Nhanganyaya:
Lithium mabhatiri ari kwese kwese muhupenyu hwedu. Mabhatiri edu enharembozha uye mabhatiri emotokari yemagetsi zveselithium mabhatiri, asi iwe unoziva mamwe mazwi ebhatiri ekutanga, marudzi ebhatiri, uye basa uye mutsauko webhatiri akatevedzana uye parallel kubatana? Ngationgororei ruzivo rwemabhatiri neHeltec.
Basic terminology ye lithium mabhatiri
1) C-chiyero
Inoreva chiyero cheyazvino kune yezita simba re lithium bhatiri panguva yekuchaja nekuburitsa. Inotsanangura kuti bhatiri rinogona sei kuchajwa nekuburitswa. Mitengo yekuchaja uye yekuburitsa haina kufanana. Semuyenzaniso:
1C: buritsa bhatiri zvizere mukati meawa 1 (yakazara charge)
0.2C: buritsa bhatiri zvizere mukati meawa 5 (yakazara charge)
5C: buritsa bhatiri zvizere mukati meawa 0.2 (yakazara charge)
2) Kugona
Huwandu hwemagetsi akachengetwa mulithium bhatiri. Iyo unit ndeye mAh kana Ah.
Yakasanganiswa nechiyero, semuenzaniso, kana bhatiri iri 4800mAh uye chiyero chekuchaja chiri 0.2C, zvinoreva kuti zvinotora maawa mashanu kuti bhatiri rizadzwe zvakazara kubva isina chinhu (kuregeredza danho rekutanga-chaja kana bhatiri yakaderera kwazvo).
Iko kuchaja ikozvino: 4800mA*0.2C=0.96A
3) BMS bhatiri manejimendi system
Iyo sisitimu inodzora uye inobata kuchaja / kuburitsa bhatiri, inoona tembiricha uye voltage yebhatiri, inobatanidza neiyo host system, inoyera bhatiri voltage, uye inogadzirisa kuchengetedzwa kwekuita kwe lithium battery pack.
4) Kutenderera
Maitiro ekuchaja uye kuburitsa bhatiri kunonzi kutenderera. Kana bhatiri rinongoshandisa 80% yesimba rayo rose nguva imwe neimwe, hupenyu hwemabhatiri e-lithium-ion hunogona kunge hwakakwira sezviuru zvenguva.
Lithium Battery Type
Parizvino, masero ekutengesa lithium-ion anonyanya cylindrical, square uye soft-pack.
18650 cylindrical masero ndiwo masero e-lithium-ion ane huwandu hwepamusoro hwekugadzira parizvino. Yedu G yakatevedzana yekutarisa bhatiri maseru ndeerudzi urwu.
Cell series uye parallel connection
Sero ndicho chikamu chikuru chelithium bhatiri. Nhamba yemasero inosiyana zvichienderana nekushandiswa kwebhatiri, asi mabhatiri ese anoda kubatanidzwa nenzira dzakasiyana kuti awane voltage inodiwa uye simba.
Ongorora: Mamiriro ekubatanidza akaenzana ane hasha. Naizvozvo, parallel yekubatanidza kutanga uyezve nhevedzano yekubatanidza inogona kuderedza zvinodikanwa zvebhatiri kuenderana.
Mubvunzo: Ndeupi musiyano uripo pakati pematatu-series uye mana-parallel uye mana-parallel uye matatu-akatevedzana mabhatiri?
A: The voltage uye simba zvakasiyana.Series yekubatanidza inowedzera voltage, uye parallel yekubatanidza inowedzera ikozvino (simba)
1) Parallel kubatana
Fungidzira kuti voltage yebhatiri cell ndeye 3.7V uye huwandu hwayo ndeye 2.4Ah. Mushure mekubatana kwakafanana, iyo terminal voltage ye system ichiri 3.7V, asi huwandu hunowedzera kusvika 7.2Ah.
2) Series yekubatanidza
Fungidzira kuti voltage yebhatiri cell ndeye 3.7V uye huwandu hwayo ndeye 2.4Ah. Mushure mekubatanidza kwakatevedzana, iyo terminal voltage yeiyo system ndeye 11.1V, uye huwandu hunoramba husina kuchinjika.
Kana bhatiri sero iri matatu akatevedzana uye maviri akafanana, anokwana 6 18650 masero, ipapo bhatiri iri 11.1V uye 4.8Ah. Tesla Model-S sedan inoshandisa masero ePanasonic 18650, uye 85kWh bhatiri paki inoda maseru zviuru zvinomwe.
Mhedziso
Heltec icharamba ichivandudza ruzivo rwakakurumbira rwesainzi nezvelithium mabhatiri. Kana iwe uchifarira, iwe unogona kuiteerera. Panguva imwecheteyo, tinokupa iwe yepamusoro-mhando lithium bhatiri mapaketi kuti iwe utenge uye upe masevhisi akagadziridzwa kuti asangane nezvido zvako.
Heltec Energy ishamwari yako yaunovimba nayo mukugadzira bhatiri pack. Nekutarisa kwedu kusingagumi pakutsvaga nekusimudzira, pamwe nehupamhi hwemabhatiri ezvishandiso zvedu, tinopa mhinduro imwe chete yekusangana nezvinodiwa neindasitiri. Kuzvipira kwedu kune kugona, mhinduro dzakagadzirirwa, uye kudyidzana kwakasimba kwevatengi kunotiita isu kuenda-kune sarudzo yevagadziri vebhatiri pack uye vatengesi pasi rese.
Kana uine chero mibvunzo kana uchida kudzidza zvakawanda, ndapota usazezasvika kwatiri.
