In the realm of electric vehicles, the 4680 battery and 4695 battery are frequently compared. This article will provide a comprehensive understanding of their differences and advantages, adhering to Google SEO best practices.
What is the 4680 Battery?
The 4680 battery is a cylindrical lithium-ion battery with a diameter of 46mm and a height of 80mm. Initially designed by Tesla for its commercial electric vehicles like the Model Y, the 4680 battery boasts a volume 5.7 times that of the 2170 lithium battery. The primary advantage of the 4680 battery is its ability to deliver more energy capacity using fewer raw materials. Consequently, as mass production scales up, the overall cost of the 4680 battery could be reduced to half that of the 21700 battery.
What is the 4695 Battery?
Similar to the 4680 battery, the 4695 battery also has a diameter of 46mm but differs in height, measuring 95mm. It belongs to the NCM lithium-ion battery category and is specifically designed for electric vehicle applications.
Differences Between the 4680 Battery and 4695 Battery
Dimensions
As mentioned, the 4680 battery measures 46mm in diameter and 80mm in height. In contrast, the 4695 battery measures 46mm in diameter and 95mm in height.
Capacity
The 4680 battery has a capacity of 26000mAh. On the other hand, the 4695 battery typically has a capacity exceeding 30000mAh, indicating that the 4695 battery generally offers a larger capacity than the 4680 battery.
Advantages of Tesla's 4680 Battery
Faster Charging Speed
Thanks to its all-pole tab structure, the 400V 4680 battery system can reach 60% charge in just 20 minutes. Future advancements could see the 4680 battery utilizing an 800V system, further increasing charging speeds.
Cost Savings
The 4680 battery's higher mechanical strength makes it well-suited for CTC (Cell to Chassis) technology. Tesla has optimized the design by eliminating the battery cover in the 4680 battery array, enhancing space utilization. According to Elon Musk, the adoption of CTC+ integrated die-casting technology can save 370 parts, reduce body weight by approximately 10%, and decrease battery costs per kWh by 7%.
Longer Range
As previously noted, the CTC technology reduces vehicle body weight by about 10%. This weight reduction means that cars can travel further on the same amount of electricity.
Conclusion
In conclusion, both the 4680 battery and the 4695 battery offer distinct advantages and are suited to different applications within the electric vehicle industry. Continuous advancements in technology will ensure that these batteries provide greater possibilities and innovations for the future of electric vehicles.
