From this plot we can clearly see as power increases the optimal voltage also increases. This optimal voltage range lies in our battery bus range and as such should be relatively optimized to minimize motor controller power losses.
From here we must define the max average temperature and the required flow requirements. This is governed approximately by the following equation.
