Ngokuthuthuka okusheshayo kokugcinwa kwamandla avuselelekayo, abakhiqizi abangenakubalwa nabahlinzeki bempahlaAmabhethri e-LiFePO4ziye zavela eChina. Nokho, izinga lalaba bakhiqizi lihluka kakhulu. Ngakho-ke, ungaqinisekisa kanjani ukuthi ibhethri lasekhaya olithengayo lenziwa ngamaseli e-LiFePO4 eBanga A?
E-China, amaseli e-LiFePO4 ahlukaniswe abe amabanga amahlanu:
- IBANGA A+
– IBANGA A-
– IBANGA B
– IBANGA C
- SEYIKE YASETSHENZISWA
Kokubili IBANGA A+ kanye ne-Grade A- kubhekwa njengamaseli e-LiFePO4 eBanga A. Kodwa-ke, i-GRADE A- ibonisa ukusebenza okuphansi kancane mayelana nomthamo ophelele, ukungaguquguquki kwamaseli, nokumelana kwangaphakathi.
Ungawabona Kanjani Ngokushesha Amaseli e-LiFePO4 eBanga A?
Uma ungumsabalalisi wezisetshenziswa zelanga noma isifaki esisebenza nomnikezeli omusha webhethri, unganquma kanjani ngokushesha ukuthi umphakeli ukuhlinzeka ngamaseli e-LiFePO4 Ebanga A? Landela lezi zinyathelo, futhi uzothola ngokushesha leli khono elibalulekile.
Isinyathelo 1: Hlola Ukuminyana Kwamandla Amaseli
Ake siqale ngokuqhathanisa ukuminyana kwamandla kwamaseli angu-3.2V 100Ah LiFePO4 avela kubakhiqizi bebhethri abaphezulu abahlanu abagcina amandla e-China:
| Ibhrendi | Isisindo | Ukucaciswa | Amandla | Ukuminyana kwamandla |
| EVE | 1.98kg | 3.2V 100Ah | 320Wh | 161Wh/kg |
| REPT | 2.05kg | 3.2V 100Ah | 320Wh | 150Wh/kg |
| I-CATL | 2.27kg | 3.2V 100Ah | 320Wh | 140Wh/kg |
| BYD | 1.96kg | 3.2V 100Ah | 320Wh | 163Wh/kg |
Amacebiso: Ukuminyana kwamandla = Amandla / Isisindo
Kusukela kule datha, singaphetha ngokuthi Amaseli e-LiFePO4 eBanga A avela kubakhiqizi abahamba phambili anomthamo wamandla okungenani ongu-140Wh/kg. Ngokuvamile, ibhethri lasekhaya elingu-5kWh lidinga amaseli anjalo angu-16, nekesi yebhethri enesisindo esingama-15-20kg. Ngakho, isisindo esiphelele singaba:
| Ibhrendi | Isisindo Seseli | Isisindo Sebhokisi | Ukucaciswa | Amandla | Ukuminyana kwamandla |
| EVE | 31.68kg | 20kg | 51.2V 100Ah | 5120Wh | 99.07Wh/kg |
| REPT | 32.8kg | 20kg | 51.2V 100Ah | 5120Wh | 96.96Wh/kg |
| I-CATL | 36.32kg | 20kg | 51.2V 100Ah | 5120Wh | 90.90Wh/kg |
| BYD | 31.36kg | 20kg | 51.2V 100Ah | 5120Wh | 99.68Wh/kg |
Amacebiso: Ukuminyana kwamandla = Amandla / (Isisindo seseli + Isisindo sebhokisi)
Ngamanye amazwi, a5kWh ibhethri lasekhayakusetshenziswa Amaseli e-LiFePO4 eBanga A kufanele abe nokuminyana kwamandla okungenani okungu-90.90Wh/kg. Ngokucaciswa kwemodeli ye-BSLBATT ye-Li-PRO 5120, ukuminyana kwamandla ngu-101.79Wh/kg, okuhambisana eduze nedatha yamaseli e-EVE nawe-REPT.
Isinyathelo sesi-2: Linganisa Isisindo Samaseli
Ngokusekelwe kudatha evela kubakhiqizi abane abahamba phambili, isisindo seseli eyodwa ye-3.2V 100Ah Grade A LiFePO4 silinganiselwa ku-2kg. Kusukela kulokhu, singabala:
- Ibhethri le-16S1P 51.2V 100Ah lizoba nesisindo esingu-32kg, kanye nesisindo sekheshi esingaba ngu-20kg, ngesisindo esiphelele esingu-52kg.
