Kuti uwedzere hupenyu uye kushanda kwemabhatiri e-lithium-ion, maitiro ekuchaja akakosha. Zvidzidzo zvenguva pfupi yapfuura uye kurudziro dzeindasitiri dzinoratidza nzira dzakasiyana dzekuchaja dzemhando mbiri dzebhatiri dzinoshandiswa zvakanyanya: Nickel-Cobalt-Manganese (NCM kana ternary lithium) mabhatiri uye Lithium Iron Phosphate (LFP) mabhatiri. Hezvino izvo vashandisi vanofanirwa kuziva:
Mazano Anokosha
- NCM Mabhatiri: Charge to90% kana pasizvekushandisa zuva nezuva. Dzivisa kubhadharisa kuzere (100%) kunze kwekunge zvichidikanwa kune nzendo refu.
- LFP Mabhatiri: Ndichiri kuchaja zuva nezuva ku90% kana pasiyakanaka, avhiki nevhiki zvizere
- charge(100%) inodiwa kudzokorora fungidziro yeState of Charge (SOC).
Sei Udzivise Kuchaja Kwakazara kweNCM Mabhatiri?
1. High Voltage Stress Inowedzera Kuparara
NCM mabhatiri anoshanda pamwero wepamusoro wevoltage uchienzaniswa nemabhatiri eLFP. Kuchaja zvizere mabhatiri aya kunovaisa kune yakakwira voltage mazinga, ichimhanyisa kushandiswa kwezvinhu zvinoshanda mu cathode. Iyi nzira isingadzokerike inotungamira mukurasikirwa kwesimba uye inopfupisa hupenyu hwese hwebhatiri.
2. Sero Imbalance Ngozi
Mabhatiri mapaketi ane akawanda maseru ane inherent kusawirirana nekuda kwekusiyana kwekugadzira uye kusaenzana kwe electrochemical. Paunenge uchichaja kusvika ku100%, mamwe maseru anogona kuwandisa, zvichikonzera kushushikana kwenzvimbo nekudzikira. Nepo Battery Management Systems (BMS) inoshingairira kuenzanisa maseru voltages, kunyangwe masisitimu epamberi kubva kune anotungamira mabhureki seTesla neBYD haakwanise kubvisa zvizere njodzi iyi.
3. SOC Estimation Matambudziko
NCM mabhatiri anoratidza kukwirisa voltage curve, achigonesa fungidziro yeSOC kuburikidza neyakavhurika-circuit voltage (OCV) nzira. Kusiyana neizvi, mabhatiri eLFP anochengetedza anenge akadzikama voltage curve pakati pe15% ne95% SOC, zvichiita kuti OCV-based SOC kuverenga kuve kusavimbika. Pasina nguva nenguva yakazara machaji, mabhatiri eLFP anonetsekana kudzokorora hunhu hwavo hweSOC. Izvi zvinogona kumanikidza iyo BMS kuita inogarodzivirira modhi, kukanganisa kushanda uye kwenguva refu yehutano hwebhatiri.
Nei mabhatiri eLFP Achida Vhiki Yese Yakazara Mari
Iyo yevhiki nevhiki 100% kuchaja kwemabhatiri eLFP inoshanda se "reset" yeBMS. Iyi nzira inoenzanisa maseru voltages uye inogadzirisa kusarongeka kweSOC kunokonzerwa nekugadzikana kwavo voltage profile. Yechokwadi SOC data yakakosha kuti BMS iite matanho ekudzivirira nemazvo, sekudzivirira kuburitsa zvakanyanya kana kukwenenzvera kutenderera kuchaja. Kusvetuka chiyero ichi kunogona kukonzera kuchembera nguva isati yakwana kana kudonha kwekuita kusingatarisirwe.
Maitiro Akanakisisa kune Vashandisi
- NCM Battery Varidzi: Isa pamberi pezvishoma kubhadharisa (≤90%) uye chengeta miripo izere yenguva nenguva.
- LFP Battery Varidzi: Chengetedza kuchaja zuva nezuva pazasi 90% asi simbisa kutenderera kwevhiki kwevhiki kuzere.
- Vashandisi Vese: Dzivisa kubuda kwakadzika kakawanda uye tembiricha yakanyanyisa kuti uwedzere hupenyu hwebhatiri.
Nekutora matanho aya, vashandisi vanogona kuwedzera zvakanyanya kusimba kwebhatiri, kuderedza kuderera kwenguva refu, uye kuve nechokwadi chekuita kwakavimbika kwemotokari dzemagetsi kana masisitimu ekuchengetedza simba.
Gara uchiziva nezvezvinovandudzwa patekinoroji yebhatiri uye maitiro ekusimudzira nekunyoresa kupepanhau redu.
