Using the load profile to predict battery performance and lifespan
Using batteries to replace diesel engines or augment the performance of diesel generators is becoming a marine power plant requirement. This paper will explain how to decide on the type and size of a battery best suited for the application at hand. The basis of this decision involves determining and reviewing the load profile of the application. With this load profile, mathematical models of the battery can be used to dimension the battery. With the profile and model, a solution that fits the commercial framework can be determined.
