Chiyambi:
Nkhani yayikulu pakukonza batire ndi kukulitsa kwa batire ya lithiamu ndi ngati ma seti awiri kapena angapo a batri la lithiamu amatha kulumikizidwa mwachindunji mndandanda kapena mofananira. Njira zolumikizirana zolakwika sizingangopangitsa kuti batire ichepe, komanso zitha kuyambitsa zoopsa zachitetezo monga mabwalo amfupi ndi kutentha kwambiri. Kenako, tidzasanthula mwatsatanetsatane njira zolondola komanso zodzitetezera zolumikizira mapaketi a batri ya lithiamu kuchokera kumawonekedwe onse ofanana ndi mndandanda. Kenako, ife kusanthula mwatsatanetsatane njira zolondola ndi zodzitetezera kulumikiza lithiamu batire mapaketi onse kufanana ndi mndandanda amaonera, pamodzi ndi ntchitokuyesa kwa batri ndi zida zokonzera.
Kulumikizana kofanana kwa paketi ya batri ya lithiamu: kutsindika kofanana pamikhalidwe ndi chitetezo
Kulumikizana kofananira kwa mapaketi a batri a lithiamu kumatha kugawidwa m'magawo awiri, pachimake chomwe chimakhala ngati magawo a batri amagwirizana komanso ngati njira zodzitetezera zatengedwa. Poweruza magawo a batire paketi, lithiamuchoyesa batireimatha kuyeza molondola deta monga magetsi ndi kukana kwamkati, kupereka maziko asayansi a dongosolo lolumikizira
(1) Kulumikizana kwachindunji kofananira pamene magawo amagwirizana
Pamene voteji, mphamvu, kukana mkati, chitsanzo selo ndi zina specifications awiri lifiyamu batire mapaketi ali chimodzimodzi, ntchito kufanana akhoza mwachindunji ikuchitika. Mwachitsanzo, ntchito lifiyamu batire Tester kudziwa magulu awiri a lifiyamu batire mapaketi ndi yemweyo 4-mndandanda dongosolo ndi voteji mwadzina 12V, pamene mokwanira mlandu ndi voteji chomwecho, kulumikiza mzati awo okwana zabwino mzati okwana zabwino mzati ndi okwana zoipa mzati kumaliza kugwirizana kufanana. Tiyenera kutsindika kuti batire iliyonse iyenera kukhala ndi bolodi yodzitetezera kuti iwonetsetse kuti batire ikuchulukirachulukira, kutulutsa, komanso chitetezo chanthawi yochepa. Komanso, pambuyo kugwirizana anamaliza, m`pofunika kugwiritsa ntchito lithiamuchoyesa batirekuti muyang'anenso magawo onse kuti muwonetsetse kugwira ntchito kwa batri yolumikizidwa yofananira. ku
(2) Chiwembu chofananira pamene magawo sakugwirizana
Mu ndondomeko yeniyeni yokonza, ndizofala kukumana ndi mapaketi a batri opangidwa ndi magulu osiyanasiyana a maselo, ngakhale mphamvu yamagetsi yofanana ndi yofanana (monga 12V), pali kusiyana kwa mphamvu (50Ah ndi 60Ah) ndi kukana kwamkati. Pankhaniyi, kugwirizana mwachindunji kufanana kudzabweretsa zoopsa zazikulu - pamene ma voltages a magulu awiri a batri ali osiyana (monga 14V ndi 12V), gulu la batire lapamwamba kwambiri lidzalipiritsa gulu la batri lotsika kwambiri. Malinga ndi Lamulo la Ohm, ngati kukana kwamkati kwa batire yotsika mphamvu ndi 2 Ω, kuyitanitsa komweko kumatha kufika ku 1000A, komwe kungapangitse batire kutentha, kuphulika, kapena kugwira moto mosavuta. ku
Kuti muthane ndi vutoli, zida zotetezera zofanana ziyenera kuwonjezeredwa:
Sankhani bolodi lodzitchinjiriza lomwe lili ndi ntchito zotsekereza zomwe zamangidwa: Ma board ena apamwamba kwambiri amakhala ndi malire apakali pano, omwe amatha kuchepetsa kuyitanitsa komwe kumayenderana ndi chitetezo. Posankha bolodi loteteza, lithiamuchipangizo chokonzera batriangagwiritsidwe ntchito kufufuza ngati ntchito yake ndi yachibadwa. ku
Kuyika gawo lochepetsera lakunja lofananira: Ngati bolodi lodzitchinjiriza ilibe ntchitoyi, gawo lowonjezera laukadaulo laukadaulo litha kukhazikitsidwa kuti liziwongolera zomwe zikuchitika pamlingo woyenera ndikuwonetsetsa kulumikizana kotetezeka. Pambuyo kukhazikitsa gawo lochepetsera pano, ndikofunikira kugwiritsa ntchito choyesa cha lithiamu batire kuti muwone zomwe zasintha ndikuwonetsetsa kuti gawoli likuyenda bwino.
