The Tesla Roadster uses Lithium-Ion batteries 🚀, which are similar to those found in laptops. These batteries are made up of many small cells, called 18650 cells, and they are arranged in a special way to store a lot of energy. The original Roadster battery pack contains about 6,831 of these cells, and it can store about 53 kWh of usable energy, allowing the car to travel over 240 miles on a single charge 🚗.
The battery system is designed to keep all the cells at the same temperature, which helps the car go further and perform better. This is done with a cooling system that circulates fluid through the batteries, keeping them safe from extreme temperatures ❄️.
In recent developments, some companies have created new battery systems for the Roadster, like the one from EV Europe, which offers a battery module with a capacity of over 64 kWh and weighs less than the original 📈. This new system also allows for faster charging, making the Roadster more practical for daily use.
Overall, the Tesla Roadster’s battery is designed to be efficient and long-lasting, with studies showing that it can retain a significant amount of its capacity even after many miles of driving 📊.
