Bay Area researchers from Stanford have discovered that electric vehicle (EV) batteries can endure significantly longer than initial projections. Utilizing testing methods that simulate real-world driving conditions, the study, led by Professor William Chueh, revealed that the average lifespan of EV batteries could be around 40% greater than earlier estimates. The researchers observed that the batteries responded dynamically to charging cycles and environmental variables, highlighting the importance of realistic testing parameters in understanding battery aging.
They say the data suggests average EV battery life may be roughly 40% longer than estimated. It is a result that's the opposite of what the team theorized.
So, here we have a room full of cyclers and environmental chambers to cycles, meaning charging and discharging batteries to study how they age.
More realistic representative of real driving. And, you can see both the voltage response of the battery and the current are very dynamic.
Can I give you a jolt? Chueh said, smiling as he pressed the accelerator of his Tesla.
