Ngokuhamba kwesikhathi, izimoto ezintsha zamandla, ikakhulukazi izimoto ezisebenza ngogesi, zizoqhubeka nokugcina umfutho wazo wokukhula emhlabeni wonke, zinezidingo eziqinile zokukhipha umoya, ubuchwepheshe namanani ebhethri athuthukisiwe, ukuthuthukiswa okuqhubekayo kwengqalasizinda, kanye nokwamukelwa kwabathengi kwezimoto zikagesi. mude futhi mude.

Ingxenye ebaluleke kakhulu emotweni kagesi ibhethri. Ngamabhethri, isikhathi asiwona ummese, kodwa izinga lokushisa liwummese. Noma ngabe buhle kangakanani ubuchwepheshe bebhethri, amazinga okushisa aphezulu ayinkinga. Ngakho-ke, isistimu yokulawula ukushisa kwebhethri yaba khona.

Mayelana nesilulumagama esifana ne-ternary lithium kanye ne-ternary electric system, sesixoxile kakade ngekilasi lokufunda nokubhala ngaphambili, futhi namuhla sizodonsa uhlelo lokulawula ukushisa kwebhethri yezimoto zikagesi. Kuze kube manje, sixoxisane noMnu. Lars Kostede, umholi wephrojekthi we-HELLA China ejensi yokuqalisa, onguchwepheshe kulo mkhakha.

Iyini isistimu yokulawula ukushisa?

Ungakhohliswa yileli gama, lifana nephakeji yocingo oluphathwayo oseceleni komgwaqo, noma, ukukubeka kancane, “polymer finish.” “Isistimu yokuphatha okushisayo” ifana negama elihlanganisa konke.

Amasistimu ahlukene okuphatha okushisayo aqondise ezindaweni ezahlukene, njengethangi lamanzi lenjini, futhi isifudumezi-moya esisemotweni siyisici esikhulu ekunqumeni ukunethezeka kokugibela-kodwa akunjalo. Njalo uma kumiswa i-air conditioner yemoto, kungakhathaliseki ukuthi amandla okuhlunga u-chassis aqine kangakanani, yinhle kangakanani i-NVH? IRolls-Royce engenawo ama-air conditioner ayilungile njengeChery—ikakhulukazi ngalesi sikhathi sonyaka, ama-air conditioner abalulekile empilweni yabanikazi bezimoto. Okubalulekile.

Isistimu yokulawula ukushisa kwebhethri yemoto kagesi ikhuluma ngaleli phuzu.

Kungani amabhethri edinga isistimu yokulawula ukushisa?

Uma kuqhathaniswa nezimoto zikaphethiloli, ingozi yokuphepha “eyingqayizivele” yezimoto zikagesi ilele ekulawuleni okushisayo kwebhethri lamandla. Ngemuva kokuvela kokushisa okushisayo, ukusabalalisa kweketango okufana nokusabela kwe-thermonuclear kwenzeka.

Thatha ibhethri le-lithium elidumile le-18650 njengesibonelo. Amaseli amaningi ebhethri akha iphakethe lebhethri. Uma ukushisa kweseli yebhethri eyodwa kungalawuleki, ukushisa kuzodluliselwa endaweni ezungezile, bese amaseli ebhethri azungezile azoba nokusabela kweketango ngokulandelana okufana nomlilo. Phakathi nale nqubo, izihloko eziningi zocwaningo zizoqalwa, okuhlanganisa amazinga okushisa aphakathi nendawo, ukukhiqizwa kokushisa kwamakhemikhali nogesi, ukudluliswa kokushisa kanye nokuhanjiswa.

Indlela elula nephumelela kakhulu yokulawula iketango elinjalo le-thermal runaway iwukwengeza isendlalelo sokuhlukanisa phakathi kwamayunithi ebhethri lamandla-manje izimoto eziningi zikaphethiloli ziyakunaka, futhi indilinga yongqimba olufakwayo lubekwe ngaphandle kwebhethri.

Nakuba ungqimba olufakwa ngaphakathi luwuhlobo olulula lwesistimu yokulawula ukushisa kwebhethri, luphinde lube yilo oluhlupha kakhulu. Ngakolunye uhlangothi, ukushuba kwesendlalelo sokufakwa kuzothinta ngqo umthamo ophelele wephakethe lebhethri; ngakolunye uhlangothi, isendlalelo se-insulation “iwuhlelo lokulawula ukushisa okwenziwayo” olubambezela iphakethe lebhethri lapho lidinga ukushisisa noma ukupholiswa.

Izinga lokushisa elingcono kakhulu elisebenzayo lebhethri ye-lithium yendabuko ngu-0 ℃ ~ 40 ℃. Izinga lokushisa elidlulele lizonciphisa umthamo wokugcina webhethri nempilo yomjikelezo webhethri. Eqinisweni, izinga lokushisa eliphansi ehlobo lingase lidlule ku-40 ° C, futhi wonke umuntu uyazi ukuthi izinga lokushisa lemoto evaliwe lingadlula i-60 ° C ehlobo. Ngokufanayo, ingaphakathi lephakethe lebhethri liphinde libe yindawo evalekile futhi kuzoshisa kakhulu… Ezimotweni ezisebenza ngogesi, uhlelo oluphelele lokulawula ukushisa kwebhethri lubaluleke kakhulu.

Uhlobo oluthile lwezimoto zikagesi ezithengiswa ngezinga elikhulu eNyakatho Melika ngo-2011, ngenxa yohlelo lwayo olulula lokulawula ukushisa kwebhethri, umthamo webhethri wawola kakhulu ngemva kweminyaka engu-5, okuholele ekutheni abanikazi bezimoto baseNyakatho Melika bakhokhe u-$5,000 ukuze bashintshe ibhethri. .

