Xov Xwm - Kev Sib Piv ntawm Relay vs MOS BMS: Cov Ntawv Qhia Txog Kev Siv Tam Sim No Siab

Thaum xaivLub Tshuab Tswj Xyuas Roj Teeb (BMS) rau cov ntawv thov tam sim no siabIb yam li cov tsheb thauj khoom hluav taws xob thiab cov tsheb ncig xyuas, ib qho kev ntseeg dav dav yog tias cov relays yog qhov tseem ceeb rau cov hluav taws xob siab dua 200A vim lawv qhov kev kam rau siab tam sim no thiab kev tiv thaiv voltage. Txawm li cas los xij, kev nce qib hauv MOS thev naus laus zis tab tom sib tw rau lub tswv yim no.

Hais txog kev siv, cov qauv BMS niaj hnub no txhawb nqa cov hluav taws xob los ntawm 200A txog 800A, ua rau lawv haum rau ntau yam xwm txheej siab. Cov no suav nrog cov maus taus hluav taws xob, cov tsheb golf, cov tsheb thauj khoom txhua qhov chaw, thiab txawm tias cov ntawv thov hauv hiav txwv, qhov twg cov voj voog pib-nres ntau zaus thiab kev hloov pauv dynamic load xav tau kev tswj hwm tam sim no. Ib yam li ntawd, hauv cov tshuab logistics xws li forklifts thiab cov chaw them nyiaj mobile, MOS cov kev daws teeb meem muab kev koom ua ke siab thiab lub sijhawm teb sai.

Thaum ua haujlwm, cov txheej txheem relay-based muaj kev sib dhos ua ke nrog cov khoom ntxiv xws li cov transformers tam sim no thiab cov chaw muab hluav taws xob sab nraud, xav tau kev txuas hluav taws xob thiab kev sib txuas. Qhov no ua rau muaj kev pheej hmoo ntawm cov teeb meem virtual soldering, ua rau muaj kev ua tsis tiav xws li hluav taws xob tsis ua haujlwm lossis kub dhau sijhawm. Qhov sib piv, MOS cov phiaj xwm muaj cov qauv tsim ua ke uas ua rau kev teeb tsa thiab kev saib xyuas yooj yim. Piv txwv li, kev kaw relay xav tau kev tswj hwm nruj kom tsis txhob muaj kev puas tsuaj rau cov khoom, thaum MOS tso cai rau kev txiav ncaj qha nrog qhov yuam kev tsawg kawg nkaus. Cov nqi saib xyuas rau MOS yog qis dua 68-75% txhua xyoo vim muaj tsawg dua qhov chaw thiab kho sai dua.

Kev tshuaj xyuas tus nqi qhia tau hais tias thaum cov relays zoo li pheej yig dua thaum xub thawj, tag nrho cov nqi ntawm MOS lub neej luv dua. Cov kab ke relay xav tau cov khoom ntxiv (piv txwv li, cov pas nrig cua sov), cov nqi zog ua haujlwm siab dua rau kev debugging, thiab siv ≥5W ntawm lub zog tas mus li, thaum MOS siv ≤1W. Cov neeg sib cuag relay kuj hnav sai dua, xav tau 3-4 npaug ntxiv kev saib xyuas txhua xyoo.

Hais txog kev ua tau zoo, cov relays muaj kev teb qeeb dua (10-20ms) thiab tuaj yeem ua rau lub zog "stuttering" thaum lub sijhawm hloov pauv sai xws li kev tsa forklift lossis nres tam sim ntawd, ua rau muaj kev pheej hmoo xws li kev hloov pauv voltage lossis qhov yuam kev sensor. Qhov sib piv, MOS teb hauv 1-3ms, muab kev xa hluav taws xob du thiab lub neej ntev dua yam tsis muaj kev sib chwv.

Hauv kev xaus, cov txheej txheem relay tej zaum yuav haum rau cov xwm txheej yooj yim uas muaj tam sim no qis (<200A), tab sis rau cov ntawv thov tam sim no siab, MOS-raws li BMS cov kev daws teeb meem muaj qhov zoo hauv kev yooj yim siv, kev siv nyiaj tsim nyog, thiab kev ruaj khov. Kev lag luam vam khom rau relays feem ntau yog raws li cov kev paub dhau los; nrog rau MOS thev naus laus zis loj hlob, nws yog lub sijhawm los soj ntsuam raws li qhov xav tau tiag tiag es tsis yog kev lig kev cai.
