Ikiganiro kigufi ku ikoreshwa rya NTC Ubushyuhe bwa Sensor mu bikoresho byo kubika ingufu

Hamwe niterambere ryihuse ryikoranabuhanga rishya ryingufu, ipaki yububiko bwingufu (nka bateri ya lithium-ion, bateri ya sodium-ion, nibindi) ikoreshwa cyane mumashanyarazi, ibinyabiziga byamashanyarazi, ibigo byamakuru, nibindi bice. Umutekano nubuzima bwa bateri bifitanye isano rya hafi nubushyuhe bwo gukora.NTC (Negative Temperature Coefficient) ibyuma byubushyuhe, hamwe nubushobozi bwabo bwo hejuru hamwe nigiciro-cyiza, babaye kimwe mubice byingenzi byo kugenzura ubushyuhe bwa bateri. Hasi, turasesengura ibyifuzo byabo, ibyiza, nibibazo bivuye muburyo bwinshi.

I. Ihame ryakazi nibiranga NTC Ubushyuhe

1. Ihame shingiro
   Ubushuhe bwa NTC bwerekana kugabanuka gukabije kwubushyuhe uko ubushyuhe buzamuka. Mugupima impinduka zo guhangana, amakuru yubushyuhe arashobora kuboneka muburyo butaziguye. Umubano urwanya ubushyuhe ukurikiza formula:

RT=R0 ⋅eB(T1 -T0 1)

heRTNi ukurwanya ubushyuheT,R0 nuburyo bwo kurwanya ubushyuheT0, naBni ibikoresho bihoraho.

2. Ibyiza by'ingenzi
   • Ubushishozi bukabije:Imihindagurikire yubushyuhe buto iganisha ku guhinduka gukomeye, bigafasha gukurikirana neza.
   • Igisubizo cyihuse:Ingano ntoya hamwe nubushyuhe buke butanga igihe nyacyo cyo gukurikirana ihindagurika ryubushyuhe.
   • Igiciro gito:Ibikorwa byo gukura bikuze bishyigikira ibikorwa binini.
   • Ikirere Cyinshi:Urwego rusanzwe rukora (-40 ° C kugeza 125 ° C) rukubiyemo ibintu bisanzwe kuri bateri zibika ingufu.

II. Ibisabwa byo gucunga ubushyuhe mububiko bwamashanyarazi

Imikorere n'umutekano bya bateri ya lithium biterwa n'ubushyuhe bukabije:

• Ingaruka zo hejuru-Ubushyuhe:Kurenza urugero, gusohora cyane, cyangwa imiyoboro migufi irashobora gukurura ubushyuhe bwumuriro, biganisha kumuriro cyangwa guturika.
• Ingaruka zo hasi-Ubushyuhe:Kongera ubukonje bwa electrolyte ku bushyuhe buke bigabanya igipimo cyimuka cya lithium-ion, bigatuma gutakaza ubushobozi butunguranye.
• Ubushyuhe bumwe:Itandukaniro ryinshi ryubushyuhe muri moderi ya batiri yihutisha gusaza no kugabanya igihe cyose cyo kubaho.

Rero,igihe-nyacyo, kugenzura ingingo nyinshini umurimo wingenzi wa sisitemu yo gucunga bateri (BMS), aho sensor ya NTC igira uruhare runini.

