Description

technical field [0001] The invention relates to a storage battery intelligent detection and control device and a detection and control method, belonging to the technical field of detection and control and adjustment devices. Background technique [0002] At present, for the detection and control of the acid solution density, temperature, and liquid level of lead-acid batteries, the corresponding device structure is complex, and cannot be continuously performed online, let alone online calibration, and there are still certain stability and reliability issues. For example, the detection and control methods and corresponding devices of the acid solution density of lead-acid batteries in the prior art usually adopt methods such as the measuring cylinder method, the oscillating tube method, and the differential pressure method and their devices. Among them, the graduated cylinder method and the vibrating tube method are difficult to achieve online continuous measurement of densit...
