The Tesla Roadster uses a special cooling system for its battery pack 🚀. This system is called a liquid-cooled design, which means it uses a liquid to keep the batteries at a safe temperature. The liquid is a mix of water and ethylene glycol, which is similar to antifreeze 🧊. This mixture helps prevent the batteries from getting too hot or too cold, which can damage them.
The cooling system works by circulating this liquid through tubes in the battery pack, kind of like how blood flows through veins in our bodies 💉. This helps keep all the batteries at about the same temperature, which is important for making sure they work well and last a long time. In fact, the Tesla Roadster’s cooling system is so good that it can keep the temperature difference between different parts of the battery pack within just a couple of degrees Celsius ❄️.
The Tesla Roadster’s battery pack is made up of about 6,831 small lithium-ion batteries, which are similar to those used in laptops 📊. These batteries are arranged in a special way to help them stay cool and work efficiently. After driving 100,000 miles, the battery pack can still hold about 80% to 85% of its original power, which is really impressive 🚗. This shows how well the cooling system works to protect the batteries and keep them running smoothly over time.
