Intangiriro ：
Batteri ya Litiyumu iri hose mubuzima bwacu. Batteri ya terefone igendanwa na bateri yimodoka yamashanyarazi byosebateri ya lithium, ariko uzi amagambo yibanze ya bateri, ubwoko bwa bateri, ninshingano nibitandukaniro byuruhererekane rwa batiri no guhuza? Reka dusuzume ubumenyi bwa bateri hamwe na Heltec.
Ijambo ryibanze rya bateri ya lithium
1) C-igipimo
Yerekeza ku kigereranyo cyumuyaga nubushobozi bwa nomero ya batiri ya lithium mugihe cyo kwishyuza no gusohora. Irasobanura uburyo bateri ishobora kwishyurwa no gusohoka. Igipimo cyo kwishyuza no gusohora ntabwo byanze bikunze ari kimwe. Urugero:
1C: gusohora byuzuye bateri mugihe cyisaha 1 (byuzuye)
0.2C: gusohora byuzuye bateri mugihe cyamasaha 5 (byuzuye)
5C: gusohora byuzuye bateri mumasaha 0.2 (kwishyurwa byuzuye)
2) Ubushobozi
Umubare w'amashanyarazi wabitswe muriBatiri. Igice ni mAh cyangwa Ah.
Ufatanije nigipimo, kurugero, niba bateri ari 4800mAh naho igipimo cyo kwishyuza ni 0.2C, bivuze ko bisaba amasaha 5 kugirango bateri yishyurwe byuzuye kubusa (wirengagije icyiciro kibanziriza kwishyuza mugihe bateri iba mike cyane).
Umuyoboro w'amashanyarazi ni: 4800mA * 0.2C = 0.96A
3) Sisitemu yo gucunga bateri ya BMS
Sisitemu igenzura kandi ikayobora kwishyuza / gusohora bateri, ikamenya ubushyuhe na voltage ya bateri, igahuza na sisitemu yakira, ikaringaniza ingufu za bateri, kandi ikayobora imikorere yumutekano wapaki ya litiro.
4) Ukuzenguruka
Inzira yo kwishyuza bateri no gusohora yitwa cycle. Niba bateri ikoresha 80% yingufu zayo zose buri gihe, ubuzima bwinzira ya bateri ya lithium-ion irashobora kuba hejuru inshuro ibihumbi.
Ubwoko bwa Batiri ya Litiyumu
Kugeza ubu, lithium-ion yubucuruzi ni silindrike, kare na soft-pack.
18650 ingirabuzimafatizo ni selile ya lithium-ion ifite umusaruro mwinshi muri iki gihe. Urutonde rwa G rukurikirana selile ya selile ni ubu bwoko.
Urukurikirane rw'utugari hamwe no guhuza
Akazu ni ishingiro ryibanze ryaBatiri. Umubare w'utugingo turatandukanye bitewe nikoreshwa rya bateri, ariko bateri zose zigomba guhuzwa muburyo butandukanye kugirango ugere kumashanyarazi asabwa.
Icyitonderwa: Ibisabwa kugirango uhuze birakaze. Kubwibyo, guhuza kubanza hanyuma hanyuma urukurikirane rushobora kugabanya ibisabwa kugirango bateri ihoraho.
Ikibazo: Ni irihe tandukaniro riri hagati yuruhererekane rwibice bitatu na bine-bisa na bine-bine na bateri-eshatu?
Igisubizo: Umuvuduko nubushobozi biratandukanye.Ihuza ryuruhererekane ryongera voltage, kandi guhuza byongera imbaraga (ubushobozi)
1) Guhuza
Dufate ko voltage ya selile ya batiri ari 3.7V kandi ubushobozi ni 2.4Ah. Nyuma yo guhuza ibangikanye, imbaraga za terefone ya sisitemu iracyari 3.7V, ariko ubushobozi bwiyongera kuri 7.2Ah.
2) Guhuza urukurikirane
Dufate ko voltage ya selile ya batiri ari 3.7V kandi ubushobozi ni 2.4Ah. Nyuma yuruhererekane rwihuza, voltage yumurongo wa sisitemu ni 11.1V, kandi ubushobozi ntibuhinduka.
Niba selile ya bateri ari serie eshatu hamwe na parallel ebyiri, zose hamwe 6 18650, noneho bateri ni 11.1V na 4.8Ah. Tesla Model-S sedan ikoresha selile Panasonic 18650, naho paki ya 85kWh isaba selile zigera ku 7000.
Umwanzuro
Heltec izakomeza kuvugurura ubumenyi bwa siyanse buzwi kubyerekeyebateri ya lithium. Niba ubishaka, urashobora kubyitondera. Mugihe kimwe, turaguha ibikoresho bya batiri ya litiro nziza yo kugura kugirango ugure kandi utange serivisi yihariye kugirango uhuze ibyo ukeneye.
Ingufu za Heltec numufatanyabikorwa wawe wizewe mugukora ibicuruzwa. Hamwe no guhora twibanda kubushakashatsi niterambere, hamwe nuburyo butandukanye bwibikoresho bya batiri, dutanga igisubizo kimwe kugirango duhuze ibikenerwa ninganda. Ibyo twiyemeje kuba indashyikirwa, ibisubizo bikwiranye, hamwe nubufatanye bukomeye bwabakiriya bituma duhitamo guhitamo abakora ibicuruzwa bya batiri nabatanga ibicuruzwa kwisi yose.
Niba ufite ikibazo cyangwa ushaka kwiga byinshi, nyamuneka ntutindiganyeutugereho.
