1 Ndingadaidza sei "kukurumidza kuchaja" kana uchichaja? Isu tinobhadharisa chikumbiro chakakosha: 1) Charge inokurumidza; &39;2) Usakanganisa hupenyu hwangu hwebhatiri; 3) Edza kuchengetedza mari, mari yakawanda yemagetsi inosunungurwa, edza kuibhadhara mubhatiri rangu. Saka iwe unogona kukurumidza sei kufona nekukurumidza? Iko hakuna zvinyorwa zvakajairwa zvekupa hushe chaihwo, isu tinoendeswa kwechinguva kune nhamba yezvikumbaridzo inotaurwa mumutemo werubatsiro unonyanya kufarirwa. Tafura inotevera ndiyo itsva simba mutakuri mota 2017 subsidy standard.

Zvinogona kuoneka kuti kukurumidza kuchaja yekupinda nhanho ndeye 3C. Muchokwadi, mune yerubatsiro chiyero chemotokari dzinotakura vanhu, hapana chekuratidzira zvinodiwa. Kubva pane zvekunyepedzera zvemotokari yevafambi, iwe unogona kuona kuti munhu wese anogona kuzara ne80% inogona kushandiswa sekukurumidza kuchaja, uye ivo vanozokwidziridzwa.

Saka, saka, mota yemufambi 1.6c inogona kunge iri yekupinda nhanho Charge referensi kukosha. Zvinoenderana nepfungwa iyi, kukwidziridzwa kuri maminetsi gumi nemashanu akazara ne80%, iyo yakaenzana ne3.

2C. 2 fast charge bottleneck? Muchirevo chechinyorwa chino, mapato akakodzera anotevera zvidzidzo zvemuviri, zvinosanganisira mabhatiri, majaja, uye nzvimbo dzekugovera magetsi. Isu tinokurukura nekukurumidza kuchaja, tichifunga zvakananga kuti bhatiri richava nematambudziko.

Muchokwadi, bhatiri risati rave nematambudziko, chekutanga idambudziko rekuchaja muchina uye mitsara yekugovera. Takataura nezvemurwi wekuchaja weTSLA, zita rayo iguru rekuchaja murwi, simba rayo i120KW. Zvinoenderana nezviyero zveTslamodels85D, 96S75P, 232.

5ah, iyo yepamusoro-soro 403V, ​​1.6C inoenderana neiyo yakanyanya kudiwa simba i149.9kW.

Izvo zvinogona kuoneka kubva pano kuti kune bvunzo yemurwi wekuchaja wemagetsi mota, 1.6C kana 30 maminetsi. Mumitemo yenyika, hazvibvumirwi kuisa zvakananga chiteshi chekuchaja zvakananga mune yekutanga yekugara simba network.

1 murwi wemagetsi wakazadzwa nekukurumidza wakapfuura magetsi edzimba gumi nemaviri. Naizvozvo, ese chiteshi chekuchaja anofanira kuseta 10kV transformer zvakasiyana, uye network yekugovera yedunhu haisi huwandu hutsva hwe10kV substation. Rakadaro bhatiri.

Bhatiri rinogona kutakura 1.6C kana 3.2C yekuchaja zvinodiwa, inogona kutariswa kubva pamativi maviri e macro uye micro.

3 Musoro weiyo yekukurumidza kuchaja theory yekukurumidza kuchaja theory inodaidzwa kuti "Macroable fast charging theory" nekuti yakatemwa zvakananga bhatiri yekuchaja huwandu ndiyo hunhu, microstructure, electrolyte zvisungo zvemukati zvakanaka uye zvisina kunaka electrode zvinhu zvelithium ion mabhatiri. Additives, diaphragm properties, nezvimwewo, zviri mukati meaya madiki mazinga, isu takaiswa kwenguva pfupi kunze kwebhatiri, tichiona kukurumidza kuchaja kwe lithium-ion mabhatiri.

