The MPPT (Maximum Power Point Tracking) test of photovoltaic inverters is an important test to verify whether the inverter can track and maintain the maximum output power point of the photovoltaic cell.The purpose of MPPT testing is to ensure that the inverter can adapt to changes in environmental factors such as light intensity and temperature, thereby maximizing the use of solar energy resources and improving power generation efficiency.

AFE nti yog lub hauv ntej-kawg integrated circuit siv rau analog teeb liab tau txais thiab ua. Nws tuaj yeem nthuav dav, lim, qauv, ntsuas thiab ua cov teeb liab tawm tswv yim los pab txhawb kev tsom xam ntawm qhov kawg ntawm MCU (processor). Tam sim no, AFE chips tau siv dav hauv ntau lub lag luam xws li tsheb fais fab, lub zog cia, 3C electronics, thiab lwm yam. Siv lub tsheb fais fab thiab lub zog cia ua piv txwv, AFE chips yog cov khoom tseem ceeb ntawm tsheb BMS thiab lub zog cia BMS. Kev loj hlob sai ntawm cov tsheb hluav taws xob, lub zog cia thiab lwm yam kev lag luam tau ua rau muaj kev loj hlob ntawm kev thov hauv AFE chip lag luam. Nws qhov kev ua tau zoo ncaj qha txiav txim siab qhov raug thiab kev ntseeg tau ntawm BMS kev ua haujlwm. Yog li ntawd, AFE chip testing kuj tau dhau los ua qhov tseem ceeb ntawm cov tuam txhab nti, uas tso siab rau cov kev xav tau ntawm kev ua haujlwm, kev teeb tsa channel chaw nres tsheb, sim synchronization thiab qhov tseeb ntawm cov khoom siv ntsuas.

Lub automotive hluav taws xob lub thawv yog ib qho hluav taws xob hub rau kev muab tsheb fais fab kev faib tawm thiab kev tiv thaiv Circuit Court. Nws tuaj yeem ua kom yooj yim rau kev sib txuas cov hlua khi ntawm tag nrho lub tsheb. Nws cov khoom feem ntau suav nrog MCU, relay fuse Circuit Court, tswj logic Circuit Court, kev sib txuas lus Circuit Court, thiab lwm yam. Txhawm rau kom muaj kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm ntawm lub tsheb, peb yuav tsum ua ntau yam kev ntsuam xyuas ntawm lub ntse hluav taws xob lub thawv, nrog rau kev tswj xyuas thiab tsav tsheb. , kev sib txuas lus transceiver, thiab lwm yam, los simulate ntau yam kev ua haujlwm huab cua xws li overload, overtime, nquag hloov pauv ntawm lub tsheb ntse hluav taws xob lub thawv hauv ntau qhov chaw huab cua los ntsuas nws txoj kev ntseeg tau thiab ruaj khov.

Txoj kev loj hlob sai ntawm lub zog tshiab tsheb kev lag luam kuj tau tsav txoj kev loj hlob ntawm lub tsheb nyob rau hauv cov kev taw qhia ntawm electrification thiab txawj ntse, uas tau ua rau ib tug nruam nce nyob rau hauv qhov kev thov rau wiring harnesses rau ib lub tsheb. Raws li cov ntaub ntawv txheeb cais, qhov nruab nrab ntawm kev siv cov hlua hluav taws xob rau ib lub tsheb yuav nce los ntawm 1.5 kilometers hauv 2000 mus rau 4.5 kilometers nyob rau hauv 2025. Qhov kev nce ntawm kev siv cov xov hlau automotive harnesses tau muab tso rau ntau dua cov kev xav tau rau kev ntseeg siab thiab kav ntev ntawm cov khoom sib txuas. Ntawm qhov tod tes, kev laus ntawm cov hlua khi thiab lwm yam xws li pob thaum tsav tsheb yuav ua rau cov kev sib txuas ntawm cov terminals kom xoob, ua rau lub zog tsis ua haujlwm tam sim lossis luv luv, uas yuav cuam tshuam rau kev nyab xeeb ntawm tag nrho lub tsheb mus rau qee yam. Ntawm qhov tod tes, kev nce siab ntawm lub zog hluav taws xob tsheb ceev ceev thev naus laus zis thiab lwm lub tshuab hluav taws xob hauv lub nkoj kuj tseem cuam tshuam rau lub neej kev pab cuam ntawm high-voltage wiring harnesses. Yog li ntawd, nws yog ib qho tsim nyog los ntsuas qhov kev ua tau zoo ntawm cov hlua khi thiab lub davhlau ya nyob twg rau cov kev ntsuas kev ua tau zoo xws li kev cuam tshuam tam sim, kev laus, thiab kev luv luv.

Sab hauv hluav taws xob hluav taws xob ntawm lub tsheb hluav taws xob yog ib txoj haujlwm ua haujlwm, uas cov khoom tseem ceeb yuav tsum tau hloov kho tshwj xeeb rau cov tsheb hluav taws xob. Siv lub DC-DC converter ntawm lub tsheb fais fab ua piv txwv. Nws yog ib qho kev txuas ntxiv ntawm cov khoom siv hluav taws xob hloov hluav taws xob thiab tau tsim los rau hauv DC-DC converter rau hluav taws xob tsheb. Qhov sib txawv ntawm lawv yog qhov input voltage, tam sim no thiab lub zog ntawm DC-DC converter rau cov tsheb fais fab loj dua.

At present, BDU is mostly customized according to the needs of the car manufacturer itself, so it is important to collect information related to customer needs and the electrical performance of the customer's vehicle.
