Waa maxay Basbaarsyada ku jira baytariyada Lithium?
Qaybo qaro weyn oo naxaas ah ama aluminium ah oo hadda ka soo ururiya kumanaan unug oo u dira labada terminal ee waaweyn. Iyaga la'aantood baakidhku ma shaqayn karo. Iyaga oo khalad loo sameeyay baakidhku wuu kululaaday, luminayaa, ama dab qabsaday.
Sida dhab ahaantii loo isticmaalo
Unugyadu marka hore waxay isbarbardhigaan cutubyada iyagoo isticmaalaya xariijimaha nikkel ama silig - fiilooyin aluminium isku xidhan. Modules ayaa markaa helaya taxane -ku xidhma baska dhabta ah. Saddexda dhadhan ee ugu muhiimsan ayaa maanta xukuma:
baska la dhejiyay
Dhowr lakab oo ah 0.8-1.5 mm bireed naxaas ah oo leh PET dhuuban ama filim PI ah oo u dhexeeya, kulul{2}}lagu riixay oo la yareeyey-oo la duubay. Ku dhawaad goob kasta oo 800 V ah ayaa isticmaasha iyaga sababtoo ah inductance waxay hoos uga dhacdaa 20 nH. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, inta badan shiinaha ee 800 V baabuurta, dhamaantood waa la dahaadhay.
baska dabacsan
Raso ah 0.1-0.3 mm foils naxaas ah oo qaawan oo lagu alxanayo darafyada oo kaliya, dhexda ayaa u dabacsanaan doonta. Tesla waxay ku isticmaashay baakadaha Model 3/Y hore, ka dib waxay u beddeleen dahaadh. Wali waa caadi halka baakadu ay tahay in ay ku maroojiso chassis-ka.
Baar adag
Fudud 10 × 50 mm ama 10 × 100 mm baararka shiida ee naxaasta ah oo aad wali ku aragto xidhmooyinka BYD Blade, tamarta ugu badan{4}} weelasha kaydinta tamarta, iyo ganacsiyo badan oo LFP{5} ah oo baabuurta ah. Qalab jaban oo si sahlan loo makiinado, laakiin waxay dilaacaan hareeraha godad bolteedka ka dib dhowr kun oo wareegyo kulayleed ah.
Dhabta ah- cufnaanta hadda aduunka ee aan isticmaalo
Copper batteriga ku jira (qaboojin dabiiciga ah, badh-kuxiran):2.0–2.2 A/mm² joogto ahsi fiican ayaa ammaan ah.
5 mm × 30 mm bar=150 mm² → 300–330 A joogto ah, 600–700 A ee 10–30s dilaacyadu waa joogto.
Dadka soo xiganaya 1.6 A/mm² waxay koobiyanayaan miisaska beddelka; Baakidhka dhexdiisa socodka hawadu waa ka fiican yahay.
Hababka isku xirka aan arko maalin kasta
- alxanka Laser: boqor. Naxaasta -ilaa{2}}maxaasta ama naxaasta-ilaa{4}}aluminium (oo leh shimka wareejinta nikkel) waxa uu siinayaa <0.03 mΩ labbo kasta.
- La xidhay: tamarta{0}}Ragga kaydinta waxay jecel yihiin daasadda M10/M12 - boolal dahaaran + Wershadaha Belleville, 20–25 Nm. Adeeg fudud.
- Walaaqda jeexjeexa ama alxanka garaaca birlabeedka: CATL iyo kuwa kale oo yar, oo aan ahayn mid guud weli.
Nambarada baakadaha aan shakhsi ahaan u jeexjeexay
- 2021–2023 Qaabka 3/Y (Panasonic 2170): 4-lakab × 1 mm × 38 mm dahaaran ≈ 500 A joogto ah
- 2024 Model Y (LG 4680): 5-lakab × 1.2 mm × 42 mm
- Xirmadan Xiaomi SU{0} V: 6-lakab × 1 mm × 48 mm
- BYD Seal / Qin Plus DM -i: 10 mm × 80 mm baararka adag, ~350 A
- Megapack 2 XL: 12 mm × 120 mm daasad - baararka dahaaran ee adag, 1000 A joogto ah waji kasta
Heerkulka ayaa xaddidaya qof walba ixtiraam
90 darajo oo ku sii socota dusha naxaasta, 110-120 digrii gaaban -muddada waa la aqbali karaa, in ka badan 130 darajo filimka dahaarka ayaa bilaabaya walwal. Baakadaha intooda badani waxay si toos ah ugu dhejiyaan NTC-yada baska waxayna BMS u daawataa sida cawska.
Heerarka dhab ahaantii waa inaan buuxinaa
TS EN ISO 6469-3 Badbaadada korantada
TS EN ISO 12405 - Baakadka tijaabada
IEC 62660-3 - Unugyada iyo xirmooyinka waxqabadka / badbaadada

Taasi waa wax aad u qurux badan. Faahfaahin dheeraad ah iyo waxaan kaliya ku celin lahaa xaashida xogta.
