GA-based approach to optimize an equivalent electric circuit model of a Li-ion battery-pack

作者：

Highlights：

• Time and frequency domain tests are performed for a commercial Li-ion battery pack.

• Different RC networks have been used to modeling the battery pack.

• A Genetic Algorithm is applied to optimize the parameters of the battery model.

• A hardware-in-the-loop simulations platform reproduces real driving cycles of an electric vehicle.

• A low-order model reproduces with high accuracy the behavior of the battery pack.