- Ibhethri le-16S2P 51.2V 200Ah lizoba nesisindo esingu-64kg, kanye nesisindo sekheshi esingaba ngu-30kg, ngesisindo esiphelele esingu-94kg.
(Abakhiqizi abaningi manje basebenzisa ngokuqondile amaseli angu-3.2V 200Ah kumabhethri angu-51.2V 200Ah, njenge-BSLBATT'sI-Li-PRO 10240. Umgomo wokubala uhlala unjalo.)
Ngakho-ke, lapho ubuyekeza izingcaphuno, qaphela kakhulu isisindo sebhethri esinikezwe umenzi. Uma ibhethri lisinda ngokweqile, amaseli asetshenzisiwe cishe awekhwalithi engabazekayo futhi awawona amaseli e-LiFePO4 eBanga A.
Ngokukhiqizwa okuningi kwezimoto zikagesi, amabhethri e-EV amaningi asethathe umhlalaphansi aphinde asetshenziselwa ukugcinwa kwamandla. Lawa maseli ngokuvamile adlule izinkulungwane zemijikelezo yokushaja, enciphisa kakhulu impilo yomjikelezo kanye nesimo sezempilo (SOH) samaseli e-LiFePO4, okungenzeka ashiye kuphela u-70% noma ngaphansi kwamandla awo okuqala. Uma amaseli amasekeni esetshenziswa ukwenza amabhethri asekhaya, azuza okufanayo10kw umthamo ungadinga amaseli engeziwe, okuholela ebhethri elisindayo.
Ngokulandela lezi zinyathelo ezimbili, uzokwazi ukuba uchwepheshe webhethri okwazi ukuhlonza ngokuzethemba ukuthi ibhethri lakho lenziwe ngamaseli e-LiFePO4 EBanga A, okwenza le ndlela isebenziseke ikakhulukazi kubasabalalisi bemishini yelanga noma kumakhasimende aphakathi nemakethe.
Kunjalo, uma uchwepheshe emkhakheni wamandla avuselelekayo onokufinyelela okokusebenza kokuhlola ibhethri, ungaphinda uhlole eminye imingcele yobuchwepheshe njengomthamo, ukumelana kwangaphakathi, izinga lokuzikhipha, kanye nokutholwa kwamandla ukuze unqume ngokunembe kakhudlwana ibanga leseli.
Amathiphu Okugcina
Njengoba imakethe yokugcina amandla iqhubeka nokukhula, imikhiqizo eminingi nabakhiqizi bazovela. Lapho ukhetha umhlinzeki, hlala uqaphile kulabo abanikeza amanani aphansi ngokusolisayo noma izinkampani ezisanda kusungulwa, njengoba zingase zibe yingozi ebhizinisini lakho. Abanye abaphakeli bangase basebenzise namaseli e-LiFePO4 Ebanga A ukukhiqiza amabhethri asekhaya kodwa benze ihaba umthamo wangempela. Isibonelo, ibhethri elenziwe ngamaseli angu-3.2V 280Ah akha ibhethri elingu-51.2V 280Ah lizoba nomthamo ongu-14.3kWh, kodwa umphakeli angase alikhangise njengo-15kWh ngenxa yokuthi amandla aseduze. Lokhu kungase kukudukise ucabange ukuthi uthola ibhethri elingu-15kWh ngentengo ephansi, kanti empeleni ingu-14.3kWh kuphela.
Ukukhetha umphakeli webhethri lasekhaya othembekile nochwepheshe kuwumsebenzi oyinselele. Njengoba kunezinketho eziningi ezitholakalayo, kulula ukukhungatheka. Kungakho sincoma ukuthi ubheke kuI-BSLBATT, umkhiqizi onolwazi olungaphezu kweminyaka engama-20 embonini yebhethri. Nakuba amanani ethu engase angabi ngaphansi kakhulu, ikhwalithi yomkhiqizo wethu kanye nesevisi kuqinisekisiwe ukushiya umbono ohlala njalo. Lokhu kusekelwe embonweni wethu womkhiqizo: ukuhlinzeka ngezixazululo zebhethri le-lithium ezingcono kakhulu, yingakho sihlala siphikelela ekusebenziseni amaseli e-LiFePO4 eBanga A.
