Ukuvula iiMfihlo zokubona iiseli zeLiFePO4 zeBanga A

Ngophuhliso olukhawulezayo lokugcinwa kwamandla avuselelekayo, abavelisi abangenakubalwa kunye nabanikezeli beiibhetri zeLiFePO4ziye zavela eTshayina. Nangona kunjalo, umgangatho waba bavelisi uhluka kakhulu. Ke, ungaqinisekisa njani ukuba ibhetri yekhaya oyithengayo yenziwe ngeeSeli zeLiFePO4 zeBanga A?

E-China, iiseli ze-LiFePO4 zohlulwe ngokwamanqanaba amahlanu:

- IBANGA A+
– IBANGA A-
– IBANGA B
– IBANGA C
- ISEKENI

Omabini IBANGA A+ kunye neBANGA LE-A- athathwa ngokuba ziiSeli zeLiFePO4 zeBanga A. Nangona kunjalo, i-GRADE A- ibonisa ukusebenza okuphantsi kancinci ngokumalunga nomthamo opheleleyo, ukuhambelana kweeseli, kunye nokuchasana kwangaphakathi.

Uzichonga njani ngokukhawuleza iiseli zeLiFePO4 zeBanga A?

Ukuba ungumsasazi wezixhobo zesola okanye umfakeli osebenza nomboneleli omtsha webhetri, unokubona njani ngokukhawuleza ukuba umthengisi uyakubonelela ngeeSeli zeLiFePO4 zeBanga A? Landela la manyathelo, kwaye uya kufumana ngokukhawuleza obu buchule buxabisekileyo.

Inyathelo loku-1: Vavanya ukuNina kwamandla kwiiseli

Masiqale ngokuthelekisa ukuxinana kwamandla e-3.2V 100Ah LiFePO4 iiseli ezivela kwabaphezulu abahlanu abagcina amandla ebhetri abavelisi eTshayina:

Iingcebiso: Ubuninzi bamandla = Umthamo / Ubunzima

Ukusuka kule datha, sinokugqiba ukuba iBanga A LiFePO4 Iiseli ezivela kubavelisi abahamba phambili banobuninzi bamandla ubuncinane be-140Wh / kg. Ngokuqhelekileyo, ibhetri yasekhaya eyi-5kWh ifuna iiseli ezili-16 ezinjalo, kunye necasing yebhetri enobunzima obuphakathi kwe-15-20kg. Ke, ubunzima bubonke buya kuba:

Iingcebiso: Uxinzelelo lwamandla = Umthamo / (Ubunzima beSeli + Ubunzima bebhokisi)

Ngamanye amazwi, a5kWh ibhetri yasekhayakusetyenziswa iiSeli zeLiFePO4 zeBanga A kufuneka zibenobuninzi bamandla obuyi-90.90Wh/kg ubuncinane. Ngokweenkcukacha zemodeli ye-BSLBATT ye-Li-PRO 5120, ubuninzi bamandla yi-101.79Wh/kg, ehambelana ngokusondeleyo nedatha ye-EVE kunye neeseli ze-REPT.

Inyathelo lesi-2: Vavanya ubunzima beeseli

Ngokusekelwe kwidatha evela kubavelisi abane abakhokelayo, ubunzima beseli enye ye-3.2V 100Ah yeBanga A LiFePO4 malunga ne-2kg. Ukusuka koku, singabala:

Ibhetri ye-16S1P 51.2V 100Ah iya kuba nobunzima be-32kg, kunye nobunzima be-casing malunga ne-20kg, ubunzima obupheleleyo be-52kg.
Ibhetri ye-16S2P 51.2V 200Ah iya kuba nobunzima be-64kg, kunye nobunzima be-casing malunga ne-30kg, ubunzima obupheleleyo be-94kg.

(Abenzi abaninzi ngoku basebenzisa ngokuthe ngqo i-3.2V 200Ah iiseli ze-51.2V 200Ah iibhetri, ezifana ne-BSLBATT'sLi-PRO 10240. Umgaqo wokubala uhlala ufana.)

