Ka tsoelo-pele e potlakileng ea polokelo ea matla a tsosolositsoeng, bahlahisi ba se nang palo le bafani baLi-betri tsa LiFePO4li hlahile China. Leha ho le joalo, boleng ba baetsi bana bo fapana haholo. Joale, u ka etsa bonnete ba hore betri ea lapeng eo u e rekang e entsoe ka Lisele tsa Grade A LiFePO4?
Chaena, lisele tsa LiFePO4 hangata li arotsoe ka lihlopha tse hlano:
- MPHATO A+
– MPHATO A-

- E SEBELITSENG
Ka bobeli GRADE A+ le GRADE A- li nkoa e le Lisele tsa Kereiti ea A LiFePO4. Leha ho le joalo, GRADE A- e bonts'a ts'ebetso e fokolang hanyenyane ho latela matla a feletseng, ho lumellana ha lisele, le ho hanyetsa ka hare.
Mokhoa oa ho Khetholla Lisele tsa LiFePO4 tsa Kereiti ea A kapele?
Haeba u sephatlalatsi sa lisebelisoa tsa letsatsi kapa sehlomathisi se sebetsang le mofani oa thepa e ncha ea betri, u ka tseba joang kapele hore na mofani oa thepa o u fa Lisele tsa LiFePO4 tsa Kereiti ea A? Latela mehato ena, 'me u tla potlakela ho fumana tsebo ena ea bohlokoa.
Mohato oa 1: Lekola Matla a Matla a Lisele
Ha re qaleng ka ho bapisa matla a matla a lisele tsa 3.2V 100Ah LiFePO4 ho tsoa ho baetsi ba betri ba polokelo ea matla ba bahlano ba holimo Chaena:
| Brand | Boima ba 'mele | Tlhaloso | Bokhoni | Matla a Matla |
| EVE | 1.98kg | 3.2V 100Ah | 320Wh | 161Wh/kg |
| REPT | 2.05kg | 3.2V 100Ah | 320Wh | 150Wh/kg |
| CATL | 2.27kg | 3.2V 100Ah | 320Wh | 140Wh/kg |
| BYD | 1.96kg | 3.2V 100Ah | 320Wh | 163Wh/kg |
Malebela: Matla a Matla = Bokhoni / Boima
Ho tsoa boitsebisong bona, re ka etsa qeto ea hore Lisele tsa LiFePO4 tsa Sehlopha sa A tse tsoang ho bahlahisi ba ka sehloohong li na le matla a matla a bonyane 140Wh/kg. Ka tloaelo, betri ea lapeng ea 5kWh e hloka lisele tse joalo tse 16, ka mokotla oa betri o boima ba 15-20kg. Kahoo, boima ba 'mele kaofela e tla ba:
| Brand | Boima ba Seleng | Boima ba Lebokose | Tlhaloso | Bokhoni | Matla a Matla |
| EVE | 31.68kg | 20kg | 51.2V 100Ah | 5120Wh | 99.07Wh/kg |
| REPT | 32.8kg | 20kg | 51.2V 100Ah | 5120Wh | 96.96Wh/kg |
| CATL | 36.32kg | 20kg | 51.2V 100Ah | 5120Wh | 90.90Wh/kg |
| BYD | 31.36kg | 20kg | 51.2V 100Ah | 5120Wh | 99.68Wh/kg |
Malebela: Boima ba Matla = Bokhoni / (Boima ba lisele + boima ba Lebokose)
Ka mantsoe a mang, a5kWh betri ea lapengho sebelisa Lisele tsa LiFePO4 tsa Sehlopha sa A li lokela ho ba le matla a matla a bonyane 90.90Wh/kg. Ho ea ka litlhaloso tsa mofuta oa BSLBATT oa Li-PRO 5120, matla a matla ke 101.79Wh/kg, e tsamaellanang haufi-ufi le data bakeng sa lisele tsa EVE le REPT.
Mohato oa 2: Lekola Boima ba Lisele
Ho ipapisitsoe le lintlha tse tsoang ho baetsi ba bane ba etelletseng pele, boima ba sele e le 'ngoe ea 3.2V 100Ah Grade A LiFePO4 ke hoo e ka bang 2kg. Ho tloha ho sena, re ka bala:
- Betri ea 16S1P 51.2V 100Ah e ne e tla ba boima ba 32kg, hammoho le boima ba casing bo ka bang 20kg, bakeng sa boima bohle ba 52kg.
