Problems solved by technology

[0003] The biggest problem encountered by the storage battery in practical application is that its service life is far short of the design service life. The storage battery with a design service life of 10 to 15 years is mostly damaged in 3 to 5 years in actual use, and some are even less than 1 year. It will fail within one year, which not only affects the reliability of locomotive operation, but also causes large economic losses
According to the information feedback of HXD1B and HXD1C locomotives in the section, during the operation of locomotives in my country, battery bulges and serious power shortages often occur, which makes the advantages of valve-regulated lead-acid batteries unable to be fully utilized and reduces their service life.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a DSP-based valve-controlled lead-acid battery charging system. Background technique [0002] Valve-regulated lead-acid batteries have been widely used due to their advantages of good sealing, no leakage, no pollution, rechargeable, low cost, and safe use. my country's railway harmonious high-power locomotive batteries mostly use this kind of rechargeable battery. The battery is an essential power source when the locomotive is started, and it is also a backup power source when the locomotive is running. Reducing the failure rate of the battery is of great significance to ensure the normal operation of the locomotive. [0003] The biggest problem encountered by the storage battery in practical application is that its service life is far short of the design service life. The storage battery with a design service life of 10 to 15 years is mostly damaged in 3 to 5 years ...
