Intangiriro:
Bateri za Lithium ziri ahantu hose mu buzima bwacu. Bateri za telefoni zigendanwa zacu na bateri z'imodoka zikoresha amashanyarazi byose biribateri za litiyumu, ariko uzi amagambo y'ibanze ya bateri, ubwoko bwa bateri, n'uruhare n'itandukaniro rya bateri n'ihuza ryazo? Reka turebe ubumenyi bwa bateri dukoresheje Heltec.
Amagambo y'ibanze ya bateri za lithiamu
1) Igipimo cya C
Bivuga ku gipimo cy'umuvuduko w'amashanyarazi n'ubushobozi bwa bateri ya lithium mu gihe cyo gusharija no gusohora umuriro. Bisobanura uburyo bateri ishobora gusharija no gusohora umuriro vuba. Igipimo cyo gusharija no gusohora umuriro ntabwo ari ngombwa ko kiba kimwe. Urugero:
1C: sohora bateri yose mu gihe cy'isaha imwe (gutanga umuriro wose)
0.2C: sohora batiri yose mu masaha 5 (ishyuzwa ryuzuye)
5C: sohora batiri yose mu masaha 0.2 (ishyuzwa ryuzuye)
2) Ubushobozi
Ingano y'amashanyarazi abitswe muribateri ya litiyumu.Iyo mashini ni mAh cyangwa Ah.
Urugero, iyo bateri ifite 4800mAh kandi igiciro cyo kuyishyuza kikaba 0.2C, bivuze ko bifata amasaha 5 kugira ngo bateri ibe yuzuye ivuyemo ubusa (twirengagije igihe cyo kuyishyuza mbere yo kuyishyuza iyo bateri iri hasi cyane).
Umuvuduko wo gusharija ni: 4800mA*0.2C=0.96A
3) Sisitemu yo gucunga bateri za BMS
Sisitemu igenzura kandi igacunga uburyo bateri ikoresha amashanyarazi, ikamenya ubushyuhe n'amashanyarazi bya bateri, igahuza na sisitemu ikoresha amashanyarazi, igahuza ingufu za bateri, kandi igacunga imikorere y'umutekano wa bateri ya lithiamu.
4) Igare
Uburyo bwo gusharija no gusohora batiri bwitwa cycle. Iyo batiri ikoresha 80% gusa by'ingufu zayo zose buri gihe, igihe cy'ubuzima bwa batiri za lithium-ion gishobora kuba kinini cyane inshuro ibihumbi.
Ubwoko bwa bateri ya Lithium
Muri iki gihe, uturemangingo twa lithium-ion tw’ubucuruzi ahanini ni uruziga, kare n’udupfunyika tworoshye.
Uturemangingo 18650 tw’umubumbe ni two tugize litiyumu-iyoni dufite umusaruro mwinshi cyane muri iki gihe. Uturemangingo twa bateri dukoresha G series ni utwo duce.
Uruhererekane rw'uturemangingo n'ihuza ryabyo mu buryo buhuriweho
Akaremangingo ni cyo gice cy'ingenzi cy'bateri ya litiyumuUmubare w'uturemangingo uratandukanye bitewe n'ikoreshwa rya bateri, ariko bateri zose zigomba guhuzwa mu buryo butandukanye kugira ngo zigere ku muvuduko n'imbaraga bikenewe.
Icyitonderwa: Imiterere yo guhuza kuri parallel irakomeye cyane. Kubwibyo, guhuza kuri parallel mbere na nyuma yo guhuza kuri serivise bishobora kugabanya ibisabwa kugira ngo bateri irusheho kuba nziza.
Q: Ni irihe tandukaniro riri hagati ya bateri z'uruhererekane rw'ibice bitatu n'izifite ibisa n'ibi ...?
A: Voltage n'ubushobozi biratandukanye.Guhuza umurongo w'amashanyarazi byongera ingufu z'amashanyarazi, naho guhuza kuri parallel byongera ingufu z'amashanyarazi (ubushobozi)
1) Guhuza ibintu mu buryo bunyuranyije
Dufate ko voltage ya selile ya bateri ari 3.7V kandi ubushobozi bwayo ari 2.4Ah. Nyuma yo guhuza ibintu icyarimwe, voltage ya terminal ya sisitemu iracyari 3.7V, ariko ubushobozi bwayo buriyongera bukagera kuri 7.2Ah.
2) Guhuza urukurikirane
Dufate ko voltage ya selile ya bateri ari 3.7V kandi ubushobozi bwayo ari 2.4Ah. Nyuma yo guhuza umurongo, voltage ya nyuma ya sisitemu ni 11.1V, kandi ubushobozi bwayo ntibuhinduka.
Niba bateri ifite urukurikirane rutatu n'izindi ebyiri zihwanye, zose hamwe zikaba ari 6 18650, bateri ni 11.1V na 4.8Ah. Sedan ya Tesla Model-S ikoresha bateri za Panasonic 18650, naho bateri ya 85kWh ikenera bateri zigera ku 7.000.
Umwanzuro
Heltec izakomeza kuvugurura ubumenyi bw'ubumenyi buzwi ku bijyanyebateri za litiyumuNiba ubyifuza, ushobora kubyitondera. Muri icyo gihe, tuguha bateri za lithium nziza zo kugura no gutanga serivisi zihariye zijyanye n'ibyo ukeneye.
Heltec Energy ni umufatanyabikorwa wawe wizeye mu gukora bateri. Dufite intego yo gukora ubushakashatsi n'iterambere, hamwe n'ibikoresho byacu byinshi bya bateri, dutanga ibisubizo bihoraho kugira ngo duhuze n'ibyo uruganda rukeneye. Kwiyemeza kwacu gukora neza, ibisubizo bigezweho, n'ubufatanye bukomeye n'abakiriya bituma tuba amahitamo meza ku bakora bateri n'abatanga serivisi ku isi yose.
Niba ufite ikibazo cyangwa wifuza kumenya byinshi, ntutindiganye kugisubizatubwire.