Lithium-ion bhatiri kuvapo, yakanakisa kuchaja ikozvino muna 1972 musayendisiti weUS Jamas inoratidzira kuti bhatiri rine yakanakisa yekuchaja curve panguva yekuchaja, uye yake Mas San Law, zvinofanirwa kucherechedzwa kuti dzidziso iyi inotsanangurwa kune lead-asidhi mabhatiri, inotsanangura Muganho weiyo yepamusoro inogamuchirwa kuchaja ikozvino kubuda kweiyo divi uye mamiriro emhando yemhando diki. Asi iyo sisitimu ine mhinduro yakanakisa, asi ndeye quiz kuti ndiyo. Kunyanya kune lithium ion bhatiri, kutsanangura mamiriro emuganho weiyo yakanyanya kugamuchirwa ikozvino inogona kuve ine zvinoreva zvakare.

Kubva pane mamwe mabhuku ekutsvagisa mhedziso, kukosha kwayo kwakaringana ichiri chimiro checurve chakafanana nemutemo. Zvakakosha kuziva kuti muganhu wepamusoro weti lithium-ion bhatiri, kuwedzera kune zvinhu zve lithium ion battery monomer, kuwedzera kune zvikonzero zvehutano hwehutano, zvakadai sekukwanisa kupisa kupisa, iyo yakawanda inogamuchirwa kutengesa ikozvino yegadziriro yakasiyana. Zvadaro tichaenderera mberi nekukurukura pasi nechikonzero ichi.

Tsanangudzo yeformula yaMaszer: i = i0 * e ^ αt; I0 ndiyo yekutanga kuchaja ikozvino yebhatiri; α chiyero chekugamuchira chekuchaja; T inguva yekuchaja. Kukosha kweI0 uye α uye rudzi rwebhatiri, chimiro uye chitsva uye chekare. Panguva ino, kutsvagisa nzira dzekuchaja bhatiri kwakakosha zvichibva pane yakakwana yekuchaja curve.

Sezvinoratidzwa mumufananidzo uri pasi apa, kana ikozvino yekuchaja ichipfuura iyi yakakwana yekuchaja curve, kwete chete mutengo wechaji haugone kuwedzerwa, asi uchawedzera huwandu hwebhatiri; kana iri pasi peiyi yakanakisa kuchaja curve, kunyangwe isingakuvadze bhatiri, ichawedzera Kuchaja nguva, kuderedza kuchaja kunyatsoshanda. Tsanangudzo yedzidziso iyi inosanganisira nhanho nhatu, inova yerwendo rweMasz: 1 chero ipi zvayo yakapihwa yekuburitsa ikozvino, ikozvino yekuchaja bhatiri mubhatiri inopindirana nekugona kwesimba re α nebhatiri; 2 Nezve chero kuburitswa kwakapihwa Huwandu hwehuwandu, α uye discharge ikozvino ID inoenzanirana; 3 Bhatiri inoburitswa pamitengo yakasiyana yekuburitsa, uye iyo yekupedzisira inotenderwa kuchaja ikozvino IT (inogamuchirika kugona) ihuwandu hweinobvumidzwa yekuchaja ikozvino pane yega yega yekuburitsa. Iyo theorem iri pamusoro ndiyo zvakare sosi yepfungwa yekuchaja yekubvuma kugona.

Kutanga nzwisisa kuti chii chiri kuchaja kugamuchira. Ndakawana denderedzwa uye handina kuona iyo yakabatana official meaning. Zvinoenderana nemanzwisisiro ako pachako, iyo yekuchaja yekubvuma kugona ndiyo yakanyanya ikozvino yekuchaja bhatiri kuchaja pane imwe huwandu hwechaji pasi pemamwe mamiriro ekunze.

Kukanganisa kwezvinogamuchirwa zvinoreva kuti hapana mhedzisiro isingafanirwe kuve nayo, hapana mhedzisiro yakaipa pahupenyu nekushanda kwebhatiri. Uyezve, nzwisisa mitemo mitatu. Mutemo wekutanga, mushure mekunge bhatiri rabudiswa, kukwanisa kubvuma kubhadharisa uye huwandu huripo hwesimba, kuderera kwechaji, kunowedzera kukwanisa kugamuchirwa kwekuchaja.

