Chii chinonzi Battery System Control?
Mubvunzo unouya zvakanyanya kubva kumapoka ekutenga achifananidza makotesheni. Ivo vanozotarisa maviri 48V 400Ah mapakeji, ona maseru akafanana akanyorwa pamapepa ese ari maviri, uye vobvunza kuti sei imwe ichidhura makumi matatu muzana. Mhinduro inenge nguva dzose iri muhurongwa hwekutonga. Asi izvo zvakaoma kutengesa nekuti haugone kutora mifananidzo yekutonga algorithm.
Battery system control ndiyo inorongeka mashandire epeki-kana ichitendera kuchaja, mateedzero aanoita macontactor, angave achienzanisa maseru, mabatiro aanoita kune tembiricha. Masero zvinhu panguva ino. CATL, EVE, CALB-ose anogadzira maseru eLFP ane hunhu. Chii chinotarisisa kuti paki inotora mazana matatu emakumi matatu kana mazana matatu matendereji pasi pekushandiswa kumwe chete kunonyanya kudzika kune kuti maseru aya anofambiswa sei.
Chii Chinoshata
Hechino chimwe chinhu chichiri kushamisa vanhu. Lithium masero haakwanise kubhadhariswa pasi pe0 degree. Kwete "haifanire kuva"-haigone, pasina kukuvara. Chii chinoitika ndechekuti lithium ion haigone kupindirana mugraphite anode kana kuchitonhora. Panzvimbo iyoyo vanoisa kunze sesimbi lithium pamusoro. Izvi ndezvekusingaperi. Sero rinotaridzika zvakanaka, rinochaja zvakanaka, rinoshanda zvakanaka kwemwedzi. Ipapo iwe unowana simba rinopera rinokurumidza, uye pakupedzisira mukati mapfupi kubva kudendrite kukura.
Battery University yakanyorwa makore aya apfuura. Kuedza kwavo kunoratidza kuti nyangwe maseru anobhadhariswa pa-10 dhigirii ane yakaderedzwa ikozvino achiri kuratidza lithium plating pasi pemicroscope. Kukuvadzwa kwacho kunowedzera uye kusingaonekwe kusvika zvadaro.
Saka iyo BMS inofanirwa kumanikidza tembiricha muganho. Kana iwe uchimhanyisa forklift munzvimbo inotonhora yekuchengetera kana mayadhi ekunze munguva yechando, paki inoda kuramba kubhadharisa pazasi pechikumbaridzo. Kwete kungoyambira-kuramba chaiko. Isu tinoisa yedu pa -10 dhigirii cutoff yekuchaja, nekuderedzwa ikozvino pakati -10 dhigirii ne0 dhigirii. Mamwe masisitimu akachipa haana dziviriro iyi zvachose.
Kuchengetera kutonhora uye nechando zvinhu Logistics ndizvo zvakaipisisa pane izvi. Mapakiti anopinda nekubuda munzvimbo dzefiriza, achichaja mumadhoku ekurodha asina kupisa. Vashandisi havafunge nezvazvo nekuti lead{{2}asidhi yanga isingaite izvi.
Pre{{0}nyaya yechaji yakasiyana asi inechekuita-ndeyekutevedzana kwecontactor kwete tembiricha, asi ndechimwe chinhu chinoregwa kuchengetedza mutengo. Paunovhara macontactor kuti ubatanidze bhatiri paki kumutoro, pane imwe nguva iyo capacitance yese padivi remutoro inoda kubhadharisa kumusoro. Kana iwe ukarovera yakazara pack voltage pane yakaburitswa capacitor, unowana ikozvino spikes pamusoro pe1000A kwemamilliseconds mashoma. Zvakakwana kuti weld contactor mazano pamwechete.
A contactor kuti welds akavharwa haigoni disconnect pakiti panguva kukanganisa. Zvinoreva kuti overcurrent protection inomira kushanda.
Mhinduro yacho yakatwasanuka{{0}kuvhara main negative kutanga, wobva wadyisa current kuburikidza ne-charge resistor, tarisa kusvika load voltage yasvika 95% yepack voltage ine stable gradient, wobva wavhara main positive. Zvinotora 2-3 masekondi. Vamwe vanobatanidza vanoisvetuka kuti ichengetedze nguva yekutanga. Inoshanda zvakanaka kusvika isingaite.
Chikamu Chekuenzanisa
Izvi zvinondishungurudza nekuti zvinogadziriswa. Unogona kutenga A-masero egiredhi kubva kune ane mukurumbira muindasitiri yekugadzira mabhatiri eLiFePO4, woabatanidza zvakakwana, uye uchinge uine paki yepakati nekuti kuenzanisa hakuna.
