Tekanyo e nepahetseng ea hajoale ho Battery Management Systems (BMS) e beha meeli ea polokeho bakeng sa libeteri tsa lithium-ion ho pholletsa le likoloi tsa motlakase le lits'ebetso tsa polokelo ea matla. Lithuto tsa morao-rao tsa indasteri li senola hore ho feta 23% ea liketsahalo tsa mocheso oa betri li bakoa ke ho hoholeha ha li-circuits tsa ts'ireletso.
Tekanyetso ea hajoale ea BMS e netefatsa menyako ea bohlokoa bakeng sa tefiso e fetelletseng, ho tsoa ho feta tekano, le ts'ebetso ea ts'ireletso ea potoloho e khuts'oane joalo ka ha ho raliloe. Ha tekanyo e nepahetseng e theoha, libeteri li ka sebetsa ka nģ'ane ho lifensetere tse sireletsehileng tsa ts'ebetso - tse ka lebisang ho baleheng ha mocheso. Mokhoa oa calibration o kenyelletsa:
- Baseline netefatsoHo sebelisa li-multimeter tse netefalitsoeng ho netefatsa maqhubu a litšupiso khahlano le 'malo oa BMS. Lisebelisoa tsa ho lekanya boemo ba indasteri li tlameha ho fihlella ≤0.5% mamello.
- Phoso ea PhosoHo lokisa li-coefficients tsa "firmware" tsa boto ea ts'ireletso ha liphapang li feta litlhaloso tsa moetsi. BMS ea boemo ba likoloi hangata e hloka ≤1% ho kheloha hona joale.
- Netefatso ea Teko ea StressHo sebelisa lipotoloho tse etsisoang tsa mojaro ho tloha ho 10% -200% matla a lekantsoeng ho tiisa botsitso ba ho lekanya tlas'a maemo a sebele a lefats'e.
Dr. Elena Rodriguez, mofuputsi oa polokeho ea libeteri oa Munich Technical Institute o re: "BMS e sa lekanngoang e tšoana le mabanta a pholoso a nang le lintlha tse sa tsejoeng tse robehang. "Tekanyetso ea hona joale ea selemo le selemo ha ea lokela ho buisanoa bakeng sa lits'ebetso tsa matla a phahameng."
Mekhoa e metle e kenyelletsa:
- Ho sebelisa libaka tse laoloang ke mocheso (±2°C) nakong ea ho lekanya
- Ho netefatsa tumellano ea sensor ea Hall pele ho phetoho
- Ho ngola litokomane tsa mamello ea pele/ka morao-rao bakeng sa litsela tsa tlhahlobo
Maemo a ts'ireletso ea lefats'e ho kenyelletsa UL 1973 le IEC 62619 joale a laela lirekoto tsa tlhophiso bakeng sa phepelo ea betri ea grid-scale. Li-lab tsa tlhahlobo tsa batho ba bang li tlaleha 30% ea setifikeiti se potlakileng bakeng sa litsamaiso tse nang le nalane e netefalitsoeng ea ho lekanya.
