Me ka hoʻomohala wikiwiki o ka mālama ʻana i ka ikehu hou, helu ʻia nā mea hana a me nā mea hoʻolakoLiFePO4 mau pilaua puka mai ma Kina. Eia naʻe, ʻokoʻa ka maikaʻi o kēia mau mea hana. No laila, pehea e hiki ai iā ʻoe ke hōʻoia i ka hana ʻana o ka pā hale āu e kūʻai ai me nā Pūnaewele LiFePO4 Grade A?
Ma Kina, hoʻokaʻawale pinepine ʻia nā cell LiFePO4 i ʻelima mau māka:
- PAPA A+
- PAPA A-
– PAPA B
– PAPA C
– LIMA LUA
ʻO GRADE A+ a me GRADE A- ua manaʻo ʻia ʻo Grade A LiFePO4 Cells. Eia naʻe, hōʻike ʻo GRADE A- i ka hana haʻahaʻa haʻahaʻa ma ke ʻano o ka nui o ka hiki, ka paʻa o ke kelepona, a me ke kūpaʻa kūloko.
Pehea e ʻike koke ai i nā pūnaewele LiFePO4 Grade A?
Inā he mea hoʻolaha lako lā ʻoe a mea hoʻonohonoho paha e hana pū ana me kahi mea hoʻolako pākaukau hou, pehea ʻoe e hoʻoholo koke ai inā hāʻawi ka mea hoʻolako iā ʻoe i nā Kelepona LiFePO4 Grade A? E hahai i kēia mau ʻanuʻu, a e loaʻa koke iā ʻoe kēia akamai waiwai.
KaʻAnuʻu Hana 1: E loiloi i ka ikaika o ka ikehu o nā pūnaewele
E hoʻomaka kākou ma ka hoʻohālikelike ʻana i ka nui o ka ikehu o 3.2V 100Ah LiFePO4 pūnaewele mai nā mea hana ʻelima hoʻopaʻa uila ma Kina:
| Brand | Kaumaha | Hōʻike | Ka hiki | ʻAiʻi ikaika |
| EVE | 1.98 kg | 3.2V 100Ah | 320Wh | 161Wh/kg |
| REPT | 2.05 kg | 3.2V 100Ah | 320Wh | 150Wh/kg |
| CATL | 2.27 kg | 3.2V 100Ah | 320Wh | 140Wh/kg |
| BYD | 1.96 kg | 3.2V 100Ah | 320Wh | 163Wh/kg |
Nā Manaʻo Manaʻo: ʻO ka ikaika o ka ikehu = Kaha / Kaumaha
Mai kēia ʻikepili, hiki iā mākou ke hoʻoholo i ka pae A LiFePO4 Cells mai nā mea hana alakaʻi i loaʻa ka ikehu o ka liʻiliʻi o 140Wh/kg. ʻO ka maʻamau, pono ka pā hale 5kWh i 16 mau pūnae like, me ke kaupaona ʻana o ka pahu pākaukau ma kahi o 15-20kg. No laila, ʻo ka nui o ke kaumaha:
| Brand | Kaumaha Cell | Kaumaha pahu | Hōʻike | Ka hiki | ʻAiʻi ikaika |
| EVE | 31.68kg | 20 kg | 51.2V 100Ah | 5120Wh | 99.07Wh/kg |
| REPT | 32.8kg | 20 kg | 51.2V 100Ah | 5120Wh | 96.96Wh/kg |
| CATL | 36.32 kg | 20 kg | 51.2V 100Ah | 5120Wh | 90.90Wh/kg |
| BYD | 31.36kg | 20 kg | 51.2V 100Ah | 5120Wh | 99.68Wh/kg |
Manaʻo Manaʻo: ʻAiʻikaʻi o ka ikehu = Kaha / (Ke kaumaha o ke kelepona + kaumaha pahu)
ʻO ia hoʻi, a5kWh pā haleme ka hoʻohana ʻana i ka Papa A LiFePO4 Cells pono e loaʻa ka ikehu o ka liʻiliʻi o 90.90Wh/kg. Wahi a nā kikoʻī o ka BSLBATT's Li-PRO 5120 model, ʻo 101.79Wh/kg ka nui o ka ikehu, e pili pono ana me ka ʻikepili no nā cell EVE a me REPT.
KaʻAnuʻu 2: E loiloi i ke kaumaha o nā pūnaewele
Ma muli o ka ʻikepili mai nā mea hana nui ʻehā, ʻo ke kaumaha o kahi cell 3.2V 100Ah Grade A LiFePO4 ma kahi o 2kg. Mai kēia, hiki iā mākou ke helu:
- He 32kg ke kaumaha o kahi pākahiko 16S1P 51.2V 100Ah, me ke kaumaha o ka pahu ma kahi o 20kg, no ka nui o 52kg.