Mutemo wechipiri, panguva yekuchaja, pulse discharge inogona kubatsira bhatiri kuvandudza chaiyo-nguva yekugamuchira kukosha kwazvino; mutemo wechitatu, kubhadharisa kubvuma kugona kuchakwidziridzwa ne pre-charge uye discharge mamiriro usati wachaja. Kana iyo Mas inokodzerawo mabhatiri e-lithium-ion, iyo reverse pulse kuchaja (iyo chaiyo zita reflex inokurumidza kuchaja nzira mune inotevera] Pamusoro pekuona kweiyo polarization, inobatsira kune tembiricha inokwira kudzvinyirira, Massea inoshandawo. Tsigiro yemaitiro ekupuruzira.

Kupfuurirazve, chokwadi, inzira yakangwara yekuchaja, ndiko kuti, iyo yakangwara yekuchaja nzira, ndiko kuti, iyo yekuchaja ikozvino kukosha kwagara ichichinja nekuda kweMascus curve yelithium-ion bhatiri, kuitira kuti kubhadharisa kushanda kuwedzere mumuganhu wekuchengetedza. 4 Inowanikwa Nekukurumidza Kuchaja Nzira Nzira yekuchaja yemabhatiri e-lithium-ion ine mhando dzakawanda, zvekukurumidza kuchaja zvinodiwa, nzira dzayo dzakakosha dzinosanganisira pulse kuchaja, Reflex kuchaja, uye kuchaja kwakangwara. Mhando dzakasiyana dzebhatiri, nzira dzadzo dzekuchaja hadzina kunyatsofanana, uye chikamu ichi hachiite misiyano chaiyo muchikamu chino.

Pulse charging Iyi ndiyo pulse charger mode kubva mumabhuku, uye pulse phase inopiwa mushure mekuchaja kubata uye yekumusoro muganhu voltage ndeye 4.2V, uye ichienderera ichipfuura 4.2V.

Usataure kurongeka kweiyo chaiyo parameter marongero, akasiyana marudzi emabhechi ane misiyano. Isu tinoteerera kune iyo pulse kuita maitiro. Pazasi pane pulse charging curve, uye zvakakosha kusanganisa matanho matatu: precharge, kugara uchichaja ikozvino uye pulse kuchaja.

Kuchaja bhatiri panguva yakare panguva yekuchaja nguva dzose, simba rechikamu rinoendeswa mukati mebhatiri. Kana bhatiri remagetsi richikwira kusvika kumucheto wepamusoro voltage (4.2V), pinda iyo pulse kuchaja modhi: kuchaja bhatiri ne pulse ikozvino ye1C.

Iyo bhatiri voltage inoramba ichiwedzerwa munguva inogara ichichaja Tc, uye iyo voltage inodonha zvishoma nezvishoma kana kuchaja kwamira. Kana magetsi ebhatiri adonha kusvika kumagetsi epamusoro (4.2V), achichaja bhatiri neukoshi hwazvino, kutanga kutenderera kunotevera kuchaja, kudzokororwazve kusvikira bhatiri razara.

Munguva yekuchaja pulse, kumhanya kwebhatiri voltage kunononoka zvishoma nezvishoma, uye nguva yekumira T0 ichave yakareba. Kana iyo inogara iripo yekuchaja yebasa kutenderera yakadzikira se5% ~ 10%, inofungidzirwa kuti bhatiri rakazara uye rinopera kuchaja. Kana ichienzaniswa neyakajairwa nzira dzekuchaja, iyo pulse charge inogona kuchaja neyazvino yakakura, uye kusungirirwa kwebhatiri mubhatiri rinomira uye ohmic polarization ichabviswa, kuitira kuti kutenderera kunotevera kwekuchaja kuite zvakanaka, kumhanya kwekuchaja kunokurumidza, Tembiricha idiki, inokanganisa hupenyu hwebhatiri, uye ikozvino inoshandiswa zvakanyanya.

