Ke ngoko, bafuna iNkqubo yoLawulo lweBattery eyomeleleyo (BMS) ukuqinisekisa ukhuseleko.
-Iibhetri zeLiFePO4: Nikeza uzinzo olugqwesileyo lwe-thermal kunye nokhuseleko, luqhuba kakuhle nakwiindawo ezinobushushu obuphezulu ngaphandle komngcipheko wokubaleka kwe-thermal. Zifaneleke ngakumbi ukusetyenziswa kwiindawo ezinzima.
3. Ixesha lokuphila
- Iibhetri zeNCM/NCA: Ngokuqhelekileyo zinomjikelezo wobomi be-500-1000 cycles, ezifanelekileyo kwizicelo apho ixesha elide lokuphila lingabalulekanga kodwa ubuninzi bamandla buyimfuneko.
-Iibhetri ze-LiFePO4: Inokuhlala ngaphezulu kwemijikelo engama-2000, izenza zilungele ixesha elide, usetyenziso oluzinzileyo olufana nezibane zeziseko ezingundoqo zoluntu kunye nezibane zasezitalatweni zelanga.
4. Iindleko
- Iibhetri zeNCM / NCA: Iindleko eziphezulu zokuvelisa ngenxa yenkqubo yabo yokuvelisa eyinkimbinkimbi kunye nokuxinana kwamandla aphezulu.
- Iibhetri zeLiFePO4: Iindleko eziphantsi zokuvelisa, njengoko zingenazo isinyithi ezibizayo kwaye zinika umlinganiselo ongcono weendleko zokusebenza.
