Amabhethri angenye yezingxenye ezibaluleke kakhulu ze-Electrochemical Energy Storages. Ngokwehliswa kwezindleko zebhethri le-lithium kanye nokwenza ngcono ubuningi be-lithium yebhethri le-Lithium Energy density, ukuphepha kanye nesikhathi sokuphila, ukugcinwa kwamandla nakho sekungenile kuzinhlelo zokusebenza ezinkulu. Le ndatshana izokusiza uqonde ukugcinwa kwamandla emikhakheni eminingana ebalulekile yeIbhethri le-Lithium.
01
Umthamo webhethri we-Lithium
ibhethri le-lithiumAmandla kungenye yezinkomba zokusebenza okubalulekile kokulinganisa ukusebenza kwebhethri le-lithium. Umthamo webhethri le-lithium uhlukaniswe umthamo olinganiselwe kanye namandla wangempela. Ngaphansi kwemibandela ethile (izinga lokuphuma, izinga lokushisa, ukunqanyulwa kwamandla kagesi, njll.) Amayunithi ajwayelekile wethamo nguMah no-1000mah. Ukuthatha i-48V, ibhethri le-lithium le-lithium njengesibonelo, umthamo webhethri we-lithium ngu-48V × 50 50h = 2400Wh, okungama-2.4 kilowatt amahora.
02
isilinganiso se-lithium sokukhipha ibhethri
C isetshenziselwa ukukhombisa ukushaja kwebhethri ye-lithium kanye nenani lokukhipha umthamo. Ukushaja nokukhipha izinga = ukushaja futhi kokwehla kwamandla akhona / alinganiselwe. Isibonelo: Lapho ibhethri le-lithium elinekhono elilinganiselwe le-100AH liyakhishwa ku-50a, izinga lokucima kwalo lingu-0.5c. I-1C, 2C, kanye ne-0.5c amanani entengo e-lithium ebala lebhethri, eliyisilinganiso sokukhipha ijubane. Uma umthamo osetshenzisiwe ukhishwa ngehora eli-1, ibizwa ngokuthi yi-1C yokuphuma; Uma ikhishwa emahoreni ama-2, ibizwa nge-1/2 = 0.5c det. Ngokuvamile, umthamo webhethri le-lithium angatholwa ngemisinga ehlukene yokuphuma. Ibhethri le-lewitium le-24Ah, ukukhipha i-1c kwamanje kungama-24a kanti ukukhipha u-0.5c kwamanje kungu-12a. Okukhulayo kokukhishwa kwamanje. Isikhathi sokukhipha sifushane futhi. Imvamisa lapho ukhuluma ngesilinganiso sohlelo lokugcina amandla, kuvezwa ngamandla aphezulu wohlelo / umthamo wesistimu (kw / kWh). Isibonelo, isilinganiso sesiteshi samandla esitoreji samandla singama-500kw / 1MWh. Lapha ama-500kW abhekisela ekushajaneni okuphezulu nokukhishwa kohlelo lokugcina amandla. Amandla, 1mwh abhekisela kumthamo wesistimu wesiteshi samandla. Uma amandla ekhishwa ngamandla alinganiselwe ka-500kw, umthamo wesiteshi samandla ukhishwe emahoreni ama-2, futhi izinga lokukhukhuzayo lingu-0.5c.
03
I-SOC (isimo sokukhokhisa) isimo sokukhokhisa
Isimo sebhethri le-lithium ngesiNgisi siyisimo sokukhokhisa, noma i-soc Forful. Kusho isilinganiso se-racity esele yebhethri le-lithium ngemuva kokuthi isetshenziselwe isikhathi esithile noma ishiywe engasetshenziswanga isikhathi eside namandla ayo esimweni esisebenza ngokugcwele. Imvamisa kuvezwa njengephesenti. Kalula nje, kungumthamo osele webhethri le-lithium. amandla.
04
I-DOD (ukujula kokukhishwa) ukujula kokukhululwa
Ukujula kokukhululwa (i-DOD) kusetshenziselwa ukukala amaphesenti phakathi kwe-lithium yebhethri yokuphuma kwebhethri kanye ne-lithium ibhethri elilinganiselwe. Ibhethri le-lithium elifanayo, ukujula kwe-DOD kwe-DOD kuyinto elingana ngaphakathi kwempilo ye-lithium ye-lithium yebhethri yebhethri. Ukujula kokujula kokukhishwa, okufushane kwempilo ye-lithium yebhethri yebhethri. Ngakho-ke, kubalulekile ukulinganisa isikhathi esidingekayo sebhethri le-lithium ngesidingo sokuthola impilo ye-lithium ye-lithium yebhethri yebhethri.
Uma ushintsho ku-SOC kusuka ngokuphelele kungenalutho ngokuphelele ukuthi lukhokhiswe ngokugcwele luqoshwe njengo-0 ~ 100%, kungcono ukwenza umsebenzi webhethri we-lithium ngamunye, futhi kungenzeka ukuthi usebenze ngezansi 10%. Kuzobe kukhishwe ngaphezulu futhi okunye ukusabela kwamakhemikhali okungaphenduki kuzokwenzeka, okuzothinta impilo yebhethri ye-lithium.
05
I-SOH (Isimo Sezempilo) Isimo Sezempilo se-Lithium
I-SOH (isimo sempilo) ikhombisa ikhono lamanje le-Lithium Ikhono lokugcina amandla kagesi ahlobene nebhethri elisha le-lithium. Kusho isilinganiso samandla we-Lithium webhethri aphelele ebhethri lamanje kumandla we-Lithium ebhethri eligcwele. Ukuchazwa kwamanje kwe-SOH kuboniswa ikakhulukazi ezintweni eziningana ezifana namandla, ugesi, ukumelana kwangaphakathi, izikhathi zomjikelezo namandla aphezulu. Amandla kanye namandla asetshenziswa kakhulu.
Ngokuvamile, lapho umthamo webhethri we-lithium (i-SOH) ehla afinyelela kuma-70% kuya ku-80%, kungabhekwa ukuthi afinyelele ku-EOL (ukuphela kwempilo yebhethri ye-lithium). I-SOH iyinkomba echaza isimo sezempilo samanje sebhethri le-lithium, kanti i-EOL ikhombisa ukuthi ibhethri le-lithium lifinyelele ekugcineni kwempilo. Idinga ukushintshwa. Ngokuqapha inani le-SOH, isikhathi sebhethri le-lithium ukufinyelela i-EOL lingabikezelwa futhi ukulungiswa okuhambisanayo kanye nokuphathwa kungenziwa.
