EMU2000-Smart Lithium Battery Management System

Likupezeka mu 3 linanena bungwe modes

(1) Njira yowongoka: Kutembenuka kwa DC kwa mabatire anzeru a lithiamu kumatengera njira yolunjika yolipiritsa ndi kutulutsa, ndipo voteji ya module ya batri imalumikizidwa ndi voteji ya busbar.(Zindikirani: Njira yokhazikika yogwirira ntchito).

(2) Boost mode: Batire yanzeru ya lithiamu imathandizira kutulutsa kwamagetsi kosalekeza.Pakakhala kulumikizana pakati pa batire ndi magetsi, voteji ya doko ndi 48 ~ 57V (ikhoza kukhazikitsidwa);pamene palibe kuyankhulana pakati pa batri ndi magetsi opangira magetsi, mtundu wamagetsi a doko ndi 51 ~ 54V (akhoza kukhazikitsidwa), ndipo mphamvuyo si yochepera 4800W.

(3) Sakanizani ndi machesi mode: Smart lithiamu imalowa m'malo otulutsa voteji nthawi zonse molingana ndi kusintha kwamagetsi kwa basi yamagetsi, yomwe imatha kuzindikira kutulutsa koyambirira kwa kugwiritsa ntchito anzeru a lithiamu.Mphamvu ya mains ikadulidwa, batire yanzeru ya lithiamu imatulutsidwa mwakufuna.Kuzama kwa batire yanzeru ya lithiamu kumatha kukhazikitsidwa (DOD yosasinthika ndi 90%).) kutulutsa, pamene mabatire ena a lithiamu (lead-acid) atulutsidwa kumunsi kosalekeza voteji ya anzeru lithiamu batire paketi, wanzeru lithiamu batire adzakhala kutulutsidwa kachiwiri mpaka anzeru lithiamu otsika-voltage chitetezo, anzeru lithiamu sipadzakhalanso kutulutsidwa. , mabatire ena a lithiamu (lead-acid) Pitirizani kutulutsa.

Kuzindikira mphamvu ya ma cell ndi batri:

Kuwona kwamagetsi kwa selo ndi ± 10mV pa 0-45 ° C, ndi ± 30mV pa -20-70 ° C kwa batri yamagetsi ndi kutulutsa kwatsopano.Kuyika kwa ma alarm ndi magawo achitetezo kungasinthidwe kudzera pakompyuta yolandila, ndipo cholumikizira chapano chomwe chimalumikizidwa ndi dera lalikulu lamalipiro ndi kutulutsa chingagwiritsidwe ntchito kusonkhanitsa ndi kuyang'anira kulipira ndi kutulutsa kwapaketi ya batri munthawi yeniyeni, kuti muzindikire alamu ndi chitetezo cha mtengo waposachedwa komanso wotulutsa, molondola kwambiri pa ±1.

Ntchito yoteteza chigawo chachifupi:

Ili ndi ntchito yodziwikiratu komanso yoteteza pamayendedwe amfupi.

Kuchuluka kwa batri ndi nthawi yozungulira: Kuwerengera nthawi yeniyeni ya kuchuluka kwa batri yotsalira, kuphunzira kwathunthu kuchuluka kwa ndalama zonse ndikutulutsa nthawi imodzi, kulondola kwa SOC kulondola kuposa ± 5%.Mtengo wokhazikika wa batri cycle capacity ukhoza kusinthidwa kudzera pa kompyuta yapamwamba.

CAN, RM485, RS485 kulumikizana mawonekedwe:

Kulumikizana kwa CAN kumalumikizana molingana ndi inverter protocol iliyonse ndipo kumatha kulumikizidwa ndi kulumikizana kwa inverter.Yogwirizana ndi mitundu yopitilira 40.

Kulipiritsa ntchito zochepetsera pano:

Njira zochepetsera zomwe zikuchitika komanso zochepetsera, mutha kusankha imodzi malinga ndi zosowa zanu.

(1) Kuchepetsa komwe kulipo: Pamene BMS ikulipira, BMS nthawi zonse imayatsa MOS chubu yochepetsera yomwe ilipo ndipo imachepetsa kuthamanga kwa 10A.

(2) Kuchepetsa kwapakali pano: M'malo othamangitsira, ngati chiwongolero chikafika pamtengo wopitilira alamu, BMS imayatsa 10A yochepetsa ntchito, ndikuwunikanso ngati chojambulira chaposachedwa chikufika pamlingo wocheperako pambuyo pa 5. mphindi zochepetsera pano.(Otsegula chabe malire apano atha kukhazikitsidwa).
