Battery pack balancing control system and control method on basis of dynamic balance point

摘要: The invention discloses a battery pack balancing control system and method on the basis of dynamic balance point. comprises pack, voltage sampling circuit, main circuit circuit. is used for comparing value each single respectively regulating frequencies power switch tubes corresponding to batteries controlling track frequency in state when difference different exceeds preset threshold value, wherein energy released by adsorbed switching period are equal; tube state. According invention, all can almost simultaneously reach balance, speed efficiency improved, overcharge over-discharge damage caused inconsistency prevented, service life prolonged.
