Battery Modeling

摘要

1. Estimation of battery performance. Given an already constructed battery, the problem is to estimate how that battery will perform under specific conditions of interest to the user of the battery. This problem is typically addressed by testing batteries under the specific conditions of interest and using a model to represent the test results. Approaches for representing test results range from simple statistical models to neural nets to complex, physics-based models. Basing the model on test data becomes problematical when testing becomes impractical (such as a 10-20 year life test). Real-time estimation of battery performance, an important problem in automotive applications, falls into this area.
