EMU1203-12V Lithium LFP Battery Pack BMS
Chiyambi cha Zamalonda
(1) Kuzindikira mphamvu ya ma cell ndi batire
Kutolereni nthawi yeniyeni ndikuwunika mphamvu ya gulu limodzi la ma cell a 4 kuti akwaniritse kuchulukira kwa ma cell ndi ma alarm a undervoltage ndi chitetezo.Kuwona kwamagetsi kwa unit imodzi ndi ≤± 20mV pa -20 ~ 70 ℃, ndipo kulondola kwa voteji kwa PACK ndi ≤± 0.5% pa -20 ~ 55 ℃.
(2) Maselo anzeru amalumikizana
Maselo osalinganiza amatha kukhala okhazikika pakulipiritsa kapena kuyimirira, zomwe zimatha kusintha nthawi yogwiritsira ntchito batire komanso moyo wozungulira.
(3) Ntchito yolipiriratu
Ntchito ya pre-charge imatha kuyambika nthawi yomweyo mphamvu ikatsegulidwa kapena chubu chotulutsa chiyatsidwa.Nthawi ya pre-charge ikhoza kukhazikitsidwa (1S mpaka 7S), yomwe imagwiritsidwa ntchito kuthana ndi zochitika zosiyanasiyana za capacitive katundu ndikupewa chitetezo cha BMS chochepa.
(4) Mphamvu ya batri ndi nthawi yozungulira
Werengetsani kuchuluka kwa batire yotsalayo munthawi yeniyeni, malizitsani kuphunzira kuchuluka kwa ndalama zonse ndikutulutsa nthawi imodzi, ndipo kulondola kwa SOC kuli bwino kuposa ± 5%.Imakhala ndi ntchito yowerengera kuchuluka kwa ndalama ndi kutulutsa.Pamene kuchuluka kwa kutulutsa kwa paketi ya batri ikufika 80% ya kuchuluka kwathunthu, kuchuluka kwa mizere kumachulukidwa ndi chimodzi, ndipo mtengo wa batire wozungulira mphamvu ya batire ungasinthidwe kudzera pakompyuta yolandila.
Chiyambi cha batri, chilengedwe ndi kutentha kwa mphamvu: kutentha kwapakati pa batri 2, kutentha kwa 1 kozungulira, ndi kutentha kwa mphamvu imodzi kumayesedwa kudzera mu NTC.Kuzindikira kutentha ndi ≤±2 ℃ pansi pa -20 ~ 70 ℃.
(5) RS485 kulumikizana mawonekedwe
PC kapena kutsogolo kwanzeru kumatha kuzindikira kuwunika kwa data ya batri, kuwongolera magwiridwe antchito ndi kukhazikitsa magawo kudzera pa telemetry yolumikizirana ya RS485, ma signature akutali, kusintha kwakutali, kuwongolera kutali ndi malamulo ena.
Kugwiritsa Ntchito Ndi Chiyani?
Ili ndi ntchito zoteteza ndi kuchira monga voteji imodzi / pansi pa voteji, voteji yonse pansi pa voltage / over voltage, charge / kutulutsa pakali pano, kutentha kwambiri, kutentha pang'ono komanso kufupipafupi.Zindikirani muyeso wolondola wa SOC ndi ziwerengero zaumoyo wa SOH pakulipiritsa ndi kutulutsa.Pezani mphamvu yamagetsi panthawi yolipiritsa.Kuyankhulana kwa data kumachitika ndi wolandirayo kudzera mukulankhulana kwa RS485, ndipo kasinthidwe ka magawo ndi kuwunika kwa data kumachitika kudzera pamakompyuta apamwamba kwambiri kudzera pamapulogalamu apamwamba apakompyuta.
Ubwino wake
1. Ntchito yosungira:Chigawo chilichonse cha data chimasungidwa molingana ndi kusintha kwa boma kwa BMS.Deta yoyezera mkati mwa nthawi inayake imatha kusungidwa pokhazikitsa nthawi yojambulira.Deta yakale imatha kuwerengedwa kudzera pamakompyuta omwe ali nawo ndikusungidwa ngati fayilo.
2. Ntchito yotenthetsera:Amapereka Kutentha mawonekedwe.Kapangidwe kake kapadera kamagwiritsa ntchito mphamvu yotenthetsera yamagetsi, yomwe imatulutsa 3A pakali pano ndipo imatha kukwaniritsa kutentha kwambiri kwa 5A.
3. Precharge ntchito:Limbikitsani kukhazikika kwa mabatire, pewani mphamvu zamagetsi nthawi yomweyo ndikuteteza chitetezo chaumwini ndi zinthu.Makina apadera a precharge amateteza batire moyenera ndikuwonjezera moyo wautumiki wa paketi ya batri.
4. Kuyankhulana (CAN+485) ntchito:Mawonekedwe omwewo amagwirizana ndi kulumikizana kwa RS485 ndi kulumikizana kwa CAN, ndikupangitsa kukhala ndi zolinga zambiri.
