Mabatire a lead{{4}acid amapereka nthawi yofananira yogwira ntchito koma amataya mphamvu yokweza pang'onopang'ono pansi pa 50% SOC, pomwe LFP imasunga mphamvu yamagetsi mosadukizadukiza pamapindi ambiri otulutsa.
Q: Kodi kulipiritsa mwayi kumachepetsa moyo wa batri la forklift?
A: Ya asidi-ya lead, inde. Ikhoza kuchepetsa moyo wozungulira ndi 10-20%. Pamabatire a LFP lifiyamu, kulipiritsa mwayi kumakhala ndi vuto locheperako ndipo kumatha kukulitsa kuwerengera konsekonse pochepetsa kuzama kwa kutulutsa kulikonse.
Q: Kodi chinthu chachikulu chomwe chimakhudza moyo wa batri la forklift ndi chiyani?
A: Kuzama kwa kutulutsa kumakhala ndi mphamvu imodzi yayikulu. Kuchepetsa DOD kuchokera ku 100% mpaka 80% kumatha kukhala moyo wozungulira kawiri pa chemistry ya LFP. Kutentha ndi kuchuluka kwa mtengo ndi zinthu zotsatirazi zofunika kwambiri. Kusasinthika kwa ma cell pakupanga ndi chinthu chofunikira koma chomwe nthawi zambiri chimanyalanyazidwa.
Q: Ndiyenera kusintha liti batire yanga ya forklift?
Yankho: M'malo mwake thanzi likatsika pansi pa 80% ya kuchuluka komwe adavotera. Pakadali pano, nthawi yothamanga pa mtengo uliwonse imakhala yayifupi kwambiri, ndipo chiwopsezo chowonongeka chimachulukirachulukira. Pamabatire a LFP omwe-amagwira ntchito bwino, malirewo amafika pakadutsa 3,000–5,000+ ma cycle.
Kusankha Battery Yopangidwira kwa Moyo Wopambana
Kutalika kwa batri la Forklift si nambala imodzi. Ndizotsatira zochulukirapo pakusankhidwa kwa chemistry, uinjiniya wamapaketi, luntha la BMS, komanso kuwongolera magwiridwe antchito a tsiku ndi tsiku. Ogwiritsa ntchito omwe amapeza moyo wautali kwambiri wautumiki ndi omwe amamvetsetsa zomwe amawongolera komanso zomwe ziyenera kupangidwa kukhala paketi.
Umu ndi momwe Polinovel amayankhira mafunso anayi omwe woyang'anira zombo zonse ayenera kufunsa asanasaine PO:
Cell chemistry ndi kulolerana kofananira
Gulu-Maselo a LiFePO4, osankhidwa kukhala Ochepera kapena ofanana ndi mphamvu ya 3% ndi kupirira kwamkati pamaso pa paketi. Palibe ma cell ophatikizika-kapena B-pagulu lililonse la forklift.
Kukonzekera kwawindo la SOC
BMS yathu imagwiritsa ntchito zenera la 10-90% la SOC mwachisawawa. Izi zimapereka pafupifupi 10% ya mphamvu za nameplate koma zimapereka moyo wautali wozungulira. Zenera likhoza kusinthidwa kuti lizigwiritsidwa ntchito zinazake, koma timalimbikitsa kuti tisakulilitse popanda kuwunikiranso uinjiniya.
Kusamalira kutentha kwa kusungirako kuzizira
Kutentha kophatikizana kwa PTC ndi kokhazikika pamabatire onse ozizira a Polinovel-ndi ma chain forklift batire, ndi BMS-yotsekereza kutseka kwa cell yotsika ndi madigiri 5. Osasankha, osati kuwonjezera-. Yomangidwa mkati.
Deta yam'munda
Deta ya moyo wapanjinga yochokera kuzinthu zofananira ikupezeka mukafunsidwa. Sitikupemphani kuti mukhulupirire nambala ya data. Timapereka gawo-zotsimikizika za SOH zochokera kumachitidwe ofanana ndi anu.
OnaniKukonzekera kwa batri yamagetsi ya Forklift ya Polinovelkuti muwone momwe zisankho zauinjiniyazi zimasinthira kuti zizigwira ntchito kwanthawi yayitali, kapena funsani mainjiniya athu kuti muwonetsetse kuti moyo wanu wazungulira ukugwirizana ndi momwe malo anu amagwirira ntchito.
