Dab tsi yog Busbars hauv Lithium roj teeb?

Tsuas yog cov khoom tuab ntawm tooj liab lossis txhuas uas sau tam sim no los ntawm ntau txhiab lub hlwb thiab xa tawm mus rau ob lub terminals loj. Yog tsis muaj lawv lub pob tsis tuaj yeem ua haujlwm. Nrog lawv ua tsis ncaj ncees lawm lub pob overheats, poob ntau yam, los yog catches hluav taws.

Cov xovtooj thawj zaug tau sib npaug mus rau hauv cov qauv siv cov nickel strips lossis xaim -bonded txhuas hlau. Modules ces tau series - txuas los ntawm cov busbars tiag. Peb lub ntsiab flavors dominate hnub no:

Laminated busbar

Ob peb txheej ntawm 0.8-1.5 mm tooj liab ntawv ci nrog nyias PET lossis PI zaj duab xis nyob nruab nrab, kub- nias thiab ntsws- qhwv. Yuav luag txhua 800 V platform siv lawv vim tias inductance poob qis dua 20 nH. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, feem ntau suav 800 V tsheb, tag nrho cov laminated.

Flexible busbar

Ib pawg ntawm 0.1-0.3 hli liab qab tooj liab foils welded tsuas yog ntawm qhov kawg, nruab nrab nyob twj ywm saj zawg zog. Tesla siv lawv ntawm cov qauv 3 / Y thaum ntxov, tom qab hloov mus rau laminated. Tseem muaj qhov uas cov pob yuav tsum sib tw nrog lub chassis.

Rigid bar

Tej yam yooj yim 10 × 50 mm los yog 10 × 100 mm milled tooj liab tuav koj tseem pom nyob rau hauv BYD Hniav packs, feem ntau lub zog- ntim ntim, thiab ntau LFP coj mus muag- tsheb packs. Pheej yig thiab yooj yim rau tshuab, tab sis lawv tawg nyob ib ncig ntawm lub qhov rooj tom qab ob peb txhiab thermal voj voog.

Tooj liab nyob rau hauv ib lub roj teeb pob (natural cooling, semi-enclosed):2.0-2.2 A / mm² txuas ntxivyog zoo kawg nkaus.
5 mm × 30 mm bar=150 mm² → 300–330 A nruam, 600–700 A rau 10–30 s tawg yog niaj hnub.
Cov neeg uas hais 1.6 A / mm² yog luam cov lus hloov pauv; hauv ib pob cov airflow yeej zoo dua.

Laser vuam: huab tais. Copper-rau-tooj liab lossis tooj liab-rau- txhuas (nrog nickel hloov shim) muab <0.03 mΩ ib leeg.
Bolted: zog-cov neeg khaws cia nyiam M10/M12 tin-plated bolts + Belleville washers, 20–25 Nm. Kev pabcuam yooj yim.
Kev sib txhuam do los yog sib nqus mem tes vuam: CATL thiab ob peb lwm yam, tsis yog qhov tseem ceeb.

2021-2023 Model 3/Y (Panasonic 2170): 4-txheej × 1 hli × 38 hli laminated ≈ 500 A nruam
2024 Qauv Y (LG 4680): 5-txheej × 1.2 hli × 42 hli
Xiaomi SU7 800 V pob: 6-txheej × 1 hli × 48 hli
BYD Foob / Qin Plus DM-i: 10 mm × 80 mm rigid bar, ~ 350 A
Megapack 2 XL: 12 mm × 120 mm tin -plated rigid tuav, 1000 A nruam ib theem

90℃txuas ntxiv rau ntawm qhov chaw tooj liab, 110-120℃luv luv- lub sijhawm siv tau, siab dua 130℃cov yeeb yaj kiab rwb thaiv tsev pib txhawj xeeb. Feem ntau cov pob ntawv lo NTCs ncaj qha rau ntawm lub tsheb npav thiab BMS saib nws zoo li tus hawk.

Zoo nkauj heev nws. Ib qho kev nthuav dav ntxiv thiab kuv tsuas yog rov hais dua cov ntaub ntawv.
