Kukambitsirana Mwachidule pa Kugwiritsa Ntchito Ma Sensor a NTC Temperature mu Energy Storage Battery Packs

Ndi chitukuko chofulumira cha matekinoloje atsopano a mphamvu, mapaketi a batri osungira mphamvu (monga mabatire a lithiamu-ion, mabatire a sodium-ion, etc.) amagwiritsidwa ntchito mochulukira mu machitidwe amagetsi, magalimoto amagetsi, malo opangira deta, ndi zina. Chitetezo ndi moyo wa mabatire zimagwirizana kwambiri ndi kutentha kwawo.NTC (Negative Temperature Coefficient) masensa kutentha, ndi kukhudzika kwawo kwakukulu komanso kutsika mtengo, akhala chimodzi mwa zigawo zikuluzikulu zowunikira kutentha kwa batri. M'munsimu, tikufufuza momwe amagwiritsira ntchito, ubwino, ndi zovuta zawo kuchokera kumawonedwe angapo.

I. Mfundo Yogwira Ntchito ndi Makhalidwe a Zomverera za NTC Temperature

1. Mfundo Yoyambira
   Thermistor ya NTC imawonetsa kuchepa kwakukulu kwa kukana pamene kutentha kumakwera. Poyesa kusintha kwa kukana, deta ya kutentha ikhoza kupezedwa mosalunjika. Chiyanjano chokana kutentha chimatsatira njira iyi:

RT=R0⋅eB(T1 -T0 1)

kuRTndi kukana pa kutenthaT,R0 ndiye kukana kwatsatanetsatane pa kutenthaT0, ndiBndi zinthu zosasintha.

2. Ubwino waukulu
   • Kutengeka Kwambiri:Kusintha kwakung'ono kwa kutentha kumabweretsa kusiyanasiyana kwakukulu, kumathandizira kuyang'anira bwino.
   • Yankho Mwachangu:Kukula kocheperako komanso kutsika kwamafuta kumathandizira kutsata kusinthasintha kwanyengo munthawi yeniyeni.
   • Mtengo wotsika:Njira zopangira okhwima zimathandizira kutumizidwa kwakukulu.
   • Wide Temperature Range:Kusiyanasiyana kogwiritsiridwa ntchito (-40°C mpaka 125°C) kumakhudza zochitika zodziwika bwino zamabatire osungira mphamvu.

II. Zofunikira Zowongolera Kutentha mu Mphamvu Zosungira Battery Packs

Kuchita ndi chitetezo cha mabatire a lithiamu kumadalira kwambiri kutentha:

• Zowopsa Zakutentha Kwambiri:Kuchulukirachulukira, kutulutsa mopitilira muyeso, kapena mafupi afupikitsa kungayambitse kutha kwa kutentha, zomwe zimabweretsa moto kapena kuphulika.
• Kutentha Kwambiri:Kuwonjezeka kwa ma electrolyte viscosity pa kutentha kochepa kumachepetsa kusuntha kwa lithiamu-ion, kuchititsa kutaya mphamvu mwadzidzidzi.
• Kutentha Kufanana:Kusiyanasiyana kwa kutentha mkati mwa ma module a batri kumathandizira kukalamba ndikuchepetsa moyo wonse.

Choncho,nthawi yeniyeni, yowunikira kutentha kwamitundu yambiriNdi ntchito yovuta ya Battery Management Systems (BMS), pomwe masensa a NTC amagwira ntchito yofunika kwambiri.

