From what I have read both the voltage and current must be monitored and controlled to safely and efficiently charge Li-ion batteries. There are several different chemistries in the lithium battery "family" and each has slightly different requirements.
The first thing I would do with your program is get rid of the dynamic data types. Coming from the signal simulator the dynamic data type contains a waveform with 100 samples (all having the same value). In the false case of the small case structure the signal is compared to a scalar constant. The result is a dynamic data type containing a boolean. In the true case the signal passes through. Now, the selector inputs of the two case structures (you only need one, by the way) are expecting booleans but get dynamic data which MAY contain either a boolean or a waveform. Note the coercion dots. LabVIEW converts that waveform to a boolean --- BUT no one outside NI R&D knows exactly how that conversionis done. Does it take the first sample, the last sample, or some combination and compare to zero to get a boolean? Or does it use the t0? Or something else? As the programmer, you need to know what your program is going to do and this does not allow it.
The peak detector does not work because you give it only one data point. Where is the peak in an array of one element? And remember that if that first case structure used the false case, the data into the time averaging VI contains only a boolean.
