Ushintsho olusheshayo oluya ekusebenziseni izimoto zikagesi lulethe ugcagca lwezinto ezintsha, izinguquko emithethweni, kanye nengxoxo yomphakathi mayelana nokuphepha. Njengoba izimoto ezisebenzisa ibhethri likagesi (EVs) ziba yinto ejwayelekile emigwaqweni emhlabeni wonke, kuvelile ukukhathazeka ngokuthi lezi zinjini ezithule, ezinamandla amakhulu zisebenzisana kanjani nabahamba ngezinyawo, abagibeli bamabhayisikili, nabanye abasebenzisi bomgwaqo abasengozini. Abanye abagxeki bathi ukuthula kwezimoto zikagesi lapho zihamba kancane kudala ingozi efihlekile, kanti abanye bakhathazeka ngobungozi buka-gesi obuhambisana nezinhlelo zikagesi eziphakeme kakhulu. Kodwa-ke, isifundo esisha esiphelele siyaphikisa lezi zinkolelo, sibonisa ukuthi izimoto zikagesi azibonakali zibucayi kubahamba ngezinyawo kunama-injini ezishisayo. Eqinisweni, lapho zihlelwe kahle ngezinhlelo zokuxwayisa ngezwi futhi zisekelwa ukuhlolwa okuqinile kokuphepha kukagesi, izimoto zikagesi zingaba ukukhetha okuphephile kuwo wonke umuntu. Lesi sihloko sihluza imiphumela yesifundo, siqhathanisa ukuphepha kwezimoto zikagesi nezimoto ezisebenzisa ugesi nezingawo, sihlola indima ye-Acoustic Vehicle Alert System (AVAS), futhi sixoxa ngemiphumela ebanzi yokuphepha kwezimoto zikagesi. Ukuqonda lezi zici ezihlukahlukene kubalulekile kubaphathi bezimoto, abahleli bedolobha, nabathengi abafuna ukwenza izinqumo ezinolwazi mayelana nezokuthutha ezisimeme ngenkathi bephambili ukuphepha komphakathi.

Ngaphandle kokuphepha okusheshayo kwezihambi, ukusetshenziswa kukagesi kwezokuthutha kuthinta nokuphepha kukagesi ekhaya, ukuhambisana kwendawo yokusebenza (njenge-NFPA 70E), kanye nesidingo sokuphathwa kahle kwezingozi zikagesi ezindaweni zokushaja. Njengoba izinhlangano ezifana ne-Lanxi Lifei Supply Chain Management Co., Ltd. (lifei) zinikeza izingxenye ezibalulekile zikagesi ezindlini nasezindaweni zokuhweba, ukuhlangana kokwamukelwa kwe-EV nokuphepha kukagesi kubaluleke kakhulu. Lesi sihloko sizohlinzeka ngokujula kwedatha, ukuchitha izinganekwane, futhi sinikeze ukuqonda okusebenzayo kumabhizinisi kanye nabantu ngabanye abafuna ukwamukela ukuhamba kukagesi ngaphandle kokudela ukuphepha. Ekugcineni, uzokuqonda ukuthi kungani igama elithi "safety electric" lingeyona nje isiqubulo sokumaketha kodwa iqiniso elingalinganiswa elisekelwa isayensi nobunjiniyela.

Ucwaningo olubalulekile olwashicilelwa ku-Journal of Transport & Health luhlaziye idatha yezingozi ezivela emazweni amaningi, luqhathanisa amazinga okwenzeka ukulimala kwezihambi ezimotweni ezisebenzisa ugesi (BEVs) nalezo ezisebenzisa injini yokushisa (ICEVs). Imiphumela ibimangalisa: ngemuva kokulawula izinto ezifana nosayizi wemoto, isivinini, kanye nendlela umshayeli aziphatha ngayo, i-BEVs ayihlotshaniswa nengozi enkulu yokulimala noma ukufa kwezihambi. Eqinisweni, ezindaweni eziningi zasemadolobheni, i-BEVs ibonise amazinga aphansi kancane ezingozi nezihambi, cishe ngenxa yokukwazi kwayo okungcono kakhulu ukuzulazula ngesivinini esiphansi kanye nezinhlelo zokubopha ezibuyisela amandla ezinganciphisa ibanga lokumisa. Lesi sitholakale sihlukana ngqo nendaba edumile ethi ama-EV athule ayisidina kubahamba ngezinyawo nabagijimayo. Kunalokho, idatha iphakamisa ukuthi iphrofayela yokuphepha kwe-EVs yesimanje ingalingana neyezimoto zakudala, inqobo nje uma izimoto zihlome ngezinhlelo zokuxwayisa ngezwi eziyisibopho futhi abashayeli beqeqeshwe ukuphatha izici ezihlukile zamandla ezinjini zikagesi.

