Zakaj nova energetska elektrika uporablja baterije 18650
18650 baterija je zgodnja, zrela in stabilna litij-ionska baterija, ki se pogosto uporablja v elektronskih izdelkih. V preteklih letih so japonski proizvajalci nabrali veliko ustreznih izkušenj v procesu proizvodnje baterij 18650, tako da sta doslednost in varnost proizvedenih baterij 18650 dosegli visoko raven.
Nasprotno pa kaskadne litij{0}}ionske baterije še zdaleč niso zrele, običajne kvadratne baterije, mehke baterije, tudi če velikost, velikost in položaj jezičkov niso enotni, proizvodni proces proizvajalcev baterij ne more izpolnjevati pogojev in večino ročnega nadzora. Konsistentnost baterije je, da baterija ni na ravni 18650. Upravljanje velikega števila celic v seriji in vzporedno ne bo omogočilo, da bi vsaka celica delovala bolje, če je doslednost celic ni na nivoju in celica 18650 lahko reši ta problem.
To sum up, the 18650 battery has a small capacity and a large number of cells (7104 for the S type), but the consistency is good. Cascade cells can be increased (20ah 60ah), and the number of cells can be decreased, but the consistency is poor. In contrast, it is very difficult to invest a lot of manpower and material resources with battery suppliers to improve the production process of cascaded batteries. So when it comes to developing the Roadster and Model S, Tesla's only option is to buy batteries from the market and develop its own battery system. The technical challenge of developing a battery system that manages more than 6,000 units with good consistency should be less than that of more than 200 units with poor consistency. Even if the number of individual batteries increases, it will be easier to manage if they perform reliably.
