FIGURE K-2 KROMREY CONVERTER SETUP 2
PICTURE C-l.l shows the second test setup. On the left side is the Kromrev Converter, powered by an electric motor (center). Battery #2 is the battery in the front (center right) and battery is the one behind it. The voltmeter shows the voltage of battery #2. The 12 V light bulb is on the table in front of battery #2.
Because the Kromrey Converter turned too slow on one 12 V battery, we decided to drive the Converter using 24 V via two 12 V batteries, connected in series. PICTURE C-1.2 shows this setup.
Next we wanted to find a correlation between the normal charging of battery #2 using a commercial battery charger^ and charging this same battery with the Kromrey Converter. We drained the battery #2 to 8 V, connected it to the Kromrey Converter, and after reaching 11.51 V, we measured the time it took to charge the battery from this voltage level of 11.51 V to 12.45 V. We reached -his voltage (12.45 V) after 11 minutes. The indicated current into the battery was 0.94 A.
We then repeated these steps using the commercial battery charger. Because we ran out of time after nearly 2 hours, we disconnected the battery from the charger. The battery voltage had reached 12.41 V. The measurement is depicted in FIGURE K-3.