III. Ubusanzwe Porogaramu ya NTC Sensors Mububiko bwa Bateri Yububiko

1. Kugenzura Ubushyuhe Bwakagari
   • Rukuruzi ya NTC yashyizwe hejuru ya buri selire cyangwa module kugirango ikurikirane neza ahantu hashyushye.
   • Uburyo bwo Kwishyiriraho:Byakoreshejwe ukoresheje ubushyuhe bwumuriro cyangwa ibyuma kugirango ubone guhuza cyane na selile.
2. Gukurikirana Imbere Imbere Ubushyuhe Uburinganire
   • Ibyuma byinshi bya NTC byoherejwe ahantu hatandukanye (urugero, hagati, impande) kugirango hamenyekane ubushyuhe bukabije cyangwa ubukonje bukabije.
   • Algorithms ya BMS itezimbere uburyo bwo kwishyuza / gusohora kugirango wirinde guhunga ubushyuhe.
3. Igenzura rya sisitemu
   • Amakuru ya NTC atera gukora / gukuraho sisitemu yo gukonjesha (gukonjesha ikirere / amazi yo gukonjesha cyangwa ibikoresho byo guhindura ibyiciro) kugirango ihindure imbaraga zo gukwirakwiza ubushyuhe.
   • Urugero: Gukora pompe ikonjesha amazi mugihe ubushyuhe burenze 45 ° C ukayifunga munsi ya 30 ° C kugirango ubike ingufu.
4. Gukurikirana Ubushyuhe bwibidukikije
   • Gukurikirana ubushyuhe bwo hanze (urugero, ubushyuhe bwo hanze hanze cyangwa imbeho ikonje) kugirango ugabanye ingaruka zibidukikije kumikorere ya bateri.

  

IV. Ibibazo bya tekiniki nibisubizo muri NTC Porogaramu

1. Igihe kirekire
   • Ikibazo:Kurwanya kurwanya bishobora kugaragara mubushyuhe bwo hejuru / ubushuhe bwibidukikije, bigatera amakosa yo gupima.
   • Igisubizo:Koresha NTCs yizewe cyane hamwe na epoxy cyangwa ibirahuri bikubiyemo, uhujwe na kalibrasi yigihe cyangwa kwikosora algorithms.
2. Ingorabahizi zo kohereza byinshi
   • Ikibazo:Gukoresha insinga bigenda byiyongera hamwe na sensor nyinshi kugeza mumajana mumapaki manini ya batiri.
   • Igisubizo:Koroshya insinga ukoresheje uburyo bwo kugura ibintu (urugero, ubwubatsi bwa bus bus) cyangwa ibyuma byoroshye bya PCB.
3. Ibiranga umurongo
   • Ikibazo:Umubano wa exponential resistance-ubushyuhe bisaba umurongo.
   • Igisubizo:Koresha indishyi za software ukoresheje imbonerahamwe yo kureba (LUT) cyangwa ikigereranyo cya Steinhart-Hart kugirango wongere BMS neza.

V. Inzira z'iterambere ry'ejo hazaza

1. Icyitonderwa Cyinshi na Digitisation:NTCs hamwe na interineti (urugero, I2C) igabanya guhuza ibimenyetso no koroshya igishushanyo cya sisitemu.
2. Gukurikirana Multi-Parameter Gukurikirana:Shyiramo voltage / ibyuma byifashishwa muburyo bwiza bwo gucunga ubushyuhe.
3. Ibikoresho bigezweho:NTC ifite intera yagutse (-50 ° C kugeza 150 ° C) kugirango ibone ibidukikije bikabije.
4. Kubungabunga AI-Gutwara Ibiteganijwe:Koresha imashini yiga gusesengura amateka yubushyuhe, guhanura ibisaza, kandi ushoboze kuburira hakiri kare.

VI. Umwanzuro

Ibyuma byubushyuhe bwa NTC, hamwe nigiciro cyabyo nigisubizo cyihuse, nibyingenzi mugukurikirana ubushyuhe mububiko bwa batiri bubika ingufu. Mugihe ubwenge bwa BMS butera imbere nibikoresho bishya, NTCs izarushaho kuzamura umutekano, igihe cyo kubaho, nuburyo bwiza bwa sisitemu yo kubika ingufu. Abashushanya bagomba guhitamo ibisobanuro bikwiye (urugero, B-agaciro, gupakira) kubisabwa byihariye, guhuza ibyerekezo bya sensor, no guhuza amakuru menshi-yamakuru kugirango yongere agaciro kabo.
