BTW, i was doing some math.
For 10kW of power at 100 Volts you need 100 Amps.
Which means if you will have 100Ah/100V battery, you can deliver that power for one hour.
For one minute at 10kW you consume 1.66 Ah, so if the capacity of the pack is lets say 5Ah at 100A draw, you can deliver it for 3 minutes.
Which is clearly not the way how the system works - the 2013 model allows boost for 10 seconds only.
It is clear why, 100A draw is 20C draw for 5Ah battery, which is high for NiMH and mild-to-high for LiOn chemistry.
If the battery would be abused that way, it would not last more then hundreds of cycles and 1-3 years.
So, my point is, the number of bars you see on the dash have nothing to do with the actual state of charge of the pack.
The electronics probably use roughly 20% of the capacity and only when the pack is in optimal condition, avoiding undercharging, overcharging, long term amp draw and temperature rise from the draw.
There is probably space to hack the electronics to behave differently, because this is too "conservative".
