Uke waqaphela yini ukuthi i-voltage yebhethri ye-lithium yehla ngemva nje kokushajwa ngokugcwele? Lokhu akulona iphutha—ukuziphatha okujwayelekile komzimba okwaziwa ngokuthiukwehla kwamandla kagesi. Ake sithathe isampula yethu yebhethri yeloli engu-8-cell LiFePO₄ (lithium iron phosphate) 24V njengesibonelo ukuze sichaze.
1. Iyini I-Voltage Drop?
Ngokwethiyori, leli bhethri kufanele lifinyelele ku-29.2V uma selishajwe ngokugcwele (3.65V × 8). Nokho, ngemva kokukhipha umthombo wamandla wangaphandle, i-voltage yehla ngokushesha ifike cishe ku-27.2V (cishe i-3.4V ngeseli). Nasi isizathu:
- I-voltage ephezulu ngesikhathi sokushaja ibizwa ngokuthi i-Shaja i-Cutoff Voltage;
- Lapho ukushaja kuyeka, i-polarization yangaphakathi iyanyamalala, futhi i-voltage yehlela ngokwemveloVula i-Circuit Voltage;
- Amaseli e-LiFePO₄ ngokuvamile ashaja kufika ku-3.5–3.6V, kodwa wonaayikwazi ukugcina leli zingaisikhathi eside. Kunalokho, azinza ku-voltage yesikhulumi phakathiI-3.2V kanye ne-3.4V.
Yingakho i-voltage ibonakala "yehla" ngemva nje kokushaja.
2. Ingabe Ukwehla Kwegesi Kuthinta Umthamo?
Abanye abasebenzisi bakhathazeka ngokuthi lokhu kwehla kwamandla kagesi kungase kwehlise umthamo webhethri osebenzisekayo. Empeleni:
- Amabhethri e-lithium ahlakaniphile anezinhlelo zokuphatha ezakhelwe ngaphakathi ezikala ngokunembile futhi zilungise umthamo;
- Izinhlelo zokusebenza ezinikwe amandla i-Bluetooth zivumela abasebenzisi ukuthi baqapheamandla agciniwe wangempela(okungukuthi, amandla okukhipha asebenzisekayo), futhi ulinganise kabusha i-SOC (Isimo Sokukhokhiswa) ngemva kokushajwa ngakunye okuphelele;
- Ngakho-ke,Ukwehla kwamandla kagesi akuholeli ekwehliseni umthamo osebenzisekayo.
3. Kufanele Uqaphele Nini Uma Ukwehla Kwe-Voltage
Nakuba ukwehla kwamandla kagesi kuyinto evamile, kungenziwa ihaba ngaphansi kwezimo ezithile:
- Izinga Lokushisa Impact: Ukushaja emazingeni okushisa aphezulu noma aphansi kungabangela ukwehla kwamandla kagesi ngokushesha;
- Ukuguga Kweseli: Ukwenyuka kokumelana kwangaphakathi noma amazinga aphezulu okuzikhulula nakho kungabangela ukwehla kwamandla kagesi ngokushesha;
- Ngakho-ke abasebenzisi kufanele balandele izinqubo zokusetshenziswa ezifanele futhi baqaphe impilo yebhethri njalo.
Isiphetho
Ukwehla kwamandla kagesi kuyinto evamile kumabhethri e-lithium, ikakhulukazi ezinhlotsheni ze-LiFePO₄. Ngokuphathwa kwebhethri okuthuthukisiwe namathuluzi okuqapha ahlakaniphile, singaqinisekisa kokubili ukunemba kokufundwa kwamandla kanye nempilo yesikhathi eside nokuphepha kwebhethri.
