Menene mai kula da motar mota
Mai kula da motar mota (MCU) shine babban tsarin lantarki na sabbin motocin makamashi, wanda ke tsakanin batirin wutar lantarki da injin tuƙi. Yana da alhakin canza wutar lantarki kai tsaye zuwa wutar lantarki mai canzawa don tuƙi motar don aiki, da kuma daidaita saurin motar, ƙarfin juyi da alkiblarta bisa ga umarnin tuƙi, cimma nasarar sarrafa yanayin farawa, hanzari, birki, hawa da sauran yanayin tuƙi.
Babban aikin
Youdaoplaceholder0 Canza ƙarfin lantarki : Canza wutar lantarki kai tsaye daga batirin wutar lantarki zuwa wutar lantarki mai matakai uku don tuƙa motar AC. Ana samun wannan tsari ta hanyar inverter na ciki, wanda ke amfani da na'urorin canza semiconductor kamar transistor ko IGBTs don sarrafa mita da girman wutar.
Youdaoplaceholder0 Kula da gudu da karfin juyi : Daidaita gudu da karfin juyi na injin bisa ga buƙatun tuƙi (kamar matsayin gear, accelerator, birki), da kuma cimma daidaiton iko ta hanyar fasahar PWM (faɗin bugun jini).
Youdaoplaceholder0 Kariyar tsarin : An sanye shi da kariyar wuce gona da iri, gano kurakurai, kariyar tashar shigar da batir da sauran hanyoyin da za a tabbatar da amincin aikin tsarin.
Youdaoplaceholder0 Maido da kuzari : A lokacin birki, ana iya canza kuzarin motsi zuwa makamashin lantarki ta hanyar tsarin inverter don cajin batirin, ta haka ne za a inganta yanayin tuƙi.
Maɓallan Maɓalli
Module na sarrafa Youdaoplaceholder0 : Yana sarrafa umarnin tuƙi kuma yana samar da siginar PWM don sarrafa inverter.
Module ɗin wutar lantarki na Youdaoplaceholder0 : Ya ƙunshi IGBT da sauran abubuwan canzawa don cimma canjin wutar lantarki.
Na'urar firikwensin Youdaoplaceholder0 : tana sa ido kan yanayin motar (kamar zafin jiki, gudu) kuma tana mayar da ita ga tsarin sarrafawa.
Tsarin watsa zafi na Youdaoplaceholder0 : yana kiyaye yanayin aiki mai kyau a ƙarƙashin yanayin lodi mai yawa.
Aikin mai sarrafa motar yana shafar ƙwarewar tuƙi da ingancin kuzarin motocin lantarki kai tsaye kuma shine babban cibiya da ke haɗa batirin wutar lantarki da injin tuƙi.
Mai kula da motar mota muhimmin sashi ne na motocin lantarki, kuma manyan ayyukansa sun haɗa da:
Gudanar da gudu da karfin juyi
Ana daidaita saurin injin da karfin juyi bisa ga umarni kamar su mai saurin gudu da birki. Ana daidaita ƙarfin lantarki da mita ta hanyar fasahar PWM don cimma daidaiton ƙa'idar gudu, biyan buƙatun tuƙi kamar haɓaka gudu, birki, da hawan dutse.
Canza makamashi da tuƙi
Ana canza wutar lantarki kai tsaye daga batirin wutar lantarki zuwa wutar lantarki mai canzawa don tuƙa motar, kuma ana daidaita alkiblar wutar lantarki ta hanyar inverter don sarrafa juyawar motar gaba da baya. Lokacin birki, ana iya canza kuzarin motsi zuwa makamashin lantarki sannan a dawo da shi zuwa batirin.
Kariyar tsarin da ganewar asali
Kula da sigogi kamar zafin jiki da ƙarfin lantarki na mota, gano kurakurai a ainihin lokacin (kamar zafi fiye da kima da yawan aiki), da kuma ɗaukar matakan kariya don hana lalacewa. A lokaci guda, sadarwa da raba bayanai tare da wasu tsarin (kamar BMS) ta hanyar hanyar sadarwar CAN.
Sarrafa martani mai ƙarfi
Ana daidaita juyi da kwararar maganadisu daban-daban ta hanyar tsarin sarrafa vector don cimma saurin amsawa ga umarnin tuƙi. Sauyawa mai sauƙi yayin farawa/tsayawa don rage jin girgiza.
Kurakuran mai sarrafa motar a cikin sabbin motocin makamashi galibi suna bayyana ne a matsayin raguwar aikin wutar lantarki, wahalar farawa, ƙaruwar amfani da makamashi da sauran matsaloli. Ya kamata a yi cikakken bincike kan takamaiman dalilan tare da abubuwan da suka faru na kurakurai.
Bayyanar Laifukan da Aka Fi Sani
Youdaoplaceholder0 Rage aikin wutar lantarki : Fedalin mai saurin gudu yana amsawa a hankali, wanda hakan ke sa abin hawa ya yi wa gudu da kuma iyakance saurin da ya kamata.
Youdaoplaceholder0 Farawa mara kyau : Akwai yiwuwar samun matsala wajen farawa, yunƙurin farawa da yawa da suka gaza, ko kuma sautuka/girgiza marasa kyau yayin farawa.
Youdaoplaceholder0 Ƙara yawan amfani da makamashi : Lalacewar na'urar sarrafawa na iya haifar da raguwar ingancin injina da kuma rage yawan abin hawa.
Alamar nuna alamar lahani ta Youdaoplaceholder0 : Allon kayan aiki yana nuna hasken matsalar tsarin wutar lantarki ko hasken matsalar tsarin motar.
Hanyar ganewar laifuffuka
Youdaoplaceholder0 Gwaje-gwajen asali :
Duba ko ƙarfin wutar lantarki na al'ada ne (yi amfani da na'urar multimeter don auna ko ƙarfin wutar lantarki na 5V ba shi da kyau)
Ka lura ko akwai wani yanayi mai zafi sosai a cikin babban da'irar mai sarrafawa (bututun canza MOS guda 6)
Gano siginar Youdaoplaceholder0 :
Auna canjin ƙarfin lantarki lokacin juya maƙallin (zagayen al'ada: 0-4.2VDC)
Duba ko wayoyin da ke haɗa sun lalace ko sun lalace
Gwajin madadin Youdaoplaceholder0 :
Idan juriyar keken turawa ta ɓace bayan cire layukan matakai uku masu kauri na injin, yana iya zama matsalar mai sarrafawa
Yi amfani da kayan aikin ƙwararru (kamar multimeter) don gwada sigogi kamar diode da ƙarfin lantarki mai ƙarfi
Binciken Dalilan Laifi
Youdaoplaceholder0 Lalacewar kayan aiki : Tsufa ko lalacewar da ke ƙara zafi ga na'urorin wutar lantarki na ciki (kamar na'urorin IGBT)
Matsalar haɗin Youdaoplaceholder0 : Layukan sigina marasa ƙarfi da lalacewa suna haifar da asarar siginar sarrafawa
Youdaoplaceholder0 Lalacewar ƙira : ƙarancin ƙirar watsa zafi ko kuma tsarin da bai dace ba na sigogin da'ira
"Idan kana son ƙarin bayani, ci gaba da karanta sauran labaran da ke wannan shafin!
Don Allah a kira mu idan kuna buƙatar irin waɗannan kayayyaki.
