Then, the actual battery capacity prediction value was used to replace the battery rated capacity in the traditional ampere-hour integral method, and the value was brought into the improved ampere-hour integral method for SOC estimation.
Battery Management System Algorithms: There are a number of fundamental functions that the Battery Management System needs to control and report with the help of algorithms. These include: Therefore there are a number of battery management system algorithms required to estimate, compare, publish and control.
The battery capacity, which changes dynamically with environmental factors, is used as a constant in the traditional ampere-hour integral method, and that will also cause some errors.
Furthermore, we aim to test the ability of the algorithm to predict battery capacity taking into account the influence of other external factors such as temperature, depth of discharge, cell balancing etc, this can be achieved by exploiting battery aging datasets containing such factors.
