Kutsegula Zinsinsi za Kuwona Ma cell a LiFePO4 a Gulu A

Ndi chitukuko chofulumira cha kusungirako mphamvu zongowonjezwdwa, opanga osawerengeka ndi ogulitsaMabatire a LiFePO4zapezeka ku China. Komabe, khalidwe la opanga awa limasiyana kwambiri. Ndiye, mungawonetse bwanji kuti batire lanyumba lomwe mumagula lapangidwa ndi Ma cell a Grade A LiFePO4?

Ku China, maselo a LiFePO4 amagawidwa m'magulu asanu:

-GALADI A+
-GALADI A-
– GRADE B
-GRADE C
- ZOGWIRITSIDWAPO KALE NTCHITO

Onse giredi A+ ndi GRADE A- amaonedwa ngati Maselo a LiFePO4 a Giredi A. Komabe, GRADE A- imasonyeza ntchito yotsika pang'ono ponena za mphamvu zonse, kusasinthasintha kwa selo, ndi kukana kwa mkati.

Momwe Mungadziwire Mwamsanga Maselo a LiFePO4 a Giredi A?

Ngati ndinu ogawa zida za sola kapena oyikapo omwe mukugwira ntchito ndi batire yatsopano, mungadziwe bwanji mwachangu ngati woperekayo akukupatsani Ma cell a Grade A LiFePO4? Tsatirani izi, ndipo mupeza luso lofunikali mwachangu.

Khwerero 1: Unikani Kachulukidwe Wa Mphamvu Za Maselo

Tiyeni tiyambe ndi kufananiza kachulukidwe mphamvu ya 3.2V 100Ah LiFePO4 maselo kuchokera pamwamba asanu opanga mphamvu batire ku China:

MFUNDO: Kuchuluka kwa Mphamvu = Mphamvu / Kulemera

Kuchokera pazidziwitso izi, tikhoza kunena kuti Maselo a LiFePO4 a Giredi A kuchokera kwa opanga otsogola ali ndi mphamvu zosachepera 140Wh/kg. Nthawi zambiri, batire yakunyumba ya 5kWh imafuna ma cell 16 oterowo, ndi batire yolemera mozungulira 15-20kg. Choncho, kulemera konse kudzakhala:

MFUNDO: Kuchuluka kwa Mphamvu = Mphamvu / (Kulemera kwa cell + kulemera kwa bokosi)

M'mawu ena, a5kWh batire lanyumbapogwiritsa ntchito Maselo a LiFePO4 a Giredi A ayenera kukhala ndi mphamvu zosachepera 90.90Wh/kg. Malinga ndi mafotokozedwe a mtundu wa BSLBATT wa Li-PRO 5120, kuchuluka kwa mphamvu ndi 101.79Wh/kg, komwe kumagwirizana kwambiri ndi data ya ma cell a EVE ndi REPT.

Gawo 2: Unikani Kulemera kwa Maselo

Kutengera zomwe zachokera kwa opanga anayi otsogola, kulemera kwa selo limodzi la 3.2V 100Ah Grade A LiFePO4 ndi pafupifupi 2kg. Kuchokera apa, tikhoza kuwerengera:

- Batire ya 16S1P 51.2V 100Ah imatha kulemera 32kg, kuphatikiza kulemera kwa casing kuzungulira 20kg, kulemera kwathunthu kwa 52kg.
- Batire la 16S2P 51.2V 200Ah likhoza kulemera 64kg, kuphatikizapo kulemera kwa casing kuzungulira 30kg, kulemera kwake kwa 94kg.

(Opanga ambiri tsopano amagwiritsa ntchito mwachindunji ma cell a 3.2V 200Ah a mabatire a 51.2V 200Ah, monga BSLBATT'sLi-PRO 10240. Mfundo yowerengera imakhala yofanana.)

Choncho, powerenga ndemanga, samalani kwambiri ndi kulemera kwa batri loperekedwa ndi wopanga. Ngati batire ndi yolemera kwambiri, ma cell omwe amagwiritsidwa ntchito amakhala okayikitsa ndipo sali Ma cell a LiFePO4 a Giredi A.

Ndi kupanga kwakukulu kwa magalimoto amagetsi, mabatire ambiri a EV omwe adapuma pantchito amasinthidwanso kuti asungidwe mphamvu. Maselo amenewa nthawi zambiri adutsa maulendo ambirimbiri, kuchepetsa kwambiri moyo ndi thanzi labwino (SOH) la maselo a LiFePO4, zomwe zingathe kusiya 70% kapena zochepa za mphamvu zawo zoyambirira. Ngati maselo achiwiri amagwiritsidwa ntchito popanga mabatire apanyumba, kukwaniritsa zomwezo10kw pa kuchuluka kumafunika ma cell ochulukirapo, zomwe zimapangitsa kuti pakhale batire yolemera.

Potsatira njira ziwirizi, mudzatha kukhala katswiri wa batri yemwe angadziwe molimba mtima ngati batire yanu imapangidwa ndi Ma cell A LiFePO4, zomwe zimapangitsa kuti njirayi ikhale yothandiza kwambiri kwa ogawa zida zamagetsi kapena makasitomala amsika.

Zachidziwikire, ngati ndinu katswiri pantchito yamagetsi yongowonjezwdwa ndi mwayi wopeza zida zoyezera batire, mutha kuwunikanso magawo ena aukadaulo monga mphamvu, kukana kwamkati, kutsika kwamadzimadzi, komanso kubwezeretsa mphamvu kuti muzindikire bwino kalasi ya cell.

Malangizo Omaliza

Pamene msika wosungiramo mphamvu ukupitiriza kukula, malonda ndi opanga ambiri adzatulukira. Posankha wogulitsa, nthawi zonse samalani ndi omwe amapereka mitengo yotsika mokayikira kapena makampani omwe angokhazikitsidwa kumene, chifukwa atha kuyika bizinesi yanu pachiwopsezo. Ena ogulitsa amatha kugwiritsa ntchito Ma cell a LiFePO4 a Grade A kupanga mabatire akunyumba koma amakokomeza kuchuluka kwake. Mwachitsanzo, batire yopangidwa ndi ma cell a 3.2V 280Ah yomwe imapanga batire ya 51.2V 280Ah idzakhala ndi mphamvu ya 14.3kWh, koma wogulitsa akhoza kuitsatsa ngati 15kWh chifukwa mphamvu zake zili pafupi. Izi zingasocheretseni poganiza kuti mukupeza batire ya 15kWh pamtengo wotsika, pomwe kwenikweni, ndi 14.3kWh yokha.

Kusankha wothandizira batire yodalirika komanso akatswiri kunyumba ndi ntchito yovuta. Pokhala ndi zosankha zambiri zomwe zilipo, ndizosavuta kugonja. Ichi ndichifukwa chake timalimbikitsa kuyang'anaMtengo wa BSLBATT, wopanga yemwe ali ndi zaka zopitilira 20 mumakampani opanga mabatire. Ngakhale mitengo yathu singakhale yotsika kwambiri, mtundu wathu wazinthu ndi ntchito zimatsimikizika kuti zisiya kuwoneka kwamuyaya. Izi zimachokera mu masomphenya athu: kupereka njira zabwino kwambiri za batri ya lithiamu, chifukwa chake nthawi zonse timalimbikira kugwiritsa ntchito Ma cell A LiFePO4.
