EMU2000-Smart Lithium Battery Management System

Muaj nyob rau hauv 3 tso zis hom

(1) Txoj kev ncaj-los ntawm hom: DC hloov dua siab tshiab ntawm cov roj teeb lithium ntse txais cov hom ncaj qha rau kev them nqi thiab tawm, thiab qhov voltage ntawm lub roj teeb module yog synchronized nrog lub voltage ntawm lub busbar.(Faj seeb: Default ua hauj lwm hom).

(2) Boost hom: Lub roj teeb lithium ntse txhawb nqa qhov hluav taws xob tsis tu ncua.Thaum muaj kev sib txuas lus ntawm lub roj teeb thiab lub hwj huam mov, qhov chaw nres nkoj voltage ntau yog 48 ~ 57V (tuaj yeem teeb);Thaum tsis muaj kev sib txuas lus ntawm lub roj teeb thiab cov khoom siv hluav taws xob, qhov chaw nres nkoj voltage ntau yog 51 ~ 54V (tuaj yeem teeb tsa), thiab lub zog tsis tsawg dua 4800W.

(3) Kev sib xyaw thiab kev sib tw hom: Ntse lithium nkag mus rau lub xeev qhov hluav taws xob tsis tu ncua raws li qhov hloov pauv ntawm lub busbar ntawm lub zog hluav taws xob, uas tuaj yeem paub txog qhov tseem ceeb ntawm cov ntse lithium thawj siv.Thaum lub zog tseem ceeb raug txiav tawm, lub roj teeb lithium ntse yuav raug tso tawm zoo dua.Qhov tso tawm qhov tob ntawm lub ntse lithium roj teeb tuaj yeem teeb tsa (lub neej ntawd DOD yog 90%).) tso tawm, thaum lwm cov roj ntsha lithium (lead-acid) raug tso tawm mus rau qhov qis qis ntawm cov roj teeb lithium ntse, lub roj teeb ntse lithium yuav raug tso tawm dua kom txog thaum lub ntse lithium qis-voltage tiv thaiv, lub ntse lithium tsis tso tawm lawm. , lwm cov roj teeb lithium (lead-acid) Txuas ntxiv mus.

Cell thiab roj teeb ntsuas hluav taws xob:

Qhov ntsuas hluav taws xob ntsuas qhov tseeb ntawm lub xov tooj ntawm tes yog ± 10mV ntawm 0-45 ° C, thiab ± 30mV ntawm -20-70 ° C rau roj teeb them thiab tso tawm tam sim no.Kev teeb tsa tus nqi ntawm lub tswb thiab kev tiv thaiv tsis tuaj yeem hloov pauv los ntawm lub khoos phis tawj tswj hwm, thiab qhov ntsuas tam sim no tiv thaiv txuas nrog lub ntsiab hluav taws xob ntawm kev them nqi thiab tawm tuaj yeem siv los sau thiab saib xyuas cov nqi thiab tawm tam sim no ntawm lub roj teeb pob hauv lub sijhawm, kom paub txog lub tswb thiab tiv thaiv tus nqi tam sim no thiab tawm tam sim no, nrog rau qhov tseeb tam sim no ntawm ± 1.

Short circuit tiv thaiv muaj nuj nqi:

Nws muaj kev tshawb nrhiav thiab kev tiv thaiv kev ua haujlwm ntawm cov zis luv luv Circuit Court.

Roj teeb muaj peev xwm thiab lub voj voog lub sij hawm: xam lub sij hawm ntawm lub roj teeb uas tseem tshuav, ua tiav kev kawm ntawm tag nrho cov nqi thiab tso tawm muaj peev xwm hauv ib qho mus, SOC kwv yees qhov tseeb zoo dua ± 5%.Lub roj teeb lub voj voog muaj peev xwm ntsuas tus nqi tuaj yeem hloov pauv los ntawm lub khoos phis tawj sab saud.

CAN, RM485, RS485 kev sib txuas lus interface:

CAN kev sib txuas lus sib txuas lus raws li txhua tus txheej txheem inverter thiab tuaj yeem txuas nrog kev sib txuas lus inverter.Tau tshaj 40 hom.

Charging tam sim no limiting muaj nuj nqi:

Active tam sim no limiting thiab passive tam sim no limiting hom, koj tuaj yeem xaiv ib qho raws li koj xav tau.

(1) Kev txwv tam sim no: Thaum BMS them, BMS ib txwm tig rau ntawm qhov txwv tam sim no MOS raj thiab nquag txwv qhov them tam sim no rau 10A.

(2) Passive tam sim no limiting: Nyob rau hauv lub them nqi, yog hais tias lub them tam sim no mus txog lub them overcurrent tswb, BMS yuav tig rau 10A tam sim no limiting muaj nuj nqi, thiab rov xyuas seb lub charger tam sim no mus txog passive tam sim no limiting mob tom qab 5 feeb ntawm kev txwv tam sim no.(Qhib passive tam sim no txwv tus nqi tuaj yeem teeb tsa).
