Abstract
An equalizer circuit provides both passive and active charge transfer between cells in a battery pack to improve charge and discharge efficiency. The equalizer circuit is a bilevel circuit that uses both resistive equalizers and switching equalizers to balance cell charge. The cells may be grouped into size limited sections which are balanced by resistive equalizers. The sections are balanced by switching equalizers to promote increased pack discharge capacity.
