Tesla in SeptembeThe energy is increased by 5 times and the power capacity is increased by 6 times. After applied to Tesla, the range can be increased by 16%.


Recently, foreign media insideevs analyzed the charging time and power of Tesla 4680 battery.

In order to understand the 4680 battery more intuitively, insideevs compares it with the 2170 battery currently used in Tesla Model 3.

Data display,The 4680 battery pack can charge from 10% to 80% in 15 minutes, 10 minutes faster than the current Tesla 2170 battery pack.

If the user only needs to charge to 50%, it can be completed in 7 minutes, which is equivalent to the refueling time of traditional fuel vehicles.


In terms of charging power,During the first 6 minutes of charging, the charging power of 4680 battery pack was maintained at 275 kW, and then the charging power began to decrease.Until fully charged, the charging power will remain at about 100kW.

For comparison, the maximum pure electric power of 2170 battery is 250KW. After charging for 3 minutes, the power begins to decline. After charging to 80%, the battery power will even drop below 100kW.


On the whole,The 4680 battery pack can be charged to 44% at 275kw and maintained at 250KW at 50%.

On the contrary, after the 2170 battery is charged to 25%, the charging rate rapidly drops to 150KW, until it drops below 100kW.

It is understood that the Tesla 4680 battery adopts the technology of laser engraving electrodeless ear. The larger the cell size of traditional power battery is, the higher the energy density is, and the longer the driving range of tramcar is. The disadvantage is that the heating is more difficult to control. However, the polar ear in the existing battery is the main component of battery heating.

The structure of stepless ear battery removes the main heating components of the battery, reduces the internal resistance, and makes the higher energy cell possible.

According to musk, Tesla plans to produce 100GWh power batteries by 2022, with a capacity of 3twh by 2030,Excluding the parts purchased from partners Panasonic, LG and Ningde times, the batteries will be produced in Berlin, Germany.
