对光伏系统、UPS和电动汽车中的电池组的调查表明，由于单个电池的不同特性而导致的个体化会导致整个电池的过早失效。单细胞监测无法解决这个问题。本文介绍的新的“充电均衡器”（CHEQ）通过在电池之间传递能量来使所有电池始终处于相同的充电状态。对于不同的应用程序，特别适合的实现这一基本原则。CHEQ的主要优点是：防止单个电池的过度充电和深度放电，延长使用寿命，降低维护成本，提供全部标称容量。<<ETX>>
Investigations of battery banks in photovoltaic systems, UPS and electric vehicles show that individualization of single cells due to different properties leads to premature failures of the whole battery. Single cell monitoring is no way to overcome this problem. The new "charge equalizer" (CHEQ) introduced in this paper keeps all cells in the same state of charge at all times by transferring energy between the cells. For different applications, specially suited implementations of this fundamental principle are shown. The main advantages of the CHEQ will be: protection against overcharging and deep discharging of individual cells, extension of lifetime, decrease of maintenance costs, availability of the full nominal capacity.<<ETX>>
