Kodi SoH (State-of-Health) ya batri ndi chiyani?
State-of-health (SoH) ndi State-of-Charge (SoC) ndi zizindikiro zazikulu za khalidwe monga zimapereka deta yothandiza kwambiri yofunikira kukhathamiritsa kwa Battery Management System (BMS).
State-of-charge ndi chikhalidwe chaumoyo ndi magawo osiyanasiyana omwe nthawi zina amatha kusokonezeka. Cholinga cha nkhaniyi ndikutanthauzira momveka bwino teremu iliyonse ndikufotokozera kufunika kwake ndikugwiritsa ntchito.
Boma laumoyo (SoH ya batire imalongosola kusiyana pakati pa batire yomwe ikuphunziridwa ndi batire yatsopano ndikuganizira kukalamba kwa cell.
Imatanthauzidwa ngati chiŵerengero cha kuchuluka kwa batire kwa kuchuluka kwake komwe kudavotera. Ikufotokozedwa ngati peresenti monga momwe tawonera pansipa.
Qmax/mAh= Kuchuluka kwa batire komwe kulipo
Cr = Mphamvu yovotera
Chithunzi 2: Chisinthiko cha SoH cha batri paukalamba
Mbiri yotulutsidwa ya batri yachiwiri imakhudzidwa ndi thanzi lake. Kutsika kwa SoHSoH, batire imatulutsidwa mofulumira monga momwe ikusonyezedwera mu Chithunzi 3 pansipa.
Chithunzi 3: U vs. t panthawi ya batri yolipiritsa ndi kutulutsa maulendo osiyanasiyana a SoH
Momwe mungayesere SoC ndi / kapena SoH ndi BioLogic potentiostat / galvanostat kapena batire
Mtengo wa SoC umapezeka poyang'anira kuchuluka kwa batire (kuyezetsa kwapano ndi nthawi). Kuti izi zitheke, njira ya Galvanostatic Cycling yokhala ndi Potential Limitation (GCPL) komanso njira za Chronopotentiometry (CP) ndi Constant Current (CC) ndizoyenera.
Imodzi mwa njira zomwe zilipo zodziwira SoH ndiyo kudziwa kuchuluka kwa ndalama Q zomwe zingathe kusungidwa pa siteji inayake. Choncho, njira ya EC-Lab® kapena BT-Lab® Battery Capacity Determination (BCD) ingagwiritsidwe ntchito pa izi.