Kulumikizana kwa mndandanda wa paketi ya batri ya lithiamu: zofunika kwambiri komanso makonda
Poyerekeza ndi kulumikizana kofananira, kulumikizana kwa batire la lithiamu kumafunikira zofunikira zolimba za paketi ya batri. Mukalumikizidwa mndandanda, zitha kufananizidwa ndi kusonkhana kwa maselo a batri amkati mu paketi ya batri, yomwe imafunikira magawo osagwirizana kwambiri monga voteji, mphamvu, kukana kwamkati, komanso kudzipatula pamlingo pakati pa mapaketi awiri a batri. Kupanda kutero, kugawa kwamagetsi kosagwirizana kumatha kuchitika, kumathandizira kukalamba kwa mapaketi a batri osachita bwino. Posankha batire yoyenera mapaketi, lithiamuzoyesa batireimatha kuzindikira mwachangu komanso molondola magawo osiyanasiyana, ndikuwongolera magwiridwe antchito. ku
Komanso, okwana voteji pambuyo mndandanda kugwirizana ndi kuchuluka kwa voteji gulu limodzi (monga seti awiri a 12V mabatire olumikizidwa mu mndandanda kwa 24V), amene amaika zofunika apamwamba pa kupirira voteji mtengo wa Mos chubu mu bolodi chitetezo. Ma board odzitchinjiriza wamba nthawi zambiri amakhala oyenera magulu amagetsi amodzi okha. Mukagwiritsidwa ntchito motsatizana, nthawi zambiri pamafunika kusintha ma board oteteza ma voltage apamwamba kapena kusankha makina owongolera ma batire (BMS) omwe amathandizira zingwe zingapo kuti zitsimikizire chitetezo ndi kukhazikika kwa mndandanda womwe umalumikizidwa ndi batire panthawi yolipiritsa ndi kutulutsa. Chipangizo chokonzera batire la lithiamu chimatha kuwongolera ndikuwongolera zovuta pama board otetezedwa ndi BMS kuti zitsimikizire kuti zimagwira ntchito bwino.
Malangizo Otetezeka ndi Malingaliro Othandiza
Kulumikizana kofananira kotsatira sikuloledwa: mapaketi a batri a lithiamu amitundu yosiyanasiyana ndi ma batchi saloledwa kulumikizidwa mwachindunji popanda chithandizo chifukwa cha kusiyana kwa mawonekedwe a batri ndi machitidwe. ku
Kuyang'anitsitsa ndi kukonza nthawi zonse: Dongosolo lofananira liyenera kuyang'ana mphamvu ya batri pakiti mwezi uliwonse, ndipo ngati kusiyana kupitilira 0.3V, kumafunika kulipiritsa padera kuti kulinganize; Ndikofunikira kuti muzitha kuwongolera dongosolo la mndandanda kudzera pa BMS kotala lililonse. ku
Sankhani zipangizo zapamwamba: M'pofunika kugwiritsa ntchito matabwa otetezera ndi BMS ovomerezeka ndi UN38.3, CE, ndi zina zotero. Waya wolumikizira uyenera kusankhidwa ndi waya woyenerera molingana ndi katundu wamakono kuti asatenthedwe chifukwa cha kutaya waya. ku
Kugwira ntchito kofananira kwa mapaketi a batri a lithiamu kuyenera kukhazikitsidwa pachitetezo, kuwongolera mosasinthasintha kwa magawo a batire, komanso kugwirizana ndi zida zoteteza akatswiri. Kudziwa mfundo zazikuluzikulu sikungangowonjezera kukonzanso kwa batri, komanso kuonetsetsa kuti ma batire a lithiamu akugwira ntchito kwanthawi yayitali.
