- Roj teeb kub kev sib koom tes: Cov chaw them nqi sib txuas lus nrog lub tsheb BMS kom hloov kho cov nqi tam sim no (xws li, preheating nyob rau hauv txias txias los yog tam sim no txwv thaum kub kub).
4. Heat Pump HVAC thiab Cabin Climate Control
- Daim ntawv thov Scenario: Cov tub yees / cua sov mus rau hauv cov twj tso kua mis cua sov thiab kev tswj xyuas qhov kub thiab txias.
- Muaj nuj nqi:
- NTC Thermistor: Saib xyuas qhov kub thiab txias ntawm cov evaporators, condensers, thiab ambient ib puag ncig kom optimize lub tshav kub twj tso kua mis coefficient ntawm kev ua tau zoo (COP).
- Siab-Tsub Hybrid Sensors: Qee lub tshuab ua ke nrog cov twj tso kua mis siab kom tswj tsis tau cov tub yees txaus thiab lub zog compressor.
- Tus neeg nyob nyab xeeb: Pab kom tswj tau qhov kub thiab txias ntawm ntau lub ntsiab lus tawm tswv yim, txo kev siv hluav taws xob.
5. Lwm Cov Txheej Txheem Tseem Ceeb
- On-Board Charger (OBC): Saib xyuas qhov kub ntawm cov khoom siv hluav taws xob kom tiv thaiv kev puas tsuaj ntau dhau.
- Reducers thiab Transmissions: Saib xyuas lubricant kub kom ntseeg tau tias kev ua haujlwm zoo.
- Roj Cell Systems(piv txwv li, hauv cov tsheb hydrogen): Tswj cov roj cell txheej kub kom tsis txhob muaj cov membrane kom qhuav los yog condensation.
NTC vs. Lwm yam Sensors: Qhov zoo thiab kev txwv
