Nzira dzekuverenga

Chii chinonzi soc?

Iyo bhatiri mamiriro ekuchaira (soc) ndiyo ratio yekubhadhara ikozvino inowanikwa kune yakazara kubhadharisa mari yekubhadhara, kazhinji inoratidzwa sepesenti. Nenzira chaiyo kuverenga iyo soc inokosha mune aBattery Management System (BMS)Sezvo inobatsira kuona iyo yakasara simba, kugadzirisa bhatiri kushandiswa, uyekutonga kuchiridza uye kuendesa maitiro, nokudaro achiwedzera hupenyu hwebhatiri.

Nzira mbiri huru dzinoshandiswa kuverenga iyo soc ndiyo yazvino yekubatanidza nzira uye iyo yakavhurika-yedunhu-circuit voltage nzira. Zvese zviri zviviri zvakanakira uye zvakashata, uye mumwe nemumwe anounza zvimwe zvikanganiso. Naizvozvo, mune zvinoshanda zvinoshandiswa, nzira idzi dzinowanzobatanidzwa kuvandudza chokwadi.

 

1. Yazvino Kubatanidza nzira

Iyo yazvino yekubatanidza nzira inoverenga iyo soc nekubatanidza mhirizhonga uye discharge mafungu. Pakanaka chayo iri mukureruka kwayo, isingadyi calibration. Nhanho dziri seinotevera:

1. Rekodha iyo soc pakutanga kwekubhadhara kana kurasa.
2. Kuyera iyo iripo panguva yekuchaja uye kurasa.
3. Batanidza iyo iripo kuti uwane shanduko yekutarisira.
4. Verenga iyo yazvino soc uchishandisa yekutanga soc uye iyo yekubhadhara shanduko.

Fomula ndeye:

Soc = yekutanga soc + q∫ (i⋅dt)

kupiIni ndori zviripo, Q ndiyo bhatiri kugona, uye DT ndiyo nguva yenguva.

Izvo zvakakosha kuti uzive kuti nekuda kwekuramba kwemukati uye zvimwe zvinhu, iyo yazvino yekubatanidza nzira ine degree rekukanganisa. Uyezve, zvinoda nguva refu yekuchaja uye kumisikidza kuti uwane zvakawanda zvakarongeka.

 

2. Vhura-Circit Voltage nzira

Iyo yakavhurika-redunhu voltage (OCV) nzira inoverenga iyo soc nekuyera buttery's voltage kana pasina mutoro. Kujekesa kwayo ndiko kuwana kwayo kwakakodzera sezvo zvisingade kuyera kwazvino. Nhanho yacho ndeiyi:

1. Gadza hukama pakati pe soc uye ocv zvichibva pane bhatiri muenzaniso uye mugadziri data.
2. Kuyera iyo bhatiri's OCV.
3. Verenga iyo soc uchishandisa iyo Soc-ov hukama.

Cherekedza kuti iyo soc-ov curve inoshanduka nebhatiri yekushandisa uye likespan, inoda kuti nguva yekusagadzikana kuchengetedza chokwadi. Kupesana kwemukati kunobatawo nzira iyi, uye zvikanganiso zvakakoshera zvakakwirira zvinoyerera.

 

3. Kubatanidza ikozvino kubatanidzwa uye ocv nzira

Kuti uvandudze chokwadi, iko kuwanda kwekubatanidzwa uye ocv nzira dzinowanzobatanidzwa. Nhanho dzeiyi nzira ndeiyi:

1. Shandisa iyo yazvino yekubatanidza nzira yekutevera iyo kubhadharisa uye kurasa, kuwana soc1.
2. Kuyera iyo COV uye shandisa iyo soc-ovhukama hukama kuti uverenge kuverenga2.
3. Sanganisa soc1 uye soc2 kuti uwane yekupedzisira soc.

Fomula ndeye:

Soc = k1⋅soc1 + k2⋅soc2

kupiK1 uye K2 uremu zviyero zvinopfupisa kusvika ku1 Kazhinji, K1 yakakura kwenguva refu kubhadharisa / discharge miedzo, uye K2 yakakura kune zvimwe zvakanyatso kuyerwa zviyero.

Calibration uye kururamisa kunodiwa kuti uve nechokwadi chekurongeka kana uchisanganisa nzira, sekurwisa kwemukati uye tembiricha zvakare zvinobatsira.

 

Mhedziso

Iyo yazvino yekubatanidza nzira uye occ nzira ndiyo nzira dzekutanga dzekuverenga, imwe neimwe neyavo zvakanaka uye cons. Kusanganisa nzira dzose dzinogona kuwedzera chokwadi uye kuvimbika. Nekudaro, calibration uye kururamisa kwakakosha kuti isingateerere kutsunga kutsunga.
