Kev piav qhia: Lub charger voltage siab thaum pib lub cav. Lub charger voltage yuav tsum tsawg tshaj li lub alternator voltage kom them lub roj teeb. Tus qauv roj teeb automotive roj teeb yuav tsum qhia 12.6 V ntawm 35 ℃. Thaum lub cav khiav, nws yuav tsum qhia 13.7 V rau 14.7 V

Dab tsi yog qhov kev them nyiaj ib txwm muaj?

Qhov "ib txwm" them hluav taws xob ntawm daim ntawv thov raug yuav yog 13.9 txog 15.1 volts ntawm 77 degrees F. Tab sis ntawm 20 degrees F. qis dua xoom, lub them hluav taws xob yuav dhia siab li 14.9 txog 15.8 volts rau lub sijhawm luv luv. Ntawm lub cav kub ntawm ib hnub kub, qhov kev them nqi ib txwm yuav poob mus rau 13.5 txog 14.3 volts.

cranking voltage yog dab tsi?

Cranking Power

Feem ntau, raws li qhov kub thiab txias, xav tau ntau lub zog los pib lub cav. Txias cranking amps (CCA) yog qhov ntsuas ntsuas lub roj teeb lub zog cranking. Nws hais txog tus naj npawb ntawm cov amps lub roj teeb 12-volt tuaj yeem xa ntawm 0 ° F rau 30 vib nas this thaum tswj qhov hluav taws xob ntawm tsawg kawg 7.2 volts

Vim li cas qhov hluav taws xob hloov hluav taws xob them ntawm?

A alternator zoo yuav tsum tso tawm ntawm 13.5-14.5 volts. Kev nyuaj siab sim lub alternator - Muab ib qho load rau ntawm lub alternator los ntawm kev tig lub taub hau, xov tooj cua thiab cua txias. Qhov voltage yuav tsum nyob twj ywm siab nrog cov circuits ntawm.

Ntau npaum li cas volts yuav tsum tshwm sim ntawm lub tsheb them nyiaj thaum lub cav khiav thiab muaj qhov hloov pauv zoo?

13.5 Volts: Nrog lub cav khiav, lub tshuab hluav taws xob yuav tsum tso tawm "them hluav taws xob" uas yog hais txog ib qho hluav taws xob siab tshaj qhov hluav taws xob so, lossis txog 13.5-volts. Tus nqi them voltage nyob ntawm lub tsheb; Nws yuav qis li 13.2-volts lossis siab li 14.2-volts.
