Esimweni samanje sezinhlelo zamandla, ukugcinwa kwamandla kuyisici esibalulekile esiqinisekisa ukuhlanganiswa okungenamthungo kwemithombo yamandla avuselelekayo nokuqinisa ukuzinza kwegridi. Ukusetshenziswa kwayo kuhlanganisa ukukhiqizwa kwamandla, ukuphathwa kwegridi, kanye nokusetshenziswa kwabasebenzisi bokugcina, okwenza kube ubuchwepheshe obubalulekile. Lesi sihloko sihlose ukuhlola nokuhlola ukuhlukaniswa kwezindleko, isimo samanje sentuthuko, kanye namathemba esikhathi esizayo ezinhlelo zokugcina amandla ebhethri le-lithium-ion.
Ukwahlukaniswa Kwezindleko Zezinhlelo Zokugcina Amandla:
Isakhiwo sezindleko zezinhlelo zokugcina amandla siqukethe ikakhulukazi izakhi ezinhlanu: amamojula ebhethri, Izinhlelo Zokuphatha Amabhethri (i-BMS), amakhonteyina (ahlanganisa Izinhlelo Zokuguqula Amandla), izindleko zokwakha nezokufaka, kanye nezinye izindleko zokuklama nokulungisa amaphutha. Uma sibheka isibonelo sesistimu yokugcina amandla engu-3MW/6.88MWh efektri eSifundazweni saseZhejiang, amamojula ebhethri akha u-55% wezindleko eziphelele.
Ukuhlaziywa Okuqhathanisayo Kwezobuchwepheshe Bebhethri:
Uhlelo lokugcina amandla lwe-lithium-ion luhlanganisa abahlinzeki bemishini abaphezulu, abahlanganisi abaphakathi, kanye nabasebenzisi abaphansi. Imishini isukela kumabhethri, Izinhlelo Zokuphatha Amandla (EMS), Izinhlelo Zokuphatha Amabhethri (BMS), kuya Ezinhlelweni Zokuguqula Amandla (PCS). Abahlanganisi bahlanganisa abahlanganisi bezinhlelo zokugcina amandla kanye nezinkampani zobunjiniyela, ukuThenga, kanye noKwakha (EPC). Abasebenzisi bokugcina bahlanganisa ukukhiqizwa kwamandla, ukuphathwa kwegridi, ukusetshenziswa komsebenzisi wokugcina, kanye nezikhungo zokuxhumana/zedatha.
Ukwakheka kwezindleko zebhethri le-Lithium-ion:
Amabhethri e-lithium-ion asebenza njengezingxenye eziyisisekelo zezinhlelo zokugcina amandla kagesi. Njengamanje, imakethe inikeza ubuchwepheshe obuhlukahlukene bebhethri njenge-lithium-ion, i-lead-carbon, amabhethri okugeleza, kanye namabhethri e-sodium-ion, ngalinye linezikhathi zokuphendula ezihlukile, ukusebenza kahle kokukhipha, kanye nezinzuzo kanye nokushiyeka okulungiselelwe.
Izindleko zebhethri zakha ingxenye enkulu yezindleko zesistimu yokugcina amandla kagesi, ezifinyelela ku-67%. Izindleko ezengeziwe zifaka phakathi ama-inverter okugcina amandla (10%), izinhlelo zokuphatha amabhethri (9%), kanye nezinhlelo zokuphatha amandla (2%). Ngaphakathi kwezindleko zebhethri le-lithium-ion, izinto ze-cathode zithatha ingxenye enkulu cishe ku-40%, zilandelwa yizinto ze-anode (19%), i-electrolyte (11%), kanye ne-separator (8%).
Izitayela Nezinselele Zamanje:
Izindleko zamabhethri okugcina amandla ziye zabhekana nokwehla ngenxa yokwehla kwamanani e-lithium carbonate kusukela ngo-2023. Ukwamukelwa kwamabhethri e-lithium iron phosphate emakethe yokugcina amandla yasekhaya kuye kwakhuthaza kakhulu ukwehla kwezindleko. Izinto ezahlukahlukene ezifana nezinto ze-cathode kanye ne-anode, isihlukanisi, i-electrolyte, umqoqi wamanje, izingxenye zesakhiwo, nezinye ziye zabona izinguquko zamanani ngenxa yalezi zici.
Noma kunjalo, imakethe yamabhethri okugcina amandla ishintshe kusukela ekushodeni kwamandla kuya esimweni sokusabalalisa ngokweqile, okwandisa ukuncintisana. Abangenele abavela emikhakheni eyahlukene, okuhlanganisa abakhiqizi bamabhethri kagesi, izinkampani ze-photovoltaic, izinkampani ezisafufusa zamabhethri okugcina amandla, kanye nama-veteran asembonini asunguliwe, bangene empini. Lokhu kugcwala, kanye nokwanda kwamandla abadlali abakhona, kubeka engcupheni yokwakhiwa kabusha kwemakethe.
Isiphetho:
Naphezu kwezinselelo ezikhona zokunikezwa ngokweqile kanye nokuncintisana okukhulu, imakethe yokugcina amandla iyaqhubeka nokukhula kwayo okusheshayo. Njengoba ibhekwa njengendawo engaba yizigidigidi zamaRandi, inikeza amathuba okukhula okukhulu, ikakhulukazi phakathi kokukhuthazwa okuqhubekayo kwezinqubomgomo zamandla avuselelekayo kanye nemikhakha yezimboni neyezentengiselwano yaseShayina ekhuthele. Kodwa-ke, kulesi sigaba sokuncintisana ngokweqile kanye nokuncintisana okungapheli, amakhasimende angaphansi azofuna amazinga aphezulu ekhwalithi yamabhethri okugcina amandla. Abasanda kungena kumele babeke izithiyo zobuchwepheshe futhi bahlakulele amakhono ayisisekelo ukuze bachume kule ndawo eguquguqukayo.
Ngamafuphi, imakethe yaseShayina yamabhethri e-lithium-ion kanye nesitoreji samandla inikeza uchungechunge lwezinselele namathuba. Ukuqonda ukuhlukaniswa kwezindleko, izitayela zobuchwepheshe, kanye nokuguquguquka kwemakethe kubalulekile emabhizinisini azama ukuveza ubukhona obukhulu kulo mkhakha oshintsha ngokushesha.
