Hauv thaj tsam ntawm kev tswj hwm roj teeb (BMS), ib qho kev pheej hmoo tshaj plaws rau cov kua qaub thiab Ni-Cd roj teeb yog ripple tam sim no thiab ripple voltage. Txawm hais tias feem ntau pom tsis pom, cov kev cuam tshuam hluav taws xob no ua zoo li cov neeg tua neeg uas ntsiag to, txo cov roj teeb lub neej thiab ua rau muaj kev ntseeg siab ntawm cov tshuab hluav taws xob tseem ceeb hauv cov chaw zov me nyuam, cov chaw ua haujlwm, thiab cov chaw sib tham.

 

Dab tsi yog Ripple Current thiab Ripple Voltage?

Lub roj teeb zoo tagnrho rau kev them nqi thiab kev tso tawm yuav tsum yog lub zog DC du. Txawm li cas los xij, vim muaj kev hloov pauv ntau zaus hauv cov chargers thiab UPS cov tshuab, cov khoom siv AC tsis xav tau tshwm sim:

 

Ripple Tam sim no - AC tivthaiv superimposed ntawm DC tam sim no, fluctuating nrog load thiab them / tawm mus.

 

Ripple Voltage  - AC fluctuation superimposed ntawm DC voltage, ntsuas nyob rau hauv ncov-rau-peak lossis RMS qhov tseem ceeb.

 

Cov ripples no feem ntau tshwm sim hauv 50Hz - 1kHz ntau thiab, txawm tias tsis pom, muaj nyob hauv txhua lub voj voog them.

 

 

Vim li cas Ripple hem Roj Teeb Kev Noj Qab Haus Huv?

Rau txhua lub roj teeb saib xyuas qhov system, tsis quav ntsej ripple yog qhov txaus ntshai. Thaum lub sij hawm, ripple ua rau irreversible puas tsuaj:

 

Accelerated Phaj Corrosion  - Ripple tam sim no ua rau cov khoom siv ua haujlwm, txo cov kev pab cuam lub neej.

 

Thaum tshav kub kub heev  - Ripple ua rau muaj kev tiv thaiv thiab kub tsim; Txhua txhua 10 ° C nce ob npaug ntawm cov tshuaj tiv thaiv, ua kom cov electrolyte evaporation sai.

 

Peev Xwm Poob  - Lub sij hawm ntev ripple raug txo kom muaj peev xwm ua tau zoo los ntawm 30-50%, txo qis roj teeb kev saib xyuas kev noj qab haus huv thiab kev cia siab rau lub cev.

 

Vim li cas Standard Battery BMS Systems tsis txaus?

Feem ntau cov roj teeb BMS tsuas yog ntsuas qhov ntsuas tsis zoo li qhov hluav taws xob thiab tam sim no, tsis quav ntsej cov teebmeem ripple. Qhov no zoo li kuaj xyuas lub cev kub tab sis tsis quav ntsej txog cov ntshav siab hloov pauv - cov cim qhia kev noj qab haus huv tseem ceeb tau ploj lawm.

 

Yog vim li cas cov roj teeb saib xyuas siab heev yuav tsum suav nrog kev saib xyuas ripple kom ntseeg tau tiag tiag.

 

DFUN PBMS9000: Advanced Ripple Saib Xyuas rau Lub Zog Tseem Ceeb

Raws li lub ntiaj teb cov chaw muab kev tswj hwm roj teeb, DFUN muab PBMS9000 Series, tsim tshwj xeeb rau cov chaw loj cov ntaub ntawv, cov chaw nres tsheb, thiab cov txheej txheem tseem ceeb. Nws mus dhau kev saib xyuas ib txwm muaj nrog kev tshawb pom ripple siab:

 

1. Kev ntsuas siab

 

Ripple tam sim no: 0 ~ 400A ncov, 50Hz - 1kHz, daws teeb meem 0.01A

 

Ripple Voltage: 2 ~ 100VDC ncov, daws teeb meem 0.01V

 

Integrated saib xyuas ntawm voltage, tsis kam, SOC, SOH, thiab kub

 

2. 24/7 Roj Teeb Saib Xyuas Kev Noj Qab Haus Huv

 

Kev soj ntsuam online ntawm lub sijhawm tiag tiag nrog 5-xyoo cov ntaub ntawv khaws cia

 

Multi-level tswb ntawm SMS, email, thiab mobile app, teb <10s

 

3. Scalable & Robust BMS System

 

Txhawb nqa txog li 6 cov hlua roj teeb (420 - 480 hlwb) rau VRLA thiab Ni-Cd roj teeb

 

Anti-interference tsim kom ntseeg tau tias kev ua haujlwm hauv UPS ib puag ncig

 

Txhawb Modbus, SNMP, MQTT, thiab IEC61850 raws tu qauv rau seamless kev koom ua ke

 

4. Txhim khu kev qha, muaj ntawv pov thawj tshuaj

 

Ua raws li CE, FCC, RoHS, UL ntawv pov thawj

 

Dual fais fab tsim kom ntseeg tau tias kev saib xyuas tsis txhob kaw

 

 

Pov thawj tus nqi hauv qhov project tiag

Nyob rau hauv cov haujlwm saum toj kawg nkaus nrog Google cov chaw zov me nyuam thiab lwm lub ntiaj teb sab saum toj tsib lub tuam txhab cov ntaub ntawv chaw, PBMS9000 series tau ua pov thawj nws tus nqi.

 

Nyob rau hauv ib qho chaw thoob ntiaj teb cov ntaub ntawv, PBMS9000 kuaj pom ripple abnormalities 6 lub hlis ua ntej, tiv thaiv UPS loj.

 

Roj teeb lifespan txuas ntxiv los ntawm 40%, txo cov nqi hloov pauv.

 

Xaus

Cov roj teeb yog cov kab kawg ntawm kev tiv thaiv hauv ib qho kev tswj hwm roj teeb, thiab ripple yog qhov zais tab sis muaj kev hem thawj loj. DFUN PBMS9000 Series muab cov roj teeb uas muaj peev xwm soj ntsuam cov kab ke txuas ntxiv mus, xa cov kev tshawb pom ntawm lub sijhawm tiag tiag thiab kev saib xyuas kev noj qab haus huv ntawm roj teeb.

 

DFUN PBMS9000 - qhov ntse dua, muaj kev nyab xeeb, thiab txhim khu kev qha BMS kev daws teeb meem rau cov roj ntsha lead-acid thiab Ni-Cd hauv lub luag haujlwm tseem ceeb ntawm lub zog hluav taws xob.

 

Hu rau DFUN hnub no kom paub seb peb cov roj teeb siab BMS cov kev daws teeb meem tuaj yeem tiv thaiv koj lub zog hluav taws xob li cas.
