摘要： The present invention relates to a pulse charging method and charging system for use with non-aqueous secondary batteries, employing a pulse charge controlling method all the way from the start to the end of charging. This pulse charging method has an on-duty ratio of pulses in a next specified charge period reduced when an average battery voltage has exceeded a charge control voltage during a specified charge period, has an on-duty ratio of pulses in a next specified charge period increased when the average battery voltage has not exceeded the charge control voltage and has the pulse charging ended when an on-duty ratio of pulses has reached a specified value. The pulse charging system comprises an on-duty ratio reducing means for having an on-duty ratio of pulses reduced, an on-duty ratio increasing means for having an on-duty ratio increased and a means for determining pulse charge ending for having the pulse charging ended when an on-duty ratio of pulses has reached a specified value. Thus, it has become possible to provide a charging system that can be built in a battery pack, is inexpensive, free of heat generation and, in addition, allows the charging time to be reduced.
