Mazhinji emagetsi emutoro wedunhu ane mutoro kabati, yakakura, inorema, inodhura, isingaite yekuisa uye zvichingodaro.EAK yepamusoro yemvura-yakatonhodzwa mutoro resistor kuti ikubatsire kugadzirisa simba rakakura, diki saizi, zvakachipa uye zvimwe zvakawanda zvakanaka.
Pamusoro pezvo, mumotokari dzese dzemagetsi uye dzemasanganiswa, kudzoreredza braking inzira inoshanda kwazvo yekudzoreredza simba nekuchaja bhatiri, asi dzimwe nguva inowana simba rakawanda kupfuura rinogona kubata bhatiri.Izvi zvinonyanya kuitika kumotokari hombe dzakaita semarori, mabhazi nemichina yekubuda mumigwagwa, Motokari idzi dzinotanga kudzika kwadzo kudzika nekukasika kana mabhatiri azara.Panzvimbo yekutumira yakawandisa ikozvino kune bhatiri, mhinduro ndeyekutumira kune bhureki resistor kana seti yemabhureki resistors anoshandisa kushorwa kushandura simba remagetsi mukupisa, uye kudzinga kupisa mukati memhepo yakapoteredza.Chinangwa chikuru chegadziriro ndeyekupisa. kuchengetedza mabhureki mhedzisiro paunenge uchidzivirira bhatiri kubva pakuwedzeredza panguva yekudzorerazve mabhureki, uye kudzoreredza simba kunokurudzira kunobatsira. "Kana chirongwa ichi chaitwa, kune nzira mbiri dzekushandisa kupisa," EAK inodaro.“Chimwe ndechekupisa bhatiri.Munguva yechando, bhatiri rinogona kutonhora zvekurikuvadza, asi iyo system inogona kudzivirira izvo kuti zvisaitike.Unogona kuishandisawo kudziyisa kabhini.”
Mumakore 15-20, pazvinogoneka, braking ichave yekuvandudza, kwete mechanic: izvi zvinogadzira mukana wekuchengetedza uye kushandisazve regenerative braking simba, pane kungoibvisa semarara kupisa.Simba racho rinogona kuchengetwa mubhatiri remotokari kana mune imwe nzira yekubatsira, senge flywheel kana supercapacitor.
Mumotokari dzemagetsi, kugona kweDBR kutora uye kutungamira simba kunobatsira nekugadzirisa mabhureki.Regenerative braking inoshandisa yakawandisa kinetic simba kuchaja bhatiri remota yemagetsi.
Inoita izvi nekuti mamotor ari mumotokari yemagetsi anogona kumhanya munzira mbiri: imwe inoshandisa magetsi kutyaira mavhiri uye kufambisa mota, uye imwe inoshandisa yakawandisa kinetic simba kuchaja bhatiri.Sezvo mutyairi anosimudza tsoka yake kubva pachitsiko chegasi uye anotsikirira bhureki, motokari inoramba kufamba kwemotokari, “Kuchinja nzira,” uye inotanga kupinzazve simba mubhatiri. Naizvozvo, mabhureki anovandudza simba anoshandisa mota dzemagetsi semajenareta, anochinja. yakarasa kinetic simba musimba rakachengetwa mubhatiri.
Paavhareji, regenerative braking iri pakati pe60% ne70% inoshanda, zvichireva kuti zvingangoita zviviri muzvitatu zvesimba rekinetic rakarasika panguva yekubhureki rinogona kuchengetwa uye kuchengetwa mumabhatiri eEV kuti riwedzere kukurumidza, izvi zvinovandudza simba remotokari uye zvinowedzera hupenyu hwebhatiri. .
Zvisinei, regenerative braking haigoni kushanda yoga.DBR inodiwa kuita kuti nzira iyi ive yakachengeteka uye inoshanda.Kana bhatiri yemotokari inenge yatozara kana hurongwa huchikundikana, simba rakawandisa harina nzvimbo yekuparara, izvo zvingaita kuti iyo yose braking system ikundike.Naizvozvo, DBR yakaiswa kuti iparadze iyi yakawandisa simba, iyo isingakodzeri regenerative braking, uye yakachengeteka kuibvisa sekupisa.
Mumvura-yakatonhorera resistors, kupisa uku kunopisa mvura, iyo inogona kushandiswa kune imwe nzvimbo mumotokari kupisa cab yemotokari kana kuti preheat bhatiri pachayo, sezvo kushanda kwebheteri kwakabatana zvakananga nekushanda kwayo kwekushanda.
Mutoro Unorema
DBR haina kukosha chete mune yakajairika EV braking system.Kana zvasvika kune mabhureki masisitimu emagetsi anorema-duty marori (HGV) , kushandiswa kwavo kunowedzera imwe layer.
