An arrangement provides simulation of important battery factors such as state of charge or state of health, and the estimates are provided to the human user in ways that permit the human user to make better use of the battery, for example in an electric car. The arrangement is made up in part of nodes, each individually simulated, and at least some of the nodes communicate with each other by means of values which within the domain of the simulator are understood as currents but which may have real-world significance for some value that is not a current at all. The currents are passed on a (simulated) analog bus. Some lines on the analog bus, while understood as “currents” in the domain of the simulator, are actually values that merely pass messages between modeling elements, the “current” values not necessarily representing any real-life measurable such as the aforementioned temperature value. |

1. A method at arriving at an estimate of a state of a battery having first and second terminals, the battery connected with a load through a current sensor having an output, the battery further having a temperature sensor having an output, the method carried out with respect to a plurality of modeling elements within a battery simulator, the method comprising the steps of:
receiving the output of the current sensor at at least one of the modeling elements within the battery simulator; receiving the output of the temperature sensor at at least one of the modeling elements within the battery simulator; at a first one of the modeling elements within the battery simulator, sourcing a second current having a current value; at a second one of the modeling elements within the battery simulator, sinking the second current; within the battery simulator, arriving at the estimate of the state of the battery based upon at least the output of the current sensor, the output of the temperature sensor, and the value of the second current, and communicating the estimate of the state of the battery externally from the battery simulator. |
