Abstract

The invention discloses a charging-free acid extraction apparatus and acid extraction method for an AGM storage battery. The AGM storage battery comprises a battery case, a battery cover, and AGM partition plates, a negative electrode plate, a positive electrode plate and corresponding busbars placed in the battery case; the acid extraction apparatus comprises an acid extraction pipe and an acid extraction cap; the acid extraction pipe adopts a variable diameter structure and is externally connected with a negative pressure source; the acid extraction cap adopts a thin-wall groove-shaped structure with an open one end; the acid extraction pipe is perpendicularly arranged on the groove-shaped bottom surface of the acid extraction cap; the groove opening end plane of the acid extraction capis covered with a sealing rubber cushion; and a pressure release opening is formed in the side surface of the acid extraction cap. By adoption of a normal pressure-negative pressure alternately changed voltage transformation acid extraction process, the free acid in the battery case can be fully extracted, and 4-10% of gap can be reserved in the AGM partition plates through control, so that the requirement of oxygen generation and compounding in the interior can be satisfied; and meanwhile, the same result can be achieved without consuming electric energy, and the acid extraction time is alsoshorter.

Description

technical field [0001] The invention relates to an acid pumping process of a storage battery, in particular to a charge-free acid pumping device and an acid pumping method for an AGM battery that does not consume electric energy and has a short acid pumping time. Background technique [0002] For sealed lead-acid batteries made of AGM separators, the electrolyte in the AGM separators is in an unsaturated state after the finished product, leaving about 4% to 10% of the gaps, and the oxygen generated by the positive electrode will pass through during charging. The gap of AGM reaches the negative electrode, recombines with the hydrogen generated by the negative electrode to form water, and returns to the electrolyte, which prevents the battery from failing prematurely due to water loss. [0003] Now this kind of battery is manufactured using the internal chemical formation method. After the chemical formation is completed, in order to leave a gap of 4% to 10% in the AGM separat...
