Busbars mu Bateri za Litiyumu Ni Iki?
Ibipande gusa vy’umuringa canke vy’aluminiyumu bikomeye bikorakoranya amashanyarazi ava mu bice ibihumbi n’ibihumbi maze bikayohereza hanze ku bibanza bibiri bininibinini vy’amashanyarazi. Iyo ata bo iyo pack ntishobora gukora. Iyo bakoze nabi, iyo paki irashuha cane, igatakaza aho ishobora gushika, canke igafata umuriro.
Uko mu vy'ukuri zikoreshwa .
Ivyuma bibanza guhurizwa hamwe mu bice bikoresheje imirongo ya nickel canke intsinga-zifatanye n'intsinga z'aluminium. Ivyiyumviro rero bica bifata urutonde-bihujwe biciye mu bice vy'ukuri. Hari ibintu bitatu nyamukuru biganzwa muri iki gihe:
Umugozi wa bisi
Ivyumba vyinshi vy’umuringa w’iminota 0,8–1,5 bifise igipande c’umuringa c’agaciro ka PET canke PI hagati, bishushe-bikandagijwe kandi bipfutse-bipfutse. Hafi buri platforme ya 800 V irazikoresha kuko inductance igabanuka munsi ya 20 nH. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, imodoka nyinshi z’abashinwa zifise ubushobozi bwa 800 V, zose zifise amabara.
Umugozi wa bisi ushobora guhinduka
Igitero c’ibipande vy’umuringa vy’uburebure bwa 0,1–0,3 mm bifatanye gusa ku mpera, hagati biguma bihinduka. Tesla yarazikoresheje ku mapaki ya mbere ya Model 3/Y, mu nyuma zihindurwa zija ku mapaki ya laminated. Naho nyene birasanzwe aho ipaki itegerezwa kugobeka n’igice c’umubiri.
Umugozi ukomeye
Ivyuma vy’umuringa vyoroshe vy’uburebure bwa 10×50 mm canke 10×100 mm uracabona mu mapaki ya BYD Blade, mu bikoresho vyinshi vyo kubikamwo inguvu-, no mu mapaki menshi y’ibinyabiziga vy’ubudandaji vya LFP-. Birahenda kandi biroroshe gukoreshwa n’imashini, ariko birasaduka hirya no hino y’ibinogo vy’amabuye inyuma y’ibihumbi bikeyi vy’ingendo z’ubushuhe.
Uburemere bw'isi nyayo-nkoresha
Umuringa uri muri bateri (ugukonjesha kamere, igice-kifunze):2.0–2.2 A/mm2 ikomezani umutekano utunganye.
5 mm × 30 mm bar=150 mm2 → 300–330 A ikomeza, 600–700 A ku biturika vy’amasegonda 10–30 ni ibisanzwe.
Abantu basubiramwo 1,6 A/mm2 bariko barakopa ameza y’ibikoresho vy’uguhindura; imbere mu paki umuyaga mu vy’ukuri urarushiriza kuba mwiza.
Uburyo bwo guhuza mbona buri musi
- Laser gusudira: umwami. Umuringa-ku-umuringa canke umuringa-ku-aluminiyumu (ifise igice c’uguhindura nickel) itanga < 0.03 mΩ ku nsangangura.
- Ivyuma: ingufu{0}}ububiko bw’abahungu bakunda M10/M12 ivyuma vy’amabati + ivyuma vy’amabuye vy’i Belleville, 20–25 Nm. Servisi yoroshe.
- Ivyuma vy’ugutera ivyatsi canke ivy’ugutera ivyatsi: CATL n’ibindi bikeyi, ntibiramenyekana cane.
Igitigiri kivuye mu mapaki jewe ubwanje nasambuye
- 2021–2023 Igishushanyo 3/Y (Panasonic 2170): 4-ibipande × 1 milimetero × 38 milimetero ≈ 500 A ikomeza
- 2024 Igishushanyo Y (LG 4680): 5-imirongo × 1.2 milimetero × 42 milimetero
- Xiaomi SU 7 800 V: 6-imirongo × 1 mm × 48 mm
- Ikidodo ca BYD / Qin Yongeyeko DM{0}}i: 10 mm × 80 mm umurongo ukomeye, ~350 A
- Megapack 2 XL: 12 mm × 120 mm y'ibiti bikomeye vy'ibiti, 1000 A bikomeza ku ntambwe
Ubushuhe buragabanya umuntu wese yubaha
90℃zikomeza ku ruhande rw’umuringa, 110–120℃igihe gito-ni co cemewe, hejuru ya 130℃film y’ivyuma itangura kwiganyira. Amapaki menshi afatanya NTCs directement ku busbar na BMS ikabiraba nk’inzoka.
Ivyiyumviro mu vy'ukuri dutegerezwa gushitsa
ISO 6469-3 – umutekano w'umuyagankuba
ISO 12405 – igerageza ry'ibipapuro
IEC 62660-3 – ubushobozi bw'ingingo n'umutekano
QC/T 1075 – Ivyerekeye EV y’Abashinwa (niba bagurisha mu Bushinwa)
UL 1973 canke UL 2580 bivanye n'isoko .
Ivyo ni vyo vyiza cane. Ibindi vyose kandi noba ndiko ndasubiramwo amakuru.