Esinye isici esibalulekile salo sifundo kwakuwukunakwa kwaso ekunciphiseni ubungozi buka-gesi ekwakhiweni kwe-EV. Izimoto ze-BEV zesimanje zidlula ekuhlolweni okuningiliziwe kwezokuphepha kukagesi ukuze kuqinisekiswe ukuthi amabhethri aphezulu kagesi kanye ne-power electronics ahlukaniswe nomzimba wezimoto nokuthi abasindisi bangakwazi ukuvala uhlelo ngokuphepha uma kwenzeka ingozi. Lezi zivivinyo zihambisana namazinga omhlaba wonke njenge-ISO 6469 kanye ne-UN Regulation No. 100, ezihlanganisa yonke into kusukela ekumeleni ugesi kuya ekugwemeni ukushisa ngokweqile. Ezinkampanini eziqhubayo izimoto ze-EV, ukuqonda la mazinga kubalulekile ngoba futhi anikeza iziqondiso ezinhle kakhulu zokuphepha kukagesi ekhaya lapho kufakwa iziteshi zokushaja. Ngokuhlanganisa iziqondiso ze-NFPA 70E emisebenzini kagesi nokusebenzisa izinto eziqinisekisiwe ezivela kubahlinzeki njenge-lifei, izinhlangano zingakha uhlelo oluphelele lokuphepha kukagesi oluvikela abantu nempahla.

Izimoto ezihlangene (HEVs) zithatha indawo eyingqayizivele endaweni yokuphepha. Ucwaningo olufanayo lwembula ukuthi i-HEVs empeleni inezinga eliphezulu lokushayisana nabahamba ngezinyawo kune-BEVs noma i-ICEVs. Lokhu kuvezwa ngenxa yokuthi amaningi ama-hybrid asebenza ngemodi kagesi kuphela ngesivinini esiphansi kodwa angakwazi ukusebenzisa injini yokushisa ngokungazelelwe, okudala umsindo ongabikeleki namaphethini okusheshisa angadida abahamba ngezinyawo. Kodwa-ke, ubunzima ukulimala ezingozini ze-HEV-zabahamba ngezinyawo buvame ukuba buphansi, cishe ngenxa yokuthi imiklamo ye-hybrid ivame ukuhlanganisa izinto ezithambile ngaphambili kanye nokuphakama okuphansi kwe-hood, okunciphisa amandla okushayisana. Le paradox igqamisa isifundo esibalulekile: ukuphindaphinda kokushayisana kanye nobunzima ukulimala kufanele kuhlolwe ngokwehlukana lapho kuhlolwa ukuphepha kokusebenza kukagesi. Kubashayeli abacabanga nge-hybrid njengobuchwepheshe bokuguquguquka, kubalulekile ukukhetha amamodeli anezinhlelo ezithuthukisiwe zokuthola abahamba ngezinyawo kanye nokubopha ngokuzenzakalelayo okuphuthumayo.

Ngokombono wezingozi zikagesi, izimoto ezihlangene (hybrids) zethula ubunzima obengeziwe ngoba ziqukethe izinhlelo zikagesi eziphakeme kakhulu (high-voltage traction systems) kanye nezinhlelo zikagesi ezijwayelekile ezingu-12-volt, kanye nemishayo yamafutha nezingxenye zokukhipha umusi. Leli hlelo kabili lenza ukuthi ukuhlolwa nokugcinwa kahle kwezokuphepha kukagesi kube kubaluleke kakhulu. Ochwepheshe abasebenza ezimotweni ezihlangene (hybrids) kufanele babe ne-NFPA 70E‑certified futhi balandele izinqubo eziqinile zokukhiya/ukulebula (lockout/tagout) ukuze bagweme ukushaywa ugesi noma izingozi zokukhanya okukhulu (arc flash incidents). Izinkampani ezifana ne-lifei, ezinikeza iziphazamisi zesifunda (circuit breakers), izishintshi (switches), namakhebula (cables) asezingeni eliphezulu ezindaweni zokuhlala nezamabhizinisi, zidlala indima ebalulekile ekuqinisekiseni ukuthi ingqalasizinda yokushaja nokugcinwa kwezimoto ezihlangene (hybrids) nezimoto zikagesi (EVs) ihlangabezana namazinga aphezulu kakhulu okuphepha. Noma ngabe ufaka isiteshi sokushaja ekhaya noma uthuthukisa igalaji lebhizinisi, ukukhetha izingxenye ezinamabanga okuphakama kwezingozi zikagesi okufakazelwe kuyingxenye eyisisekelo yanoma yisiphi isistimu yokuphepha kukagesi.

