Abstract: State-of-charge (SOC) estimation of lithium-ion (Li-ion) batteries with good accuracy is of critical importance for battery management systems. For the model-based methods, the electrochem-ical model has been widely used due to its accuracy and ability to describe the internal behaviors of the battery.

$begingroup$ It might make more sense if designing to use a higher voltage, lower current supply. 24V is half the current, so those high-current traces could be less than half as wide at twice the voltage. Then two battery packs can be used, extending run-time to slightly better than 2x and improving overall efficiency.
