Magetsi a dzuwa m'misewu akhala gawo lofunika kwambiri pa zomangamanga zamakono za m'matauni, zomwe zimapereka njira yowunikira yosawononga chilengedwe komanso yotsika mtengo. Magetsi amenewa amadalira mabatire osiyanasiyana kuti asunge mphamvu zomwe zimagwidwa ndi ma solar panels masana.
1. Magetsi a mumsewu a dzuwa nthawi zambiri amagwiritsa ntchito mabatire a lithiamu iron phosphate:
Kodi batire ya lithiamu iron phosphate ndi chiyani?
Batire ya lithiamu iron phosphate ndi mtundu wa batire ya lithiamu-ion yomwe imagwiritsa ntchito lithiamu iron phosphate (LiFePO4) ngati cathode ndi carbon ngati anode. Voltage ya nominal ya selo limodzi ndi 3.2V, ndipo voltage yodulira charging ili pakati pa 3.6V ndi 3.65V. Pakuchaja, ma lithiamu ions amachoka ku lithiamu iron phosphate ndikuyenda kudzera mu electrolyte kupita ku anode, ndikulowa okha mu carbon items. Nthawi yomweyo, ma elekitironi amatulutsidwa kuchokera ku cathode ndikuyenda kudzera mu external circuit kupita ku anode kuti asunge bwino momwe mankhwala amachitira. Pakutulutsa, ma lithiamu ions amasuntha kuchokera ku anode kupita ku cathode kudzera mu electrolyte, pomwe ma elekitironi amasuntha kuchokera ku anode kupita ku cathode kudzera mu external circuit, kupereka mphamvu ku dziko lakunja.
Batire ya lithiamu iron phosphate ili ndi zabwino zambiri: mphamvu zambiri, kukula kochepa, kuchaja mwachangu, kulimba, komanso kukhazikika bwino. Komabe, ndi yokwera mtengo kwambiri pakati pa mabatire onse. Nthawi zambiri imathandizira ma charger a 1500-2000 deep cycle ndipo imatha kukhala zaka 8-10 ikagwiritsidwa ntchito mwachizolowezi. Imagwira ntchito mkati mwa kutentha kwakukulu kuyambira -40°C mpaka 70°C.
2. Mabatire a Colloidal omwe amagwiritsidwa ntchito kwambiri mu magetsi a mumsewu a dzuwa:
Kodi batri ya colloidal ndi chiyani?
Batire ya colloidal ndi mtundu wa batire ya lead-acid momwe gelling agent imawonjezeredwa ku sulfuric acid, zomwe zimapangitsa electrolyte kukhala ngati gel. Mabatire awa, omwe ali ndi electrolyte yawo ya gelled, amatchedwa mabatire a colloidal. Mosiyana ndi mabatire wamba a lead-acid, mabatire a colloidal amakula bwino pamagetsi amagetsi a kapangidwe ka electrolyte.
Mabatire a Colloidal sakukonzedwanso, zomwe zimathandiza kuthetsa mavuto okonzedwa nthawi zambiri okhudzana ndi mabatire a lead-acid. Kapangidwe kake kamkati kamalowa m'malo mwa electrolyte yamadzimadzi ya sulfuric acid ndi mtundu wa gelled, zomwe zimapangitsa kuti mphamvu yosungira isungidwe bwino, mphamvu yotulutsa madzi, magwiridwe antchito otetezeka, komanso moyo wautali, nthawi zina ngakhale kuposa mabatire a lithiamu-ion a ternary pankhani ya mtengo. Mabatire a Colloidal amatha kugwira ntchito kutentha kwa -40°C mpaka 65°C, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'madera ozizira. Amalimbananso ndi kugwedezeka ndipo angagwiritsidwe ntchito mosamala m'mikhalidwe yosiyanasiyana yovuta. Nthawi yawo yogwira ntchito ndi iwiri kapena kuposerapo poyerekeza ndi mabatire wamba a lead-acid.
3. Mabatire a NMC lithiamu-ion omwe amagwiritsidwa ntchito kwambiri mu magetsi amisewu a dzuwa:
Mabatire a NMC lithium-ion amapereka zabwino zambiri: mphamvu yeniyeni, kukula kochepa, komanso kuchaja mwachangu. Nthawi zambiri amathandizira machaji 500-800 a deep cycle, okhala ndi moyo wofanana ndi mabatire a colloidal. Kutentha kwawo kogwira ntchito ndi -15°C mpaka 45°C. Komabe, mabatire a NMC lithium-ion alinso ndi zovuta, kuphatikizapo kukhazikika pang'ono mkati. Ngati apangidwa ndi opanga osayenerera, pali chiopsezo cha kuphulika panthawi yochaja kwambiri kapena m'malo otentha kwambiri.
4. Mabatire a lead-acid omwe amagwiritsidwa ntchito kwambiri mu magetsi amisewu a dzuwa:
Mabatire a lead-acid ali ndi ma electrode opangidwa ndi lead ndi lead oxide, okhala ndi electrolyte yopangidwa ndi sulfuric acid solution. Ubwino waukulu wa mabatire a lead-acid ndi voltage yawo yokhazikika komanso mtengo wotsika. Komabe, ali ndi mphamvu yochepa, zomwe zimapangitsa kuti azikhala ndi voliyumu yayikulu poyerekeza ndi mabatire ena. Nthawi yawo yogwira ntchito ndi yochepa, nthawi zambiri imathandizira ma charges 300-500 deep cycle, ndipo amafunika kukonzedwa pafupipafupi. Ngakhale zovuta izi, mabatire a lead-acid akugwiritsidwabe ntchito kwambiri mumakampani opanga magetsi amisewu chifukwa cha phindu lawo.
Kusankha batire ya magetsi a mumsewu pogwiritsa ntchito mphamvu ya dzuwa kumadalira zinthu monga kugwiritsa ntchito mphamvu moyenera, nthawi yogwira ntchito, zosowa zosamalira, ndi mtengo wake. Mtundu uliwonse wa batire uli ndi ubwino wake wapadera, womwe umakwaniritsa zofunikira ndi mikhalidwe yosiyanasiyana, kuonetsetsa kuti magetsi a mumsewu okhala ndi mphamvu ya dzuwa amakhalabe njira yodalirika komanso yokhazikika yowunikira.
