid (R) when the corresponding level (L) of the electrolyte (E) is higher / lower than a predetermined level (S).

Description

technical field [0001] The invention relates to a cover for accumulators, especially suitable for manufacturing lead accumulators with free acid liquid and related accumulators. Background technique [0002] As is known, the housing of an accumulator comprises a cover which closes a container inside which is provided with partition walls. These elements define a galvanic cell within which positive and negative electrodes or plates are spaced apart. [0003] Plates with the same polarity are connected together to form positive and negative sets respectively and as an integral component. The different elements are connected in series with each other and their number varies according to the nominal voltage of the battery. In the case of a 12V starter battery, the number of elements, and thus the number of primary cells, is equal to six. [0004] Each element is completely immersed in an electrolyte consisting of a dilute aqueous solution of sulfuric acid. [0005] The cover...
