Ibhethri le-HV vs. Ibhethri le-LV: Iyiphi Efanele Isistimu Yakho Yamandla?

Ibhethri le-HV vs. Ibhethri le-LV: Iyiphi Efanele Isistimu Yakho Yamandla? Ibhethri ye-lithium idlala indima ebalulekile kubuchwepheshe besimanje, inika amandla yonke into kusukela kuma-smartphones kuya ezinhlelweni zamandla elanga. Uma kukhulunywa ngamabhethri elanga e-lithium, ngokuvamile ahlukaniswa ngezinhlobo ezimbili:high voltage battery(Ibhethri le-HV) kanyeibhethri ye-voltage ephansi (Ibhethri le-LV). Kubasebenzisi abanezinsimbi ezidinga amandla angu-400V noma angu-48V, ukuqonda umehluko phakathi kwebhethri le-HV ne-LV kungaba nomthelela omkhulu ekukhetheni kwesistimu yabo yamandla.

Ukuqonda izinzuzo nemikhawulo yohlobo lwebhethri ngalunye kubalulekile. Nakuba izinhlelo zamandla kagesi aphezulu zingase zibe yingozi yokulimala kwesekethe, amasistimu kagesi aphansi angase athinte ukusebenza kukonke. Ukubona lo mehluko kusiza ukunikeza ukuqonda okucacile kwezimiso zabo zokusebenza kanye nezimo ezisetshenziswa kakhulu.

Ibhethri ye-Kamada Power High Voltage

Iyini i-Voltage?

I-Voltage, ikalwa ngama-volts (V), imele umehluko ongaba khona kagesi phakathi kwamaphoyinti amabili kusekethe. Kufana nokucindezela kwamanzi epayipini: ishayela ukugeleza kwamandla kagesi nge-conductor, kufana nokuthi amanzi ageleza ngepayipi.

Amandla kagesi aphezulu kusekethe aphusha amashaji kagesi ngamandla, okuvumela ukudluliswa kwamandla okusebenzayo. Lokhu kubaluleke kakhulu ezinhlelweni zebhethri, lapho amazinga ahlukene kagesi angaba nomthelela omkhulu ekusebenzeni.

Liyini Ibhethri le-HV?

Ibhethri le-HV, noma ibhethri le-voltage ephezulu, lisebenza kumazinga kagesi ngokuvamile asukela ku-100V kuya ku-600V noma ngaphezulu. Lawa mabhethri adizayinelwe izinhlelo zokusebenza ezidinga amandla kagesi aphezulu, esiza ukunciphisa amazinga amanje futhi anciphise ukulahleka kwamandla phakathi nemijikelezo yokushaja nokukhipha. Lokhu kubangela uhlelo lokugcina amandla olusebenza kahle kakhulu futhi olusabelayo, oluzuzisa kakhulu izinhlelo zokusebenza ezinkulu.

I-Pro Insight: Izimoto zikagesi zesimanje (EVs) zivame ukusebenzisa amasistimu ebhethri e-HV anama-voltage asukela ku-400V kuya ku-800V, avumela ukusheshisa okusheshayo kanye nebanga lokushayela elinwetshiwe.

Liyini Ibhethri le-LV?

Ibhethri le-LV, noma ibhethri le-voltage ephansi, ngokuvamile lisebenza kumazinga kagesi ukusuka ku-2V ukuya ku-48V. Lawa mabhethri abonakala ngogesi wawo ophansi, okuwenza afanelekele izinhlelo zokusebenza ezincane ezifana ne-elekthronikhi ephathekayo, amasistimu elanga amancane, kanye nezinsiza zikagesi ezisizayo.

Isibonelo: Ibhethri elijwayelekile elingu-12V le-lead-acid elisetshenziswa ezimotweni ezivamile zenjini evuthayo yangaphakathi ibhethri ye-LV yakudala, enikeza amandla kumotho eyisiqalisi kanye nezinsiza zikagesi.

Ukukhetha Phakathi kwebhethri le-HV ne-LV kuhlelo lwakho lokusebenza

Ukuhlaziya Okusekelwe Kwisimo:

• Izindawo zokuhlala zeSolar Systems: Ngokusethwa kwezindawo zokuhlala ezincane zelanga, ibhethri le-LV lingakhethwa ngenxa yokuphepha nokubalula kwalo. Ekufakeni okukhulu, nokho, ibhethri le-HV livamise ukusebenza kahle futhi lingabizi ngokuhamba kwesikhathi.
• Isitoreji Samandla Ezentengiso: Ekusetheni ezentengiso, ikakhulukazi lezo ezibandakanya isitoreji samandla esikali segridi, amabhethri e-HV ngokuvamile ayinketho engcono ngenxa yekhono lawo lokuphatha amandla amakhulu ngempumelelo.
• Izimoto zikagesi: Amabhethri e-HV abalulekile kuma-EV, anika amandla ukushaja okusheshayo, amabanga okushayela amade, nokusebenza okungcono uma kuqhathaniswa namabhethri e-LV, okungenzeka angahlangabezani nezidingo zamandla zama-EV anamuhla.

I-Decision Matrix: Ibhethri Lamandla Kagesi Ephezulu vs. Ibhethri Lamandla Aphansi

Umehluko Phakathi Kwamabhethri e-LV ne-HV

Amandla Okukhipha Amandla

Amabhethri e-HV ngokuvamile ahlinzeka ngokukhipha amandla aphezulu uma kuqhathaniswa namabhethri e-LV. Lokhu kungenxa yobudlelwano phakathi kwamandla (P), i-voltage (V), kanye neyamanje (I), njengoba kuchazwe yi-equation P = VI.

Isibonelo: Ngokukhishwa kwamandla okungu-10kW, isistimu yebhethri engu-400V HV idinga imanje engu-25A (P = 10,000W / 400V), kanti isistimu ye-48V LV idinga cishe u-208A (P = 10,000W / 48V).
