分布式蓄电池监测系统中电压均衡技术研究

Research of voltage balance technology in distributed battery monitoring system

直流电源在供电系统中发挥着不可替代的作用,蓄电池作为直流系统的后备保障,无疑是最后一道保险。而在实际应用中,蓄电池由于电压不均衡导致容量下降,使用寿命缩短的情况十分常见。针对此种情况,提出了一种电压均衡技术,并设计了电压均衡电路。通过蓄电池组的试验表明,该技术可以很好地改善蓄电池电压均衡状态,为蓄电池智能化监测管理提供一种可行的技术手段。

DC power plays an irreplaceable role in the power supply system, and battery as the backup power is the last line of insurance of DC system. In practical applications, the problems of decresing battery capacity and shortening service life caused by unbalanced situation of battery voltage are common. For such cases, the technique of voltage balance was proposed and the circuit was designed. The actual test results indicate that the technique can improve the situation of voltage balance, providing a feasible way for the battery intelligent monitoring.
