Msampha wa Monolithic: Chifukwa Chake Batri Imodzi Yaikulu Imavulaza Ogwira Ntchito

Wogwira ntchito yokonza zinthu ankafunika mphamvu yochaja ya 300 kW ndipo, potsatira uphungu wa katswiri, anagula njira imodzi yosungiramo zinthu yolumikizidwa ya 480 kWh kuti ikwaniritse "kukula kwa mtsogolo." Patatha miyezi khumi ndi isanu ndi itatu, kugwiritsa ntchito kunafika pa 40% yokha ya mphamvu ya batri: batriyo inali itakula pang'onopang'ono kuposa momwe zinalili kale, chiwongola dzanja cha malowo chinali 220 kW, ndipo batriyo inali yaikulu kwambiri inali kuyenda pang'onopang'ono - njira yogwiritsira ntchito yosungiramo zinthu yomwe inali yopindulitsa kwambiri. Choyipa kwambiri n'chakuti, pamene inverter yokha inalephera, malo onse ochaja anali amdima kwa masiku asanu pamene chosinthira chinatumizidwa kuchokera kumayiko ena.

Njira ya monolithic imalepheretsa ogwira ntchito pa ma axes atatu: nthawi yogulira (kulipira lero mphamvu zomwe zagwiritsidwa ntchito m'zaka zitatu), kulephera kwa blast radius (malo amodzi olephera amachotsa chuma chonse), ndi kusinthasintha (kapangidwe kokhazikika sikungasunthike pamene njira za fleet kapena mapangidwe a malo asintha). Izi ndi njira zenizeni zolephera zomwe kapangidwe ka modular kamachotsa, ndichifukwa chake modular BESS yakhala kapangidwe kokhazikika mu gawo lazamalonda ndi mafakitale, ndipo chifukwa chake pafupifupi zomangamanga zonse zofalitsidwa ndi ogwira ntchito za grid ndi osonkhanitsa zimatenga zomangira zokhazikika, zokhazikika.

Kodi Kusinthasintha Kumatanthauza Chiyani mu BESS?

Kusinthasintha kwa mphamvu ya EV yolumikizidwa ndi BESS kumagwira ntchito pamlingo iwiri: njira yamagetsi ndi njira yamagetsi. Njira yamagetsi imakhala ndi mayunitsi osinthira mphamvu omwe ali ndi mbali ziwiri - a MIDA, ma module omwe ali mu [20–40 kW class](https://www.midapower.com/ev-charging-power-module) omwe amasintha AC grid kukhala DC ya batri ndi chojambulira, ndi mitundu yozizira yamadzimadzi mpaka 125 kW yamagetsi amphamvu kwambiri. Njira yamagetsi imakhala ndi mabatani wamba, nthawi zambiri 20–100 kWh iliyonse, yomangidwa kuchokera ku maselo ovomerezeka a LFP okhala ndi BMS yolumikizidwa komanso kayendetsedwe ka kutentha.

Bloko lililonse limadzilamulira lokha: BMS yakeyake, kulumikizana kwake koziziritsira, ndi ma interfaces okhazikika a makina ndi magetsi. Mabuloko amaphatikizidwa motsatizana komanso motsatizana kuti afike pa voltage ndi mphamvu zomwe akufuna. Ichi ndi chomwe chimasiyanitsa modularity yeniyeni ndi gawo lokha: bloko lililonse likhoza kusinthidwa, kukonzedwa, kapena kusinthidwa popanda kukhudza ena, ndipo wowongolera makina amasinthidwanso ku chiwerengero chatsopano cha mabuloko. Wogwiritsa ntchito amakulitsa kuchokera pa 240 kWh kufika pa 482 kWh amangowonjezera bloko lina lokhazikika, kulilumikiza ku basi ya DC, ndikulola EMS kukonzanso - palibe kukonzanso, palibe kuyenerera kwa malo, palibe nthawi yayitali yopuma.

