Kutulutsidwa kwa Ma Heater Atsopano a PTC ndi HV a Magalimoto Amagetsi

Pamene magalimoto amagetsi akupitilira kutchuka, ukadaulo wotenthetsera ukukulirakulira. Chimodzi mwa zinthu zatsopano zomwe zachitika posachedwapa m'munda uno ndi kuyambitsa ma heater a PTC (positive temperature coefficient) ndi HV (high voltage) a magalimoto amagetsi.

Chotenthetsera cha PTC, chomwe chimadziwikanso kutiChotenthetsera choziziritsira cha PTC, ndi chinthu chotenthetsera chomwe chimagwiritsa ntchito chiŵerengero chabwino cha kutentha kuti chiwongolere kutentha komwe kumatulutsa. Izi zikutanthauza kuti kutentha kwa chotenthetseracho kukakwera, kukana kwake kumawonjezeka, zomwe zimapangitsa kuti kutentha komwe kumapangidwira kuyende bwino. Izi zimapangitsa kuti chotenthetsera cha PTC chikhale chogwira ntchito bwino komanso chotsika mtengo chifukwa sichimafuna njira yowongolera yapadera kuti chisunge kutentha komwe kukufunika.

Koma ma heater a high voltage coolant amapangidwira kuti azigwira ntchito ndi makina amphamvu kwambiri m'magalimoto amagetsi. Ma heater amenewa amapangidwira kuti azigwira ntchito pamagetsi kuyambira 400V mpaka 900V, zomwe zimapangitsa kuti azigwirizana ndi ma powertrain amphamvu kwambiri omwe amagwiritsidwa ntchito m'magalimoto ambiri amagetsi amakono.

Kuphatikiza kwa matekinoloje awiriwa, chotenthetsera cha PTC ndichotenthetsera choziziritsira champhamvu kwambiri, ikuyimira kupita patsogolo kwakukulu kwa makina otenthetsera magalimoto amagetsi. Mwa kugwiritsa ntchito luso la PTC heaters lochita bwino komanso lodzilamulira, komanso kugwirizanitsa makina amphamvu kwambiri ndi ma HV coolant heaters, opanga magalimoto amagetsi tsopano atha kupereka njira yotenthetsera yogwira mtima komanso yodalirika yamagalimoto awo.

Chimodzi mwa ubwino waukulu wa matekinoloje atsopano otenthetsera ndi kuthekera kwawo kokweza mphamvu zonse zamagalimoto amagetsi. Makina otenthetsera achikhalidwe, monga ma heater oletsa kupondereza, amatha kugwiritsa ntchito mphamvu zambiri, zomwe zimapangitsa kuti nthawi yoyendetsera ikhale yochepa komanso kuti batire ikhale yochepa. Mosiyana ndi zimenezi, ma heater otenthetsera a PTC ndi HV apangidwa kuti azigwira ntchito bwino, kugwiritsa ntchito mphamvu zochepa komanso kuchepetsa kuwononga magalimoto.

Kuphatikiza apo, matekinoloje atsopano otenthetsera amathanso kubweretsa mwayi woyendetsa bwino komanso wosavuta kwa eni magalimoto amagetsi. Ngakhale nyengo yozizira, ma heater a PTC ndi HV coolant amatenthetsa mkati mwa galimoto mwachangu komanso moyenera, kuonetsetsa kuti okweramo amakhala omasuka komanso otetezeka akakhala pamsewu.

Kuphatikiza apo, kuyambika kwa ukadaulo wamakono wotenthetsera kutentha uku kukuwonetsa kudzipereka kosalekeza kwa wopanga magalimoto amagetsi pakupititsa patsogolo luso latsopano ndikupereka zinthu zabwino kwa ogula.

Opanga magalimoto amagetsi aphatikiza ma heater a PTC ndi HV mu mitundu yawo yaposachedwa, ndipo mayankho ochokera kwa ogula akhala abwino kwambiri. Eni magalimoto amagetsi omwe ali ndi ukadaulo watsopano wotenthetsera akuti kutentha kwawonjezeka, kugwiritsa ntchito bwino mphamvu komanso kukhutira kwakukulu ndi magalimoto awo.

Poyang'ana zamtsogolo, n'zoonekeratu kuti PTC ndiChotenthetsera choziziritsira cha HVs ipitiliza kugwira ntchito yofunika kwambiri pakupitiliza kupanga makina otenthetsera magalimoto amagetsi. Pamene kufunikira kwa magalimoto amagetsi kukupitilira kukula, kufunikiranso kwa njira zotenthetsera zapamwamba zomwe zingapereke magwiridwe antchito komanso magwiridwe antchito kukukulirakulira.

Mwachidule, kuyambitsidwa kwa ma heater a PTC ndi HV coolant kukuyimira kupita patsogolo kwakukulu muukadaulo wamagetsi wotenthetsera magalimoto. Mayankho atsopano otenthetsera awa amathandizira kugwiritsa ntchito mphamvu moyenera, amawonjezera chitonthozo ndipo amagwirizana ndi ma powertrain amphamvu kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri kwa mbadwo wotsatira wamagalimoto amagetsi. Ndi maubwino awo otsimikizika komanso kulandiridwa bwino ndi ogula, ndi nkhani ya nthawi yokha kuti ma heater a PTC ndi HV coolant akhale mawonekedwe wamba m'magalimoto amagetsi padziko lonse lapansi.
