Busbars niki muri Batteri ya Litiyumu?

Gusa ibice byinshi byumuringa cyangwa aluminiyumu ikusanya amashanyarazi kuva mu bihumbi ibihumbi hanyuma ikohereza kuri terefone ebyiri nini. Bitabaye ibyo, ipaki ntishobora gukora. Hamwe nabo bakoze nabi paki irashyuha, itakaza intera, cyangwa ifata umuriro.

Ingirabuzimafatizo zabanje kugereranywa na module ukoresheje imirongo ya nikel cyangwa insinga - insinga za aluminiyumu. Module noneho ibone urukurikirane - ihujwe na busbars nyayo. Uburyohe butatu bwiganje muri iki gihe:

Ibice byinshi bya 0.8-1.5 mm yumuringa wumuringa hamwe na firime ya PET cyangwa PI hagati, ashyushye - ukanda kandi ugabanuka - bipfunyitse. Hafi ya 800 V platform yose irabikoresha kuko inductance igabanuka munsi ya 20 nH. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, imodoka nyinshi zo mu Bushinwa 800 V, zose zamuritswe.

Ikirindiro cya mm 0.1–0.3 mm yumuringa wumuringa wambaye ubusa wasuditswe gusa kumpera, hagati iguma ihindagurika. Tesla yabikoresheje kumapaki ya Model 3 / Y kare, nyuma ihinduka kuri laminated. Biracyasanzwe aho paki igomba kugoreka hamwe na chassis.

Rigid bar

Byoroheje 10 × 50 mm cyangwa 10 × 100 mm byasya umuringa wumuringa uracyabona mumapaki ya BYD Blade, ingufu nyinshi - ibikoresho byo kubika, hamwe nubucuruzi bwinshi bwa LFP -. Guhendutse kandi byoroshye kumashini, ariko zisenyuka hafi yumwobo nyuma yibihumbi bike byumuriro.

Umuringa mu gipaki cya batiri (gukonjesha bisanzwe, igice - gifunze):2.0-22.2 A / mm² ikomezani umutekano rwose.
5 mm × 30 mm bar bar=150 mm² → 300–330 Gukomeza, 600-700 A kuri 10-30 s guturika ni ibintu bisanzwe.
Abantu bavuze 1.6 A / mm² bakopera ameza ya switchgear; imbere mumupaki umwuka mwiza mubyukuri nibyiza.

Gusudira Laser: umwami. Umuringa - kugeza - umuringa cyangwa umuringa - kugeza - aluminium (hamwe na shimike ya nikel) itanga <0.03 mΩ kuri buri rugingo.
Bolted: ingufu - abasore babika bakunda amabati M10 / M12 - yashizwemo ibisate + Bamesa Belleville, 20-25 Nm. Serivisi yoroshye.
Kuvangavanga gukurura cyangwa magnetiki pulse gusudira: CATL nabandi bake, ntabwo ari rusange.

2021–2023 Icyitegererezo 3 / Y (Panasonic 2170): igorofa 4 × 1 mm × 38 mm yamurikiwe ≈ 500 Ikomeza
2024 Model Y (LG 4680): 5-layer × 1,2 mm × 42 mm
Xiaomi SU 7 800 V ipaki: 6-layer × 1 mm × 48 mm
Ikidodo cya BYD / Qin Plus DM - i: 10 mm × 80 mm akabari gakomeye, ~ 350 A
Megapack 2 XL: 12 mm × 120 mm tin - zometseho utubari, 1000 Gukomeza kuri buri cyiciro

Impamyabumenyi 90 ikomeza hejuru yumuringa, dogere 110-120 ngufi - mvugo iremewe, hejuru ya dogere 130 firime ya insulation itangira guhangayika. Amapaki menshi ashyira NTCs kuri bisi hanyuma BMS ikayireba nkigisimba.

ISO 6469-3 - umutekano w'amashanyarazi

ISO 12405 - gupakira ibizamini

IEC 62660-3 - selile na pack imikorere / umutekano

QC / T 1075 - Ubushinwa bwa pack pack (niba igurishwa mubushinwa)

UL 1973 cyangwa UL 2580 ukurikije isoko

Nibyo rwose. Ibisobanuro birambuye kandi ndabisubiramo gusa.
