Ukusebenza kwebhetri ngumsebenzi weqondo lobushushu. Zonke iiseli ze-lithium-ion zisebenza ngokufanelekileyo ngaphakathi kwebhanti yokushisa emxinwa-ngokuqhelekileyo phakathi kwe-15 ° C kunye ne-35 ° C - kwaye ukutenxa kulo naliphi na icala kuthobisa ukusebenza, ukukhawulezisa ukuguga, kunye nokwandisa ingozi yokhuseleko. Kwiiprojekthi zokugcina amandla ezorhwebo kunye nezoshishino, uzinzo lwe-thermal alukho nje inkcazo yobugcisa; ichaphazela ngqo imbuyekezo kutyalo-mali, ukufumaneka kwenkqubo, kunye neendleko zokusebenza zexesha elide. A inkqubo yokugcina amandla okupholisa ulwelo ijongana nalo mceli mngeni ngokukhuthala ukugcina amaqondo obushushu afanayo kuzo zonke iiseli zebhetri, kungakhathaliseki iimeko zangaphandle okanye amaxabiso okukhutshwa kwentlawulo. Ukuqonda ukuba kutheni uzinzo lwe-thermal lubalulekile kunceda abanini beprojekthi bathethelele ukhetho lwetekhnoloji yokupholisa ekumgangatho ophezulu kunezinye ezingabizi kakhulu kodwa zingasebenzi kakuhle.

Iindleko zokungazinzi kweThermal

Ngaphandle kolawulo olululo lwe-thermal, iinkqubo zebhetri zifumana iingxaki ezininzi ezinxulumeneyo. Ngethuba lemijikelezo yokukhutshwa kwezinga eliphezulu, ukuchasana kwangaphakathi kuvelisa ukushisa okugxininiswe kwii-terminals zeseli kunye nabaqokeleli bangoku. Kwiinkqubo ezipholileyo zomoya, obu bushushu buqokelelana ngokungalinganiyo, budala iindawo ezishushu ezinokuthi zidlule kwimida ekhuselekileyo nge-10 ° C okanye ngaphezulu. Amaqondo obushushu aphakamileyo akhawulezisa ukukhula kwe-solid-electrolyte interphase kwi-anodes, kudla i-lithium esebenzayo kunye nokunciphisa ngokusisigxina umthamo. Umgaqo ocatshulwe ngokubanzi kubunjineli bebhetri ubambe ukuba rhoqo nge-10°C yonyuka ngaphezu kweqondo lobushushu elilelona lilelona lifanelekileyo linciphisa ubomi bekhalenda. Ngaphaya koko, iqondo lobushushu kwipakethi libangela ukuba ezinye iiseli ziwohloke ngokukhawuleza kunezinye, zenza ukungalingani okunyanzela inkqubo ukuba iyeke ukukhupha xa eyona seli ibuthathaka ifikelela kumbane wayo wokunqamla. Inkqubo yokugcina amandla okupholisa ulwelo ithintela le miba ngokujikelezisa isisipholisi kwiipleyiti ezibandayo ezisecaleni kweseli nganye, ikhupha ubushushu kanye apho buveliswe khona. Isiphumo kukuba a 261kWh ESS ehambisa amandla ayo alinganisiweyo unyaka nonyaka ngaphandle kokuthotywa kwangaphambili.

