Hi!
I'm very new to LabView and currently trying to make an algorithm determining state of charge in a battery for one of my classes. Unfortunately I've stumbled upon some obstacles in making the LabView code. For the first time I can't find the solutions anywhere, so you guys are my last resort, hopefully you can help me:(. Here are the things I don't really know how to solve;
1. How to get a percentage value out of voltage measurement where 13.5V equals to 100% and 10.5 equals 0% where there is a linear correlation between these "points". Then depending on what voltage reading I get make it the percentage value.
2. Measuring current multiple times and how to sample these readings and calculate the average value.
3. How to make an equation where I have to integrate the average current over time in the equation.
These points should be connected to get a value of the battery state of charge. All the help I can get is very very welcome! |

Hello...as per the response from LabView website forum, Integration is really nothing more than adding all of your measurements. The simple method would be to use the Integrate PtByPt VI. But I would probably go the route of using a shift register to keep the count of Coulombs. You just take your current reading (Amps), multiply by the number of seconds between your samples (Amps = Coulombs/sec, therefore A*s = # of Coulombs), and then add to the count in the shift register. |

You'll need to contact National Instruments, the maker of LabView. We do not provide support for LabView.