Modular vs. Monolithic: Kuyerekeza Mbali ndi Mbali

Gome loyerekeza likuwonetsa zomwe ogwira ntchito amanena m'machitidwe: machitidwe a monolithic amapambana pokhapokha ngati mbiri ya katundu wa tsambalo ili yokhazikika mokwanira kuti katunduyo akhale ndi moyo wonse - mkhalidwe wosowa pamsika wochaja pomwe kuchuluka kwa magalimoto, kuchuluka kwa mphamvu, ndi kapangidwe ka mitengo yonse zimasinthasintha mkati mwa zaka zisanu.

Kukulitsa Popanda Kumanga Mopitirira Muyeso: Kukula Koyenera ndi Ma Block Okhazikika

Kukula kolondola ndiye chisankho chachikulu kwambiri pazachuma pa ntchito yosungira, ndipo modularity imapangitsa kuti isinthe. Lamulo laukadaulo pakuchaja kwa EV ndilakuti kukula kwa malo osungira kuli pa 0.5–1× mphamvu yayikulu yochaja pamalopo mu kilowatt-hours: malo a 120 kW nthawi zambiri amafunikira 120–240 kWh; malo a 320 kW amafunikira 240–480 kWh. [Banja la zinthu zosinthika](https://www.midapower.com/energy-storage-charging-station) limalola wogwiritsa ntchito kugula malire otsika kaye ndikukulitsa pamene deta yogwiritsira ntchito ikugwirizana nayo.

Makonzedwe onse ali ndi banja limodzi la ma module, kotero woyendetsa ntchito yemwe akuyendetsa malo asanu pa masikelo osiyanasiyana amakhala ndi gawo limodzi lamagetsi lowonjezera ndi batri limodzi lowonjezera pa netiweki yonse. Kukula pakati pa makonzedwe ndi kukonzanso malo - kuwonjezera ma block ndikukonzanso EMS - osati kugula kwatsopano.

Ndondomeko Yokonza, Kubwezeretsa Zinthu, ndi Zosungirako

Kupezeka ndi komwe modularity imapezera malo ake ogwirira ntchito. Mu kapangidwe ka mphamvu ya modular, chowongolera siteshoni chimagwiritsa ntchito N+1 redundancy: dongosolo la 6×40 kW la block yamagetsi yotumikira 240 kW limalekerera kulephera kwa module iliyonse popanda kuchepetsa mphamvu ya malo, ndipo kulephera kwachiwiri kumangochepetsa mphamvu mofanana. Ma block a batri amachita chimodzimodzi - BMS imachotsa block yolephera, ndipo ma block otsalawo amapitiliza kutumikira DC basi.

Kukonza zinthu zosinthidwa nthawi yomweyo kumasintha kubwezerezedwanso kukhala kuchira mwachangu. Popeza mabuloko ali ndi ma interfaces ofanana, katswiri amalowa m'malo mwa chipangizo cholephera mkati mwa ola limodzi pogwiritsa ntchito zida zamanja, poyerekeza ndi kukonza fakitale kwa masiku ambiri kwa chipangizo cholumikizidwa cha monolithic. Izi zimachepetsa nthawi yokonza kuyambira masiku mpaka maola, zimakweza chitsimikizo cha kupezeka kwa magalimoto, ndikuchepetsa zinthu zosungiramo zinthu kukhala gulu laling'ono la mayunitsi osinthika omwe amagawidwa pa netiweki yonse. Kwa ogwira ntchito omwe ali ndi mgwirizano wautumiki pakukula kwa magalimoto pamsewu - komwe ola lililonse lopanda intaneti limataya ndalama ndipo dalaivala amataya chidaliro - uku ndiye kusiyana pakati pa katundu wogwiritsidwa ntchito ndi ngongole.

Kusinthasintha kwa Ntchito: Kapangidwe Kamodzi, Mafomu Ambiri
