Mu iterambere rikomeye ku nganda zikoresha amashanyarazi (EV), hakozwe icyuma gishyushya gishyushya gikoresha amashanyarazi menshi (PTC) (coefficient temperature coefficient) gisezeranya kunoza cyane imikorere n'imikorere ya sisitemu zo gushyushya zikoresha amashanyarazi. Kizwi nka HV PTC heater, ubu buryo bugezweho buzahindura uburyo imodoka zikoresha amashanyarazi zishyushya icyuma gishyushya, bikazana inyungu nyinshi ku bakora amashanyarazi n'abaguzi.
Ibinyabiziga bisanzwe bikoresha amashanyarazi byishingikiriza ku byuma bishyushya bya PTC bisanzwe kugira ngo bishyushye icyuma gikonjesha kiri muri sisitemu. Ibi byuma bishyushya bikoresha resistor kugira ngo bikore ubushyuhe iyo amashanyarazi anyujijwemo, ariko bishyuha buhoro buhoro kandi akenshi ntibikora neza. Ibi bituma igihe kirekire cyo gushyushya gikoreshwa kandi ingufu zigakoreshwa ziyongera, bigira ingaruka mbi ku rwego rusange n'imikorere y'imodoka ikoresha amashanyarazi.
Ariko, icyuma gishya gishyushya PTC gifite umuvuduko mwinshi gifite inyungu nyinshi z'ingenzi ugereranyije n'icyuma gishyushya PTC gisanzwe. Icya mbere, gikoresha ingufu nyinshi, zishyushya vuba kandi zikongera imikorere myiza y'ingufu. Ibi bivuze ko imodoka zikoresha amashanyarazi zifite icyuma gishyushya HV PTC zishobora gushyushya icyuma gishyushya vuba kandi nta ngaruka nyinshi ku buryo zitwara, amaherezo bikanongerera abakiriya uburambe muri rusange bwo gutwara.
Byongeye kandi, ikoranabuhanga rigezweho rikoreshwa muriIgishyushya cya HV PTCs ituma habaho kugenzura ubushyuhe neza, bigatuma icyuma gikonjesha gishyuha kugeza ku bushyuhe bwiza kugira ngo imodoka ikore neza kandi ihumure. Ibi ntibinoza gusa imikorere ya sisitemu zo gushyushya za EV, ahubwo binanongera ubunararibonye bw'umukoresha muri rusange, bigatuma EV iba amahitamo meza ku bakoresha.
Gushyiramo amashanyarazi ya HV PTC ni ingenzi cyane ku bakora imodoka zikoresha amashanyarazi kuko bitanga amahirwe yo kongera imikorere n'ubwiza bw'imodoka. Mu gutanga ubushyuhe bwihuse kandi bunoze, abakora amashanyarazi bashobora kongera ubushobozi bwo guhangana n'ibicuruzwa byabo ku isoko ry'imodoka zikoresha amashanyarazi, bikaba byakurura abakiriya benshi no kugira intera ikomeye mu nganda.
Inganda nyinshi zikomeye zikora imodoka zikoresha amashanyarazi zatangiye kwihuzaicyuma gishyushya PTC gifite voltage nyinshis mu binyabiziga byabo, bazirikana inyungu zishobora kuboneka muri iri koranabuhanga. Muri urwo rwego, ntibanoza gusa imikorere n'imikorere myiza y'ibinyabiziga bikoresha amashanyarazi, ahubwo banagaragaza ubushake bwabo mu guhanga udushya no guteza imbere ikoranabuhanga ry'ibinyabiziga bikoresha amashanyarazi.
Uko isoko ry’ibinyabiziga bikoresha amashanyarazi rikomeza gukura no gutera imbere, iterambere ry’ikoranabuhanga rigezweho nka amashanyarazi ya PTC afite ingufu nyinshi rizagira uruhare runini mu gushyiraho ahazaza h’ibinyabiziga bikoresha amashanyarazi. Mu gutuma habaho ubushyuhe bwihuse kandi bunoze, ubu buhanga bufite ubushobozi bwo gukemura bimwe mu bibazo by’ingenzi bihura na byo mu gukoresha ibinyabiziga bikoresha amashanyarazi, nko guhangayika mu buryo butandukanye no gukoresha ingufu.
Byongeye kandi, gutangiza ibyuma bishyushya bya PTC bifite ingufu nyinshi bigaragaza intambwe ikomeye mu iterambere rikomeje no kunoza ikoranabuhanga ry’ibinyabiziga bikoresha amashanyarazi. Mu gihe abakora baharanira gutuma ibinyabiziga bikoresha amashanyarazi birushaho gupiganwa no gukurura abaguzi, udushya mu buryo bwo gushyushya no gukonjesha dushobora kugira uruhare runini mu kugera kuri izi ntego.
Amaherezo, iterambere n'ishyirwa mu bikorwa ryaIgishyushya gikonjesha cy'amashanyaraziikimenyetso cy'ingenzi mu iterambere rikomeje ry'imodoka zikoresha amashanyarazi. Mu gutanga umusaruro mwiza, imikorere myiza n'uburambe bw'abakoresha, ikoranabuhanga rifite ubushobozi bwo gutuma imodoka zikoresha amashanyarazi zikoreshwa cyane kandi rigatuma zihutishwa no kugera ku buryo burambye kandi bunoze bwo gutwara abantu.