Futhi uma izinga lokushisa lingaphansi kuka-0 ° C, amandla okukhipha amabhethri e-lithium ajwayelekile azoncishiswa-owaziwa nangokuthi “ukugijima”. Ngaphezu kwalokho, ukushisa okuphansi, kubi nakakhulu umsebenzi we-ionization webhethri, okuzoholela ekunciphiseni kokushaja kahle, okungukuthi, “kunzima ukushaja kanye nomthamo ophansi”. Isistimu yokulawula ukushisa okushisayo kwebhethri enhle izoshisisa iphakethe lebhethri ngaphambi kokushaja ngezinga lokushisa eliphansi, futhi inomsebenzi wokufaka amandla aphansi lapho ugesi uxhunyiwe.

Eqinisweni, ezinye izinkampani zenze amabhethri e-lithium angamazinga okushisa aphansi afanele ukushisa okweqile kwemvelo. Isibonelo, ibhethri ye-lithium enezinga lokushisa eliphansi elakhelwe indawo epholile ingafinyelela ukushaja okusheshayo ku-0.2C ku -40°C kanye nomthamo wokushajwa ongekho ngaphansi kuka-80%. Ezinye zisebenza kahle ebangeni lokushisa elingu-50°C kuya ku-70°C futhi azidingi noma yiluphi usizo oluvela ohlelweni lokulawula ukushisa.

Lawa mabhethri e-lithium anzima ukuhlangabezana nezidingo zezinkampani zezimoto ngokulingana kwamandla kanye nezindleko, ngakho-ke ezinkampanini zezimoto, izinhlelo zokuphatha ukushisa kwebhethri ziseyisixazululo sezomnotho sokuqinisekisa impilo yebhethri nezimo zokusebenza.

Isebenza kanjani isistimu yokulawula ukushisa kwebhethri?

Umgomo wokusebenza wesistimu yokulawula ukushisa kwebhethri ufana ne-air conditioner yasendlini. Kalula nje, iyunithi yokulinganisa nokulawula inesibopho sokuqapha izinga lokushisa, futhi ingxenye yokulawula izinga lokushisa ishayela indawo yokudlulisa ukushisa ukuze iqedele ukulawulwa kokushisa kokugcina. Kodwa-ke, ukunemba kokulawula izinga lokushisa kwesistimu yokulawula ukushisa kwebhethri kuphakeme kakhulu kunaleyo yezifudumezi-moya zasendlini, futhi ingakwazi nokuqapha izinga lokushisa lebhethri elilodwa ephaketheni lebhethri.

Imidiya evamile yokuqhuba ukushisa ohlelweni lokulawula ukushisa kwebhethri izinto zokushintsha umoya, uketshezi kanye nesigaba. Ngenxa yokusebenza kahle nezinto zezindleko, iningi lamasistimu amanje okulawula ukushisa kwebhethri asebenzisa uketshezi njengendawo yokudlulisa ukushisa. Iphampu iyingxenye esemqoka yalolu hlelo lokulawula ukushisa kwebhethri.

Njengamanje, i-HELLA inikeza izingxenye eziningi eziyinhloko zesistimu yokulawula ukushisa kwebhethri yezimoto ezintsha zamandla, ezimele kakhulu i-electronic circulating water pump MPx, engakwazi ukulawula ngokunembile ukucindezela nokugeleza kwe-Themperature yokusebenza igcinwa endaweni ekahle. izinga lokufeza ukuqina kwesistimu yebhethri.

Ngaphezu kwalokho, isistimu yokulawula ukushisa kwebhethri ye-HELLA iphinde inikeze isisombululo sohlelo embonini yezimoto, hhayi nje isisombululo somkhiqizo, ikakhulukazi e-China, esibaluleke kakhulu…

Ngakho-ke, siyini isisombululo sesistimu, futhi yisiphi isisombululo esilula?

Thenga ikhompuyutha, isibonelo, utshela umthengisi ukusebenza, ukusetshenziswa, kanye nenani elithengekayo, umthengisi ukusiza ukuthi ukhethe imikhiqizo ethile futhi akutshele inqubomgomo yewaranti, akuthandele, ukhokhe, futhi wazise umdayisi ukuthi ufuna ukufaka noma iyiphi inguqulo. yesistimu yokusebenza , Ngosuku olulandelayo kukhompuyutha, ngemva kokusayinela okuthile, ikhompuyutha iphahlazeka ngokuqondile kumthengisi-lokhu kubizwa ngokuthi isisombululo sesistimu.

Isixazululo kuphela ukuthenga igobolondo lakho, i-CPU, i-fan, inkumbulo, i-hard drive, ikhadi lezithombe emakethe, bese uzenzela wena. Le nqubo ayikwazi ukuxazululwa phakathi kwezinsuku ezimbili. Futhi ikhompuyutha ehlanganisiwe ayinayo iwaranti. Uma umshini uhluleka, udinga ukuya ezingxenyeni zokunakekelwa ngamunye ngamunye, futhi uxhumane nabahlinzeki bezingxenye ezifanele ngemuva kokuthola izingxenye ezinephutha. Ngaphezu kwalokho, uma i-accessory ye-third party ilimele ngenxa yokungasebenzi kahle kwe-accessory, isibonelo, i-CPU iyasha ngenxa yenkinga yabalandeli, kungcono ukukhokha izindleko ze-fan entsha ngumphakeli wabalandeli, futhi ukulahlekelwa kwe-CPU ngeke kunxeshezelwe…

Lona umehluko phakathi kwesisombululo sesistimu nesixazululo esisodwa.