Marori anorema mabhureki akasiyana nemota nekuti haatsamiri zvachose pakumhanya mabhureki kuti anonoke.Pane kudaro, vanoshandisa mabhureki ebetsero kana kuti endurance ayo anonotsa motokari pasi pamwe chete nemabhureki emumugwagwa.
Haakurumidzi kupisa panguva yekudonha kwenguva refu uye anoderedza njodzi yekuwora kwemabhureki kana kutadza kumira kwemabhureki emumugwagwa.
Mumarori anorema emagetsi, mabhureki anodzoreredza, achideredza kusakara mumigwagwa mabhureki uye kuwedzera hupenyu hwebhatiri uye huwandu.
Nekudaro, izvi zvinogona kuve nengozi kana sisitimu ikatadza kana bhatiri paki isina kubhadhariswa zvizere.Shandisa DBR kurasa simba rakawandisa nenzira yekupisa kuti uvandudze kuchengetedzeka kweiyo braking system.
Remangwana rehydrogen
Nekudaro, DBR haingoite basa mukubhureki.Tinofanirawo kufunga kuti vanogona sei kuva nemigumisiro yakanaka pamusika unokura wehydrogen fuel cell electric vehicles (FCEV) .Kunyange zvazvo FCEV inogona kunge isingakwanisi kupararira kwakapararira, teknolojia iripo, uye zvechokwadi ine tarisiro yenguva refu.
Iyo FCEV inofambiswa neProton exchange membrane fuel cell.FCEV inobatanidza mafuta ehydrogen nemhepo uye inoipomba musero remafuta kuti ichinje haidhirojeni kuita magetsi.Kana iri mukati mefuel cell, inokonzeresa kuita kemikari kunoita kuti paburitswe maerekitironi kubva muhydrogen.Maerekitironi aya anobva agadzira magetsi, anochengetwa mumabhatiri madiki anoshandiswa kugadzira magetsi.
Kana iyo haidhirojeni inoshandiswa kuvaisa simba ichigadzirwa kubva kumagetsi kubva kune inodzokororwa masosi, mhedzisiro ndeye yakakwana-isina kabhoni yekutakura system.
Izvo chete zvekupedzisira zvigadzirwa zvemafuta cell reactions magetsi, mvura uye kupisa, uye iyo chete inobuda imhute yemvura nemhepo, zvichiita kuti zvienderane zvakanyanya nekutangwa kwemotokari dzemagetsi.Zvisinei, vane zvimwe zvipingamupinyi zvekushanda.
Masero emafuta haakwanise kushanda pasi pemitoro inorema kwenguva yakareba, izvo zvinogona kukonzera matambudziko kana ichikurumidza kana kuderera nekukurumidza.
Tsvagiridzo yebasa remafuta cell inoratidza kuti kana sero remafuta richitanga kukurumidza, simba rekubuda kwefuel cell rinowedzera zvishoma nezvishoma kusvika padanho rakati, asi rinobva ratanga kutenderera nekuderera, kunyangwe kumhanya kunoramba kwakafanana.Iri simba risingavimbiki rinobuda rinopa dambudziko kune vanogadzira mota.
Mhinduro ndeyekuisa masero emafuta kuti asangane nepamusoro pesimba zvinodiwa kupfuura zvinodiwa.Semuenzaniso, kana FCEV ichida 100 kilowatts (kW) yemagetsi, kuisa 120 kW fuel cell inoita kuti inosvika zana resimba rinodiwa rinogara riripo, kunyangwe simba remafuta sero rinodzikira.
Kusarudza mhinduro iyi kunoda kuti DBR ibvise simba rakawandisa nekuita "Load group" mabasa kana isingadiwi.
Nekutora simba rakawandisa, DBR inogona kuchengetedza masisitimu emagetsi eFCEV uye kuvagonesa kupindura zvakanaka kune yakakwira simba zvinodiwa uye kumhanyisa uye kudzikisira nekukurumidza pasina kuchengetedza rakawandisa simba mubhatiri.
Vagadziri vemotokari vanofanirwa kufunga akati wandei akakosha dhizaini kana uchisarudza DBR yemagetsi mota application.Kune ese emagetsi emagetsi mota (angave bhatiri kana mafuta cell) , kuita kuti zvikamu zvive zvakareruka uye compact sezvinobvira chinhu chekutanga chinodiwa dhizaini.
Iyo modular solution, zvichireva kuti anosvika mayunitsi mashanu anogona kusanganiswa muchikamu chimwe kuti asangane kusvika ku125kW yezvinodiwa zvemagetsi.
Uchishandisa nzira dzemvura-yakatonhorera, kupisa kunogona kubviswa zvakachengeteka pasina kudikanwa kwezvimwe zvikamu, senge mafeni, senge air-cooled resistors.
