Speaking of 4680 battery cell, you may feel unfamiliar and familiar, 4680 battery cell was first released by Tesla on September 23, 2020, Tesla Battery Day activity, and plans to officially put into production in 2022, but 4680 single battery low voltage, and can not meet the needs of mobile power high-power charging and discharging, at the same time, 46mm diameter, 46mm, 46mm, 46mm, 4680 battery It is also not suitable for applications on handheld devices such as mobile power supplies. However, the 4680 battery, in addition to new energy vehicles, is very suitable for outdoor power applications.
Compared with the traditional 18650 battery and 21700, the power of the Tesla 4680 earless battery is 6 times that of the traditional earless battery. At the same time, the earless technology also reduces the internal resistance of the battery and reduces the loss of the battery in charge and discharge, which is equivalent to improving the discharge efficiency of the battery. Compared with the traditional earless battery, the battery life is increased by 16%, and it also has stronger fast charging ability. This time, the charging head network got the 4680 battery launched by BYD, according to the existing information can not judge whether the BYD 4680 battery is the same as Tesla 4680 in the state of non-cutting, the following charging head network from the charge and discharge, internal resistance, temperature test to fully analyze the performance of this battery.
Appearance introduction：
As usual, let’s take a look at the appearance of this battery cell.
Byd 4680 battery side has the inkjet code:Nominal capacity: 15000mAh@0.5C;
Nominal voltage: 3.2V; Nominal energy: 48Wh;
Ac internal resistance: ≤8mΩ.
