Low-complexity online estimation for LiFePO4 battery state of charge in electric vehicles

This paper proposes a low-complexity online state of charge estimation method for LiFePO4 battery in electrical vehicles. The proposed method is able to achieve accurate state of charge with less computational efforts in comparison with the nonlinear Kalman filters, and also can provide state of health information for battery management system. According to the error …

New online discussion forum in the PhD network

We have launched a new forum in our PhD network to facilitate an easy and accessible way of sharing knowledge. Membership of the forum is required to post, but the discussions are public. Topics in the forum could be related to experimental best-practice, finding a reliable supplier and establishing collaboration on experimental techniques. Have a look at …
