NTC thermistors uye mamwe ma sensors ekushisa (eg, thermocouples, RTDs, digital sensors, nezvimwewo) inoita basa rinokosha mukugadzirisa kupisa kwemotokari yemotokari yemagetsi, uye inonyanya kushandiswa pakuongorora nguva chaiyo uye kutonga kwekushisa kuti ive nechokwadi chekushanda uye kushanda kwakachengeteka kwemotokari. Izvi zvinotevera maitiro avo makuru ekushandisa uye mabasa.
1. Thermal Management of Power Batteries
- Application Scenario: Kutarisisa tembiricha uye kuenzanisa mukati mebhatiri mapaketi.
- Mabasa:
- NTC Thermistors: Nekuda kwemutengo wakaderera uye compact size, maNTC anowanzo kuisirwa munzvimbo dzakakosha mumamodule ebhatiri (semuenzaniso, pakati pemaseru, pedyo nematanho anotonhodza) kutarisa kudziya kwenzvimbo munguva chaiyo, kudzivirira kupisa kubva pakuwedzeredza / kuburitsa kana kuderedzwa kwekuita pakudziya kwakaderera.
- Zvimwe Sensors: High-precision RTDs kana dhijitari sensors (semuenzaniso, DS18B20) inoshandiswa mune mamwe mamiriro ekutarisa yakazara bhatiri tembiricha kugovera, kubatsira iyo BMS (Battery Management System) mukugadzirisa kuchaja / kuburitsa nzira.
- Safety Protection: Inokonzeresa kutonhodza masisitimu (mvura/kutonhodza kwemhepo) kana kuderedza simba rekuchaja panguva yekupisa kusina kujairika (semuenzaniso, maprecursors ekutiza kwekupisa) kuderedza njodzi dzemoto.
2. Motokari uye Simba Electronics Kutonhora
- Application Scenario: Kutarisisa tembiricha yemota windings, inverters, uye DC-DC converters.
- Mabasa:
- NTC Thermistors: Yakaiswa mumotokari stators kana magetsi emagetsi modules kuti ikurumidze kupindura kushanduka kwekushisa, kudzivirira kurasikirwa kwekushanda kana kukanganisa kwekudzivirira nekuda kwekupisa.
- High-Temperature Sensors: Nzvimbo dzepamusoro-tembiricha (semuenzaniso, pedyo nesilicon carbide magetsi emagetsi) anogona kushandisa rugged thermocouples (semuenzaniso, Type K) kuvimbika pasi pemamiriro akanyanya.
- Dynamic Control: Inogadzirisa kutonhora kuyerera kana kumhanya kwefan zvichibva pane tembiricha mhinduro kuti ienzanise kutonhora kutonhora uye kushandiswa kwesimba.
3. Kuchaja System Thermal Management
- Application Scenario: Kutarisisa tembiricha panguva yekuchaja nekukurumidza kwemabhatiri uye yekuchaja nzvimbo.
- Mabasa:
- Kuchaja Port Monitoring: NTC thermistors inoona tembiricha pakuchaja plug yekubata mapoinzi kudzivirira kupisa kunokonzerwa nekunyanya kubata kuramba.
- Battery Temperature Coordination: Zviteshi zvekuchaja zvinotaurirana neBMS yemotokari kuti igadzirise kuchaja ikozvino (semuenzaniso, preheating mumamiriro ekutonhora kana kudzikamisa kwazvino panguva yekupisa kwakanyanya).
4. Kupisa Pombi HVAC uye Cabin Climate Control
- Application Scenario: Refrigeration/heating cycles mu heat pump systems uye cabin tembiricha mutemo.
- Mabasa:
- NTC Thermistors: Tarisa tembiricha ye evaporator, condensers, uye ambient nharaunda kuti ugone kukwidziridza pombi yekupisa yekushanda (COP).
- Pressure-Temperature Hybrid Sensors: Mamwe masisitimu anobatanidza kudzvanywa sensors kuti aite zvisina kunanga kuyerera kwefiriji uye compressor simba.
- Mugari Nyaradzo: Inogonesa kudzora tembiricha yezoned kuburikidza neakawanda-point mhinduro, kuderedza kushandiswa kwesimba.
5. Mamwe Maitiro Akakosha
- Pa-Board Charger (OBC): Inotarisa tembiricha yezvikamu zvemagetsi kudzivirira kuwandisa kukuvadzwa.
- Reducers uye Transmissions: Monitors lubricant tembiricha kuti ive nechokwadi kushanda zvakanaka.
- Fuel Cell Systems(semuenzaniso, mumotokari dzehydrogen): Inodzora tembiricha yemafuta masero kudzivirira kuomeswa kwemembrane kana condensation.
NTC vs. Mamwe maSensors: Advantages uye Limitations
| Sensor Type | Zvakanakira | Kuganhurirwa | Typical Applications |
|---|---|---|---|
| NTC Thermistors | Mutengo wakaderera, mhinduro inokurumidza, compact size | Nonlinear yakabuda, inoda calibration, shoma tembiricha renji | Battery modules, motor windings, kuchaja zviteshi |
| RTDs (Platinum) | High precision, linearity, kugadzikana kwenguva refu | Mutengo wepamusoro, mhinduro inononoka | High-accuracy bateri monitoring |
| Thermocouples | High-tembiricha kushivirira (kusvika 1000 ° C+), nyore dhizaini | Inoda kutonhora-junction muripo, chiratidzo chisina simba | High-tembiricha nzvimbo mumagetsi emagetsi |
| Digital Sensors | Yakananga dhijitari kubuda, ruzha kusadzivirirwa | Mutengo wepamusoro, bandwidth shoma | Kugoverwa kwekutarisa (semuenzaniso, kabhini) |
Future Trends
- Smart Integration: Sensors dzakasanganiswa neBMS uye domain controllers yekufungidzira kwekupisa kwekutonga.
- Multi-Parameter Fusion: Inosanganisa tembiricha, kudzvanywa, uye humidity data kukwirisa kushanda kwesimba.
- Advanced Materials: Thin-film NTCs, fiber-optic sensors yekusimudzira yakakwirira-tembiricha kuramba uye EMI kusadzivirirwa.
Summary
NTC thermistors inoshandiswa zvakanyanya muEV thermal management yeakawanda-point tembiricha yekutarisa nekuda kwemutengo-kushanda uye nekukurumidza kupindura. Mamwe masensor anoatsigira mune yakakwirira-chaiyo kana yakanyanyisa-yemamiriro ekunze. Synergy yavo inovimbisa kuchengetedzeka kwebhatiri, kushanda zvakanaka kwemotokari, kunyaradza kabhini, uye yakawedzera chikamu chehupenyu, ichigadzira hwaro hwakakosha hwekushanda kwakavimbika kweEV.
