Hey there, we are creating a hybrid system on a prebuilt UGV (unmanned ground vehicle) for our senior design project and are looking for some technical advice. We are all mechanical engineers so our electrical engineering knowledge is lacking so we are looking for some help.
Here is the setup:
-Two 36V batteries running off 3 12V Lifeline batteries connected in series.
Here is the goal:
-Recharge the three batteries using a small gasoline engine (3-6 HP basic engine). Have the system be fully automated and have the engine turn off and on via an electric start whenever the batteries run low on juice.
-The Issue:
What is the best way to go about getting a 36V charge from the motor?
The original idea was to use a basic 12V alternator and alter the internal regulator to output 36V. However, we are not sure how easy this is or if it is even possible.
Then we started to brainstorm about possibly charging in parallel and keep the alternator at 12V. However since the batteries have to output 36V, we don't think it will work to charge in parallel and output in series.
So now we are in a bind on how we should go about charging these 3 12V batteries. Any suggestions?
Also the electric start for the engine runs on 12V so somehow we are going to have to get 12V from the battery bank. Which seems like it won't work if they are all connected in series.
Any help would be very appreciated.
Thanks, UGVteam
