Loaʻa nā pākahi Lithium ma nā wahi āpau o ko mākou ola. ʻO kā mākou mau pihi kelepona paʻalima a me nā pihi kaʻa uilanā pākahi lithium, akā ʻike paha ʻoe i kekahi mau huaʻōlelo pākaukau maʻamau, nā ʻano pākaukau, a me ke kuleana a me ka ʻokoʻa o ka pūʻulu pākaukau a me ka pilina like? E ʻimi kākou i ka ʻike o nā pākahi me Heltec.
ʻO nā huaʻōlelo kumu o nā pākahi lithium
1) C-helu
E pili ana i ka ratio o kēia manawa i ka mana nominal o ka pā lithium i ka wā o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana. Hōʻike ia i ka wikiwiki o ka hiki ke hoʻopaʻa ʻia a hoʻokuʻu ʻia ka pākaukau. ʻAʻole like ka uku hoʻouka a me ka hoʻokuʻu ʻana. ʻo kahi laʻana:
1C: hoʻopau piha i ka pākaukau i loko o 1 hola (piha piha)
0.2C: hoʻopau piha i ka pākaukau i loko o 5 mau hola (piha piha)
5C: hoʻopau piha i ka pākaukau i loko o 0.2 mau hola (piha piha)
2) Hiki
Ka nui o ka uila i mālama ʻia i loko o kapākahi lithium. ʻO ka ʻāpana he mAh a i ʻole Ah.
Hoʻohui ʻia me ka pākēneka, no ka laʻana, inā he 4800mAh ka pākaukau a ʻo 0.2C ka nui o ka hoʻopiʻi ʻana, ʻo ia hoʻi he 5 mau hola no ka hoʻopiha piha ʻana o ka pila (e nānā ʻole i ka pae mua o ka hoʻopiʻi ʻana ke haʻahaʻa loa ka pila).
ʻO ka hoʻouka ʻana i kēia manawa: 4800mA * 0.2C=0.96A
3) Pūnaehana hoʻokele pākaukau BMS
Mālama ka ʻōnaehana a hoʻokele i ka hoʻopiʻi ʻana / hoʻokuʻu ʻana o ka pākaukau, ʻike i ka mahana a me ka volta o ka pākaukau, hoʻopili me ka ʻōnaehana hoʻokipa, hoʻopaʻa i ka uila uila, a mālama i ka hana palekana o ka pā uila lithium.
4) Kaapuni
ʻO ke kaʻina hana o ka hoʻouka ʻana a me ka hoʻokuʻu ʻana i kapa ʻia he pōʻaiapuni. Inā hoʻohana wale ka pākaukau i ka 80% o kona ikehu a pau i kēlā me kēia manawa, hiki ke kiʻekiʻe ke ola pōʻaiapuni o nā pā lithium-ion e like me nā tausani o nā manawa.
ʻAno Pāʻani Lithium
I kēia manawa, ʻoi aku ka nui o nā cell lithium-ion pāʻoihana cylindrical, square a soft-pack.
ʻO 18650 cylindrical cell nā pūnaewele lithium-ion me ka nui o ka hana i kēia manawa. ʻO kēia ʻano ʻano kā mākou G series monitor cell cell.
Pūʻulu pūnaewele a me ka pilina like
ʻO ke kelepona ka mea nui o kapākahi lithium. ʻOkoʻa ka helu o nā cell ma muli o ka noi ʻana o ka pākaukau, akā pono e hoʻopili ʻia nā ʻāpana āpau ma nā ʻano like ʻole e hoʻokō ai i ka volta a me ka mana.
'Ōlelo Aʻo: Paʻakikī loa nā kūlana no ka pili like. No laila, hiki i ka pilina pili mua a laila hiki ke ho'ēmi i nā koi no ka paʻa ʻana o ka pākaukau.
Nīnau: He aha ka ʻokoʻa ma waena o ʻekolu mau pūʻulu a me ʻehā mau ʻano like ʻole a me ʻehā-parallel a me ʻekolu mau pūʻulu?
A: He ʻokoʻa ka volta a me ka hiki.Hoʻonui ka pilina moʻo i ka uila, a hoʻonui ka hoʻohui like i kēia manawa (hiki)
1) Pili like
E noʻonoʻo ʻoe he 3.7V ka volta o ke kelepona a ʻo 2.4Ah ka mana. Ma hope o ka pili like ʻana, ʻo 3.7V ka hopena o ka ʻōnaehana, akā piʻi ka mana i 7.2Ah.
2) Hoʻohui moʻo
E noʻonoʻo ʻoe he 3.7V ka volta o ke kelepona a ʻo 2.4Ah ka mana. Ma hope o ka hoʻohui pū ʻana, ʻo ka volta terminal o ka ʻōnaehana he 11.1V, a ʻaʻole i loli ka mana.
Inā ʻekolu pūʻulu a me ʻelua mau ʻano like ʻole, he 6 18650 mau keena, a laila ʻo 11.1V a me 4.8Ah ka pila. Ke hoʻohana nei ʻo Tesla Model-S sedan i ka Panasonic 18650 cell, a ʻo kahi pūʻulu pākahi 85kWh e pono ai ma kahi o 7,000 mau kelepona.
Ka hopena
E hoʻomau ʻo Heltec i ka ʻike ʻepekema kaulana e pili ananā pākahi lithium. Inā hoihoi ʻoe, hiki iā ʻoe ke hoʻolohe iā ia. Ma ka manawa like, hāʻawi mākou iā ʻoe i nā pā uila lithium kiʻekiʻe no ʻoe e kūʻai a hāʻawi i nā lawelawe maʻamau e hoʻokō i kāu mau pono.
ʻO Heltec Energy kāu hoa hilinaʻi ma ka hana ʻana i ka pākaukau. Me ko mākou manaʻo hoʻomau i ka noiʻi a me ka hoʻomohala ʻana, i hui pū ʻia me kā mākou ʻāpana piha o nā lako pākaukau, hāʻawi mākou i nā ʻoluʻolu hoʻokahi e hoʻokō i nā pono e ulu nei o ka ʻoihana. ʻO kā mākou kūpaʻa i ka maikaʻi, nā hoʻonā i hoʻohālikelike ʻia, a me nā hui kūʻai ikaika e hoʻolilo iā mākou i ke koho koho no nā mea hana pākaukau a me nā mea hoʻolako ma ka honua holoʻokoʻa.
Inā he mau nīnau kāu a makemake paha e aʻo hou aku, e ʻoluʻolu e ʻoluʻolue launa mai ia makou.
