When comparing Tesla charging data, an interesting pattern appears. Under similar charging currents, NCM batteries heat up more, while LFP batteries stay noticeably cooler. At first glance, this looks counter-intuitive. LFP chemistry is well known for being more thermally robust.

These days, because of recent Tesla issues, many people say things like “using cylindrical cells was a mistake” or “Tesla had no choice but to use them.” That might have been true long ago when prismatic and pouch cells were not widely available. But even today, choosing a cell type is far from a simple decision. In battery pack design, there is always a trade-off. Safety, energy density, manufacturing complexity, and cost are all interconnected, and the outcome depends on wh

Everyone drives differently. Some people drive long distances every day, while others use their cars only occasionally. Even users who haven’t driven at all for a whole week may wonder if they still need to do a full charge. So why does Tesla give the same “once a week full charge” advice to everyone? The main reason is simplicity. From the manufacturer’s point of view, it’s difficult to explain charging intervals based on each user’s driving distance or energy use. A simple