Uhlelo Lokuxwayisa Ngezimoto Ezizwakala Ngomsindo (AVAS) ubuchwepheshe obuyalelwe imithetho ezindaweni eziningi, okubalwa i-European Union ne-United States, ukubhekana nokukhathazeka ngezimoto ezithule kakhulu. I-AVAS yenza imisindo eyenziwe lapho imoto kagesi noma i-hybrid ihamba ngesivinini esiphansi (ngokuvamile ngaphansi kuka-30 km/h), ixwayisa abahamba ngezinyawo nabagibeli bamabhayisikili ukuthi imoto ikhona. Ucwaningo luthole ukuthi izimoto ezine-AVAS zibone ukuncipha okufika ku-40% kwezingozi zabahamba ngezinyawo ngesivinini esiphansi uma ziqhathaniswa nezimoto ezingenalo uhlelo. Lokhu kuyisibonelo esinamandla sokusebenza kwezinyathelo zokuphepha ezilula, eziklanywe kahle. Kubakhiqizi nabaphathi bezimoto, ukuqinisekisa ukuthi i-AVAS ilungiswe kahle futhi inakekelwa kuyindlela eshibhile, enomthelela omkhulu yokuthuthukisa ukuphepha kwezimoto zikagesi. Okubalulekile, imisindo ye-AVAS yakhelwe ukuthi ibe yiqondile futhi incike kusivinini, ngakho-ke inikeza ulwazi oluwusizo ngaphandle kokwengeza ekungcoleni komsindo emadolobheni.

Ukuhlanganisa i-AVAS nezinhlelo ezibanzi zokuphepha kudinga ukunakwa ekunqandeni kwezingozi zikagesi. Iyunithi ye-AVAS ngokwayo iyisici sikagesi okumelwe inikwe amandla ngokuthembekile futhi ivikelwe ekushayweni okufushane nasezimo zokudlula kukagesi. Kulapho izimiso zokuphepha kukagesi zasekhaya zisebenza khona: njengoba isiphazamisi somjikelezo wasekhaya sivikela izintambo ekulayisheni ngokweqile, umjikelezo we-AVAS ku-EV kufanele ube ne-fuse futhi ubantshontshwe ukuze kuvinjelwe ukwehluleka okungase kuthulise isexwayiso. Ezinkampanini ezinikeza izinto zikagesi—njenge-lifei, enikeza imikhiqizo ye-DELIXI Electric ehlukahlukene okubalwa kuzo iziphazamisi zomjikelezo nama-relay—ukuqinisekisa ukuthi izinto zikagesi zokuphepha zihlangabezana namazinga e-automotive-grade kubalulekile. Ngokuthola izinto eziqinisekisiwe nokulandela izinqubo eziqinile zokuhlola ukuphepha kukagesi, abakhiqizi bangakha izinhlelo ze-AVAS ezisebenza ngokuthembekile impilo yonke yemoto, ngaleyo ndlela banciphise ingozi yokushayisana nabahamba ngezinyawo.

Ubufakazi obuqoqiwe buvela ocwaningweni, obuhlanganiswe nokusebenza okufakazelwe kwe-AVAS kanye nobunjiniyela besimanje bezokuphepha, benza icala eliqinisekisa ukuthi izimoto ezisebenzisa ugesi zebhethri ziyisinqumo esiphephile kubahamba ngezinyawo nabashayeli ngokufanayo. Ngokombono wokuphepha kukagesi, izimoto zikagesi zinikeza izinzuzo eziningana ezibalulekile: azinawo uphethiloli owuketshezi ovutha kalula, zinezikhungo eziphansi kakhulu zamandla (kunciphisa ubungozi bokugingqika), futhi amaphakethe azo amabhethri afakwe ezakhiweni eziqinile, ezivikelwe ezingozini. Ngaphezu kwalokho, i-drivetrain kagesi ivumela ukulawulwa okunembayo kwe-torque, okungathuthukisa ukulawulwa kokuzinza kanye nezinhlelo zokudonsa. Ezinkampanini ezibeka phambili ukuphepha ezimoto zazo, ukushintshela ezimotweni zikagesi—kanye nokwenza ukuqeqeshwa okufanele kanye nengqalasizinda—kunganciphisa izinga eliphelele lezehlakalo kanye nesibopho. Igama elihlobene elithi “safety electric” ngakho-ke lihlanganisa hhayi imoto kuphela kodwa futhi lonke uhlelo lweziteshi zokushaja, izindlela zokugcinwa, kanye nokuthobela izindinganiso ezifana ne-NFPA 70E.

