Ongorora: Iyo yazvino dhizaini inoshanduka zvichienderana nezvaunoita neRaspberry Pi yako. Kana iwe uchitamba mavhidhiyo kana kushandisa GPIO mapini, bhatiri rako rinopera nekukurumidza. Kana Pi yako ikagara isina basa kana kushandisa hope dzakadzama, inoshandisa simba shoma.
Semuenzaniso Masvomhu
Iwe unogona kufungidzira kuti Raspberry Pi yako yakareba sei gadziriro yesimba rebhatiri inozogara nekushandisa fomula iri nyore. Izvi zvinokubatsira kuronga purojekiti yako uye kudzivirira kupera simba.
To kuverenga hupenyu hwebhatiri, shandisa:
Hupenyu (muma cycles) = (Kugona x 100) / (Discharge rate x Hudzamu hwekubuda)
Kugona kuri muamp-maawa (Ah)
Chiyero chekuburitsa chiri mu amperes (A)
Hudzamu hwekuburitsa izana rebhatiri rinoshandiswa risati rachaja
Ngatitii unoshandisa 5000mAh (5Ah) lithium bhatiri uye Raspberry Pi 4 B yako inodhirowa 1A iri pasi pemutoro. Kana ukashandisa 80% yebhatiri usati wachajazve, kuverenga kwako kunoratidzika seizvi:
Life = (5 x 100) / (1 x 80) = 500 / 80 = 6.25 cycles
Nekuchaja kamwe chete, unogona kufungidzira nguva yekumhanya seizvi:
Nguva yekumhanya (maawa) = Battery simba (Ah) / Yazvino dhirowa (A)
Muenzaniso: 5Ah / 1A = maawa mashanu
Zano: Kana purojekiti yako ikashandisa kurara kwakanyanya kana kugara isina chayakaita, unogona kuwana mamwe maawa kubva kubhatiri rako. Kutanga kunoshandisa simba rakawanda, saka kazhinji reboots inogona kupfupisa hupenyu hwebhatiri.
Unogona kushandisa zviverengero izvi kusarudza bhatiri rakakodzera reRaspberry Pi bhatiri simba reprojekiti.
