This thread is dedicated to experimenting with the SG 3 battery 24 volt configuration as presented by Dr. Peter Lindemann in diagram from another ESF thread. The attached diagram depicts the SG wiring configuration for this modification. The results as depicted are preliminary and are run on a plain-Jane SG system that is not tweaked for high performance.
This configuration was assembled and then tested with two different wheel assemblies (high and low friction) with different free spin times. The run data can be viewed in the attached .pdf file. This data is compared to prior runs that were completed with the standard SG 12 volt battery configuration at similar gaps and trigger resistances.
Review of the run data immediately demonstrates that the SG Mod PL (3 battery 24 volt) configuration has very different operational characteristics, in that the amperage data is significantly lower for both Primary and Charge amp values for both wheel assemblies. At first glance the Load Discharge watt hrs and Charge watt hrs appear to yield a COP of about 2.0, however this is deceiving in that the Charge battery is also receiving input from the Primary batteries. In reality the COP for this configuration should be based on the Primary power and not the Charge power – so the value here is 0.59 versus about 0.44 for the SG standard.
The performance of this configuration is significantly better that the standard SG setup and improves the charging rate to the Charge battery. This can be observed by noting the higher Charge battery voltage values during operation for the given gap and wheel configuration. Looking at tests 1 and 2 it is very apparent that for a given Primary power input the resultant Discharge power is approximately improved by about 45 percent.
More testing is required to confirm the above; however the preliminary tests appear to be very promising for further research of the Peter Lindemann 3 battery configuration.
More testing of this type is expected to be completed over the next week or so with the results posted upon completion. Please note that any errors in calculation or assumptions are strictly attributable to the author of this thread.
As always, questions and comments relevant to this thread are always welcome.
Thank you Dr. Peter for your excellent input!