Ezinkampanini ezifana ne-lifei, ezingochwepheshe ekuhlinzekeni izinto zikagesi ezisetshenziswa emakhaya, ezamabhizinisi, nezamathuluzi, ukwanda kwezimoto zikagesi (EVs) kunikeza ithuba lokukhuthaza ukuphepha okuphelele kukagesi. Lapho ikhasimende lithenga i-EV, ngokuvamile lidinga ukufaka isiteshi sokushaja ekhaya, esidinga ukuhlolwa kokuphepha kukagesi ekhaya, ukufakwa komhlaba okufanele, nokusetshenziswa kwama-circuit breaker afanelekayo. I-lifei inganikeza izingxenye ezidingekayo—kusukela ezintanjeni nezishintshi kuya kumadivayisi athuthukile okulinganisa nokuvikela—ukuqinisekisa ukuthi ukufakwa kokushaja kuhlangabezana nazo zonke izidingo zamakhodi. Ngaphezu kwalokho, ukubandakanyeka kwe-lifei emkhakheni omusha wamandla kubavumela ukuthi banikeze izixazululo ezihlanganisiwe ezihlanganisa ama-solar inverter, amabhethri, kanye nama-EV charger, konke okuklanywe ngokuhlolwa okuqinile kokuphepha kukagesi. Ngokukhetha i-lifei njengomlingani, amabhizinisi kanye nabangumnikazi bamakhaya bangakha ingqalasizinda kagesi ephephile ngempela esekela ezokuthutha ezisimeme ngaphandle kokudela ukuvikelwa ezintweni eziyingozi zikagesi.

Idatha icacile: izimoto ezisebenzisa amabhethri kagesi azinobungozi ezihambini kunama-car ajwayelekile, futhi uma zihlinzekwa nge-AVAS futhi zisekelwa amazinga aphezulu okuphepha, zingaba nezingozi kakhulu. Iziphetho zocwaningo ziqeda inkolelo-mbumbulu "yokubulala okuthule" futhi zigcizelela ukubaluleka kokwenziwa kwezinqubomgomo okusekelwe ebufakazini ekuvikelekeni kwezokuthutha. Ezinkampanini ezifuna ukunciphisa ukukhishwa kwazo kwe-carbon nokuthuthukisa iphrofayela yazo yokuphepha kagesi, ukuguqukela kuma-EV kuyisinyathelo esinengqondo nesinomthwalo wemfanelo. Kodwa-ke, ukuphepha akugcini emotweni uqobo. Kufinyelela kwingqalasizinda yokushaja, izingxenye zikagesi ezisetshenzisiwe, nokuqeqeshwa okunikezwa ochwepheshe nabashayeli. Ukuthobela imihlahlandlela ye-NFPA 70E, ukwenza ukuhlolwa okuphelele kokuphepha kukagesi, nokubhekana nezingqinamba zokuphepha kukagesi ekhaya konke kuyingxenye ebalulekile yendlela ephelele.

KwaLifei (Lanxi Lifei Supply Chain Management Co., Ltd.), sizibophezele ekusekeleni lokhu kushintsha ngokunikeza imikhiqizo kagesi esezingeni eliphezulu ehlangabezana nezindinganiso eziqinile zokuphepha. Noma ngabe udinga izingxenye zesishaja se-EV sasekhaya, isiteshi sokushaja sezohwebo, noma uhlelo oluphelele lwe-solar-plus-storage, ikhathalogi yethu—ebonisa imikhiqizo ye-DELIXI Electric, izixazululo zamandla amasha, nokunye—inikeza ukwethembeka okudingayo. Vakashela i-Ikhayaikhasi ukuze ufunde kabanzi ngenkampani yethu, noma hlola i-Amandla amasha ikhasi ukuze uthole okwakamuva kubuchwepheshe be-solar ne-EV charging. Ukuze uthole izibuyekezo zemboni nezincomo ezinhle kakhulu ekuvikelekeni kukagesi, hlola i-Izindaba ikhasi. Futhi uma usulungele ukuthenga, i-DELIXI Electric ikhasi linikeza uhla olubanzi lwezishintshi, iziphazamisi zesekethe, nezintambo eziklanyelwe izicelo zikagesi ezivikelekile. Khetha ugesi, khetha ukuphepha, futhi ukhethe ikusasa elisimeme nge-lifei.

Ngokwamukela lonke uhla lwezindlela zokuphepha zikagesi—kusukela ekwakhiweni kwezimoto kuya ekukhetheni izingxenye nokufakwa—singakha uhlelo lwezokuthutha oluvikela abahamba ngezinyawo, abashayeli, nabasebenzi ngokufanayo. Ikusasa liyigesi, futhi liphephile. Ake sihambe phambili ndawonye.
