Chifukwa Chake Phukusi la Lithium la RV Limasiya Kuchajidwa M'mawa Wozizira
Ma RV omwe amagwiritsidwa ntchito nthawi yozizira amadandaula kamodzi mobwerezabwereza: batire imawerenga mphamvu yonse usiku, kenako imakana kulandira mphamvu m'mawa wotsatira. Izi si vuto - ndi chemistry ya LFP yomwe imachita zomwe iyenera kuchita. Kuchaja maselo a LFP pansi pa 0°C kumayambitsa lithiamu plating, mtundu wa kutayika kwa mphamvu kosatha komwe sikungabwezeretsedwe. BMS yodziwika bwino imaletsa kuchaja pansi pa malire awa m'malo molola kuti izichitike.
Kutulutsa mphamvu pa kutentha kochepa nthawi zambiri kumaloledwa ndi LFP, ndi mphamvu yochepa yomwe ilipo. Vutoli ndi makamaka kutchaja - kuchokera ku mphamvu ya dzuwa, alternator, kapena gombe - pamene paketiyo ikadali yozizira.
Kodi Kulamulira Kutentha Kumachita Chiyani Kwenikweni?
Kukonza si njira yosiyana ya maselo — ndi njira yowongolera kutentha yomwe imamangidwa mu BMS. Dongosolo lowongolera limayang'anira kutentha kwa maselo nthawi zonse. Phukusili likazizira kwambiri kuti lizitha kuyitanitsa bwino, limayatsa dera lotenthetsera lakunja. Maselo akafika pamalo otetezeka ogwirira ntchito, kuyatsa kumayatsidwanso zokha.
Mfundo ziwiri zofunika kuzisiyanitsa momveka bwino, popeza nthawi zambiri zimasokonezeka pa siteji ya RFQ:
- Kutenthachinthuyokha ndi zida zakunja, zomwe zimasankhidwa ndi wopanga paketi malinga ndi kukula kwa paketi ndi kutentha komwe kuli.
- Kutenthamfundo zowongolera— nthawi yoyatsira, nthawi yoyatsiranso chaji — imakhala mu BMS.
BMS yopanda mphamvu yotenthetsera yolumikizidwa imatetezabe maselo molondola (imatseka mphamvu yochepera malire), koma singabwezeretse phukusilo kukhala lokha - RV singathe kuyitanitsa mpaka kutentha kwa mlengalenga kukwera. Kwa RV yomwe imawona kutentha kwanthawi zonse kwa usiku, kusiyana kumeneko ndi kusiyana pakati pa kuyitanitsa mphamvu ya dzuwa kapena ya m'mphepete mwa nyanja m'mawa uliwonse ndi kutaya mphamvu yoyitanitsa usiku uliwonse wozizira.
Kuyesa Dera Lotenthetsera
Mtundu wa DALY wa RV BMS wokhala ndi zombo zowongolera kutentha zomwe zili ndi gawo lowongolera kutentha la 25A ngati mawonekedwe ofotokozera. Izi zimatsimikiza kuchuluka kwa mphamvu yomwe ilipo yoyendetsera gawo lotenthetsera lakunja - mapaketi akuluakulu kapena nyengo yozizira angafune mulingo wosiyana wa gawo lotenthetsera, wofanana ndi mphamvu yowongolera iyi panthawi yokambirana ya RFQ.
| Nsanja | Chiwerengero cha Maselo | Kulamulira Kutentha |
|---|---|---|
| 12V | 4S LFP | 25A gawo lowongolera kutentha (kapangidwe ka referensi); gawo lotenthetsera lakunja lopangidwa ndi wopanga paketi |
| 24V | 8S LFP | |
| 48V | 16S LFP (16.2S/16S ndiye kuchuluka kwa maselo pa nsanja iyi — mwachibadwa 51.2V, kuchuluka kwa magetsi ogwirira ntchito kuposa 15S, komwe kumafanana bwino ndi zofunikira za magetsi a inverter ndi zida zolumikizirana) |
Mafunso Ofunsidwa Kawirikawiri
Q1. Kodi chingachitike n’chiyani ngati nditachaja paketi ya lithiamu ya RV pansi pa kuzizira popanda kutentha?
