Kuti uwedzere kuwedzera hupenyu uye kuita kweiyo lithium-ion mabhatiri, maitiro akakodzera anobhadharisa anokosha. Zvichangobva kuongorora uye maindasitiri anokwikwidza zvakaringana marongero ekuchaja mari yebhatiri Izvi ndizvo zvinoda kuti vashandisi vazive:
ZVINOKOSHA ZVINOKOSHA
- NCM mabhatiri: Chirahwe ku90% kana pazasikwekushandiswa kwezuva nezuva. Ngwarira zvizere zvakabhadharwa (100%) kunze kwekunge zvakakodzera nzendo refu.
- LFP mabhatiri: Ndichiri kubhadharisa zuva nezuva90% kana pazasiyakanaka, avhiki yakazara
- mhosva(100%) inodikanwa kudzokorora mamiriro ekubhadhara (Soc) kufungidzira.
Nei uchidzivirira kuzere kupomerwa kweNCM mabhatiri?
1. Yakakwirira voltage kushushikana inowedzera kusvibiswa
NCM mabhatiri anoshanda pane yakakwirira yepamusoro voltage muganho uchienzaniswa nemabhatiri eLFP. Kubhadhara zvizere mabhatiri aya kunovadzidzisa kune kukwidziridzwa voltage maziso, kukurudzira kushandiswa kwezvinhu zvinoshanda mune cathode. Ichi chiitiko chisinga tsanangurike chinotungamira mukurasikirwa kugona uye kupfuudza bhatiri rese.
2. Serite Imbalance njodzi
Battery mapaketi ane masero akawanda ane zvisingafarire zvisina kufanira nekuda kwekugadzira misiyano uye electrochemical kusarongeka. Kana uchibhadhara kusvika 100%, mamwe masero anogona kuyerera, zvichikonzera kushushikana kwenzanga uye kusvibiswa. Nepo bhatiri manege masisitimu (BMS) anoshingairira chiyero cell voltages, kunyange yakakwira masisitimu kubva kunotungamira mabhureki se tesla uye byd haigoni kubvisa zvizere njodzi iyi.
3. SAST fungidzira matambudziko
NCM mabhatiri anoratidzira steep voltage curve, inogonesa yakajeka soc quatimation kuburikidza neyevhura-redunhu voltage (OVV) nzira. Mukupesana, LFP mabhatiri anochengetedza denda rakapotsa voltage pakati pegumi nemashanu muzana uye 95% soc, kugadzira ocv-based soc kuverenga isina kuvimbika. Pasina nguva nenguva zvizere, mabhatiri eLFP anotambura nekudzokorora tsika yavo. Izvi zvinogona kumanikidza ma bS mumigwagwa inowanzodzivirira, kuroverera kushanda uye hutano hwakareba hwebhatiri.
Nei lfp mabhatiri anoda vhiki nevhiki yakazara mari
Iyo vhiki nevhiki 100% yekubhadhara kweLFP mabhatiri anoshanda se "reset" ye bMs. Iyi process inokwana mbozs cell voltages uye inoruramisa isingazvikokota inokonzerwa neyavo yakagadzikana voltage mbiri. Precise soc data yakakosha kune iyo BMS yekuita zviyero zvekudzivirira zvinobudirira, sekudzivirira kupfuurira-discharge kana kurongedza marcha ekubhadhara. Kusvetuka iyi calibration kunogona kutungamira kune yekutanga kukwegura kana kusatarisirwa kuita kwemadonhwe.
Zviitiko Zvakanakisa Zvevashandisi
- NCM Battery varidzi.
- LFP Battery varidzi: Chengetedza zuva nezuva kubhadharisa pasi pe 90% asi simbisa vhiki rizere rizere rekutenderera.
- Vese vashandisi: Dzivisa kakawanda kudzikisira zvakadzama uye kupisa kwakanyanya kuenderera mberi nehupenyu hwebheti.
Nekureva izvi mazano, vashandisi vanogona kuwedzera zvakanyanya kusimba kwebhatiri, uye kuve nechokwadi chekuita kwakavimbika kwemotokari yemagetsi kana masimba ekuchengetedza simba.
Gara uchiziviswa neazvino zvinyorwa zvebhatiri tekinoroji uye maitiro ekusimbisa nekunyoresa kuEnhletter yedu.
