Key Takeaways

• Battery Degradation is Non-Linear: Voltage sag kubva mukuchembera lead-acid kana kusachengetedzwa zvakanaka lithium packs ndiyo mutyairi wekutanga wekurasikirwa nemagetsi kamwe kamwe.
• Thermal Throttling Inodzivirira Dhiraivha: Kunyanya tembiricha inomanikidza mutongi wemotokari kudzikamisa yazvino, yekudzivirira kuita kwekuita kudzivirira kukuvara zvachose.
• Tsanangudzo Kufananidza Kwakakosha: Kushanda kunze kweiyo yakatarwa payload miganho exponentially inomhanyisa chikamu chekupfeka.
• Supplier Sarudzo Inotungamira Hupenyu: Kudyidzana neyakasimbiswa yakaderera inomhanya mota yemagetsi mutengesi inovimbisa kuwana yakasimba Battery Management Systems (BMS) uye yakavimbika waranti yekuvhara.

Basa reBattery State of Health (SOH) uye Voltage Sag

Vafambisi vezvikepe vanowanzovhiringa bhatiri rakazadzwa zvizere nebhatiri rine hutano. Ichi chikanganiso chinowanzoitika uye chinodhura. Chiratidziro chebhatiri chinoratidza 100% mamiriro ekuchajisa (SOC) inongoratidza danho razvino rekuzadza zvichibva pane iripo. Nekudaro, bhatiri rakaderedzwa rine yakaderera zvakanyanya huwandu hwese. Isu tinodaidza iyi metric kuti State of Health (SOH). Kana iwe uine 100% SOC pabhatiri rine 50% SOH chete, iwe uchange uchingosangana nekushaya torque zvisingaite. Motokari yako inongoshaya simba rekuita.

Lead-Acid vs. Lithium-Ion Degradation Curves

Lead-asidhi mabhatiri anopa zvinhu zvakaomarara sezvaanokura. Nokufamba kwenguva, lead sulfate makristasi anovaka pamahwendefa ebhatiri. Iyi sulfation inowedzera zvakanyanya kupikisa kwemukati kwebhatiri. Paunotyaira uchikwidza, mota inoda kukwira kukuru kweazvino. Nekuda kwekukwirira kwemukati, bhatiri voltage inodonha zvakanyanya. Ichi chiitiko chinozivikanwa se voltage sag. Kuderera kwemagetsi kwakanyanya kunokonzeresa kupera simba kamwe kamwe, zvichisiya vatyairi vachikambaira vachikwira zvikomo.

Sezvineiwo, yemazuva ano lithium-ion chemistries inopa akasiyana mabhenefiti. Lithium Iron Phosphate (LiFePO4) mapaketi anoburitsa yakanyatso nyoro yekuburitsa curve. Ivo vanochengeta anowirirana voltage mazinga kunyangwe pasi pemitoro inorema yemuviri. Iyi curve yakatsetseka inovimbisa kuenderana kwemota kubuda kusvika paki yapotsa yapera. Iwe hausi kuona kuita kweusimbe kwakafanana sekudonha kwebhatiri.

Iko Kukanganisa kweBattery Battery Management System (BMS)

Lithium mabhatiri anoda uropi hwemagetsi kuti hushande zvakachengeteka. Isu tinodaidza iyi Battery Management System (BMS). A subpar BMS inotadza kuenzanisa masero ega ega emagetsi nemazvo. Nokufamba kwenguva, mamwe masero anowandisa asi mamwe anowedzera kubuda. Kana iwe uchimhanyisa, iyo isina simba sero inokonzeresa yakaderera-voltage alarm. Iyo BMS inobva yaisa chiratidzo chemotor controller kuti ipinde limp mode nguva isati yakwana. Izvi zvekugadzira zvinovhara kumhanya kwako kuchengetedza iyo isina kusimba sero.

Paunenge uchiongorora a yakaderera kumhanya mota yemagetsi , iwe unofanirwa kuongorora iyo BMS nekungwarira. Tarisa uone maitiro maviri akakosha ekuongorora. Chekutanga, tarisa inoshanda sero balancing, iyo inoshandura simba pakati pemasero zvine simba. Chechipiri, simbirira pane chaiyo-nguva yekukanganisa diagnostics. Diagnostics inobatsira vanamazvikokota kuona maseru anokundikana vasati vakanganisa mashandiro ezvikepe.

