摘　　要：针对过充电或过放电现象对蓄电池本身特性产生影响、降低使用寿命的问题,以蓄电池组为研究对象,对蓄电池放电深度和循环寿命作分析,设计出蓄电池的充放电智能控制系统。使用数据采集模块对蓄电池组内部电压、电流、内阻和温度进行监测,保证了蓄电池充放电过程的安全。试验结果表明,系统对蓄电池内部采集到的数据精度更高,充放电控制电路的反应时间更小,系统的稳定性更强。所研究系统能够对蓄电池充放电过程进行有效地监测控制,将电压电流控制在一定范围内,防止出现过充电、过放电的情况,为现有蓄电池的充放电控制方法提供了新的思路。Aiming at the problem that overcharge or over-discharge affects the battery’s own characteristics and reduce the service life, the battery packs were taken as the research objects, the depth of discharge and cycle life of the batteries were analyzed, and a battery charge and discharge intelligent control system was designed. The data acquisition module was used to monitor the internal voltage, current, internal resistance and temperature of the battery packs to ensure the safety of the battery charging and discharging process. The test data shows that the system has higher accuracy on the data collected inside the battery, shorter reaction time of charge and discharge control circuit, and stronger stability of system. The system can effectively monitor and control the battery charge and discharge process, control the voltage and current within a certain range, prevent overcharge and over-discharge, and provide a new idea for the existing battery charge and discharge control methods.
