Marka la naqshadeynayo ama la ballaarinayo nidaamyada ku shaqeeya baytariga, su'aal caadi ah ayaa soo baxda: Laba baakidh oo batari isku dan ah ma lagu xidhi karaa si taxane ah? Jawaabta oo kooban waahaa, laakiin leh shuruud muhiim ah:danabku u adkeysan karo awoodda wareegga ilaalintawaa in si taxadar leh loo qiimeeyaa. Hoosta, waxaan ku sharxeynaa tafaasiisha farsamada iyo taxaddarrada si loo xaqiijiyo hawlgal ammaan ah oo la isku halayn karo.
Fahamka Xadka: Ilaalinta Dulqaadka Korantada ee Wareegga
Xirmooyinka baytariyada lithium waxaa sida caadiga ah lagu qalabeeyay Ilaalinta Wareegga Ilaalinta (PCB) si ay uga hortagto dallacaadda xad-dhaafka ah, shubidda xad-dhaafka ah, iyo wareegyada gaaban. Halbeegga muhiimka ah ee PCB-gan ayaa ahdanab u adkaysta qiimaynta MOSFETs(qalabka elektarooniga ah ee xakameynaya socodka hadda).
Tusaale:
Tusaale ahaan u soo qaado laba xidhmo oo batari LiFePO4 ah oo 4 unug ah. Baakad kastaa waxay leedahay danab buuxa oo ah 14.6V (3.65V unug kasta). Haddii si taxane ah loogu xidho, danabkooda isku dhafan ayaa noqda29.2V. PCB-ga ilaalinta batteriga caadiga ah ee 12V waxaa badanaa loogu talagalay MOSFETs35-40V. Xaaladdan oo kale, wadarta tamarta (29.2V) waxay ku dhacdaa xadka badbaadada ah, taas oo u oggolaanaysa baytariyadu inay si sax ah u shaqeeyaan si taxane ah.
Khatarta Xadka Gudbinta:
Si kastaba ha noqotee, haddii aad isku xirto afar xirmo oo taxane ah, wadarta korontadu waxay ka badnaan doontaa 58.4V — aad uga fog dulqaadka 35-40V ee PCB-yada caadiga ah. Tani waxay abuurtaa khatar qarsoon:
Sayniska ka dambeeya Khatarta
Marka baytariyadu si isdaba joog ah isugu xidhan yihiin, danabkoodu way isku daraan, laakiin wareegyada ilaalintu waxay u shaqeeyaan si madaxbannaan. Xaaladaha caadiga ah, korantada la isku daray waxay awood u siineysaa culeyska (tusaale, aaladda 48V) iyadoon wax dhibaato ah jirin. Si kastaba ha ahaatee, haddiihal baakidh oo batari ah ayaa kicinaya ilaalinta(tusaale, daadad xad-dhaaf ah ama qulqulka badan awgeed), MOSFET-yadeeda waxay ka jarayaan xirmada wareegga.
Halkaa marka ay marayso, tamarta buuxda ee baytariyada hadhay ee taxanaha ah ayaa lagu dabaqayaa MOSFET-yada go'an. Tusaale ahaan, marka lagu rakibo afar xidhmo, PCB-ga go'ay ayaa wajihi doona ku dhawaad58.4V-oo ka sarreeya 35-40V. MOSFET-yada ayaa markaa laga yaabaa inay ku guuldareystaan sababtoo ahburburka danab, si joogto ah u curyaamiya wareegga ilaalinta iyo ka tagista batteriga mid u nugul khataraha mustaqbalka.
Xalka Xidhiidhada Taxanaha Badbaado leh
Si looga fogaado khatarahan, raac tilmaamahan:
1.Hubi Tilmaamaha Soo-saareha:
Had iyo jeer xaqiiji in ilaalinta batterigaaga PCB lagu qiimeeyay codsiyo taxane ah. Qaar ka mid ah PCB-yada si cad ayaa loogu talagalay in lagu xakameeyo tamarta sare ee isku xidhka baakadaha badan.
2.PCB-yada Voltage-sare ee gaarka ah:
Mashaariicda u baahan baytari badan oo taxane ah (tusaale, kaydinta cadceedda ama nidaamyada EV), dooro wareegyada ilaalinta leh MOSFET-ga korantada sare ee la habeeyey. Kuwan waxaa loo habayn karaa si ay u adkaystaan wadarta tamarta ee habayntaada taxanaha ah.
3.Nakhshad Isku Dheeli Tiran:
Hubi in dhammaan xidhmooyinka batteriga ee taxanaha ahi ay isku dhigmaan awoodda, da'da, iyo caafimaadka si loo yareeyo khatarta kicinta aan sinnayn ee hababka ilaalinta.
Fikirka ugu dambeeya
Iyadoo isku xidhka baytariyada isku voltajka ee taxanaha ah ay farsamo ahaan macquul tahay, caqabada runta ahi waxay ku jirtaa hubinta inWareegga ilaalinta ayaa xamili kara culeyska korantada ee isbiirsaday. Adiga oo kala hormarinaya qeexida qaybaha iyo naqshadaynta firfircoonida leh, waxaad si badbaado leh u cabbiri kartaa nidaamka batterigaaga codsiyada korantada sare.
