![]() And, of course, various kinds of batteries age very differently in terms of cycle life and calendar life. Another consideration is that environmental conditions such as temperature and humidity affect each aging mechanism in its own way. In reality they are always operating together, and depending on the type of application and usage pattern one may become more important than the other. We tend to look at two kinds of aging: aging from use, called "cycle life," and aging with time, known as "calendar life." These two different aging mechanisms can be thought of as separate, overlapping forces. Batteries age with use, and they age with time, even if not used. The bottom line is that all batteries age, and they lose capacity as they do. Yet there is still a tradeoff between energy and life, even within the family of Li-ion.īack pack: The battery is carried in the safest and strongest part of the vehicle Li-ion chemistries have achieved better combinations of these parameters than anything that has come before. One of the most difficult challenges in battery design is increasing energy density while also maximizing battery life span. These Li-ion batteries are a whole lot better than Nickel-Metal Hydride (NiMH) cells and lead acid cells found in EVs of yore, but they too have their limitations. Though market forces continue to drive improvements in batteries, the Li-ion battery system in the Tesla Roadster represents the very best of today's commercially available battery technology. Batteries are not perfect – no doubt about it. To achieve this kind of performance, we were meticulous about our battery technology selection. Nestled securely in the back of the Tesla Roadster, the battery system is the secret behind our four second 0-60 mph acceleration and phenomenal driving range. ![]() It's roughly the size of a storage trunk and weighs about 900 pounds. Our battery system – or Energy Storage System, as we like to call it – is comprised of 6,831 individual Li-ion cells. But here are a few things about our batteries you might not have heard. By now most people know that the Tesla Roadster is powered by Lithium ion (Li-ion) batteries. ![]()
