Stumbled upon a great image at the back of the F1 2014 regulations that I find rather interesting.
Details the energy flows with the 2014 power units really well.

A few interesting things stand out:
The ES can store 4MJ of energy, but only 2MJ per lap can be harvested from the MGUK (i.e. the KERS we have now connected to the rear axle). I've no idea if the energy harvested from the turbo (MGUH) can fill the 2MJ gap?
Restrictions on the energy only apply in and out of the ES to the MGUK. What can be harvested isn't limited. This means 'things' can be powered directly by the MGUK or MGUH. I've no idea what this would mean as I don't know what ancillary devices could be powered by the fluctuating power output from the MGU's, but its interesting.
And the unlimited link between the MGUK and MGUH, and its bidirectionality, is very interesting. This meas the turbo can power the KERS, and the KERS can power the turbo, directly and without limits. Could we see the KERS being used to keep the turbo spinning while the driver is off throttle and braking, keeping the engine in the sweet spot for torque delivery on corner exit? There is an unlimited link between the ES and the turbo that could be used for anti-lag, but this would eat into the 4MJ limit in the battery. Much better to use spare MGUK energy to power anti-lag.
All very interesting.
For reference, the 2013 KERS regulations limit the cars to 400KJ of energy harvester and deployed per lap, through a motor with a power output of 60KW. In simple terms, 7 seconds of 80BHP extra power. In 2014 it will be 35 seconds of 160BHP of extra power. The requirement for the driver to be in control of the energy discharge through the KERS system is removed for 2014 so the flow of energy can be completely automated, completely manual, or the more likely combination of a mix of both.
