Is it not beneficial to do this on an insight?
1) Because the tiny electric motor on an Insight isn't up to the task of full propulsion, so using it to supplement the gas engine is the only practical solution IF that's what you really want to do.
Mudder's example in this post:
2kW (2.68hp, about 20-25% of the energy for straight and level typical highway cruise) for 4 hours = 8kWh of energy.
The Insight battery contains 0.936kWh of energy TOTAL. that means you need a battery with 8.5X the capacity of the stock Insight battery. If you want it to last, you have to reduce the DoD to something along the traditional 80/20% SoC limits, so now your capacity is 13.3kWh or 14X the capacity of the stock Insight battery.
Additionally, while I regard the IMA motor as robust, low utilization for long periods of time is exactly NOT what it was designed for.
I doubt you're going to get anywhere near that capacity with your bike batteries.