Zvisinei, zvipingamupinyi zvayo zviri pachena: simba rekupa kune imwe nzira yerukova ine shoma, iyo yakawedzera mari ye pulse kuchaja nzira. Inopindirana yekuchaja nzira, lithium-ion bhatiri, kubhadharisa kwepakati, kupindirana, kupindirana kwemagetsi nzira, uye inochinja-chinja magetsi inopindirana. 1) Shanduko yeiyo transistream inopindirana yekufambisa nzira inokurudzirwa napurofesa weChen Gongjia, Xiamen University.

Iyo inoratidzirwa nekushandura inogara ichichaja ikozvino kune inorambidzwa ikozvino. Sezvakaratidzwa mumufananidzo uri pasi apa, danho rekutanga rekuchinja kwekuchinja kwekuchinja kwekutanga, uye bhatiri inobhadharwa nehuwandu hwezvino. Kana bhatiri voltage inosvika cutoff voltage V0, kuchaja kunomiswa.

Panguva ino, simba rebhatiri rakaderera zvakanyanya. Mushure mekuchengetedza nguva yekumira, kuderedza kuchaja ikozvino kunoramba kuchichaja. Kana iyo bhatiri voltage inosimudzwa kune cutoff voltage V0, kubhadharisa kunomiswa, kuitira kuti nguva yekudzorera (kazhinji inenge 3 kusvika ku4 nguva) kutengesa ikozvino kunoderedza set cutoff ikozvino kukosha.

Wobva wapinda iyo inogara ichichaja nhanho yekuchaja, bhadharisa bhatiri kubhatiri kusvika iyo yekuchaja yadzikiswa kusvika padanho rezasi, kuchaja kunopera. Musangano mukuru wekuchinja kwemagetsi-kuchinja kubhadharisa kunowedzerwa nemaitiro anopindirana zvishoma nezvishoma anoderedza ikozvino, ndiko kuti, nzira yekuchaja inokurumidza, uye nguva yekuchaja inopfupiswa. Nekudaro, iyi yekuchaja modhi yedunhu yakanyanya kuoma, kudhura kwakanyanya, kazhinji kungofunga kana yakakwira-simba nekukurumidza kuchaja.

2) Kubva pane shanduko yekuchinja kwemagetsi, kune shanduko yemagetsi-isingapindi mutero wepakati. Musiyano uripo pakati pezviviri izvi nhanho yekutanga yekuchaja, uye kuyerera kwepakati kunoshandurwa kuita intermittently. Enzanisa maonero ari pamusoro (a) uye Figure (b), inooneka inogara ichimanikidza inopindirana ichaja inoenderana neyakanakisa yekuchaja curve.

Muchikamu chega chega chekuchaja magetsi, nekuda kweiyo voltage yenguva dzose, ikozvino yekuchaja inodzikiswa zvinoenderana nemutemo weindex, uye mwero wekugamuchirwa webhatiri unodzikiswa zvishoma nezvishoma nekuchaja. REFLEX inokurumidza kuchaja nzira Reflex inokurumidza kuchaja nzira, inozivikanwawo senzira yekuchaja yeratidziro kana "snoring" yekuchaja. Imwe neimwe yemaitiro ekutenderera kweiyi nzira inosanganisira yekuchaja kumberi, reverse kubuda nekukasira uye matanho matatu.

Iyo inogadzirisa polarization yebhatiri mune yakakura uye inomhanyisa kumhanya kwekuchaja. Asi reverse discharge ichapfupisa lithium ion bhatiri hupenyu. Sezvinoratidzwa mumufananidzo uri pamusoro, mune yega yega yekuchaja nguva, yazvino yekuchaja nguva ye2C ndeye gumi yeTC, uyezve iyo TR1 ye0.

5 s, reverse discharge nguva ndeye 1 s TD, nguva yekumira ndeye 0.5 s TR2, imwe neimwe yekuchaja kutenderera nguva ndeye 12s. Sekuchaja, ikozvino kuchaja inozove diki zvishoma.

