LiBSU - Redesigning the "Battery Support Unit" to Support Lithium

So, is the inverter enforcing limits based on HV readings or its own readings?
Would be fun if the inverter blindly trusts and use the HV readings

That's only for my Prius C tho, not sure a regular Prius behaves differently.

I also recall that you would like the LiBSU to work for any chemistry, while making it non user interactable. Any thoughts on the implementation yet?

 

There's a middleman in the story being left unnamed: in a gen 3 Prius, the BSU is really talking to the power management control ECU, under the dash. That ECU drives most 'macro' behaviors here being attributed to the inverter. Most of the comments above about what the inverter does or what the inverter cares about are really about the power management control ECU.

(In fact, the power management control ECU is really just talking to another ECU, the MG ECU that's inside the inverter enclosure. The MG ECU is what directly controls the inverter switching, and all the 'micro' details like synchronizing to the MG rotors' rotational position.)

 

Would be great if you can share any diagrams, or link us to posts about this in detail!

 

... one of the many diagrams in the New Car Features manual, which is the one to turn to for learning how the car works.