Thermal Management Kutadza uye Controller Throttling

Zvinhu zvemotokari yemagetsi zvine miganhu yekupisa. Tembiricha yakakwira inoparadza magetsi uye inosvibisa magineti. Naizvozvo, kutungamira kwekupisa kwakakosha pakuita kwemotokari kunoenderana. Kana tembiricha dzichikwira, motokari dzinoshingaira kuderedza simba radzo. Iyi nzira yekuzvichengetedza inonzi thermal throttling.

Kuramba kwakakwira-torque kunoburitsa kupisa kwakanyanya. Kukweva turera dzinorema kana kukwira mawere emawere kunokonzera kupisa kwemukati mechikamu. Iyo mota windings uye tembiricha yekudzora mota inokwira nekukurumidza. Kuti udzivise zvikamu zvemukati kubva pakunyunguduka chaiko, mutongi anodzikamisa simba rekupa. Iwe unodzvanya pedal zvachose pasi, asi mota inopindura zvishoma nezvishoma. Mutongi ari kungochengetedza drivetrain.

Zvinhu zvekunze zvemamiriro ekunze zvakare zvinokanganisa zvakanyanya kuita. Yakanyanya mamiriro ekunze anosundira zvinhu kunze kwekwazvo mahwindo ekushanda.

• Cold Weather Impact: Kutonhora kwechando kunowedzera mukati mebhatiri kuramba. Electrochemical reactions inononoka zvakanyanya. Izvi zvinonyatso dzikisa yako iripo yekuburitsa huwandu nekusvika makumi matatu%. Motokari inonzwa yakashata kubva pakutanga.
• Kupisa Kwemamiriro ekunze Impact: Tembiricha yakakwira ambient inomhanyisa lithium-ion cell degradation. Mutongi anotanga pedyo nepamusoro pemuganhu wayo wekupisa. Izvi zvinokonzeresa kukurumidza kupisa kwekupisa kunyangwe panguva yekutyaira kwakajairika.

Pane njodzi huru yekushandisa pano. Kutadza kuzvidavirira nezvemamiriro ekunze enzvimbo yako paunenge uchiongorora zvakatemwa zvinotungamira kumatambudziko akakomba. Fleet dzinowanzo shanda zvakanyanya panguva yechando chepamusoro kana mwedzi yezhizha. Vatengi vanofanirwa kuonesa mashandiro emafuta ekushanda vasati vasaina maodha ekutenga.

Mechanical Inefficiencies uye Drivetrain Drag

Hakusi kurasikirwa kwese kwekuita kunobva kunyaya dzemagetsi. Mechanical friction inogadzira yakavanzika parasitic drains pabhatiri rako. Friction inomanikidza mota yemagetsi kukwevera zvakanyanya amps akakwira kuti ichengetedze kumhanya kwakafanana. Yakakwira amp dhizaini inotungamira kukurumidza kupera kwebhatiri uye kuwedzera kupisa kushushikana.

Common Mechanical Culprits

Mechanical kudhonza kazhinji kunobva mukushaikwa kwemaitiro ekugadzirisa. Akabatwa mabhureki mabhureki kana mabhureki asina kunyatsogadziridzwa anogadzira kuramba kutenderedza. Motokari inogara ichirwisa mabhureki ayo. Unorasikirwa nesimba rekumhanyisa uye kutambisa bhatiri rakakosha.

Kudzvinyirirwa kwetayi chimwe chinhu chinokosha. Matai ari pasi pemhepo anowedzera zvakanyanya kuramba kwako. Mutsindo wevhiri unopwanyika, zvinoda simba rakawanda kuti rienderere mberi. Izvi zvinopedza bhatiri nekukurumidza kupfuura zvaitarisirwa. Saizvozvo, akaderedzwa mavhiri emavhiri anogadzira kukwesha kukuru. Mabheji akashata anoda torque yakakwira zvakanyanya kuti utange kufamba.
