Yuav ua li cas siv diodes nyob rau hauv kev tiv thaiv thiab kev tiv thaiv cov roj teeb lithium roj?

, Qhov sib raug zoo ntawm Diode tshuab cov yam ntxwv thiab Lithium roj teeb kev tiv thaiv
1. Unidirectional conductivity: Lub Tsev Tiv Thaiv Yooj Yim
Cov yam ntxwv tseem ceeb ntawm kev dag nyob rau hauv unidirectional conduction ntawm nws pn kev sib deev, uas tsuas yog tso cai ntws los ntawm anode (k) rau cricehode (k), nrog kev txiav tawm rov qab. Cov yam ntxwv no cov ntaub ntawv muaj kev tiv thaiv triple hauv cov roj teeb lithium roj teeb:

Anti rov qab Kev Tiv Thaiv Kev Sib Txuas Chaws: Schottky Diodes (xws li MBR1045CT) tau txuas nrog hauv kev them hluav taws xob lossis kev tsim circuit co. Thaum lub zog polarity tau thim rov qab, tus diode txiav tawm los tiv thaiv cov thaub qab roj teeb tam sim no (BMS). Raws li cov ntaub ntawv xeem los ntawm cov chaw tsim khoom hluav taws xob tshiab, tus lej BMS ua tsis tiav ntawm 92% tom qab tau txais kev daws teeb meem no.
Polarity rho tawm: Hauv kev sib cais cell series, lub cev cais ntawm kev them cov hluav taws xob thiab cov kev tawm dag zog hauv lub voj voog ua tiav los ntawm cov khoom siv phom. Piv txwv li, qee qhov chaw nres tsheb hluav taws xob lub chaw nres tsheb
Anti Backflow Kev Tiv Thaiv: Txuas TVS Diode (xws li SMaj5.0a) hauv kev sib tw ntawm DC / DC converter. Thaum lub voltage ntawm lub nra ua kom tiav kev txawv txav, cov teeb meem tawm sai sai, tiv thaiv cov roj teeb lithium los ntawm kev thim rov qab voltage cuam tshuam.
2. Ceev hloov cov yam ntxwv: Kev ua tau zoo nyob rau hauv high - zaus scorarios
Schottky diodes, nrog lawv cov hlau cov kev sib tw ua qauv, ua tiav ze rau lub sijhawm luv luv (TRR<10ns), demonstrating significant advantages in high-frequency switching power supplies

Nruam tam sim no tam sim no: nyob rau hauv lub buck / boost dopholure, thiab lawv cov khoom siv SS34) (VF ≈ 0.3v) txo qhov poob los ntawm ntau dua 60%. Qhov kev sim tiag tiag ntawm kev tswj hwm lub roj teeb tsav tsheb tau qhia tau tias tom qab tau txais cov phiaj xwm no, DC / DC hloov zuj zus kev nce los ntawm 88% mus rau 94%.
Synchronous Tsom Faib: Hauv cov xwm txheej tsis tshua muaj hluav taws xob (xws li 48v zog khoom siv tau los ntawm cov khoom siv asschronous), QRR) thiab txo lub zog EMI suab nrov los ntawm 15DB.
3. Avalanche tawg cov yam ntxwv: Qhov kawg tiv thaiv kev tiv thaiv kev hloov pauv hloov pauv
TVS DIODES CLAMPAN CL VASTION PICIT Voltage rau kev nyab xeeb hauv picosecond lub sij hawm dhau los ntawm avalanche tawg xws li:

Clamp Voltage (VC): Nws yuav tsum qis dua qhov ntau tshaj plaws rated voltage ntawm bms nti (piv txwv li rau STM32G4 series, VC yuav tsum<36V)
Peak Mem tes hluav taws xob (PPP): Raws li IEC 61000-4-5 tus qauv, nws yuav tsum tau withstand ib qho tam sim no ntawm tsawg kawg 1008 nyob rau hauv 8/20 μ S wavegform
Tom qab siv smbj15ca TVs dodes donovoltaic cia kom zoo ntawm 3000v tsim tawm los ntawm kev siv hluav taws xob ntau ntawm 3000 teev
2, cov ntawv thov raug cai thiab kev ua engineering
1. Tsim kev them cov kev them nyiaj rau hauv Circuitface
Ntawm cov lus tawm xaus ntawm lub zog hluav taws xob xaus ob lub tsheb (ntawm {{{0} -}}} qib kev tiv thaiv architecture:

Thawj qib kev tiv thaiv: Series Scd1045-40) yog siv los tiv thaiv kev sib txuas rov qab, thiab lawv cov 40V withstand voltage npog cov tseev kom muaj ntawm 12v / 24V tshuab
Kev tiv thaiv thib ob: parallel TVs diodes (xws li P6Ke36CA) Surpress Surger Voltage ntais ntawv cov lus qhia txog BMS
Kev tiv thaiv qib thib peb: Siv tus kheej rov qab Fuses (PptC) kom ua tiav kev tiv thaiv kev tiv thaiv dhau los, sib sau ua kev tiv thaiv dailesary
Raws li cov ntaub ntawv ntsuas tiag tiag los ntawm cov tuam txhab tsheb ua tsis tau them nyiaj los ntawm 0.8% mus rau 08% thiab txo tus nqi kho txhua xyoo los ntawm 23 lab Yuan.
2. Kev tiv thaiv tshiab hauv kev tiv thaiv ntawm lub xov tooj ntawm tes
Nyob rau hauv Tesla 4680 roj teeb module, ib lub passcing circuit co nrog schottky diodes (xws li bat54s) yog siv los ua kom tiav:

Kev ntsuas kev tswj hwm tam sim no: los ntawm kev kho cov Diode conduction voltage nco (r} {1} {1} {1} Muaj qhov ntsuas tsis pub dhau hauv 200ma
Thermal khiav RUNAWASS: Thaum lub zog hluav taws xob ntawm lub roj teeb tsis txaus ntseeg, tsim cov kev sib npaug los tiv thaiv kev dircal diffusion
Qhov kev tsim qauv no nce lub voj voog lub neej ntawm lub roj teeb pob los ntawm 35% thiab txo cov peev nyiaj tsawg kawg ntawm 0.8% ib hlis rau 0.5%.
3. EMI kev ua kom zoo ntawm wireless them
Hauv Xiaomi 80W Wireless Setging Module, qhov siab- Cov suab nrov muaj cov suab nrov los ntawm cov Diode sib xyaw ua ke:
