How to use LM317T? Answered
I have a robot on wheels that uses 7.2v battery. The battery runs it for good amount of time it is a 2000mah nimh vex battery. I want to supplement and charge it during peak hours. I bought 4 solar panel that can produce 2 V near my window and 3 volts outside. They produce 200mah at full sun. I want to series the solar panel up and have voltage regulator that can regulate it. I was told that the current also needs to be constant and so I ordered a LM317T.
Here is the datesheet of lm317t
How does the lm317t react when my solar panel hit shade and current goes under 200mah. What voltage should I put on my voltage regulator that I will connect to LM317T. Should I make it 10 V or 9 V?
I really am new to this and want to use solar energy to charge my battery while it is connected to my robot in parallel. What current should be held constant to charge 7.2v 2000mah nimh?
