Description
Technical field
The utility model relates to the storage battery field, and particularly a kind of simulated battery is cell negative terminal sealed reaction efficient gas collecting apparatus and method of testing under actual working state.
Background technology
As everyone knows, though the VRLA battery has adopted the oxygen cycle complex technique, battery still can not be realized sealing fully, separates out because battery still has gas in use and charging process.What (gas is height of chemical combination efficient again) of battery bubbing are weighed through this index of sealed reaction efficient.The height of the combined-circulation efficient of oxygen is to influence a battery important factors in useful life.
The factor that influences gas chemical combination efficient is a lot, driving valve and closing the setting of valve pressure, electrolyte saturation etc. such as the performance of utmost point crowd's in the battery compression and structure, dividing plate, unidirectional valve.
The test of cell sealing reaction efficiency is normally accomplished on whole battery, and what reflect is whole battery what of bubbing in experimentation, and the real gas that can't obtain single lattice battery is like this separated out situation information.
Battery is to connect in groups to use on electric bicycle.In battery testing and use in groups, always find to have a single battery phenomenon that only falls behind to take place, had a strong impact on the life-span that recycles that becomes Battery pack like this.In order to solve this difficult problem, the research staff has done a large amount of analysis and research work.The test of cell negative terminal sealed reaction efficient can provide the partial information of cell negative terminal performance, and this is to single cell negative terminal and become consistency analysis of Influential Factors of Battery pack to provide greatly to help.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of directly perceived and cell negative terminal sealed reaction efficient gas collecting apparatus that six single lattice of battery can use same device to test simultaneously respectively.
The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of cell negative terminal sealed reaction efficient gas collecting apparatus; Comprise gas collection housing, tank, graduated cylinder and graduated cylinder support; The battery liquid-filling hole that is tightly connected, said gas collection housing lower end; Gas collection housing upper end is provided with water inlet and exhaust outlet, and exhaust outlet connects a glass bend pipe one end through a plastic flexible pipe, and the glass bend pipe other end stretches in the graduated cylinder; Said graduated cylinder opening is inverted down and is hung on the graduated cylinder support, and the graduated cylinder openend places tank,
Further improvement as the utility model; Be provided with a up and down compressing tablet in the said gas collection housing; The compressing tablet middle upper part connects one and stretches out the knob that compresses of gas collection housing, and is provided with some air-vents above the excessive acid tank position around the corresponding battery liquid-filling of the said compressing tablet hole.
As the further improvement of the utility model, said water inlet pipe is provided with the valve that a control is closed.
As the further improvement of the utility model, the height of said gas collection housing is 20mm.
As the further improvement of the utility model, said compressing tablet is a round tablet, and the diameter of compressing tablet is greater than liquid injection hole diameter 2mm at least.
The beneficial effect of the utility model is: the gas collecting apparatus of the utility model can carry out the test of sealed reaction efficient to single battery; The information of single lattice battery ability can be provided; Consistency analysis of Influential Factors to forming battery can provide bigger help; And this device is simple in structure, easy to operate, and testing efficiency is high.
