One of the most common myths about electric cars is the belief that battery capacity rapidly declines, especially during frequent rapid acceleration or braking.
Recent research conducted by Stanford University and the SLAC National Accelerator Laboratory in the US debunks this theory, pointing to something completely different. This means that owners of zero-emission cars can breathe a sigh of relief, and manufacturers can update their charging systems.
The groundbreaking discovery by US scientists was preceded by a two-year period of battery testing in various situations. While previously the durability of lithium-ion batteries has been tested mainly in controlled laboratory conditions, which do not reflect actual vehicle operating conditions, American experts have created a special scale for battery discharge profiles.
Tests on 92 batteries in various driving situations indicate significantly higher battery performance than expected.
Innovative discovery
Even more surprising are the findings regarding rapid acceleration or braking, which are commonly believed to lead to faster battery wear. However, what turned out to be much more harmful was... battery inactivity. Therefore, refraining from driving can contribute to its faster degradation.
The durability of EV batteries is the result of advanced technological solutions, such as battery management systems (BMS) that monitor temperature, voltage, and state of charge to prevent overloading and overheating; liquid cooling that minimizes the risk of cell degradation resulting from high temperatures; and continuous software updates that optimize battery operation and improve its performance over time.
How to care for an EV battery?
While every battery depletes over time, the rate of this process for EV batteries is much slower than expected. Manufacturers such as Tesla, Nissan, and BMW are introducing innovations that further extend battery life. An example would be the use of cell chemistry optimized for durability instead of maximum energy density.
At the same time, it is EV users who have the greatest impact on battery life. One practice that helps maintain batteries in good condition for a long time is to avoid full discharge and recharging. It is best not to discharge below 20% or charge above 80%.
Another way to care for the battery is to avoid exposing a zero-emission car to high or low temperatures. Therefore, in the summer, park in shaded, cool places, and in the garage in the winter.
Using eco modes also affects battery life. Built-in systems enable efficient energy consumption, which translates into reduced battery load.
The Future of Batteries in EVs
Work on new technologies, such as solid-state batteries and lithium-sulfur cells, heralds another breakthrough in electromobility. These innovations are expected to further extend battery life and increase their energy density, while simultaneously reducing production costs.
FAQ
🔋 Do batteries in electric cars wear out quickly?
No. Recent research shows that EV batteries last much longer than previously thought – even with heavy use.
⚡ Does frequent acceleration and braking damage the battery?
Contrary to popular belief – no. Studies have shown that inactivity has a greater impact on battery degradation than vigorous driving.
🌡️ How does temperature affect battery life?
Extreme temperatures (both high and low) can accelerate battery degradation. That's why it's a good idea to park in the shade in the summer and in a garage in the winter.
🔄 What's the best way to charge an EV battery?
It's recommended to keep the charge level between 20% and 80%. Avoid full discharge and charging to 100% unless necessary.
🧠 What is a BMS?
A BMS (Battery Management System) is a battery management system that monitors the battery's condition, temperature, and voltage, protecting it from overheating and overloading.
🚗 Does eco mode really help?
Yes. Eco modes limit power consumption, which reduces battery strain and extends battery life.
🔬 What are the future battery technologies?
Work is currently underway on solid-state batteries and lithium-sulfur cells, which are expected to increase battery durability, capacity, and safety.