III. Kugwiritsa Ntchito Masensa a NTC mu Mphamvu Zosungira Battery Packs

1. Kuwunika Kutentha kwa Ma cell Surface Temperature
   • Masensa a NTC amayikidwa pamwamba pa selo kapena gawo lililonse kuti ayang'ane malo omwe ali ndi malo ambiri.
   • Njira zoyikira:Kukhazikika pogwiritsa ntchito zomatira zotentha kapena zomangira zachitsulo kuti zitsimikizire kulumikizana kolimba ndi ma cell.
2. Internal Module Temperature Uniformity Monitoring
   • Masensa angapo a NTC amayikidwa m'malo osiyanasiyana (mwachitsanzo, pakati, m'mphepete) kuti azindikire kutenthedwa kwapadziko lonse kapena kusalinganika koziziritsa.
   • Ma algorithms a BMS amawongolera njira zolipirira / zotulutsa kuti mupewe kuthawa kwamafuta.
3. Kuzizira System Control
   • Deta ya NTC imayambitsa kuyambitsa/kuzimitsa makina ozizirira (kuzizira kwa mpweya/zamadzimadzi kapena zinthu zosinthira gawo) kuti zisinthe mwachangu kutulutsa kutentha.
   • Chitsanzo: Kutsegula pampu yozizirira yamadzimadzi ikatentha kuposa 45°C ndikuyitseka pansi pa 30°C kuti musunge mphamvu.
4. Kuwunika Kutentha kwa Ambient
   • Kuyang'anira kutentha kwakunja (monga kutentha kunja kwachilimwe kapena kuzizira) kuti muchepetse kuwononga chilengedwe pakugwira ntchito kwa batri.

  

IV. Mavuto Aukadaulo ndi Mayankho mu Mapulogalamu a NTC

1. Kukhazikika Kwanthawi Yaitali
   • Chovuta:Kusunthika kwamphamvu kumatha kuchitika m'malo otentha kwambiri / chinyezi, zomwe zimapangitsa kuti pakhale zolakwika.
   • Yankho:Gwiritsani ntchito ma NTC odalirika kwambiri okhala ndi epoxy kapena encapsulation ya magalasi, kuphatikiza kusanja kwanthawi ndi nthawi kapena ma aligorivimu odziwongolera.
2. Kuvuta kwa Multi-Point Deployment
   • Chovuta:Kuvuta kwa ma waya kumachulukirachulukira ndi masensa ambiri mpaka mazana ambiri m'mapaketi akulu a batri.
   • Yankho:Yang'anirani mawaya osavuta pogwiritsa ntchito ma module ogawa (monga, kamangidwe ka mabasi a CAN) kapena masensa osinthika a PCB-integrated.
3. Makhalidwe Osatsata
   • Chovuta:Ubale wa exponential resistance-temperature umafuna mzere.
   • Yankho:Ikani chipukuta misozi pogwiritsa ntchito ma lookup tables (LUT) kapena Steinhart-Hart equation kuti muwonjezere kulondola kwa BMS.

V. Tsogolo la Chitukuko

1. Kulondola Kwambiri ndi Digitization:Ma NTC okhala ndi mawonekedwe a digito (mwachitsanzo, I2C) amachepetsa kusokoneza kwa ma siginecha ndikusintha kamangidwe kadongosolo.
2. Multi-Parameter Fusion Monitoring:Phatikizani masensa amagetsi / apano kuti mugwiritse ntchito njira zanzeru zowongolera kutentha.
3. Zida Zapamwamba:Ma NTC okhala ndi milingo yotalikirapo (-50°C mpaka 150°C) kuti akwaniritse zofuna za chilengedwe.
4. Kusamalira Zolosera Zoyendetsedwa ndi AI:Gwiritsani ntchito makina ophunzirira kusanthula mbiri ya kutentha, kulosera za ukalamba, ndi kuyatsa machenjezo oyambilira.

VI. Mapeto

Zomverera za kutentha za NTC, zotsika mtengo komanso kuyankha mwachangu, ndizofunikira kwambiri pakuwunika kutentha m'mapaketi osungira mphamvu. Pamene nzeru za BMS zikupita patsogolo komanso zida zatsopano zikutuluka, ma NTC apititsa patsogolo chitetezo, moyo wautali, ndi mphamvu zamakina osungira mphamvu. Okonza ayenera kusankha zoyenerera (monga B-mtengo, kulongedza) kwa ntchito zinazake, kukhathamiritsa kakhazikitsidwe ka sensa, ndi kuphatikizira deta yamitundu yambiri kuti iwonjezere mtengo wake.
