Questions to inspire discussion
-
What improvements have been made to the Tesla Cybertruck's battery pack?
—The second generation 4680 battery cells and structural pack have improved since Generation 1, leading to increased range and mass reduction.
-
What is the energy density of the standard range all-wheel drive mono wide battery pack in the first generation structural battery pack?
—The energy density is estimated to be around 158 wat hours per kilogram, which is 10% less than the non-structural battery pack versions found in other Tesla vehicles.
-
How does the energy density of the new 4680 battery cells compare to the 2170 cells in the Cybertruck?
—The 4680 battery cells have greater cell level energy density than the 2170 cells, but the pack level energy density is lower, potentially due to the implementation of the structural battery pack.
-
What is the potential for further improvement in the Cybertruck's battery pack design?
—Tesla is working on improving the structural battery pack design and increasing the energy density of their 4680 battery cells to potentially achieve longer range Cybertrucks.
-
What is the charging capability of the Cybertruck at a Tesla V4 supercharger?
—The Cybertruck can charge at up to 350 KW at a Tesla V4 supercharger and is the first Tesla with an 800 volt architecture for fast charging.
Key Insights
- 🚚 The Tesla Cybertruck has a second generation version of the structural battery pack and 4680 batteries, promising an improvement in energy density.
- 🔋 The new Cyber cells used in the Cyber truck are 10% more energy dense than the previous first generation.
- 🔋 The 4680 battery cells have greater energy density than the 2170 cells, yet the Cybertruck's pack level energy density is still lower than the Model Y's.
- 🔋 The previously reported 123 kWh hour number for the Cybertruck's battery pack seems to be confirmed by the EPA documents.
- ⚡ The Cybertruck is the first Tesla vehicle to have an 800 volt architecture, allowing for very quick charging.
- 🔋 The Tesla Cybertruck can charge at a 400 volt charger without the need for a costly booster, making it more convenient for users.
- 🔌 The GMC Hummer's 800 volt system allows for 350 KW Chargers to add 100 Mil in 10 minutes, while other manufacturers like lucid and Porsche have less effective solutions for accommodating both 400 volt and 800 volt charging.
- 🔌 The absence of a costly or lossy booster required for boosting the voltage from 400 to 800 volts indicates a significant reduction in energy loss during charging.
