90% Max Charge Limit for Daily Drivingįirst, you only have a 90% max charge limit for daily driving with an NCA battery because that can lead to quicker and more severe battery degradation. Things to Consider about NCA BatteriesĬurrently, the Model S, Model X, and dual motor variants of Model 3 and Model Y are all powered by NCA batteries, which leads to some things to consider when owning any of these vehicles. This battery chemistry produces some challenges to Tesla, from the ethical dilemma of mining for cobalt to the high cost of nickel which recently spiked to 100,000 per metric ton and ironically made the value of an actual nickel coin worth more than a dime.
T he 2170 BatteryĪ few years later, in 2017, with the launch of the Model 3, Tesla and Panasonic developed a new and improved type of battery cell called “the 2170” which is 21 millimeters by 70 millimeters and can store a lot more energy than its predecessor.Īccording to Elon Musk at the time, it was the highest energy density cell in the world and also the cheapest. The 2170 cell is around 50% larger by volume than the 18650, but it can deliver almost double the current. The 2170 battery cell is currently what’s used in all of the dual-motor variants of the Model 3 and Model Y.īoth of these battery cells are considered NCA batteries. The Model S and Model X are still equipped with these battery cells to this day, with a single vehicle battery pack containing thousands of these cells. Nearly a decade ago, Tesla began utilizing battery cells called “the 18650” which Panasonic manufactured for the Model S and Model X. The battery name comes from the dimensions of the cells, which are 18 millimeters in diameter and 65 millimeters in length and the overall size is slightly larger than your standard AA battery. Let’s take a look at Tesla’s first battery option: the Nickel Cobalt Aluminum (NCA). What are the Benefits of LFP Compared to NCA?.
