We often see 4680 Vs 4695 battery in electric vehicle applications. What is the difference between the two? This article will take you to understand.
What is 4680 battery?
The 4680 battery is a cylindrical lithium ion battery with a diameter of 46 mm and a height of 80 mm. It was first designed by Tesla for commercial electric cars(Model Y). On the other hand, the volume of the 4680 cells is 5.7 times that of a 2170 lithium battery. The biggest advantage of the new Tesla 4680 battery is that it can produce more battery energy capacity with less raw materials in general. As can be seen, the total battery cost may be reduced to half cost of the 21700 battery with the gradual expansion of mass production.
What is 4695 battery?
Like the 4680 battery, the diameter of the 4695 is 46 mm, but there is a difference in height, the height of the 4695 battery is 95 mm. It also belong to NCM lithium ion battery. Specially designed for EVs application.
Difference between 4680 battery and 4695 battery?
Just as above mentioned, the size of the 4680 battery is 68 in diameter and 80mm in height. However,The size of the 4695 battery is 46 in diameter and 95mm in height.
The capacity of 4680 battery is 26000mAh. But the 4695 battery capacity are always more than 30000mah, that means the capacity of 4695 battery are large than 4680 battery typically.
Benefits of tesla 4680 battery
Faster charging speed
Since the all-pole tabs structure, we only takes 20 minutes to charge the 400 V 4680 battery system to 60%. In the future, if the 4680 battery adopts an 800 V voltage system, the charging speed will be faster.
Because the mechanical strength of the 4680 battery is higher, it is more suitable for CTC technology (Cell to Chassis). As shown in the picture below, Tesla has eliminated the battery cover on the 4680 battery array, increasing space utilization. In terms of manufacturing costs, Musk said that after adopting the CTC+ integrated die-casting technology, 370 parts can be saved, the body weight can be reduced by 10%, and the battery cost per kWh can be reduced by 7%.
Longer driven distance
As we mentioned above, the body weight are lighter 10% around since the CTC technology, that means the car can last longer when consuming the same electricity
