Abstract
A battery charging device which charges a plurality of batteries includes a charging part which supplies a charging current, and a control part which controls the charging part so that the batteries are serially charged one by one and a supplemental charge to the batteries is then performed in parallel. The control part calculates a charged capacity for a first one of the batteries and thus determines a timing in which serial charge is switched to a second one of the batteries on the basis of the charged capacity.
