一種充電方法,適用於對彼此串聯的一第一充電電池及一第二充電電池進行充電,該方法首先令一充電電路偵測該等充電電池的電壓值,若該等充電電池的電壓值總和小於一第一預設電壓值,充電電路產生一定電流脈衝訊號對該等充電電池進行充電,若該等充電電池的電壓值總和大於該第一預設電壓值,充電電路產生一定電壓脈衝訊號對該等充電電池進行充電,直到若該等充電電池的電壓值總和大於一第二預設電壓值;接著充電電路產生該定電壓脈衝訊號先後對第一、第二充電電池充電,直到第一、第二充電電池的電壓值分別大於一第三預設電壓值。 A series charge equalizer with pulse charging and digital monitoring is presented, which is mainly built up by a flyback converter controlled by a power-factor-corrected (PFC) control integrated circuit (IC) named L6562. Above all, the output capacitor is removed from this converter to obtain the pulsating output current, so as to achieve pulse charging.Furthermore, two 12V lead-acid batteries connected in series are equalizedly charged, by the flyback converter along with several auxiliary components. There are three charging functions in the proposed charge equalizer, containing series constant voltage charging, series constant current charging, and constant voltage charging for a single battery at near the full charging.