Ke, xa uphonononga iikowuteshini, nikela ingqalelo kubunzima bebhetri obunikwe ngumenzi. Ukuba ibhetri inzima ngokugqithisileyo, iiseli ezisetyenzisiweyo zinomgangatho othandabuzekayo kwaye ngokuqinisekileyo ayizizo iiSeli zeLiFePO4 zeBanga A.

Ngokuveliswa ngobuninzi bezithuthi zombane, iibhetri ezininzi ze-EV ezidla umhlala-phantsi zisetyenziselwa ukugcinwa kwamandla. Ezi seli ziye zafumana amawaka emijikelezo yentlawulo, zinciphisa kakhulu ubomi bomjikelezo kunye nemeko yempilo (SOH) yeeseli ze-LiFePO4, ezinokushiya kuphela i-70% okanye ngaphantsi kwamandla abo okuqala. Ukuba iiseli ezisetyenzisiweyo zisetyenziselwa ukwenza iibhetri zasekhaya, ukuphumeza okufanayo10kWh umthamo ungafuna iiseli ezininzi, okukhokelela kwibhetri enzima.

Ngokulandela la manyathelo mabini, uya kukwazi ukuba yingcaphephe yebhetri ekwaziyo ukuchonga ngokuzithemba ukuba ibhetri yakho yenziwe ngeeSeli zeLiFePO4 zeBanga le-A, nto leyo eyenza le ndlela ibe luncedo ngakumbi kubasasazi bezixhobo zesola okanye abathengi abaphakathi kwimarike.

Ewe kunjalo, ukuba uyingcali kwintsimi yamandla avuselelekayo ngokufikelela kwizixhobo zokuvavanya ibhetri, unokuphinda uvavanye ezinye iiparitha zobugcisa ezifana nomthamo, ukuchasana kwangaphakathi, izinga lokuzikhupha, kunye nokubuyisela amandla ukumisela ngokuchanekileyo ngakumbi ibakala leseli.

Iingcebiso zokugqibela

Njengoko imarike yokugcina amandla iqhubeka nokwandisa, iimveliso ezininzi kunye nabavelisi ziya kuvela. Xa ukhetha umthengisi, soloko ulumkela abo banikezela ngamaxabiso aphantsi ngokukrokrayo okanye iinkampani ezisanda kusekwa, njengoko zinokubeka umngcipheko kwishishini lakho. Abanye abathengisi banokude basebenzise iiSeli zeLiFePO4 zeBanga A ukuvelisa iibhetri zasekhaya kodwa bawubaxe owona mthamo. Umzekelo, ibhetri eyenziwe nge-3.2V 280Ah iiseli ezenza i-51.2V 280Ah ibhetri iya kuba nomthamo we-14.3kWh, kodwa umthengisi unokuyithengisa njenge-15kWh ngenxa yokuba amandla asondele. Oku kunokulahlekisa ekucingeni ukuba ufumana ibhetri eyi-15kWh ngexabiso eliphantsi, kanti enyanisweni iyi-14.3kWh kuphela.

Ukukhetha umboneleli webhetri yasekhaya othembekileyo nonobuchule ngumsebenzi onzima. Ngokhetho oluninzi olukhoyo, kulula ukonganyelwa. Yiyo loo nto sicebisa ukuba sijongeBSLBATT, umenzi onamava angaphezu kwama-20 eminyaka kwishishini lebhetri. Ngelixa amaxabiso ethu esenokungabi ngawona aphantsi, umgangatho wemveliso yethu kunye nenkonzo yethu iqinisekisiwe ukuba iya kushiya imbonakalo ehlala ihleli. Oku kusekelwe kumbono wethu we-brand: ukubonelela ngezona zisombululo zebhetri ze-lithium, yingakho sihlala sigxininisa ekusebenziseni iBanga A LiFePO4 Iiseli.
