Mabhanga emagetsi enhare anochengeta sei simba remagetsi?

Mhedzisiro yemabhangi emagetsi enhare iti lithium-ion kana kuti lithium polymer bhatiri (inodarika 60% yemutengo). Kana ichichaja, magetsi ekunze (akadai sechaja yenharembozha) anoisa 5V DC kuburikidza neMicro-USB kana Type-C interface, uye PCB control board inoshandura simba remagetsi kuita kemikari simba rekuchengetedza:

1. Nhanho yekuchaja: Ikozvino yekupinza inodzorwa neIC chip, uye bhatiri inopihwa neiyo inogara iripo (yakadai se1A). Kana iyo voltage yasvika 4.2V, inochinja kune inogara voltage mode kudzivirira kuwandisa.

2. Kuchengetedzwa kwemagetsi emagetsi: Lithium ions inofamba pakati pe electrode yakanaka (lithium cobalt oxide, nezvimwewo) uye electrode yakaipa (graphite) kuti iwane simba rekuchengetedza. Iro zita remagetsi ebhatiri rimwe sero 3.7V, uye huwandu hwacho hunowanzo 5000mAh-20000mAh (data source: IEC 61960 standard).
