Intangiriro:
Uduce dukoresha ingufu z'amashanyarazi twagiye tuba ubwoko bw'ibicuruzwa byitabwaho cyane. Uduce dukoresha ingufu z'amashanyarazi ni ubwoko bw'uduce dukoresha ingufu z'amashanyarazi dukoreshwa mu kumenya imiterere itandukanye y'ikosa muri bateri z'ingirabuzima fatizo imwe n'izikoresha izindi ngirabuzima fatizo nyinshi. Muri sisitemu za bateri zo muri iki gihe, imiterere ya bateri za lithiamu-iyoni ikwiriye cyane sisitemu z'ikoranabuhanga zigendanwa, arikobateri za litiyumugukenera gukora mu buryo bukurikije imipaka yagenwe, hibandwa ku mikorere n'umutekano. Kubwibyo, kurinda bateri za lithium-ion ni ngombwa kandi ni ingenzi. Gukoresha imirimo itandukanye yo kurinda bateri ni ukwirinda ko habaho ibibazo nko gusohora OCD ikabije no gushyuha cyane OT, no kongera umutekano w'abateri.
Sisitemu yo gucunga batiri yashyizeho ikoranabuhanga ryo kuringaniza
Ubwa mbere, reka tuvuge ku kibazo gikunze kugaragara ku mapaki ya bateri, imiterere ihamye. Nyuma y’uko uturemangingo duto dukoze paki ya bateri ya lithium, ubushyuhe bushobora guhinduka ndetse n’ibibazo bitandukanye. Iki ni ikibazo giterwa no kudahuza kwa paki ya bateri ya lithium. Uturemangingo duto tugize paki ya bateri ya lithium ntabwo duhuza mu bushobozi, gusharija, no gusohora umuriro, kandi "ingaruka za barrel" zituma uturemangingo duto dufite imiterere mibi bigira ingaruka ku mikorere rusange ya paki ya bateri ya lithium yose.
Ikoranabuhanga ryo kuringaniza bateri ya lithiamu rizwi nk'uburyo bwiza bwo gukemura imiterere y'amapaki ya bateri ya lithiamu. Kuringaniza ni uguhindura voltage y'igihe nyacyo ya bateri zifite ubushobozi butandukanye binyuze mu guhindura ingufu z'amashanyarazi. Uko ubushobozi bwo kuringaniza burushaho gukomera, niko ubushobozi bwo gukumira ikwirakwira ry'ingufu no gukumira ubushyuhe bukabije, kandi niko ubushobozi bwo guhuza n'uburyopaki ya bateri ya lithiamu.
Ibi bitandukanye n'uburyo bworoshye bwo kurinda bukoresha ibikoresho. Uburinzi bwa bateri ya lithium bushobora kuba uburinzi bw'ibanze bwa overvoltage cyangwa uburinzi buhanitse bushobora gusubiza ubudashyuha, ikibazo cy'ubushyuhe cyangwa ikibazo cy'amashanyarazi. Muri rusange, IC yo gucunga bateri ku rwego rwa monitor ya bateri ya lithium na gauge ya lisansi ishobora gutanga imikorere yo kuringaniza bateri ya lithium. Monitor ya bateri ya lithium itanga imikorere yo kuringaniza bateri ya lithium kandi ikubiyemo imikorere yo kurinda bateri ya IC ifite ubushobozi bwo kuyitunganya cyane. Igipimo cya lisansi gifite urwego rwo hejuru rwo guhuza, harimo imikorere ya monitor ya bateri ya lithium, kandi ihuza algorithms zo kugenzura zihanitse hakurikijwe ishingiro ryazo.
Ariko, zimwe muri IC zirinda bateri ya lithium ubu nazo zirimo imikorere yo kuringaniza bateri ya lithium binyuze muri FET zihujwe, zishobora gusohora bateri zifite voltage nyinshi mu gihe cyo gusharija no kugumana bateri zifite voltage nke mu buryo bukurikiranye, bityo zigahuzapaki ya bateri ya lithiamuUretse gushyira mu bikorwa imikorere yuzuye y’uburinzi bw’amashanyarazi, ubushyuhe n’ubushyuhe, ibyuma bikingira bateri birimo gutangira gushyiraho imikorere yo kuringaniza kugira ngo bihuze n’ibyo bateri nyinshi zikeneye mu kurinda.