Njani ukupholisa kolwelo kuNxibelela ngokuFaneka koBubushushu obuPhezulu

Inzuzo echazayo yenkqubo yokugcina amandla okupholisa ulwelo ayikona nje ukuncitshiswa ngokupheleleyo kobushushu kodwa ukungaguquguquki kobushushu. Izipholisi ezisekwe emanzini ziphantse zibe ngama-25 ubukhulu bobushushu obukhethekileyo bomoya kunye ne-thermal conductivity ephezulu kakhulu. Oku kuthetha ukuba ulwelo olubambeneyo lunokususa ubushushu obuninzi kunye nomthamo wokuqukuqela okuncinci kunye nokutsalwa kwamandla eparasitiki asezantsi. Kwi-261kWh ESS eyilwe kakuhle, umehluko weqondo lokushisa phakathi kweseli efudumeleyo kunye nepholileyo ihlala kwi-± 1.5 ° C okanye ingcono-xa kuthelekiswa ne-± 5 ° C ukuya ku-± 8 ° C kwiikhabhinethi ezipholile emoyeni. Oku kufana kuqinisekisa ukuba zonke iiseli zikhula kwizinga elifanayo, ukwandisa umthamo osebenzisekayo kunye nokulibazisa imfuno yokungenelela kokulondoloza. Kubasebenzi bezorhwebo abaqhuba imijikelo yokutsheva encopho yemihla ngemihla, oko kuhambelana kuguqulela ngokuthe ngqo kulondolozo oluqikelelwayo kwiintlawulo zemfuno.

Ukuzinza kwe-Thermal kwenza ukuba kuSebenziswe okuPhakamileyo kwiiNdawo eziQhelekileyo

Iikhabhathi zokugcina amandla zangaphandle zijongana neemeko ezingaphaya kwamandla ambient—ubushushu behlobo obutshisayo, ingqele engaphantsi kobusika, kunye nokutshintsha kwemini ebusuku. Iinkqubo zokupholisa umoya ziyasokola kumaza obushushu kuba zixhomekeke kumoya ongqonge indawo onokuthi uphantse ube shushu njengeebhetri ngokwazo. Umthamo wokupholisa uyehla njengoko ubushushu bendawo bukhula. Inkqubo yokugcina amandla okupholisa ulwelo ihlukanisa ulawulo lobushushu ukusuka kwiimeko ezingqongileyo. Ulwelo olululwelo luyala ubushushu ngeradiyetha, kodwa isisipholisi ngokwaso sigcina ubushushu obuzinzileyo kungakhathaliseki ukuba umoya wangaphandle unjani. Kwiimozulu ezibandayo, inkqubo inokufudumeza iibhetri ngaphambi kokutshaja, ukuthintela i-lithium plating kunye nokwandisa ubomi bomjikelezo. Oku komelela kokusingqongileyo kwenza i-261kWh ESS ilungele ukusasazwa phantse kuwo nawuphi na ummandla ngaphandle kokuthotywa kokusebenza. Ukongeza, iilophu zolwelo ezitywiniweyo zithintela uthuli, ityuwa, kunye nokufuma ekungcoliseni amagumbi ebhetri-inzuzo ebalulekileyo yofakelo lwaselunxwemeni okanye kwimizi-mveliso.

Ukuzinza kweThermal njengeSigqibo seShishini

Kulo naluphi na utyalo-mali lokugcina amandla orhwebo okanye kwimizi-mveliso, ukuzinza kwe-thermal ayisiyonto yobuhle bobunjineli-yinto eyimfuneko yezemali. Ulawulo olungcono lobushushu luthetha ubomi obude bebhetri, ukusetyenziswa okuphezulu okusebenzisekayo, kunye neziganeko ezimbalwa zolungiso kubomi benkqubo. Nge I-Wener, i-High ROI 261kWh i-Liquid yokuPholisa i-C&I ESS IKhabhinethi inikezela kanye loo nto. Le khabhinethi yokugcina amandla yangaphandle yinkqubo yonke-in-one enebhetri, i-BMS, i-AC-DC converter, ukukhuselwa kwe-thermal, kunye nokukhuselwa komlilo. Inkqubo yayo ephezulu yokupholisa ulwelo iqinisekisa ibhalansi ye-thermal ephezulu, ubomi obude bebhetri, kunye nokusebenza okuzinzileyo phantsi kweemeko ezahlukeneyo zokusingqongileyo. Ngenkxaso ye-Modbus, i-IEC104, kunye ne-MQTT yokudibanisa lula, i-261kWh ESS evela kwi-Wenergy idibanisa ukuzinza kwe-thermal kunye noqhagamshelwano oluhlakaniphile. Xa iprojekthi yakho ifuna inkqubo yokugcina amandla okupholisa ulwelo eyandisa imbuyekezo ngolawulo oluthembekileyo lwe-thermal, i-Wenergy ibonelela ngesisombululo esakhelwe ukuhlala.
