Akin et Kaukolan na BESS Mo so UL Certification—tan Antoy Nagawa No Ag-itan

Magmaliw kamin matua-aliwan saya so sanka-exciting ya topic nipaakar ed panagtipon na enerhiya. Anggapoy ombangon ya manisip, "Agko la alagaren so mansukimat ed saray sertipikasyon na kaligenan na baterya natan."

Say UL 1973 et onloob ed UL 9540. Say UL 9540A ya testing et onloob ed UL 9540. Agmo nayarin i-shortcut so chain, tan agmo labay.

UL 1973: Kasin Maong so Baterya Mo No Walay Stress?

UL 1973 (Saray Baterya ya Uusaren ed Saray Ag-onkukurang, Auxiliary Power tan Light Electric Rail Applications) et wala la manlapu nen 2013 tan linmabas ed angkabaleg iran pananguman nen2018 tan lamet ed 2022. Kada rebisyon et pinalaknab to ray kakaukolanen parad lithium-ion chemistries tan pinalaknab toy sakop pian ilaktip so nickel-metal hydride tan VRLA systems.

Sayan estandarte et nipaakar ed baterya ya manbukbukor-sarag to kasin naasikaso so panag-abuso ya ag-onkapuy odino onsabog?

No Antoy Peteg ya Itsura na Panubok

Inapag mi iya ed limaran balde, tan diad tua, saray fire test so makaalay imano na amin:

Panag-abuso ed kuryente.Say laboratoryo et man-overcharge na baterya, man-overdischarge, man-short, man-feed na imbalanced current, tan man-hammer ed high-rate charging. Say kriterya na pakapasa? Anggapo ed saraya so nepeg ya mamawala na pool, isabog, mapeligron gas, pakakuryente, odino pansengegan na pakaderal na proteksion iran sirkito. Singa mapatnag, balet wala ray anengneng min battery pack ya nanlapud saray supplier ya anggapoy ngaran da ya ag makaliktar ed overcharge test ya anggapoy bentilasyon.

Saya so bengatla ya mamapagalaw ed saray ag-inkayadyari na solder joints tan mangipapatnag na marginal cell-to-busbar connections. No akaawat ka la na sakey a paleta na saray baterya ya walay abel iran suyok to, natalosan mo no akin ya importante iya.

Mairap iran kaliberliber.Thermal cycling ed baetan na arawrawin temperatura, humidity chambers, salt fog exposure, dust ingress. No say BESS mo et onla ed tapew na atep ed Phoenix odino diad gilig na dayat ed Florida, sarayan test so mangibaga ed sika no kasin mansiansia itan. Parad sikatayosistema na kabinet ed paway, sarayan subok ed kaliberliber et mairap lapud saray yunit et akaarap ed panaon ed interon taon.

Say pakapatnagan na apoy-say tepet na amin.Walay duaran subok dia. Say external fire test et mangiyan na kompleton karga ya baterya ed tapew na heptane pool fire ed loob na 20 minutos, insan to itan tupaken na fire hose- ya singa say aktual ya ebat na fire department. Say internal fire test et ginagalan mamapawala na thermal runaway ed sakey a selda ya walad sentro pian nanengneng no kasin onkukurang so inkagba. Say sistema et kaukolan ya mangipatnag ya anggapoy peligro na panagsabog ed anggan dinan a senaryo. Sarag mon basaen so interon paraan na panagsukimat edsayan pakanengnengan ed UL 1973 fire testing.

Say UL 1973 et mankaukolan na sistematikon panagsukimat ed inkagba-kaslakan et FMEA-parad parehon BMS hardware (ya inebalwar kadaUL 991) tan software (ya inebalwar kadaUL 1998). Say manunan konsepto dia etsakey a -fault tolerance: anggano onsaew so sakey a proteksion, nepeg ya mansiansian ligtas so sistema. Anggapoy anggan sakey a punto na inkagba ya nepeg ya pansengegan na pool odino insabog.

Maapit met itan ya mikonektaan edIEC 62619, say internasyonal ya katumbas to, kanian say sagpot ed panag-testing et mansiansia no man-deploy ka ed parehon merkado na North America tan global.

UL 9540: Kasin Mankakasakey so Intiron Sistema?

Diad saya et magmaliw ya tua. Say UL 1973 et mansusubok ed baterya diad laboratoryo. Say UL 9540 et mansusubok edinteron sistema-baterya, inverter, BMS, thermal management, enclosure, wiring, kontrol, amin.

Say evaluation et mansaklaw na apatiran domain, tan labay min pantongtongan no antoy talagan makapabigla ed totoo ed praktis:

Kaligenan ed kuryenteet kaslakan ya diretsaan no saray component-level certs mo et wala lad pasen da. Limitasyon na fault current, dielectric standstand, ground-fault detection, BMS shutdown logic ed silong na abnormal iran kondisyon. Say inverter et kaukolan toy sarili toUL 1741listing, tan saray baterya et mankaukolan na UL 1973. Walay sakey a kustomer mi nen imbeneg a taon ya angala na saray baterya ed sakey a vendor tan saray inverter ed sananey-parehon indibidual ya sertipikado-insan to labat adiskobre ya say espisipikon kombinasyon et ag ni nasubok bilang sakey ya integrated system. Apatiran bulan so inlabas da ed satan.