Kuva ku burinzi bw'ibanze kugeza ku burinzi bw'ibanze
Kuva ku burinzi bw'ibanze kugeza ku burinzi bw'ibanze
Uburinzi bw'ibanze ni uburinzi bw'amashanyarazi arenze urugero. Ama-IC yose yo kurinda bateri ya lithium atanga uburinzi bw'amashanyarazi arenze urugero hakurikijwe urwego rw'uburinzi butandukanye. Kuri iyi ngingo, amwe atanga uburinzi bw'amashanyarazi arenze urugero hamwe n'amashanyarazi arenze urugero, andi atanga uburinzi bw'amashanyarazi arenze urugero hamwe n'amashanyarazi arenze urugero hamwe n'uburinzi bw'ubushyuhe bwinshi. Kuri zimwe mu paki za bateri za lithium zifite uturemangingo twinshi, ubu burinzi ntibuhagije kugira ngo buhuze n'ibyo paki ya bateri ya lithium ikeneye. Muri iki gihe, hakenewe IC yo kurinda bateri ya lithium ifite imikorere yo guhuza bateri ya lithium.
Ubu burinzi bwa IC bugenewe uburinzi bw'ibanze, bugenzura uburyo bwo gushyushya no gusohora FET kugira ngo busubize ubwoko butandukanye bw'uburinzi bw'amakosa. Uku kuringaniza gushobora gukemura ikibazo cy'ubushyuhe buva mu kirere.paki ya bateri ya lithiamuneza cyane. Ubushyuhe bwinshi bukabije muri bateri imwe ya lithium buzangiza switch ya bateri ya lithium hamwe na resistor. Kugereranya bateri ya lithium bituma buri bateri ya lithium idakora neza muri bateri ya lithium uburinganire bungana n’ubw’izindi bateri zidakora neza, bigabanya ibyago byo guhumeka k’ubushyuhe.
Kuri ubu, hari uburyo bubiri bwo kugera ku kuringaniza bateri za lithiamu: kuringaniza imikorere n'kuringaniza ibintu bidakoreshejwe. Kuringaniza imikorere ni ugukoresha ingufu cyangwa gusharija kuva kuri bateri zifite voltage nyinshi/high-SOC kugera kuri bateri zifite SOC nke. Kuringaniza imikorere ni ugukoresha resistor kugira ngo ukoreshe ingufu za bateri zifite voltage nyinshi cyangwa charge nyinshi kugira ngo ugere ku ntego yo kugabanya icyuho kiri hagati ya bateri zitandukanye. Kuringaniza imikorere bidakoreshejwe bigabanya ingufu nyinshi n'ingaruka z'ubushyuhe. Mu kugereranya, kuringaniza imikorere ni ingirakamaro cyane, ariko uburyo bwo kugenzura imikorere buragoye cyane.
Kuva ku burinzi bw'ibanze kugeza ku burinzi bw'ibanze, sisitemu ya bateri ya lithium igomba gushyirwaho monitor ya bateri ya lithium cyangwa lisansi kugira ngo igere ku burinzi bw'ibanze. Nubwo uburinzi bw'ibanze bushobora gushyira mu bikorwa algorithme z'ubwenge zo kuringaniza bateri nta kugenzura MCU, uburinzi bw'ibanze bugomba kohereza voltage ya bateri ya lithium n'amashanyarazi kuri MCU kugira ngo hafatwe ibyemezo ku rwego rwa sisitemu. Monitors za bateri ya lithium cyangwa lisansi zipima muri rusange zifite imikorere yo kuringaniza bateri.
Umwanzuro
Uretse bateri cyangwa ibyuma bipima lisansi bitanga imikorere yo kuringaniza bateri, ibyuma bikingira bitanga uburinzi bw'ibanze ntibikigarukira gusa ku burinzi bw'ibanze nko gushyuha cyane. Uko ikoreshwa ry'uturemangingo twinshi rigenda ryiyongerabateri za litiyumu, bateri nini zifite ubushobozi bwo kuzirinda zizaba zifite ibisabwa byinshi kandi biri hejuru, kandi gushyiraho uburyo bwo kuzigama ni ngombwa cyane.
Kuringaniza ibintu ni nko kubungabunga. Buri shariji n'isohoka ry'amashanyarazi bizagira amafaranga make yo kuringaniza kugira ngo bihuze itandukaniro riri hagati ya bateri. Ariko, niba bateri cyangwa bateri ubwayo ifite inenge mu bwiza, uburinzi n'uburinganire ntibishobora kongera ubwiza bwa bateri, kandi si ingenzi ku isi yose.
Niba ufite ikibazo cyangwa wifuza kumenya byinshi, ntutindiganye kugisubizatubwire.
