I-Chemistry Oyikhethayo Ishintsha i-BMS Oyidingayo
Kwiphakethe lokugcina amandla, ikhemistri yamaseli inquma okungaphezu kobuningi bamandla kanye nezindleko - ibeka iwindi le-voltage, inani lamaseli alandelanayo, kanye nemikhawulo yokuvikela okumele isetshenziswe uhlelo lokuphatha ibhethri (i-BMS). Lo mhlahlandlela uqhathanisa amakhemikhali amane asetshenziswa ekugcineni - i-LiFePO4 (LFP), i-NMC (i-nickel manganese cobalt), i-LTO (i-lithium titanate), kanye ne-sodium-ion - nokuthi kusho ukuthini ngayinye uma ukhetha i-BMS. Ukuze uthole izinyathelo eziphelele zokukhetha i-BMS, qala kusukela ku-Umhlahlandlela wokukhetha i-BMS.
Amakhemikhali Amane Ngokubuka Nje
Ithebula libonisaummeleliamanani — izibalo zangempela ziyahlukahluka kuye ngomkhiqizi kanye neseli, ngakho-ke qinisekisa ishidi ledatha leseli lakho.
| Ikhemistri | Iseli elijwayelekile V | Ukunqanyulwa kokushaja/ukukhipha | Impilo yomjikelezo ohlobene | Isici esiyinhloko |
|---|---|---|---|---|
| I-LiFePO4 (LFP) | ~3.2 V | ~3.65 V / ~2.5 V | Okuphezulu (~3,000–6,000) | Isitoreji esiphephile, esihlala isikhathi eside, esivamile |
| I-NMC (i-Li-ion) | ~3.6–3.7 V | ~4.2 V / ~2.5–3.0 V | Okumaphakathi (~1,000–2,000) | Ukuminyana kwamandla aphezulu, okuncane |
| I-LTO | ~2.3 V | ~2.8 V / ~1.5 V | Kuphezulu kakhulu (kufika ku-~20,000–30,000) | Umjikelezo/izinga lokushisa elidlulele, ukushaja okusheshayo; amandla aphansi |
| I-Sodium-ion | ~2.9–3.1 V | ~3.45–4.0 V / ~1.5 V | Okuvelayo (okuncike kuseli) | Ukusebenza okuhle kwezinga lokushisa eliphansi; ukuthuthukiswa kokuhlinzekwa |
Amanani amele ukuqhathanisa kuphela; qinisekisa ishidi ledatha lomhlinzeki weseli lakho ukuze uthole imikhawulo yangempela.
Indlela Yokucabanga Ngokukhetha
I-LiFePO4— okuzenzakalelayo kwezindawo eziningi zokugcina izinto zasekhaya nezebhizinisi.
Ibhalansi eqinile yokuphepha, impilo yomjikelezo omude, kanye nezindleko. Uma ungenaso isizathu sokukhetha ngenye indlela, i-LiFePO4 ivame ukuba yindawo yokuqala.
I-NMC— lapho ukuminyana kwamandla kanye nokubumbana kubaluleke kakhulu.
Ubuningi bamandla aphezulu ephaketheni elincane, elilula, ngezindleko zemijikelezo embalwa kanye nokuphathwa kokushisa okuqinile.
I-LTO— impilo yomjikelezo eyeqile, ukushaja okusheshayo, kanye namazinga okushisa abanzi.
Ukukhetha okubalulekile kodwa okuhlala isikhathi eside lapho ubude besikhathi kanye nobubanzi bezinga lokushisa budlula ubuningi bamandla. →Ukukhetha i-BMS ye-LTO.
I-Sodium-ion— inketho entsha yezimo ezibandayo kanye nokunikeza ukuhlukahluka.
Ukuziphatha okuthembisayo kwezinga lokushisa eliphansi kanye nochungechunge oluhlukile lokuhlinzeka, olune-ecosystem ethuthukayo. →Ukukhetha i-BMS ye-sodium-ion.
Okushiwo Yikhemistri Ngayinye Nge-BMS
Kungakhathaliseki ukuthi ukhetha yiphi ikhemistri, i-BMS kumele ilungiselelwe yona:
Imikhawulo yokuvikela.
Imikhawulo ye-over-voltage, i-under-voltage, kanye ne-balancing iyahluka ngokwe-chemistry — isethi ye-BMS ye-chemistry eyodwa izoyivikela kabi enye.
