KubSensor (PT1000 lossis NTC)ntawm EV Charging Connectors

----SENKU MACHINERY

Vim li cas thiaj xav tau Kub Sensors hauv EV Charging Connectors?

Txhawm rau txo qhov kev pheej hmoo ntawm overheating thaum lub tsheb hluav taws xob (EV) them, nws yog ib qho tseem ceeb los saib xyuas qhov kub thiab txias ntawm EV charging connectors (xws li plugs lossis sockets) nyob rau lub sijhawm, tshwj xeeb tshaj yog nyob rau hauv high-tso tawm tam sim no systems (feem ntau ntau dua los yog sib npaug rau. 60 A). Thaum qhov kub ntawm qhov sib txuas EV tshaj li qhov chaw pib, lub tshuab them nyiaj yuav txo qhov tso zis hluav taws xob lossis kaw tag nrho cov txheej txheem them nyiaj. Ob lub EV charging chaw nres tsheb thiab lub tsheb hluav taws xob tau nruab nrog cov tshuab ntsuas kub.

Piv txwv li, 250A CCS2 EV DC plug thaiv daim duab yuav zoo li no:

Hauv daim duab, koj tuaj yeem pom CCS2 ntsaws lub zog tiv tauj (DC + thiab DC-) raug saib xyuas los ntawm PT1000 qhov ntsuas kub. Txhua PT1000 sensor muaj ob lub xov hlau, sau tias T1, T2, T3, thiab T4:

· T1 thiab T2 saib xyuas DC + lub zog tiv tauj ntawm CCS2 ntsaws.

· T3 thiab T4 saib xyuas DC- fais fab kev sib cuag ntawm CCS2 ntsaws.

Txoj Cai Ua Haujlwm ntawm PT1000 Sensor

Qhov tsis kam ntawm PT1000 sensor hloov nrog kub. Raws li qhov kub thiab txias, qhov kev tiv thaiv tus nqi ntawm PT1000 kuj nce. Qhov kev sib raug zoo ntawm kev tiv thaiv thiab kub tuaj yeem siv los saib xyuas thiab tswj cov txheej txheem them nyiaj.

Lub sensor tus nqi kuj raug xa mus rau lub chaw nres tsheb them nyiaj. Thaum qhov kub thiab txias dhau lawm, lub kaw lus teb nrog NC (ib txwm kaw) lossis NO (ib txwm qhib) teeb liab, nyob ntawm qhov teeb tsa. Piv txwv li:

Thaum qhov kub thiab txias yog 0 degree, tus nqi PT 1000 kuj yog 1000Ω:

Yog tias teeb tsa tus nqi tsis kam mus rau qhov siab tshaj plaws ntawm 1000Ω, Yog tias qis dua 1000Ω, lub teeb liab tsis muaj, thiab thaum tus nqi tiv thaiv ntau dua 1000Ω, lub kaw lus yuav tau txais NC teeb liab.

Ntawm qhov tsis sib xws, Yog tias teeb tsa tus nqi tsis kam mus rau qhov siab tshaj plaws ntawm 1000Ω, Yog tias qis dua 1000Ω, lub teeb liab yog NC, thiab thaum tus nqi tiv thaiv ntau dua 1000Ω, lub kaw lus yuav tau txais NO signal.

Ntawm 0 degree, PT1000 kuj yog 1000Ω.

Yog tias lub kaw lus tau teeb tsa los kho cov nqi qis dua 1000Ω raws li TSIS TAU thiab siab dua 1000Ω raws li NC, lub kaw lus yuav teb raws li qhov ntsuas kub thiab qhov tsis kam tshaj 1000Ω.

Hloov pauv, yog tias lub kaw lus kho qhov tseem ceeb hauv qab 1000Ω li NC thiab siab dua 1000Ω raws li NO, cov cim yuav raug thim rov qab.

Nrhiav ntau qhov sib txawv EV charging connectors ntawm no!

Nco tseg:

· Cov nqi saum toj no yog cov lus piav qhia thiab tuaj yeem hloov kho raws li qhov yuav tsum tau ua hauv lub cev.

· Koj tuaj yeem teeb tsa tus nqi siab tshaj plaws raws li koj qhov kev xav tau tshwj xeeb thiab kev tsim qauv.
