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 (kutsogolera-acid) amatulutsidwa kumunsi wokhazikika voteji wa anzeru lithiamu batire paketi, anzeru lithiamu batire adzakhala kutulutsidwa kachiwiri mpaka anzeru lithiamu otsika-voteji chitetezo, anzeru lithiamu salinso kutulutsidwa, mabatire ena lithiamu (kutsogolera-asidi) 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 yolandirira, ndipo chotchinga chodziwikiratu chomwe chimalumikizidwa ndi dera lalikulu lachiwongolero ndi kutulutsa chingagwiritsidwe ntchito kusonkhanitsa ndi kuyang'anira kuyitanitsa ndi kutulutsa kwapaketi ya batri mu nthawi yeniyeni, kuti muzindikire alamu ndi chitetezo cha charger pakali pano ndi kutulutsa pakali pano, ndi kulondola kwapakali pano pa ± 1.

Ntchito yoteteza chigawo chachifupi:

Ili ndi ntchito yodziwikiratu komanso yoteteza pagawo lalifupi.

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 othamangitsa, ngati chiwongola dzanja chikafika pamtengo wopitilira alamu, BMS imayatsa ntchito yoletsa 10A, ndikuwunikanso ngati chojambulira chaposachedwa chikufika pamlingo wocheperako pakadutsa mphindi 5 zakuchepetsa kwapano. (Otsegula chabe malire apano atha kukhazikitsidwa).
