Ukadaulo Watsopano Wopangira Chotenthetsera cha PTC Wasintha Kutentha kwa Magalimoto Amagetsi

Mu chitukuko chachikulu cha makampani opanga magalimoto amagetsi (EV), chotenthetsera chatsopano cha PTC (positive temperature coefficient) chapangidwa chomwe chikulonjeza kusintha kwambiri magwiridwe antchito ndi magwiridwe antchito a makina otenthetsera oziziritsa magetsi a EV. Chodziwika kuti chotenthetsera cha HV PTC, ukadaulo wotsogola uwu udzasintha momwe magalimoto amagetsi amatenthetsera chotenthetsera magetsi, zomwe zimabweretsa zabwino zambiri kwa opanga magalimoto amagetsi ndi ogula.

Magalimoto amagetsi achikhalidwe amadalira ma heater achikhalidwe a PTC kuti atenthetse choziziritsira mu dongosolo. Ma heater awa amagwiritsa ntchito ma resistors kuti apange kutentha magetsi akadutsa mwa iwo, koma amatentha pang'onopang'ono ndipo nthawi zambiri sagwira ntchito bwino. Izi zimapangitsa kuti kutentha kukhale kotalikirapo komanso kuti mphamvu zigwiritsidwe ntchito kwambiri, zomwe zimakhudza kwambiri magwiridwe antchito a galimoto yamagetsi.

Komabe, chotenthetsera chatsopano cha PTC chokhala ndi mphamvu yapamwamba chili ndi zabwino zingapo zazikulu kuposa zotenthetsera zachikhalidwe za PTC. Choyamba, chimagwira ntchito pamagetsi okwera, omwe amatentha mwachangu komanso amawongolera kugwiritsa ntchito mphamvu moyenera. Izi zikutanthauza kuti magalimoto amagetsi okhala ndi zotenthetsera za HV PTC amatha kutenthetsa chotenthetsera chawo mwachangu komanso osakhudza kwambiri kuchuluka kwa magalimoto omwe amayendetsa, zomwe zimapangitsa kuti ogula aziyendetsa bwino.

Kuphatikiza apo, ukadaulo wapamwamba womwe umagwiritsidwa ntchito muChotenthetsera cha HV PTCs imalola kuwongolera kutentha kolondola, kuonetsetsa kuti choziziritsira chimatenthedwa kufika kutentha koyenera kuti galimoto igwire bwino ntchito komanso kuti munthu akhale bwino. Izi sizimangowonjezera mphamvu ya makina otenthetsera a EV, komanso zimawonjezera luso la ogwiritsa ntchito onse, zomwe zimapangitsa kuti ma EV akhale njira yokongola kwambiri kwa ogula.

Kuyambitsa ma heater a HV PTC ndikofunikira kwambiri kwa opanga magalimoto amagetsi chifukwa kumapereka mwayi wowonjezera magwiridwe antchito ndi kukongola kwa magalimoto. Mwa kupereka kutentha koziziritsa kuzizira mwachangu komanso kogwira mtima, opanga ma EV amatha kupititsa patsogolo mpikisano wa zinthu zawo pamsika wa ma EV womwe ukuchulukirachulukira, zomwe zingakope makasitomala ambiri ndikupeza malo olimba mumakampani.

Opanga magalimoto amagetsi otsogola angapo ayamba kuphatikiza magalimoto amagetsichotenthetsera cha PTC champhamvu kwambiriKulowa m'magalimoto awo, pozindikira ubwino womwe ukadaulo uwu ungabweretse. Pakuchita izi, sikuti amangowonjezera magwiridwe antchito ndi magwiridwe antchito a magalimoto amagetsi komanso amawonetsa kudzipereka kwawo pakupanga zatsopano ndi kupita patsogolo kwa ukadaulo wamagalimoto amagetsi.

Pamene msika wamagalimoto amagetsi ukupitilira kukula ndikukula, chitukuko cha ukadaulo wapamwamba monga ma heater a PTC amphamvu kwambiri chidzakhala ndi gawo lofunikira pakukonza tsogolo la magalimoto amagetsi. Mwa kulola kutentha koziziritsa kuzizira mwachangu komanso moyenera, ukadaulo uwu uli ndi kuthekera kothana ndi mavuto ena akuluakulu omwe akukumana ndi kugwiritsa ntchito magalimoto amagetsi mosiyanasiyana, monga nkhawa ya malo osiyanasiyana komanso mavuto okhudzana ndi kugwiritsa ntchito mphamvu.

Kuphatikiza apo, kuyambitsidwa kwa ma heater a PTC amphamvu kwambiri ndi gawo lofunika kwambiri pakupitiliza kupanga ndi kukonza ukadaulo wamagalimoto amagetsi. Pamene opanga akuyesetsa kupanga magalimoto amagetsi kukhala opikisana komanso okoka kwa ogula, zatsopano mu makina otenthetsera ndi ozizira zitha kukhala ndi gawo lofunika kwambiri pakukwaniritsa zolinga izi.

Pomaliza, chitukuko ndi kukhazikitsaChotenthetsera choziziritsira cha EVikuyimira gawo lofunika kwambiri pakupitiliza kupanga magalimoto amagetsi. Mwa kupereka magwiridwe antchito abwino, magwiridwe antchito abwino komanso chidziwitso cha ogwiritsa ntchito, ukadaulowu uli ndi kuthekera koyendetsa kugwiritsa ntchito magalimoto amagetsi ambiri ndikufulumizitsa kusintha kupita ku njira yoyendetsera yokhazikika komanso yobiriwira.
