I have project to design a tool to measure DC energy meter foe electric vehicle and pv. Please tell me which IC and microcontroller I should use. And If you have any references for this project, please share.
It's rather simple: About any microcontroller can do.
* measure average voltage
* measure average current
* multiply both to get power
* add up power in equal steps of time to get energy.
What will be your Max DC current ? 10A, 20A, 30A ? If withing 30A then use ACS712 sensor for current sensing. Measure voltage and current once a second. Do the maths to get power in watts/sec. If needed convert it to Kwh.

I don't know with for sure because this is my first time designing a energy meter. It will be used for measuring electric vehicle and pv, do you have any suggestion what will be the max DC current?