- Betri ea 16S2P 51.2V 200Ah e ne e tla ba boima ba 64kg, hammoho le boima ba casing bo ka bang 30kg, bakeng sa boima bohle ba 94kg.
(Bahlahisi ba bangata hajoale ba sebelisa lisele tsa 3.2V 200Ah ka kotloloho bakeng sa libeteri tsa 51.2V 200Ah, joalo ka BSLBATT's.Li-PRO 10240. Molao-motheo oa lipalo o lula o tšoana.)
Kahoo, ha u hlahloba mantsoe a qotsitsoeng, ela hloko haholo boima ba betri bo fanoeng ke moetsi. Haeba betri e le boima bo feteletseng, lisele tse sebelisoang li ka 'na tsa e-ba tsa boleng bo belaetsang 'me ka sebele ha se Lisele tsa LiFePO4 tsa Kereiti ea A.
Ka tlhahiso e kholo ea likoloi tsa motlakase, libeteri tse ngata tsa EV tse tlohetseng mosebetsi li khutlisetsoa ho boloka matla. Lisele tsena li 'nile tsa e-ba le lipotoloho tse likete tsa litefiso, li fokotsa haholo bophelo ba potoloho le boemo ba bophelo bo botle (SOH) ea lisele tsa LiFePO4, tse ka 'nang tsa siea feela 70% kapa ka tlaase ho matla a bona a pele. Haeba lisele tsa letsoho la bobeli li sebelisoa ho etsa libeteri tsa lapeng, ho fihlela se tšoanang10kWh matla a ka hloka lisele tse ngata, ho fella ka betri e boima ho feta.
Ka ho latela mehato ena e 'meli, u tla khona ho ba setsebi se hloahloa sa betri se ka tsebang ka kholiseho hore na betri ea hau e entsoe ka Lisele tsa LiFePO4 tsa Kereiti ea A, e leng se etsang hore mokhoa ona e be oa bohlokoa haholo ho barekisi ba lisebelisoa tsa letsatsi kapa bareki ba limmaraka tse bohareng.
Ha e le hantle, haeba u setsebi lefapheng la matla a tsosolositsoeng le ho fumana lisebelisoa tsa tlhahlobo ea betri, u ka boela ua lekola likarolo tse ling tsa tekheniki tse kang bokhoni, khanyetso ea ka hare, sekhahla sa ho itšehla thajana, le ho hlaphoheloa ha matla ho tseba hantle hore na boemo ba lisele ke bofe.
Malebela a ho Qetela
Ha 'maraka oa polokelo ea matla o ntse o tsoela pele ho atoloha, lihlahisoa tse ngata le bahlahisi ba tla hlaha. Ha u khetha mofani oa thepa, lula u le hlokolosi ho ba fanang ka litheko tse tlase ka mokhoa o belaetsang kapa lik'hamphani tse sa tsoa thehoa, kaha li ka beha khoebo ea hau kotsing. Barekisi ba bang ba ka ba ba sebelisa Lisele tsa LiFePO4 tsa Kereiti ea A ho hlahisa libeteri tsa lapeng empa ba feteletsa matla a sebele. Mohlala, betri e entsoeng ka lisele tsa 3.2V 280Ah tse etsang betri ea 51.2V 280Ah e tla ba le matla a 14.3kWh, empa morekisi a ka e bapatsa e le 15kWh hobane matla a haufi. Sena se ka u khelosa hore u nahane hore u fumana betri ea 15kWh ka theko e tlaase, athe ha e le hantle, ke 14.3kWh feela.
Ho khetha morekisi ea tšepahalang le ea hloahloa oa betri ea lapeng ke mosebetsi o boima. Ka likhetho tse ngata tse fumanehang, ho bonolo ho tsieleha. Ke kahoo re khothalletsang ho sheba hoBSLBATT, moetsi ea nang le phihlelo ea lilemo tse fetang 20 indastering ea betri. Leha litheko tsa rona li kanna tsa se be tlase ho fetisisa, boleng ba sehlahisoa sa rona le ts'ebeletso li netefalitsoe ho siea maikutlo a sa feleng. Sena se thehiloe ponong ea mofuta oa rona: ho fana ka tharollo e ntle ka ho fetisisa ea betri ea lithium, ke ka lebaka leo re lulang re tsitlallela ho sebelisa Lisele tsa Grade A LiFePO4.