Kuchaja pansi pa 0°C kumayambitsa kuyika kwa lithiamu pa anode - kutayika kwa mphamvu kosatha komwe kumasonkhana nthawi iliyonse yozizira. BMS yopangidwa bwino imaletsa kuchaja kuchitika pansi pa malire awa, zomwe zimateteza maselo koma zikutanthauza kuti paketiyo sidzalandira kuchaja mpaka itatentha, pokhapokha ngati pali chowongolera kutentha.
Q2. Kodi chinthu chotenthetsera chimabwera ndi BMS?
Ayi. BMS imapereka njira yowongolera ndi kusintha; chinthu chotenthetsera ndi zida zakunja zomwe zimasankhidwa ndi wopanga paketi kutengera kukula kwa paketi, kutentha komwe kumayang'aniridwa, komanso bajeti yamagetsi yomwe ilipo. Tsimikizani kukula kwa chinthucho motsutsana ndi mulingo wa gawo lowongolera kutentha la BMS panthawi ya RFQ.
Q3. Kodi kutuluka kwa madzi m'thupi kungathekebe nthawi yozizira?
Inde. LFP nthawi zambiri imalekerera kutulutsa madzi pa kutentha kochepa, ndipo mphamvu yake yocheperako imapezeka ngati njira yosinthira. Kuletsa kutayira ndi komwe kumafuna kuyang'aniridwa mwachangu.
Q4. Kodi kulamulira kutentha kuli koyenera kwa RV yomwe imawona chisanu chowala nthawi zina?
Pa nthawi zina kutentha komwe kumazizira kwambiri m'malo mokhala ndi kutentha kwa usiku wonse, omanga ena amasankha kuvomereza nthawi zina kutsekedwa kwa chaji m'malo mowonjezera zida zotenthetsera. Uku ndi kusinthana kwa mtengo/zovuta kwenikweni - ganizirani izi motsutsana ndi momwe mukuwonera nyengo komanso momwe mumagwiritsira ntchito m'malo mongoganizira kuti ndi nthawi yokhazikika.
Zokhudza DALY
DALY imapanga ndikupanga makina oyang'anira mabatire a lithiamu a OEMs, opanga mapaketi, ndi ophatikiza, ndi zinthu zomwe zimagwiritsidwa ntchito m'maiko opitilira 130 kuphatikiza kuchita nawo mwachangu msika wa RV ndi zosangalatsa zam'madzi. DALY idakhazikitsidwa mu 2015, imagwira ntchito motsatira machitidwe a ISO 9001 / ISO 14001 omwe amatsatira CE ndi RoHS; mzere wosungira mphamvu uli ndi udindo wa UL Recognised Component (osati satifiketi yonse ya UL system), yokhala ndi zikalata zoperekedwa kuti zithandizire ntchito yotsimikizira mulingo wamakina m'misika yamadera.
Kusankha Kulamulira Kutentha kwa Nyumba Yogwiritsidwa Ntchito M'nyengo Yozizira?
Mtundu wa DALY wa RV BMS wokhala ndi gawo lowongolera kutentha la 25A — R10Q-M — ndiye mawonekedwe ofunikira omangira magetsi m'nyengo yozizira. Gawani nsanja yanu (12V/24V/48V), kutentha kochepa kwa usiku, ndi gwero la chaji (mphamvu ya dzuwa/alternator/gombe), ndipo gulu la mainjiniya la DALY lidzatsimikizira kukula kwa chinthu chotenthetsera poyerekeza ndi mulingo wa gawo lowongolera.
Kuti mudziwe zambiri zokhudza kusankha RV BMS yokhala ndi zisankho zitatu — kuphatikizapo kugwirizana kwa protocol ya RV-C ndi multi-pack paralleling — onani:Kusankha kwa BMS ya RV Lithium Battery: Kugwirizana kwa RV-C, Kugwira Ntchito kwa Nyengo Yozizira, ndi Kukula kwa Ma Paketi Ambiri.
