When it hits 38%, motor shuts off and the batt drifts back down to 35%. They've sized the generator appropriately so its near impossible for the battery to drop much once the generator is on. Remember, no 120 mph, no towing.
But under continuous stress like hours (mabe pure indiference - Run at maximum speed on the highway; passing anyone on a regular road), the regenerative power would not count much. So, wouldn't it be more likely to rev up the gas engine to its maximum power (100hp), to cope with this situation - generate maximum electricity through the generator.
Also, the maximum power output of the car should be limited considering this aspect, considering one wouldn't want changes in the behaviour of the car(safety reasons).
The maximum power would be the maximum power the gas engine can deliver considering the most extreme case when the battery is depleted.
