Detailed Description

A battery abstraction.

The default battery model is ideal: It just takes the initial voltage value as its constant voltage value. This behavior can be changed by specifying a custom update function.

The battery handles a list of consumers. It updates itself after each simulation iteration. The update function takes the power loads for each consumer and current voltage value as inputs and returns a new voltage value.
