| Zusammenfassung: | The invention discloses a storage battery system, a charging system and a charging method. The storage battery system comprises a storage battery; a step-down chopper circuit which comprises a chopper module which is used for carrying out step-down processing on the input voltage of the storage battery system and outputting the voltage after step-down to the storage battery as charging voltage; a voltage detection module which is used for detecting the output voltage of the chopping module; a current detection module which is used for detecting the output current of the chopping module; a driving protection module which is used for providing a switch driving signal for the switch tube; a controller which is used for adjusting the pulse duty ratio of a switching tube in the chopper module when the input voltage of the storage battery system is larger than the preset charging voltage or the input current of the storage battery system is larger than the preset charging current, so that the charging voltage outpu |
