II. Litlhoko tsa Tsamaiso ea Mocheso ka har'a Lipakete tsa Battery ea ho Boloka Matla
Ts'ebetso le polokeho ea libeteri tsa lithium li itšetlehile haholo ka mocheso:
- Likotsi tsa Mocheso o Phahameng:Ho tjhaja ho feta tekano, ho ntsha metsi ho feta tekano, kapa di-circuits tse khutšoane ho ka etsa hore mocheso o balehe, o ka bakang mollo kapa ho phatloha.
- Liphello tsa Mocheso o Tlase:Ho eketseha ha viscosity ea electrolyte mocheso o tlase ho fokotsa litekanyetso tsa ho falla ha lithium-ion, ho baka tahlehelo ea matla ka tšohanyetso.
- Temperature Uniformity:Phapang e feteletseng ea mocheso ka har'a li-module tsa betri e potlakisa botsofali le ho fokotsa nako ea bophelo ka kakaretso.
Kahoo,nako ea sebele, ho hlahloba mocheso oa lintlha tse ngatake ts'ebetso ea bohlokoa ea Battery Management Systems (BMS), moo lisensara tsa NTC li bapalang karolo ea bohlokoa.
III. Lits'ebetso tse Tloaelehileng tsa Li-Sensors tsa NTC ho Lipakete tsa Battery tsa polokelo ea Matla
- Cell Surface Temperature Monitoring
- Li-sensor tsa NTC li kentsoe ka holim'a sele e 'ngoe le e' ngoe kapa mojule ho lekola libaka tse hotspots ka kotloloho.
- Mekhoa ea ho Kenya:E tsitsitseng ka ho sebelisa sekhomaretsi sa mocheso kapa li-brackets tsa tšepe ho netefatsa ho kopana ka thata le lisele.
- Internal Module Temperature Uniformity Monitoring
- Li-sensor tse ngata tsa NTC li sebelisoa libakeng tse fapaneng (mohlala, bohareng, mathōko) ho bona ho se leka-lekane ha mocheso kapa ho pholisa.
- Li-algorithms tsa BMS li ntlafatsa maqheka a ho tjhaja / ho lahla ho thibela ho baleha ha mocheso.
- Taolo ea Sistimi ea Pholiso
- Lintlha tsa NTC li etsa hore ho be le ts'ebetso / ho tima lits'ebetso tsa ho pholisa (ho pholisa moea / metsi kapa lisebelisoa tsa phetoho ea mohato) ho fetola ka mokhoa o matla ho qhala mocheso.
- Mohlala: Ho kenya pompo e pholileng ea metsi ha mocheso o feta 45°C le ho e koala ka tlase ho 30°C ho boloka matla.
- Ambient Temperature Monitoring
- Ho beha leihlo mocheso oa kantle (mohlala, mocheso oa kantle oa lehlabula kapa serame sa mariha) ho fokotsa litlamorao tsa tikoloho tšebetsong ea betri.
IV. Mathata a Tekheniki le Litharollo ho Likopo tsa NTC
- Botsitso ba nako e telele
- Phephetso:Resistance drift e ka etsahala tikolohong ea mocheso o phahameng / mongobo, e bakang liphoso tsa tekanyo.
- Tharollo:Sebelisa li-NTC tse tšepahalang haholo tse nang le epoxy kapa khalase e kentsoeng ka khalase, e kopantsoeng le ho lekanya nako le nako kapa mekhoa ea ho itokisa.
- Ho rarahana ha Multi-Point Deployment
- Phephetso:Ho rarahana ha lithapo ho eketseha ka li-sensor tse ngata ho isa ho tse makholo ka har'a lipakete tse kholo tsa betri.

V. Mekhoa ea Tsoelo-pele ea Bokamoso
- Nepahetseng e Phahameng le Digitization:Li-NTC tse nang le likhokahano tsa dijithale (mohlala, I2C) li fokotsa tšitiso ea matšoao le ho nolofatsa moralo oa sistimi.
- Multi-Parameter Fusion Monitoring:Kopanya li-sensor tsa motlakase / tsa hajoale bakeng sa maano a bohlale a taolo ea mocheso.
- Lisebelisoa tse tsoetseng pele:Li-NTC tse nang le mefuta e atolositsoeng (-50°C ho isa ho 150°C) ho fihlela litlhoko tse feteletseng tsa tikoloho.
- Tlhokomelo e Lebeletsoeng ea AI:Sebelisa ho ithuta ka mochini ho sekaseka nalane ea mocheso, ho bolela esale pele mekhoa ea botsofali, le ho fana ka litemoso tsa pele.
VI. Qetello
Li-sensor tsa mocheso oa NTC, ka katleho ea tsona le karabelo e potlakileng, li bohlokoa haholo bakeng sa ho lekola mocheso ka har'a lipakete tsa betri tsa polokelo ea matla. Ha bohlale ba BMS bo ntse bo ntlafala le lisebelisoa tse ncha li hlaha, li-NTC li tla ntlafatsa polokeho, nako ea bophelo le bokhoni ba lits'ebetso tsa polokelo ea matla. Baqapi ba tlameha ho khetha lintlha tse nepahetseng (mohlala, boleng ba B, sephutheloana) bakeng sa lits'ebetso tse ikhethileng, ho ntlafatsa ts'ebetso ea sensor, le ho kopanya lintlha tsa mehloli e mengata ho eketsa boleng ba tsona.
