【 摘 要 】

By real-time acquisition information of lithium titanate battery packs and single battery in the auxiliary battery system of rail vehicles, we have extracted the operating condition of the train auxiliary battery system, and emphatically established the battery float charging test under the influence of temperature, voltage and other factors. Then have analyzed the aging state information of the battery. Combined with the thermodynamic and dynamics characteristics of the power battery, established the law of change of the battery characteristic parameter with the battery float charge, and determined the recession mechanism of battery