Inani lochungechunge.
Ngenxa yokuthi i-voltage yeseli ejwayelekile iyahluka, inani lamaseli ochungechungeni lwe-voltage yephakethe eliqondiwe liyashintsha — i-LTO idinga amaseli amaningi, i-NMC encane kakhulu, ye-voltage efanayo.
Ukulinganisa kwesimo sezimali.
I-SOC ifundwa kusukela ku-voltage curve yekhemistri; ukusebenzisa i-curve engalungile kubika izinga lokushaja elingalungile.
I-DALY: Umlingani Oyedwa We-BMS Kuzo Zonke Izinkampani Zekhemistri Ezine
I-DALY ikhiqiza izinhlelo zokuphatha amabhethri ze-I-LiFePO4, i-NMC, i-LTO, kanye ne-sodium-ion. Imikhawulo yokuvikela, inani lochungechunge, ukulinganisa isimo seshaja, kanye nokulinganisela kulungiselelwe iseli lakho elithile - ukuze ukwazi ukwenza kube ngokwejwayelekile kumlingani oyedwa we-BMS kuzo zonke izinhlobo zamakhemikhali. Thumela ishidi ledatha leseli lakho kanye nomklamo wephakethe, futhi ithimba lobunjiniyela le-DALY lizoqinisekisa ukucushwa okulungile kwekhemistri oyikhethile.
imibuzo ejwayelekile ukubuzwa
Q1Yimuphi umakhemikhali ongcono kakhulu wokugcina ilanga ekhaya?
I-LiFePO4 iyisinqumo esiyinhloko ngenxa yokulinganisela kwayo ukuphepha, impilo yomjikelezo, kanye nezindleko. I-NMC, i-LTO, kanye ne-sodium-ion zifanela izinto eziza kuqala — ukuqina, ukuhlala isikhathi eside/ukushisa okukhulu, noma isimo sezulu esibandayo futhi zihlinzeka ngokuhlukahluka.
Q2Ingabe i-BMS eyodwa ingaphatha amakhemikhali ahlukene?
I-BMS kumele ilungiselelwe ikhemistri ethile — imikhawulo yayo, inani lochungechunge, kanye nejika le-SOC. Umhlinzeki ofanayo anganikeza i-BMS ye-chemistry ehlukene, kodwa i-BMS yephakethe ngalinye imiselwe amaseli ayo.
Q3Kungani i-chemistry ishintsha inani lamaseli ochungechungeni?
Ikhemistri ngayinye ine-voltage ehlukile yeseli, ngakho-ke ukufinyelela i-voltage yephakethe eliqondiwe kuthatha inani elihlukile lamaseli - isibonelo i-LTO (~2.3V) idinga amaseli amaningi kune-LiFePO4 (~3.2V) ye-voltage efanayo.
Mayelana ne-DALY
I-DALY iklama futhi ikhiqize izinhlelo zokuphatha amabhethri e-lithium zama-OEM, abakhiqizi bamaphakethe, kanye nabahlanganisi, ngebhizinisi lonkeAmazwe nezifunda ezingaphezu kuka-130Ngomthamo wokukhiqiza waminyaka yonke we-Amayunithi ayizigidi ezingu-20, iqembu leOnjiniyela be-R&D abangaphezu kwe-100, futhicishe amalungelo obunikazi ayi-100, I-DALY isekela yonke imikhiqizo ngeIwaranti yamahhala yonyaka owodwakanye nokusekelwa kobuchwepheshe bomhlaba wonke okuphendula ngokushesha.
Angiqiniseki ukuthi iyiphi i-Chemistry — noma iyiphi i-BMS?
Tshela ithimba lobunjiniyela be-DALY isicelo sakho kanye nezinto eziza kuqala, kanye neseli olicabangayo, futhi bazoncoma ukucushwa kwe-BMS ukuze kufane — kunoma iyiphi yamakhemikhali amane.
- Yabelana: ukusetshenziswa kanye nezinto eziza kuqala (ukuphepha, impilo yomjikelezo, ubuningi bamandla, izinga lokushisa eliphansi, izindleko), kanye ne-cell/chemistry oyicabangelayo.
- Faka uma kwaziwa: i-voltage yephakethe eliqondiwe kanye nomthamo, ugesi wamanje, isidingo sokuxhumana, kanye nenani le-oda.
