Abstract

The invention provides a vacuum automatic charging system of a silver-zinc secondary battery electrolyte and a method thereof. The system comprises a cup value module, a transverse stretching module, a mobile servo mechanism, a liquid charge head, a liquid charge pump, a vacuum pump, an air compressor, and a liquid charge needle, wherein the cup value module is connected to the liquid charge head and the liquid charge needle; the liquid charge pump pumps an electrolyte stored in a barrel into the liquid charge needle, and pumps the electrolyte into a liquid storage cylinder; the vacuum pump vacuumizes the whole liquid inlet system including a battery to maintain a liquid inlet process to be in a subatmospheric pressure state or a vacuum state; the air compressor provides pressure for the cup valve module, thus facilitating rapid flowing of the electrolyte; the transverse stretching module controls transverse displacement of the liquid charge needle; the mobile servo mechanism controls vertical movement of the liquid charge needle; and the liquid charge head is connected to a single battery through screw threads. During charging, a vacuumizing automatic charging system is designed according to electrolyte charging characteristics of the silver-zinc secondary battery, and the charging amount is accurately controlled by a digitization manner, so that charging precision is improved. Connecting terminals are in one-to-one correspondence, so that charge missing is effectively prevented, and the charging speed is high.

Description

technical field [0001] The invention relates to a zinc-silver storage battery electrolyte vacuum automatic filling system and a filling method thereof. The invention can avoid manual filling errors, and also improves filling accuracy, which is beneficial to improving the consistency of each single battery and enhancing reliability. Background technique [0002] Zinc-silver battery cells are basically composed of positive poles, negative poles, diaphragms, casings, and electrolytes, and each single cell is connected in series / parallel to form a battery pack. Zinc-silver batteries are generally stored in a dry state, and the electrolyte is filled only when in use. At present, the method of manually filling the electrolyte is mostly used, that is, using a syringe to fill the electrolyte. The method of manually filling the electrolyte has the advantage of simple operation, but it is prone to errors (missing to add cells), and the accuracy is difficult to guarantee, which may aff...
