IP ratings,kanaIngress Dziviriro ratings, inoshanda sechiyero chekudzivirira kwechigadzirwa pakupinzwa kwezvinhu zvekunze, zvinosanganisira huruva, tsvina, uye mwando. Yakagadzirwa neInternational Electrotechnical Commission (IEC), iyi rating system yave chiyero chepasi rose chekuongorora kusimba uye kuvimbika kwemidziyo yemagetsi. Inosanganisira mbiri dzenhamba, iyo IP chiyero inopa ongororo yakazara yekugona kudzivirira kwemudziyo.
Nhamba yekutanga muyero yeIP inoreva mwero wedziviriro pazvinhu zvakasimba, seguruva nemarara. Dijiti rekutanga repamusoro rinoratidza kudzivirira kwakawedzera kubva kune aya ma particle. Kune rumwe rutivi, nhamba yechipiri inoreva kuramba kwemudziyo kune zvinwiwa, ine kukosha kwepamusoro kunoratidza chiyero chepamusoro chekudzivirira kubva mukunyorova.
Muchidimbu, iyo IP rating system inopa yakajeka uye yakamisikidzwa nzira yekutaurirana kusimba uye kuvimbika kwemidziyo yemagetsi, ichibvumira vatengi nenyanzvi dzeindasitiri kuita sarudzo dzine ruzivo zvichienderana nemamiriro ezvakatipoteredza umo mudziyo uchashandiswa. Nheyo yacho iri nyore: iyo yakakwirira iyo IP rating, iyo inonyanya kusimba chishandiso kune ekunze zvinhu, ichipa vashandisi chivimbo mukuita kwayo uye hupenyu hurefu.
(IP chiyero kubva kuIEC)
Kuve nechokwadi chekusimba kweElectric Vehicle (EV) yekuchaja zviteshi kwakakosha, ne IP ratings ichiita basa rakakosha mukuchengetedza izvi zvakakosha zvivakwa. Kukosha kwezviyero izvi zvinonyanya kutaurwa nekuda kwekuiswa kwekunze kwezviteshi zvekuchaja, zvichivaisa pachena kune zvisingatarisike zvechisikigo zvakaita semvura, sinou, uye kushata kwemamiriro ekunze. Kusavepo kwedziviriro yakakwana kubva mukunyorova hakungokanganisi kushanda kwechiteshi chekuchaja asiwo kunoisa njodzi dzakakomba dzekuchengetedza.
Funga nezvechiitiko apo mvura inopinda aImba EV yekuchaja chiteshi- chiitiko chinoratidzika sechisina mhosva chinogona kuva nemigumisiro yakaoma. Kupinda kwemvura kune mukana wekupinza zvikabudura zvemagetsi uye kumwe kusashanda zvakanaka, zvichizoguma nemamiriro ezvinhu ane njodzi semoto kana electrocution. Pamusoro pezvinonetsa zvekuchengetedza, iko kunyangira kwehunyoro kunosvika pakuora uye kuparara kwezvinhu zvakakosha mukati mechiteshi chekuchaja. Izvi hazvingokanganisa kushanda kwechiteshi ichi chete asi zvinosanganisirawo tarisiro yekugadzirisa kunodhura kana, kana zvakanyanyisa, kutsiva zvachose.
Mukutsvaga kwekufamba uye kutendeseka kwemagetsi kufamba, kugadzirisa kusagadzikana kweEV yekuchaja zviteshi kune zvakatipoteredza zvinhu zvakakosha. Tichiziva basa rakakosha rinoitwa neIP ratings mukudzikisa njodzi, kubatanidzwa kwematanho ekudzivirira epamusoro anova musimboti wekuona hupenyu hurefu uye kuchengetedzeka kweizvi zvakakosha zvekuchaja zvivakwa. Sezvo shanduko yepasi rose yakananga kumotokari dzemagetsi ichikwira, kusimba kwezviteshi zvekuchaja mukutarisana nemamiriro ekunze akasiyana-siyana kunobuda seyakakosha kutariswa kwekugashira kusina musono kweeco-hushamwari chekufambisa mhinduro.

Kusarudza EV yekuchaja zviteshi zvine yakakwira IP chiyero kwakakosha. Isu tinopa zano shoma IP54 yekushandisa kunze, kudzivirira kubva kuguruva nemvura. Mumamiriro ezvinhu akaoma sechando chakanyanya kana mhepo ine simba, sarudza IP65 kana IP67. Injet New Energy imba uye yekutengesaAC majaja(Swift/Sonic/The Cube) shandisa iyo yepamusoro IP65 rating iripo pamusika.IP65inopa kudzivirira kwakasimba kubva kuguruva, kuderedza zvimedu zvinopinda mumidziyo.
