Assembled battery charging method, charging control circuit, and power supply system

摘要

A method for charging an assembled battery including series circuits connected in parallel, each of the series circuits including series-connected lead storage batteries, using a single charger is provided. The method includes: a first step of obtaining a first index value, corresponding to a resistance value of a first series circuit with a correlative relationship, the first series circuit having a lowest resistance value; a second step of obtaining a second index value corresponding to a resistance value of a second series circuit with a correlative relationship, the second series circuit having a highest resistance value; a third step of performing normal charging, in which the assembled battery is charged with a first amount of charge corresponding to the first index value; and a fourth step of performing refresh charging, in which the assembled battery is charged with a second amount of charge corresponding to the second index value.

1. An assembled battery charging method for charging an assembled battery using a single charger, the assembled battery including series circuits, each of the series circuits including one or more lead storage batteries connected in series, the series circuits being connected in parallel, the method comprising:
a first step of obtaining a first index value, which is an index value corresponding to a resistance value of a first series circuit with a correlative relationship, the first series circuit having a lowest resistance value among the series circuits; a second step of obtaining a second index value, which is an index value corresponding to a resistance value of a second series circuit with a correlative relationship, the second series circuit having a highest resistance value among the series circuits, the first series circuit and the second series circuit being connected in parallel; a third step of performing normal charging, in which the assembled battery is charged with a first amount of charge corresponding to the first index value; and a fourth step of performing refresh charging, in which the assembled battery is charged with a second amount of charge corresponding to the second index value, in succession to the third step.
