A battery management system (BMS) is a critical component of every electrical system containing batteries, which are vulnerable to various conditions of operating conditions. The purpose of BMS is to guarantee safe and reliable battery operation. To maintain the safety and reliability of the battery, state monitoring and evaluation, charge control, and cell balancing are functionalities that have been implemented in BMS. As an electrochemical product, a battery acts differently under different operational and environmental conditions. The uncertainty of a battery’s performance poses a challenge to the implementation of these functions. This paper addresses the hardware implementation of a BMS by state evaluation of a Li-ion 48V battery using 18650 cells, including state of charge and state of life which is a critical task for a BMS. Through reviewing the latest methodologies for the state evaluation of batteries, the future challenges for BMS are presented and possible solutions are proposed as well.
