Taolo ea enjene ea likoloi ke eng
Taolo ea enjene ea likoloi (MCU) ke module ea mantlha ea elektroniki ea likoloi tse ncha tsa eneji, e pakeng tsa betri ea motlakase le enjene e khannang. E ikarabella haholo bakeng sa ho fetola motlakase o tobileng hore e be motlakase o fapanyetsanang ho khanna enjene hore e sebetse, le ho fetola lebelo la enjene, torque le tataiso ka matla ho latela litaelo tsa ho khanna, ho fihlella taolo ea maemo a ho qala, ho potlakisa, ho brake, ho hloa le a mang a ho khanna.
Mosebetsi oa mantlha
Phetoho ea Voltage ea Youdaoplaceholder0 : Fetola motlakase o tobileng ho tloha betring ea motlakase ho ea motlakaseng o fetohang oa mekhahlelo e meraro ho khanna enjene ea AC. Ts'ebetso ena e finyelloa ka inverter ea kahare, e sebelisang lisebelisoa tsa ho fetola semiconductor tse kang li-transistors kapa li-IGBT ho laola maqhubu le bophahamo ba motlakase.
Youdaoplaceholder0 Lebelo le taolo ea torque: Fetola lebelo la enjene le torque ho latela litlhoko tsa ho khanna (joalo ka boemo ba gear, accelerator, brake), 'me u fihlelle taolo e nepahetseng ka theknoloji ea PWM (pulse width modulation).
Tšireletso ea sistimi ea Youdaoplaceholder0: E na le tšireletso e feteletseng, ho lemoha liphoso, tšireletso ea seteishene sa ho kenya betri le mekhoa e meng ho netefatsa ts'ebetso e sireletsehileng ea sistimi.
Youdaoplaceholder0 Ho hlaphoheloa ha matla : Nakong ea ho brake, matla a kinetic a ka fetoloa matla a motlakase ka ts'ebetso ea inverter ho tjhaja betri, ka hona ho ntlafatsa sebaka sa ho khanna.
Likarolo tsa bohlokoa
Mojule oa taolo oa Youdaoplaceholder0 : O sebetsana le litaelo tsa ho khanna le ho hlahisa matšoao a PWM ho laola inverter.
Mojule oa matla oa Youdaoplaceholder0 : E na le IGBT le likarolo tse ling tsa ho fetola motlakase ho fihlela phetoho ea motlakase.
Sensor ea Youdaoplaceholder0 : e lekola boemo ba enjene (joalo ka mocheso, lebelo) ebe e e khutlisetsa tsamaisong ea taolo.
Sistimi ea ho qhala mocheso ea Youdaoplaceholder0 : e boloka mocheso o tsitsitseng oa ts'ebetso tlas'a maemo a boima ba mojaro.
Tshebetso ya molaoli wa enjene e ama ka kotloloho phihlelo ya ho kganna le bokgoni ba ho sebedisa eneji ba dikoloi tsa motlakase mme ke setsi sa bohlokwa se hokahanyang betri ya motlakase le enjene ya ho kganna.
Taolo ea enjene ea likoloi ke karolo ea bohlokoa ea likoloi tsa motlakase, 'me mesebetsi ea eona e meholo e kenyelletsa:
Taolo ea lebelo le torque
Lebelo le torque ea enjene li fetoloa ho latela litaelo tse kang accelerator le brake. Voltage le maqhubu li laoloa ka theknoloji ea PWM ho fihlela taolo e nepahetseng ea lebelo, ho fihlela litlhoko tsa ho khanna tse kang ho potlakisa, ho brake le matsoapo a ho hloa.
Phetoho ea matla le ho khanna
Motlakase o tobileng o tswang betring ya motlakase o fetolelwa ho ba motlakase o mong ho kganna enjene, mme tsela eo motlakase o tsamaiswang ka yona e fetolwa ka inverter ho laola ho potoloha ha enjene pele le morao. Ha ho brakewa, matla a kinetic a ka fetolwa ho ba motlakase mme a kgutlisetswa betring.
Tšireletso ea tsamaiso le tlhahlobo ea lefuba
Lekola diparamitha tse kang mocheso le motlakase wa enjene, hlahloba diphoso ka nako ya sebele (jwalo ka ho chesa haholo le ho jara boima ba mmele), mme o nke mehato ya ho itšireletsa ho thibela tshenyo. Ka nako e ts'oanang, buisana le ho arolelana data le ditsamaiso tse ding (tse kang BMS) ka marangrang a CAN.
Taolo ea karabelo e matla
Torque le flux ea makenete li fetoloa ka boikemelo ka li-algorithms tsa taolo ea vector ho fihlela karabelo e potlakileng litaelong tsa ho khanna. Phetoho e boreleli nakong ea ho qala/ho emisa ho fokotsa maikutlo a ho tšoha.
Liphoso tsa molaoli oa enjene likoloing tse ncha tsa eneji li bonahala haholo-holo e le ho fokotseha ha ts'ebetso ea motlakase, ho thatafalloa ho qala, keketseho ea tšebeliso ea matla le mathata a mang. Lisosa tse tobileng li hloka ho ahloloa ka botlalo hammoho le liketsahalo tsa phoso.
Lipontšo tse tloaelehileng tsa liphoso
Youdaoplaceholder0 Tshebetso ya matla e theoha : Pedali ya accelerator e arabela butle, e leng se etsang hore ho be thata hore koloi e potlake mme e fokotsa lebelo le phahameng ka ho fetisisa.
Youdaoplaceholder0 Ho qala ho sa tloaelehang : Ho ka ba le bothata ba ho qala, ho hloleha ha boiteko bo bongata ba ho qala, kapa melumo/ho thothomela ho sa tloaelehang nakong ea ho qala.
Youdaoplaceholder0 Tšebeliso e eketsehileng ea matla : Ho hloleha ha molaoli ho ka lebisa ho fokotseng katleho ea enjene le ho khutsufatsoa ha sebaka sa koloi.
Youdaoplaceholder0 Leseli la pontsho ya phoso : Phanele ya sesebediswa e bontsha lebone la phoso ya sistimi ya motlakase kapa lebone la phoso ya sistimi ya enjene.
