Ni igiki Busbars mu Bateri za Lithium?

Ivyuma gusa vy’umuringa canke aluminium bikorakoranya amazi mu ngingo ibihumbi n’ibihumbi maze ukabirungika ku nzira zibiri nini. Atabo iyo pack ntishobora gukora. Kubera ko bakoze nabi iyo pack overs, iratakaza urutonde, canke igafata umuriro.

Utugingo ngengabuzima tubanje guhurira mu bice bikoresheje imirongo ya nickel canke umugozi- Ibara ry’aluminium ipfutse. Modules hanyuma ubone urutonde- ruhujwe biciye mu bisi nyavyo. Ivyo bihimba bitatu vy’agaciro vy’agaciro uno musi:

Bisimbu y'ikiyaga

Ivyuma vyinshi vy’i 0.8–1,5 mm igipande c’umuringa gifise PET canke filime ya PI y’i PI iri hagati, ishushe- yashizweko kandi iragabanuka-. Hafi buri platform ya 800 V irazikoresha kubera ko indurance igabanuka munsi ya 20 nH. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, imodoka nyinshi z’abashinwa 800 V, zose zari zifise amababa.

Bitowari ishobora guhinduka

Ikirundo c’ibipapuro vy’umuringa vy’imiringa 0,1–0,3.3.3. Tesla yarazikoresheje mu bice vya mbere 3/Y, mu nyuma yarahindukiye ngo ibe iya laminate. Naho nyene ari ibisanzwe aho iyo pack igomba gugorana n’ivyo bita chassis.

Umubare ukeye

Smple 10×50 mm canke 10×100 mm imirongo y’umuringa ireshe uca ubona mu mapaki y’ibipfukisho ya BYD, inguvu nyinshi- imbere y’ibindi, n’ibintu vyinshi vy’ubudandaji vya LFP{5}}. Guteba kandi vyoroshe gukora imashini, ariko biramenagura imyobo y’amabuye y’agaciro inyuma y’ibihumbi bikeyi vy’ubushuhe.

Umuringa uri mu gipapuro c'ibati (ugukonjesha kavukire, igice c'imeza y'imeza, igice c'umubiri):2.0–2.2 A/mm2 ibandanyani umutekano utunganye.
5 mm × 30 mm bar=150 mm2 → 300–330 Igikoko gikomeza, 600–700 A ku 10–30 stursts ni ibisanzwe.
Abantu basubiramwo 1.6 A/mm2 ni ugukopa imeza z’uguhindura; imbere mu gipande umuyaga ni mwiza mu vy’ukuri.

Guboroga kwa Laser: mwami. Umuringa -kugira-kanda canke umuringa{{3}ba-aluminum (n'uguhindura nickel) bitanga < 0.03 mΩ ku ngingo.
Yashizweko: inguvu- Abahungu bakunda M10/M12 tin- Ivyuma vy’amazi + vya Belleville, 20–25 Nm. Serivisi yoroshe.
Ivyo gutera ivyatsi canke gutera ijwi ry’umuyagankuba: CATL n’ibindi bikeyi, si tarstream.

Xiaomi SU7 800 Ipaki: 6-lamer × 1 mm × 48 mm
BYD Ikimenyetso / Qin Plus DM-i: 10 mm × 80 mm umurongo ukomeye, ~350 A
Megapack 2 XL: 12 mm × 120 mm tin- imirongo y'imirongo, 1000 A ikomeza ku gice

90℃iguma ku ruhande rw’umuringa, 110–120 degrees - Ijambo ryemewe, hejuru ya degre 130, iyo filime itangura guhagarika umutima. Ivyinshi mu bipande vy’amapaki bikomeza NTC ku rubavu kandi BMS irabiraba nk’igisasu.

ISO 6469-3 – umutekano w'umuyagankuba

ISO 12405 – test spect

IEC 62660-3 – ubushobozi bwo gukora n'ubushobozi bwo gupakira

QC/T 1075 – EV y'abashinwa (niba igurishijwe mu Bushinwa)

UL 1973 canke UL 2580 bivanye n’isoko

Ivyo ni vyo. Ibindi vyose kandi noba ndiko ndasubiramwo ivyagezwe vy’amakuru.
