The circuit prevents any cell voltage from dropping below a voltage at which degradation of the battery can start. Each of the battery connections are connected with a first polarity across one secondary winding of a transformer through a first diode and connected with a polarity opposite to the first polarity across another secondary winding of the transformer through a second diodes, where, for the cell connections corresponding to each battery except the last in the series, the secondary winding connected through the corresponding first diode is the same as the secondary winding connected through the second diode to the cell connections corresponding to the subsequent battery in the series. The circuit also provides high efficiency voltage balancing during charging of the battery stack."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery management circuit having cell connections for batteries and a plurality of corresponding windings and diodes","description":"A battery management circuit maintains voltage balance during charging and discharging of a multi-cell, series connected battery stack.
