Hi!
I'm looking at the EVM schematic and I'm struggling to define what happens in the circuit when:
- the Battery is sourcing the energy (discharge state) at first, both DSG and CHG FETs are turned on.
- then the load acts as energy source - let's say It's a motor with regenerative braking.
- plus everything can happen in short/long uncontrollable peaks.
Does this smart battery act like a normal battery or some sort of protection kicks in? Can someone explain what happens with the extra energy?
From the notes i see that if DSG current is small enough the DSG fet is turned off, so the current could only flow by the body diode. But then probably CHG FET would be off so battery could not charge,