- He 64kg ke kaumaha o kahi pākahiko 16S2P 51.2V 200Ah, me ke kaumaha o ka pahu ma kahi o 30kg, no ka nui o 94kg.
(He nui nā mea hana i kēia manawa e hoʻohana pololei i nā pūnaewele 3.2V 200Ah no nā pihi 51.2V 200Ah, e like me BSLBATT'sLi-PRO 10240. Ua like nō ke kumu helu helu.)
No laila, i ka nānā ʻana i nā huaʻōlelo, e nānā pono i ka paona pākaukau i hāʻawi ʻia e ka mea hana. Inā ʻoi aku ke kaumaha o ka pākaukau, ʻaʻole kānalua ka maikaʻi o nā cell i hoʻohana ʻia a ʻaʻole ia he mau Pūnaewele LiFePO4 Grade A.
Me ka hana nui ʻana o nā kaʻa uila, ua hoʻohana hou ʻia nā pā uila EV he nui no ka mālama ʻana i ka ikehu. ʻO kēia mau keena i hana maʻamau i nā tausani o nā pōʻai hoʻoili, e hōʻemi nui ana i ke ola pōʻaiapuni a me ke kūlana o ke olakino (SOH) o nā cell LiFePO4, hiki ke waiho wale ʻia he 70% a i ʻole ka liʻiliʻi o ko lākou hiki mua. Inā hoʻohana ʻia nā kelepona ʻelua no ka hana ʻana i nā pihi home, e loaʻa ana ka like10kWh ʻoi aku ka nui o nā pūnaewele, e loaʻa ana i kahi pākaukau kaumaha.
Ma ka hahai ʻana i kēia mau ʻanuʻu ʻelua, hiki iā ʻoe ke lilo i loea ʻoihana ʻoihana e hiki ke ʻike me ka hilinaʻi inā hana ʻia kāu pākaukau me Grade A LiFePO4 Cells, e hoʻohana pono i kēia ʻano hana no nā mea hoʻolaha lako lā a i ʻole nā mea kūʻai waena waena.
'Oia'i'o, inā he 'oihana 'oe ma ka 'oihana ikehu hou me ka loa'a 'ana i nā lako ho'ā'o pākaukau, hiki nō ho'i iā 'oe ke loiloi 'ē a'e nā palena 'enehana e like me ka hiki, ke kū'ē o loko, ka ho'oku'u 'ana iho, a me ka ho'iho'i 'ana i ka hiki ke ho'oholo pololei i ka helu kelepona.
Manaʻo Hope
Ke hoʻomau nei ka hoʻonui ʻana o ka mākeke mālama ikehu, ʻoi aku ka nui o nā hōʻailona a me nā mea hana. I ke koho ʻana i ka mea hoʻolako, e makaʻala mau i ka poʻe e hāʻawi ana i nā kumukūʻai haʻahaʻa kānalua a i ʻole nā hui hou i hoʻokumu ʻia, no ka mea hiki iā lākou ke pilikia i kāu ʻoihana. Hiki i kekahi mau mea hoʻolako ke hoʻohana i nā Kelepona LiFePO4 Grade A no ka hana ʻana i nā pihi home akā hoʻonui i ka mana maoli. No ka laʻana, ʻo kahi pākaukau i hana ʻia me nā kelepona 3.2V 280Ah e hana ana i kahi pākaukau 51.2V 280Ah e loaʻa i ka mana o 14.3kWh, akā hiki i ka mea hoʻolako ke hoʻolaha iā ia he 15kWh no ka mea ua kokoke nā mana. Hiki i kēia ke alakaʻi hewa iā ʻoe i ka noʻonoʻo ʻana e kiʻi ana ʻoe i kahi pākaukau 15kWh ma ke kumu kūʻai haʻahaʻa, ʻoiai, ʻo 14.3kWh wale nō.
He hana paʻakikī ke koho ʻana i kahi mea hoʻolako pākaukau home hilinaʻi a ʻoihana. Me ka nui o nā koho i loaʻa, ua maʻalahi ka hoʻoluhi. ʻO ia ke kumu a mākou e manaʻo ai e nānāBSLBATT, He mea hana me ka ʻoi aku o 20 mau makahiki o ka ʻike ma ka ʻoihana pākaukau. ʻOiai ʻaʻole ʻoi aku ka haʻahaʻa o kā mākou mau kumukūʻai, ua hōʻoia ʻia kā mākou huahana a me kā mākou lawelawe e waiho i kahi manaʻo mau loa. Hoʻokumu ʻia kēia i loko o kā mākou ʻike maka: e hāʻawi i nā hāmeʻa pākahi lithium maikaʻi loa, ʻo ia ke kumu e koi mau ai mākou i ka hoʻohana ʻana i nā Cells LiFePO4 Grade A.
