The attachment is not working again, so here another one, maybe this one will work. I change from PNG to JPG.

Hi everybody,
First thanks for all the comments, every thought is useful.
Reading your ideas, searching the internet, thinking about the current design make me realised that my actual concept may not be the best way to go for my application.
The thread starts while I was thinking to add a...
Hi, a few information's in regard to everyone post:
The recommended bulk charge rate is around 10% of the battery capacity of 100amps so around 10amps. I design the circuit to handle 15 amps, but I limit the current to not more than 10amp via the PWM.
The 0-3.3V in relation with the sense...
The File again, this time I think it will work, sorry for the previous mistake.
Bye

I tough I did post an attachment, I did attached a JPG of the driver circuit section with my original post. Maybe it did not work, I will repost it tomorrow, I am no longer at my office computer. I remember seeing a message indicating that the JPG was uploaded correctly, I do not know were it is...
Hi, For different reasons, I am designing a custom battery charger for an 12Vdc 100amps AGM battery. I use a PWM control circuit, but the driving Mosfet tend to heat a lot. The actual circuit simply switch the input DC source (solar panels) using a power mosfet directly in the battery trough...
