Can BMS algorithm improve battery efficiency?

In this paper we proposed a BMS algorithm that considers battery efficiency. The algorithm was applied to an ESS to improve the battery safety and performance. The algorithm proposed in this paper was divided into three parts. First, the efficiency of the battery was used to estimate the state of the battery.

What is a battery management system (BMS)?

The purpose of a battery management system (BMS) is to manage the battery [ 14, 15 ]. To improve the reliability and safety of the battery [ 16, 17 ], many BMS functions are being developed [ 18 ]. The functions of BMS can be classified as real-time monitoring, calculation and prediction, protection, and optimization.

Can BMS algorithm be used to verify battery efficiency of ESS?

A 3-kW ESS was implemented to verify the BMS algorithm of the ESS considering the battery efficiency. The BMS algorithm proposed in this paper was applied to the ESS and the battery efficiency was tested during the charge-discharge process by charging several battery modules.

Can a BMS algorithm predict the correct battery state?

The paper predicted the correct battery state through BMS and diagnosed the fault using the proposed method during the charge-discharge process to propose a BMS algorithm for an ESS that uses a large battery capacity. 4.

How does a BMS algorithm work?

The proposed BMS algorithm can sense the battery voltage, current, and temperature and calculate its efficiency. When the efficiency of a battery is calculated, its charge-discharge current is measured to determine whether the ESS is in the charge-discharge state.

How to apply BMS algorithm to ESS?

To apply the BMS algorithm to the ESS, the experiment was conducted by deriving the internal resistance of the battery from its efficiency. Moreover, the increase in battery state accuracy was verified through experiments by applying the battery efficiency to the SoC with the OCV and CCM and the SoH considering the charging time.
