• Cov teebmeem ntawm qhov kub thiab txias:Ntxiv electrolyte viscosity ntawm qhov kub thiab txias txo lithium-ion migration tus nqi, ua rau poob peev xwm sai.
• Temperature Uniformity:Qhov kub thiab txias sib txawv nyob rau hauv cov roj teeb modules ceev kev laus thiab txo tag nrho lifespan.

Yog li,real-time, multi-point kub xyuasyog lub luag haujlwm tseem ceeb ntawm Battery Management Systems (BMS), qhov twg NTC sensors ua lub luag haujlwm tseem ceeb.

III. Cov ntawv thov ntawm NTC Sensors nyob rau hauv Energy Storage Battery Packs

1. Cell Surface Temperature Monitoring
   • NTC sensors raug ntsia rau ntawm qhov chaw ntawm txhua lub xov tooj ntawm tes lossis module los saib xyuas cov hotspots ncaj qha.
   • Installation Methods:Tsau siv cov nplaum nplaum los yog cov hlau nplaum los xyuas kom nruj kev sib cuag nrog cov hlwb.
2. Internal Module Temperature Uniformity Monitoring
   • Ntau NTC sensors raug xa mus rau ntawm qhov chaw sib txawv (xws li, nruab nrab, ntug) txhawm rau txheeb xyuas cov cua sov hauv cheeb tsam lossis qhov txias tsis txaus.
   • BMS algorithms optimize cov tswv yim them nqi / tso tawm kom tsis txhob muaj cua sov.
3. Txias System Control
   • NTC cov ntaub ntawv ua rau kev ua kom / tsis ua haujlwm ntawm cov tshuab cua txias (cua txias / kua txias lossis cov ntaub ntawv hloov pauv) kom hloov pauv cov cua sov.
   • Piv txwv li: Ua kom lub twj tso kua mis txias thaum kub tshaj 45 ° C thiab kaw nws qis dua 30 ° C kom txuag hluav taws xob.
4. Ambient Temperature Monitoring
   • Saib xyuas qhov kub thiab txias sab nraud (xws li, sab nraum zoov lub caij ntuj sov los yog lub caij ntuj no txias) kom txo tau qhov cuam tshuam ib puag ncig ntawm lub roj teeb ua haujlwm.
