21700 is the battery model. The general capacity of this model ternary lithium battery is 3000-5000mAh, and the platform voltage is 3.65V. Then the capacity of 3S12P is 36Ah-60Ah, and the Platform voltage is 3.65 V. about 11V.
Assuming the capacity of the single battery is 3000 mAh (i.e. 3 Ah), the capacity of the 12P battery is 36 Ah. Due to the welding of the cylindrical battery tabs, the charging rate is slightly lower. estimated based on the rate of 0.5C, it can support a current load of 18Ah. Then charging with a current of 10 A poses no problem.
It depends on the battery capacity. If the capacity of a single battery is more than 2000 mAh, charging with 10 Ah will generally not be a problem if the battery has good performance or the capacity reaches more than 4000 mAh. , recharging with 20Ah or more will be permitted.
The baDon't Tesla batteries use lithium?
The rated capacity of this Sony vtc6a 21700 battery is 4000mah, which means it is a 4A battery with a rated voltage of 3.6. v. Fully charged, it's 4.2V. If it's a 10 series (make sure it's a 10 series and not 10 series in parallel), that's- i.e. 10 batteries in series together, then it is a 36v4a battery. This battery can only use 36v0.5a charger, which is more suitable if used in an electric vehicle, it should not be a single series, but at least 10 series and 3 parallel, i.e. 36v12a. a 1-2a charger.
Don't Tesla batteries use lithium? Tesla batteries do not use lithium:
1. Tesla uses the 18650 battery produced by Panasonic. After the Model 3 officially went into production, the new 21700 battery was created. will replace 18650 and become a new battery ;
2. The 21700 battery is a ternary lithium battery, and the cathode material is lithium nickel cobalt aluminate (NCA). This cylindrical ternary battery is currently the highest energy density power battery solution. Compared to square batteries, although this type of battery has high energy density, it is less stable and requires the support of a better BMS (battery management system);
3. Under existing conditions, its production is impossible. The energy density of the 21700 battery system is approximately 300 Wh/kg, approximately 20% higher than the 250 Wh/kg of the original 18650 battery system. At the same time, according to Panasonic's power lithium battery cell test data, the volume energy density of its 21700 battery is much higher than that of the 18650 battery cell.
