Description
technical field [0001] The invention relates to an intelligent controller, in particular to an intelligent controller for a railway locomotive auxiliary generator. Background technique [0002] Valve-regulated lead-acid batteries have the characteristics of less maintenance, less acid pollution, high power density, and long service life, and have been widely used in railway locomotives. [0003] Although valve-regulated lead-acid batteries still belong to the lead-acid battery system, due to the adoption of oxygen cycle technology and lean liquid technology, the requirements for charging and discharging technology and equipment are completely different from those of rich liquid lead batteries. [0004] For liquid-rich lead-acid batteries, when the charging current is equal to or less than the acceptable charging current of the battery, all the charging current is used for charging electrochemical reactions. When the charging current is greater than the acceptable charging c...