Say kaligenan ed makina tan istrukturadiman so inloob na komaduan edisyon na UL 9540 (epektibo nen Hulyo 2022) na sakey a kakaukolanen ya amabigla ed pigaran managgaway produkto:say ESS enclosure et nepeg ya metal. No manggagawa kay containerized BESS, say 20-foot o 40-foot ya container et kualipikado. Balet wala ray melag ya sisteman singa kabinet ya manguusar na composite ya padir ya kaukolan ya umanen so desinyo da.

UL 9540A: Antoy Nagagawa No Walay Nagawa?

Saya so estandarte ya maslak ya ag natatalosan na totoo, kanian linisan tayo nin unona so sankabalgan ya lingon pakatalos:Say UL 9540A et sakey a paraan na panagsukimat, aliwan sakey a sertipikasyon.Anggapoy ontan ya "UL 9540A certified."

Importante itan ya pandumaan ta say UL 9540A et anggapoy binary pass/fail to. Mangipapawala itandatos na performance-espisipiko, data nipaakar ed no antoy nagagawa no say sakey a selula et onloob ed thermal runaway tan no kasin satan ya ag-inkayadyari et onla ed kabangibang iran selula, module, odino interon sistema. Sayan data so repasoen na saray fire department tan AHJ pian nadesisyonan no kasin say pangipaalagey yo et ligtas ya naaprobaan.

Say Four-Level ya Pantutumbokan na Subok

Say UL 9540A et manguusar na progresibon paraan. Say panagsukimat et onggapo ed melag tan ondarakel tan diad kada lebel, say resulta so mandetermina no kasin kaukolan ni so kaaruman a panagsukimat.

Level 1 - Cell

Say sakey a selula et napepetang anggad onloob ed thermal runaway. Say laboratoryo et mansukat na kabuoan ya ipaway ya enerhiya, say komposisyon na gas, tan say karakel na gas. Saya so mangipapanengneng na sankagrabian ya inkagba na sakey a selula-say baseline ya "panon karakel so nagawa ed sakey a selula?"

Level 2 - Module

Say manunan prinsipyo: no say resulta na sakey a lebel et makaabot ed saray kriterya na performance, nayarin ag mo la kaukolan so onla ed ontumbok a lebel. Balet no walay naimano ya gas ya napoolan ya onlampas ed limitasyon na limitasyon, kaukolan so kaaruman ya panagsukimat ed kadena.Angipalapag so Mayfield Renewables na malet ya teknikal ya walkthroughno panon ya mikonektaan irayan lebel ed saray kakaukolanen na kodigo na NFPA 855.

No Antoy Gastos ed Panlaktip ed UL

Abuloyan so limbo.Sakey ya integrator ed Texas so angala na aliwan -UL- ya akalista ya containerized BESS pian makatipid na ngalngalin $40,000 ed panagsaliw. Impulisay na lokal ya AHJ so permit. Say field evaluation-tan on-site safety assessment na NRTL- et posibli, balet mas baleg so nagastos to nen say orihinal ya tinipon, 14 a simba, tan sakey labat ya espisipikon instalasyon so sakopen to. Say ontumbok a proyekto et kaukolan ya igapo lamet so proseso manlapud gapo.

Say seguro et andiay dalan.Saray commercial property insurers et naynay ya mankaukolan na UL 9540 listing tan UL 9540A test data bilang preconditions parad coverage ed saray pasilidad ya walay BESS. No anggapo iratan, ag ka makaseguro odino manbayar ka na saray premium ya maneral ed pinansyal ya modelo na proyekto. Anengneng mi so 500 kWh ya proyekto na C&I ed California ya naatrasado na anem bulan lapud ag-iganggan na insurance underwriter so coverage anggad ag ni nagawa na supplier so 9540A report.

Diskwalipikasyon na insentibo.Say Federal Investment Tax Credit (ITC), say Self-Generation Incentive Program (SGIP) na California, tan sayPrograma na Energy Storage Solutionsamin et mankaukolan na UL-listed ya kagawaan. Say New Technology Application form na Connecticut et malinew ya onkekerew na UL 9540 listing number. Anggapoy listaan, anggapoy insentibo, anggapoy kaso ed ekonomya.

Liability exposure.Simpli labat iya: no walay nagawa ya aliwa ed sakey ya sistema ya aliwan -sertipikado, say legal ya responsabilidad et walad siopaman ya nandesisyon ya mangi-install ed satan. Saya so peligro ya ag labay na karaklan ya akankayarian na pasilidad tan developers ya awaten- tan ag da nepeg ya gawaen.