Intelligent yekuchaja nzira parizvino inzira yekuchaja yepamusoro. Sezvinoratidzwa mumufananidzo uri pazasi, musimboti wayo wakakosha kushandisa DU / DT uye DI / DT kutonga tekinoroji. Nekutarisa bhatiri voltage uye ikozvino increments, bhatiri inochajiswa, dynamic tracking Bhatiri inogamuchirwa yekuchaja ikozvino inoita yekuchaja ikozvino kubva pakutanga kwebhatiri kugamuchirwa.

Nzira dzehungwaru dzakadai, dzinowanzo sanganiswa neyepamberi algorithm tekinoroji senge neural network uye fuzzy control, kuona otomatiki optimization yehurongwa. 5 Charge mode Iyo data yekuyedza inobata chiyero chekuchaja inofananidzwa neiyo inogara iripo yekuchaja nzira uye reverse pulse kuchaja. Constant current kuchaja inochajwa bhatiri mune inongogara iripo panguva yese yekuchaja.

Iyo inogara ichichaja ikozvino inogona kuve yakakura yekuchaja ikozvino, asi nekufamba kwenguva, iyo polarization kuramba inooneka zvishoma nezvishoma uye inowedzera simba rakawanda, zvichiita kuti simba riwedzere kupisa, rinopedza uye rinoita kuti kudziya kwebhatiri kuwedzere zvishoma nezvishoma. Kuenzanisa pulse kuchaja nzira yekugara ichichaja uye pulse kuchaja ipfupi reverse yekuchaja ikozvino mushure menguva yekuchaja. Iyo yekutanga fomu inoratidzwa pazasi.

Mukuita kwekuchaja, kuwedzera kwechinguvana kubuda pulses, kushandiswa kwe depolarization, kuderedza mhedzisiro yepolarization kuramba panguva yekuchaja maitiro. Zvidzidzo zvakanyatso enzanisa mhedzisiro yepulse kuchaja uye kugara uchichaja ikozvino. Tora avhareji yazvino ye1c, 2c, 3c, uye 4c (c yebhatiri yakayerwa kugona kukosha), iyo yakashandiswa mumaseti mana ekuenzanisa kuyedza.

Kuwanda kwesimba rakaburitswa mushure mekunge bhatiri razadzwa nebhatiri. Iyo nhamba inoratidza yazvino uye bhatiri-parutivi voltage waveform ye pulsed ikozvino kana yekuchaja ikozvino iri 2C. Tafura 1 inogara ichiyerera pulse ichichaja data yekuyedza.

Nguva yekupuruzira ndeye 1s, iyo yakanaka pulse nguva ndeye 0.9 s, iyo yakaipa pulse nguva ndeye 0.1s.

ICHAV ivhareji yekuchaja ikozvino, QIN inobhadharwa; qo ndiyo simba rekubuda, η ndiko kushanda kubva pamigumisiro yekuedza mune tafura iri pamusoro, iyo inogara ichichaja uye pulse charging inofungidzirwa, iyo pulse yakaderera zvishoma pane inogara iripo, asi mukati Iro simba rose rebheteri rinonyanya kudarika nguva dzose. 6 Different pulse duty cycle inokanganisa pulse charging Iyo yakaipa ikozvino yekuburitsa nguva inononoka, pane imwe mhedzisiro, uye iyo yakareba nguva yekuburitsa iri, inononoka kuchaja; kana iyo flat flat, iyo unit inochajwa, iyo yakareba nguva yekuburitsa. Sezvinogona kuonekwa kubva patafura iri pasi apa, basa rakasiyana-siyana rinoshanda uye rinobvumirwa kumagetsi rine maitiro akajeka, asi kusiyana kwenhamba hakusi kukuru.

Uye izvi zvine hukama, kune maviri akakosha paramita, yekuchaja nguva uye tembiricha hazviratidzirwe. Naizvozvo, kusarudzwa kwepulse charge kwakakwira kune inoenderera ichichaja ikozvino, uye yakasarudzika sarudzo yebasa kutenderera, iwe unofanirwa kutarisa pakukwira kwekushisa uye kubhadharisa nguva yekuchaja.