Nyaya ndeyekushivirira kwekugadzira. Masero anobva muboka rimwe chete rekugadzira anosiyana pakuwanda ne1-3%. Ndizvo chete chokwadi. Mune tambo dzakatevedzana, yakaderera-yekukwanisa maseru anoganhura (inorova isina chinhu kutanga) uye yepamusoro-soro-yekukwanisa masero ekuchaja (inotanga zvakazara). Pasina kuenzanisa, uri kushandisa pamwe 90% yeiyo chaiyo paki kugona. Uye iyo sero risina simba rinowedzera kushushikana kutenderera kwese, kukwegura nekukurumidza, kuderera. Positive feedback loop.
Passive balancing inobvisa mari yakawandisa kuburikidza nezvinodzivirira. 50-100mA kazhinji. Kana sero iri 50mAh pamberi pevamwe, iawa yekugadzirisa. Zvakanaka pakuchaja kwehusiku. Asi michina yekubata zvinhu haichaji nehusiku humwe{5}unochaja mukana panguva yekuzorora, mhanyisa mashifiti akawanda, chengetedza marori achifamba. Passive balancing haigone kuenderera.
Active balancing inofambisa simba pakati pemasero. Mvura yakakwira, hapana simba rakatambiswa. Mapaketi edu anomhanya anoshanda kuenzanisa pa1A + nekuti maapplication anoida.
Hungwaru hunotevera avhareji yemagetsi pamasero ose{{0}kusvika pa160 mumapakiti makuru-uye inoratidza maseru ari kutsauka kubva kune anorevesa. Kuenzanisa kunoshanda pamusoro pe 3.7V avhareji yesero voltage, panguva yekuchaja, kana pasina kukanganisa mireza iripo. Kana sero rasvika mukati me10mV yeavhareji, rinobuda mumutsara wekuenzanisa.
Musiyano unoratidzwa mu-nguva refu yekuchengeta. Mapaketi ane kuenzanisa kwakanaka anogara mukati me20mV sero-ku-mutsauko wesero pazviuru zvemacycles. Mapakiti asina iyo anokukurwa kuenda ku100mV + musiyano mukati megore, zvinoreva kuderedzwa zvakanyanya kugona kushandiswa.
Thermal Response
Wese munhu anoziva nezveyambiro-yakakwirira yematembiricha-55 madhigirii, 60 madhigirii kudzimwa. Chikamu chinobatsira ndechekuti iwe unopindura sei pasina kungouraya michina.
Forklift iri pakati peimba yekuchengetera zvinhu ine mutoro pamaforogo haifanire kungovhara nekuti tembiricha yarova chikumbaridzo. Izvo zvine ngozi. Chaunoda kudzikisira zvishoma nezvishoma-kudzikisa zvikumbiro zvazvino sezvo tembiricha inokwira, rega opareta apedze basa nemagetsi akadzikiswa, wobva wamanikidza nguva yakadzikama-kudzika.

Yedu yekudziya logic monitors pamapoinzi akawanda pamodule nekuti tembiricha yekushisa mukati mepakeji inogona kurova 15℃pasi pemutoro unorema. Imwe sensor yepakiti yese haikuudze chero chinhu chinobatsira. Kana imwe module ikaramba ichipisa nemadhigirii gumi pane mamwe, izvo zvinowanzokwidziridza kuramba mukati mumasero iwayo-yambiro yekukurumidza yedambudziko ririkuitika. Isu tinocherekedza misiyano pamusoro pegumi dhigirii yekuferefeta.
Iwo madhigirii ekupindura akaturikidzana: pamusoro pe 45 dhigirii, kuderedza kubhadharisa ikozvino. Pamusoro pe55 dhigirii, yambiro pamwe nekuburitsa kudzikira. Pamusoro pe60 dhigirii, inodzorwa yekuvhara kutevedzana. Pamusoro pe65 dhigirii, paki yakamisikidzwa sekutadza kumirira kuongororwa. Nhanho imwe neimwe inopa ruzivo rwemushandisi uye sarudzo pane kungocheka simba.

Kana isu tichitaura nevatengi tichienzanisa lithium bhatiri pack suppliers, iyo hurukuro inowanzotanga nesero specs uye mutengo. Kuyenzerana. Asi pane imwe nguva unotofanira kubvunza nezve control logic-kuti ndeipi tembiricha cutoffs, ndeipi nzira yekuenzanisa pane yazvino, ndeipi pre-kutevedzana kwechaji. Mhinduro dzinokuudza kana uri kutarisa mhinduro dzakagadzirwa kana mutengo-mabhokisi akaderedzwa.
IEC 62619 inovhara indasitiri lithium mabhatiri emaforklifts, AGVs, irwo rudzi rwechinhu. Inoda kushanda kwekuchengetedzwa kwekuongorora. Asi mapaketi maviri anogona kupfuura 62619 uye ane akasiyana zvachose ekudzora sophistication. Muyero iuriri, kwete sirin'i.
Zvakadaro. Masero anowana kutariswa kwese. Iyo control system inoita yakawanda yebasa.
