Lithium Batteri ni hta gara hku rai nga a ta?

Dai hpang, wan hku law ai cell ni kaw na current hpe shinggyin la nna, terminal kaba lahkawng de sa dat ai copper (sh) aluminum ni hpe sha, n-gun ja ai. Shanhte n lawm yang pack gaw n mai galaw ai. Shanhte galaw ngut ai hte pack gaw grai katsi ai, range sum mat ai, wan n-gun n rawng mat ai.

Teng sha gara hku jai lang ai .

Cell ni hpe shawng nnan e nickel strips (sh) wire{0}}}} lapran na aluminum wire ni hpe lang nna module ni hku nna bung ai. Dai hpang Modules ni gaw, busbar tengman ai hku nna, series- matut mahkai ai lam lu la ai. Dai ni aten hta madung nsam masum gaw uphkang nga ai:

Laminate galaw ai busbar

0.8–1.5 mm magri mang n-gun law law hpe n-gun n rawng ai PET (sh) PI film ni hte lapran, katsi ai- n-gun jaw ai hte shrink{3}} n-gun rawng ai. V platform 800 daram gaw 20 nH a lawu de inductance hkrat wa ai majaw lang ai. Porsche Taycan, Hyundai Ioniq 5/6, Kia EV6, Miwa V mawdaw law malawng, yawng hpe laminate galaw da ai.

N kaja ai busbar

0.1–0.3 mm n rawng ai magri mang shingnip ni hpe htum ai shara kaw sha shinggrup da ai stack langai mi gaw, lapran kaw sha nga ai. Tesla gaw shanhte hpe shawng na Model 3/Y packs ni hta lang nna, hpang de laminated de galai kau ai. Dai pack gaw chassis hte shinggrup ra ai shara ni hta naw nga ai.

Rigid bar

Simple 10×50 mm (sh) 10×100 mm mill galaw ai magri mang n-gang ni, n-gun law malawng gaw n-gun-}}} ni a n-gun law malawng, LFP a hpaga lam-kvehicle packs law law nga ai. Katsi katsang hte jak hpe loi ai hku galaw lu ai, raitim, shanhte gaw hkying hkum loi mi na ai hpang, bolt hka htung ni hpe shinggrup da ma ai.

Tengman ai- mungkan a n-gun hpe ngai lang ai

Battery pack (shingra tara katsi ai lam, semi-enclosed) hta bang da ai:2.0–2.2 A/mm2 matut manoihkum tsup ai hku shim lum nga ai.
5 × 30 mm bar=150 mm2 → 300–330 Matut manoi nga ai matut manoi, 600–700 A a matu 10–30 s a matu gap hkat ai lam gaw arawn alai rai nga ai.
1.6 A/mm2 hpe quote galaw ai masha ni gaw switchgear table ni hpe copy galaw nga ai; pack kata kaw nbung lwi ai lam gaw teng sha grau kaja ai.

Ngai shani shagu mu lu ai connection ladat ni

• Laser welding: hkawhkam. Copper- to de sa na matu- hpe n-gun n-gun a n-gun-}umuminum (nickel galai shai ai lam hte) gaw n-gup magap langai hta 0.03 mΩ jaw ai.
• Bolted: n-gun- n-gun jaw ai ni gaw M10/M12 tin- hpe tsawra ai bolts + Belleville hka shin jak ni, 20–25 Nm. Loi ai magam bungli.
• Friction stir (sh) magnetic pulse welding: CATL hte kaga nkau mi hpe madung n re.

Pack ni kaw na nambat ni gaw ngai hku nna htum mat sai

• 2021–2023 Model 3/Y (Panason 2170): 4-layer × 1 × 38 mm laminate galaw da ai ≈ 500 A matut manoi
• 2024 Model Y (LG 4680): 5-layer × 1.2 × 42 mm
• Xiaomi SU{{0} V pack: 6-layer × 1 × 48 mm
• 10 mm × 80 mm rigid bar, ~350 A .
• Megapack 2 XL: 12 mm × 120 mm{3}}} a rigid bar ni, 1000 matut manoi daw langai hta matut manoi nga ai
•  

Temperature gaw yawng hkungga ai .

Copper ntsa kaw 90℃matut manoi nga ai, 110–120℃short{3} aten hpe hkap la mai ai, 130℃hta insulation film gaw myit tsang hpang wa ai. Pack law malawng gaw NTC ni hpe busbar ntsa kaw direct stick galaw nna BMS gaw hawk zawn yu nga ai.

Anhte teng sha hkrum ra ai Standard ni

ISO 6469-3 – wan shimlam

ISO 12405 – pack test spec

IEC 62660-3 – cell hte pack bungli galaw ai lam/shim lum lam

QC/T 1075 – Miwa EV pack spec (Miwa kaw dut ai rai yang)

UL 1973 (sh) UL 2580 gaw gat lawk hta hkan nna

Dai gaw grai law hkra rai nga ai. Kaga details hte ngai gaw datasheet ni hpe bai galaw ai sha rai na re.
