EMU2000-Smart Lithium Battery Management System

Inowanikwa mumatatu ekubuda modes

(1) Yakatwasuka-kuburikidza nemodhi: Iyo DC shanduko yeakangwara lithium mabhatiri inotora yakananga modhi yekuchaja uye kuburitsa, uye voltage yebhatiri module inopindirana nevoltage yebhasibar.(Cherechedza: Default working mode).

(2) Boost modhi: Iyo smart lithium bhatiri inotsigira inogara voltage discharge.Kana paine kutaurirana pakati pebhatiri uye simba rekupa, iyo port voltage renji ndeye 48 ~ 57V (inogona kusetwa);kana pasina kutaurirana pakati pebhatiri uye simba rekupa system, iyo port voltage range is 51 ~ 54V (inogona kuiswa) , uye simba harisi Pasi pasi pe4800W.

(3) Sanganisa uye mechi modhi: Smart lithium inopinda inogara voltage discharge state zvinoenderana nekushanduka kwevoltage yebhasibar remagetsi system, iyo inogona kuona kuburitsa kwekutanga kwe smart lithium primary use.Kana iyo mains simba ragurwa, iyo smart lithium bhatiri inoburitswa zviri nani.Kudzika kwekubuda kweiyo smart lithium bhatiri inogona kusetwa (iyo default DOD ndeye 90%).) kuburitsa, kana mamwe mabhatiri e lithium (lead-acid) aburitswa kune yakaderera isingaperi voltage ye smart lithium bhatiri pack, iyo smart lithium bhatiri ichaburitswa zvakare kudzamara iyo smart lithium yakaderera-voltage dziviriro, iyo smart lithium isisiri kuburitswa. , mamwe mabhatiri e-lithium (lead-acid) Ramba uchibudisa.

Kuonekwa kwesero uye bhatiri voltage:

Kurongeka kwemagetsi ekuona kwesero ndeye ± 10mV pa 0-45 ° C, uye ± 30mV pa -20-70 ° C yebhatiri yekuchaja uye kuburitsa ikozvino kuona.Kukosha kwekugadzirisa kwearamu uye zvidziviriro zvekudzivirira zvinogona kuchinjwa kuburikidza nekombuta inomiririra, uye ikozvino yekuona resistor yakabatana nedunhu guru rekuchaja uye kuburitsa inogona kushandiswa kuunganidza uye kutarisa kubhadharisa uye kuburitsa ikozvino kwebhatiri pack munguva chaiyo, kuitira kuti uone iyo alarm uye dziviriro yekuchaja ikozvino uye yekuburitsa ikozvino, ine yakanakisa ikozvino kurongeka pa ± 1.

Short circuit kudzivirira basa:

Iyo ine yekuona uye yekudzivirira basa rekubuda pfupi dunhu.

Battery huwandu uye nguva yekutenderera: Chaiyo-nguva kuverenga kweyakasara bhatiri huwandu, kudzidza kwakazara kwechaji yakazara uye kubuda simba mune imwe kuenda, SOC yekufungidzira iko kuri nani kupfuura ± 5%.Iyo bhatiri cycle capacity parameter set value inogona kuchinjwa kuburikidza nepamusoro komputa.

CAN, RM485, RS485 kutaurirana interface:

CAN kutaurirana kunotaurirana zvinoenderana neimwe inverter protocol uye inogona kubatana kune inverter kutaurirana.Inoenderana neanopfuura makumi mana emhando.

Kuchaja ikozvino yekumisa basa:

Inoshanda ikozvino inodzikamisa uye passive yazvino yekumisikidza modes, unogona kusarudza imwe zvinoenderana nezvaunoda.

(1) Active ikozvino kudzikisira: Kana BMS ichichaja, BMS inogara ichibatidza yazvino yekumisikidza module MOS chubhu uye nekushingairira kudzikamisa kuchaja ikozvino ku10A.

(2) Passive ikozvino kumisa: Mumamiriro ekuchaja, kana iyo yekuchaja ikasvika pakuchaja yakawandisa alarm kukosha, iyo BMS ichabatidza iyo 10A yazvino yekumisa basa, uye tarisa zvakare kuti charger yazvino inosvika pane yazvino yekumisa mamiriro mushure me5. maminetsi ekudzikamisa ikozvino.(Open passive current limit value inogona kusetwa).
