I-China Tower isebenzisa iibhetri ze-lithium ukutshintsha iibhetri ze-lead-acid

HOPPT BATTERY analysis: New battery energy storage uses more and more lithium batteries, gradually replaces lead-acid batteries, and is more and more widely used in the energy storage market. The process of replacing lead-acid batteries in iron tower systems with lithium batteries has begun. Lithium iron phosphate batteries have low production costs and high cycle times. The core scenario of lithium battery applications in the communications market is base station backup power.

I-2020 Tower Communication Base Station iya kuthatha indawo ye-600-700,000 Towers yeebhetri zeLithium

Ukuzuza ekutshintshweni kwezikhululo ze-stock base, indawo yemarike ebanzi yogcino lwamandla onxibelelwano olulethwe yi-proporated enkulu ye-5G izikhululo zesiseko, kunye nokuthengiswa ngokukhawuleza kokugcinwa kwamandla kwicala lokuvelisa amandla, kwicala legridi, kunye necala lomsebenzisi, imakethi yokugcina amandla ebhetri ye-lithium ikhula ngokukhawuleza. Ukususela ekupheleni kukaJuni 2019, i-China Tower ifumene i-65,000 ye-5G yeemfuno zokwakha isiseko sesikhululo, kwaye kulindeleke ukuba ifumane i-100,000 ye-5G isiseko sokwakha isiseko kwiimfuno kulo nyaka.

1) Imakethe yebhetri yamandla: ukuthengiswa kwasekhaya kwezithuthi zamandla amatsha kulindeleke ukuba kufikelele kwi-7 yezigidi kwi-2025, kwaye ukuthengiswa kwamanye amazwe kulindeleke ukuba kudlule i-6 yezigidi ngo-2025. Ngo-2020, imfuno yebhetri yamandla asekhaya iya kuba malunga ne-85GWh. Ngo-2020, imfuno yebhetri yamandla aphesheya iya kuba malunga ne-90GWh. Indawo yoshishino lwebhetri yamandla iyaqhubeka nokukhula, kwaye imfuno yeebhetri zamandla kulindeleke ukuba ikhule malunga ne-50% ngo-2020.

2) Imakethi yebhetri engenamandla: Imakethi yokugcina amandla ebhetri ye-lithium okwangoku isebutsheni bayo. Ukutshintshwa kwe-lead-asidi yeebhetri ze-lithium kwizikhululo ezisisiseko zonxibelelwano yeyona ndawo ibalulekileyo yemfuno. Ngo-2018, iibhetri ze-lithium ezithatha indawo ye-lead-asidi ye-lead-asidi ziphelele kwi-120,000 yeenqaba, zisebenzisa malunga ne-1.5GWh yeebhetri ze-lithium. Iinqaba ezingamakhulu amathathu amawaka ziya kutshintshwa ngo-2019, zisebenzisa i-4-5GWh yeebhetri ze-lithium, kwaye izakhiwo ze-600,000-700,000 kulindeleke ukuba zitshintshwe kwi-2020, ecwangciselwe ukuba yi-8GWh. Zonke iinqaba ziya kutshintshwa malunga ne-25GWh, enkulu kakhulu.

3) Akukho mfuneko yokukhathazeka malunga nolwalathiso oluqhelekileyo lweebhetri ze-lithium: ingaba zizithuthi zamandla amatsha, iifowuni eziphathwayo ze-5G, iindawo zokugcina isikhululo sesiseko, kunye neebhetri zokugcina amandla, zonke zizimisele kwaye zikhula ngokuzinzileyo. Ngokuqhubela phambili kwe-Intanethi ephathwayo kunye ne-Intanethi yayo yonke into, ukusuka kwintambo ukuya kwi-wireless, iibhetri zeLithium okwangoku zezona zisombululo zamandla.

Yiyiphi imiqondiso ethunyelwa yinqaba yentsimbi xa isusa iibhetri ze-lead-asidi ngeebhetri ze-lithium?

Njengenkampani enkulu yenkonzo yonxibelelwano lweziseko ezingundoqo zenkonzo ebanzi, iTower Company inezikhululo ezisisiseko ezisisi-1.9 sezigidi. Kangangexesha elide, China Tower Corporation Limited isiseko isiseko unikezelo amandla ombane ziye zasebenzisa iibhetri lead-asidi, kwaye nyaka ngamnye ithenga malunga 100,000 iitoni iibhetri lead-asidi. Iibhetri ze-lead-asidi zinobomi obufutshane benkonzo, ukusebenza okuphantsi, kunye nentsimbi enzima. Ukuba zilahliwe, ziya kubangela ungcoliseko lwesibini kwindalo esingqongileyo ukuba aziphathwa ngokufanelekileyo.

Nangona kunjalo, xa kuthelekiswa neebhetri ze-lead-acid, iibhetri ze-lithium zineenzuzo zokuxinana kwamandla aphezulu kunye nobomi obude benkonzo. Ngesi sizathu, iNkampani ye-Tower yaqala ngo-2015 kwaye ngokulandelelana yenze iimvavanyo ze-cascading zokutshintsha iibhetri ze-lead-acid kunye neebhetri kwizikhululo ezisisiseko ezingaphezu kwe-3000 kumaphondo angama-12 kunye nezixeko. Ukhuseleko kunye nokuba nokwenzeka kobugcisa kunye noqoqosho lokusetyenziswa kwe-echelon kuqinisekisiwe.

Njengoko ukwakhiwa kwezikhululo zesiseko ze-5G zikhawuleza, imfuno yokugcina amandla e-lithium ibhetri iya kwanda kakhulu. I-China Tower ikukhuthaze ngokubanzi ukusetyenziswa kwe-cascade yeebhetri zamandla kwaye iyekile ukuthenga iibhetri ze-lead-asidi.

Okwesibini, ngenxa yokuba izikhululo zesiseko ze-5G zifuna i-layout-high-density layout, uphahla, kunye nezinye iindawo zinomthwalo omncinci wokuthwala umthwalo. Ngexesha elifanayo, xa iibhetri zokugcina amandla e-5G zithatha inxaxheba ekuchebeni okuphezulu kunye nokunciphisa iindleko, inani lokutshaja kunye nokukhutshwa liya kwandiswa kakhulu, kwaye inzuzo yexabiso eliphantsi lomjikelo opheleleyo. ibhetri ye-lithium iron phosphate iya kuba Ukukwazi ukudlala, kumandla adla umhlala-phantsi ibhetri ye-lithium izise amathuba abalulekileyo.

Kukho imfuno enkulu yokugcina amandla ebhetri ye-lithium kwizikhululo zesiseko se-tower, ezihambelana neempawu zokusetyenziswa okukhulu kweebhetri ezihlanganisiweyo. Ziya kuba zezona ndawo zisetyenziswayo kwiibhetri ezinamanqanaba; ukuba isiseko sonxibelelwano lwesiseko sonxibelelwano lweebhetri zitshintshwa, kwaye izikhululo ezitsha zonke zisebenzisa amandla ebhetri ye-cascade ibhetri, Iya kuzichitha ngo-2020. Ibhetri yamandla inokufunxa ngaphezu kwe-80%.

Isishwankathelo: I-China Tower isebenzisa iibhetri ze-lithium ukutshintsha iibhetri ze-lead-asidi, igcwalise izithuba kwiinkcukacha zobugcisa bokusetyenziswa kwe-cascading kwishishini lonxibelelwano lwasekhaya kunye nokuqhubela phambili iteknoloji yokusetyenziswa kwe-cascade.
