Hauv kev lag luam tsheb tshiab uas muaj zog tshiab, kev ntsuas qhov tseeb ntawm DC charging pawg tau dhau los ua qhov tseem ceeb rau kev lag luam.
Raws li kev lag luam tshwj xeeb thiab tsim tshiab hauv kev ntsuas hluav taws xob hauv Suav teb, Zhejiang Reallin Electron Co., Ltd. (tom qab no hu ua "Reallin") tau tsim DJZ1226G kev sib xyaw DC ntse ntsuas hluav taws xob hauv xyoo 2020 nrog kev pab los ntawm Lub Xeev Grid Zhejiang charging pawg phiaj xwm.
Cov khoom no tsis yog tsuas yog rhuav tshem cov shackles ntawm tsoos cais- hom hluav taws xob ntsuas, tab sis kuj tsim UBS 'pioneering txoj hauj lwm nyob rau hauv integrated DC meters nrog nws cov kev tsim qauv thiab ntse ua haujlwm.
1. Kev tshawb fawb thiab kev loj hlob keeb kwm
Ua ntej xyoo 2020, DC charging pawg feem ntau siv cais- hom hluav taws xob ntsuas (sab nraud shunts lossis Hall sensors), uas muaj peb qhov tsis zoo:
1. Qhov tseeb Attenuation: Cov kab hluav taws xob ntsuas hluav taws xob ntev heev tam sim no raug cuam tshuam los ntawm electromagnetic cuam tshuam, ua rau muaj kev ua yuam kev ntau dhau sijhawm ntev - siv;
2. Kev teeb tsa tsis yooj yim: Yuav tsum muaj lub shunt txuas ntxiv, ua rau cov nqi ua haujlwm siab thiab muaj kev pheej hmoo siab ntawm kev ua yuam kev;
3. Kev ruaj ntseg tsis muaj zog: Lub shunt connector tsis muaj cov hlau lead, ua rau muaj kev pheej hmoo ntawm kev cuam tshuam.
Tom qab hauv - kev tshawb fawb tob, pab pawg Reallin R&D tau tshaj tawm txoj haujlwm hauv xyoo 2020, txhawm rau tsim kom muaj kev sib xyaw DC lub zog ntsuas nrog "qhov tseeb dua, me me, thiab muaj zog tiv thaiv- muaj peev xwm cuam tshuam," codenamed DJZ1226.
2. Kev Tshawb Fawb Txog Kev Tshawb Fawb
Lub hauv paus innovation ntawm DJZ1226 nyob rau hauv nws "kev sib xyaw shunt thiab lub hauv paus ntsuas":
- Precision Leap: Ua-hauv manganese- tooj liab shunt ua tiav qhov tseeb ntawm 0.5 chav kawm (tus qauv hauv tebchaws CL0.5), deb tshaj qhov kev lag luam tus qauv tsawg dua 1.0 chav kawm;
- Anti- cuam tshuam kev hloov kho tshiab: Cov teeb liab tam sim no txuas ncaj qha mus rau lub ntsuas ntsuas nti, ua kom luv luv qhov ntsuas qhov deb mus rau qib millimeter thiab tsis txhob cuam tshuam electromagnetic;
- Power Consumption Optimization: Txo shunt kuj txo cov cua sov tsim los ntawm 90%, ua rau nws haum rau huab cua puag ncig ntawm -40℃mus rau 70 degree.
Functional Expansion Breakthroughs:
- Txhawb ntau txoj kev sib txuas lus (DL/T 645-2007, DL/T 698.45, Modbus RTU) nrog ceev mus txog 115.2kbps;
- Kev sib koom ua ke cov ntaub ntawv khaws cia muaj nuj nqi, muaj peev xwm sau tau 100 lub sijhawm them nyiaj thiab qhov tsis raug xws li overvoltage thiab overcurrent;
- Ntxiv hluav taws xob pulse tso zis interface, txhawb nqa virtual load pov thawj thiab ua kom yooj yim rau cov txheej txheem calibration.
- Dual RS485 xaiv tau: ib lub channel upload cov ntaub ntawv mus rau lub charger pawg motherboard (TCU), thiab lwm lub channel tuaj yeem xa cov ntaub ntawv mus rau lub platform saib xyuas.
3. Kev Tswj Xyuas Zoo
Txhawm rau kom ntseeg tau qhov kev ntseeg siab ntawm DJZ1226, Reallin tau tsim peb lub-tiered kev tswj hwm zoo:
R&D Kev Tshawb Fawb:
Ntau qhov kev ntsuam xyuas nruj tau ua tiav hauv CNAS-cov ntawv pov thawj (xws li EMC, ib puag ncig, thiab cov chaw kuaj xyuas qhov tseeb); ib 3m ib nrab-vave anechoic chamber tau siv los simulate siab- hluav taws xob scenarios thiab txheeb xyuas qhov muaj peev xwm tiv thaiv- cuam tshuam.
Supply Chain Collaboration:
- Ib qho plaub-kab ruam kev tswj hwm yog siv rau cov neeg xa khoom: kev tshuaj xyuas kev tsim nyog, ntawv pov thawj cov ntaub ntawv, kev tshuaj xyuas cov khoom siv, thiab kaw- kev txhim kho lub voj voog;
- Customized ntau lawm ntawm cov khoom tseem ceeb (xws li manganese- tooj liab shunts).
Smart manufacturing:
- Lub SMT (Surface Mount Technology) sib dhos, calibration, thiab cov txheej txheem soj ntsuam zaum kawg yog automated, ua tiav qib siab ntawm automation;
- MES (Manufacturing Execution System) muab tag nrho traceability ntawm cov ntaub ntawv ntau lawm, tshem tawm tib neeg yuam kev.
4. Kev ua lag luam validation
Tom qab kev tsim khoom loj hauv xyoo 2022, DJZ1226 tau txais kev lees paub kev lag luam sai sai:
- Loj - qhov chaw them nqi: Tau tshaj nrog cov neeg ua haujlwm xws li TELD, Star Charge, thiab Xiaoju Charging;
- Supercharging pawg: J50159-FD qauv txhawb 1000A siab tam sim no, sib piv cov kev xav tau ntawm megawatt supercharging;
- Photovoltaic-storage systems: Applied to DC-sab metering of photovoltaic systems, realizing integrated management of "generation-storage-siv".
5. Kev txawj ntse txawj ntse
Hauv xyoo 2024, Reallin tau hloov mus rau qhov kev tshaj lij, txawj ntse, thiab ntsuab tsim:
- Qhia cov neeg hlau ua lag luam kom ua tiav cov khoom sib dhos, vuam, thiab kev tshuaj xyuas zoo, txhim kho cov khoom zoo thaum txo nqi zog;
- Tom qab ua tiav cov peev txheej tsim tawm, lub hauv paus tshiab yuav muaj peev xwm tsim tau txhua xyoo ntau tshaj 20 lab ib zaug / peb-theem hluav taws xob meters;
- Kev sib txuas ntawm microgrid thev naus laus zis, "zero-carbon ntau lawm kab" tau raug tsim, txhawb nqa lub hom phiaj ntawm lub ntiaj teb carbon neutrality.
