Re: HCHII Observations / Future Upgrade Options?
It's highly possible that down the road some we'll be able to upgrade to Lithium Ion battery packs. Maybe with a much higher battery pack capacity, too. Maybe even plug-in recharge capabilities. This will be good.
But, the electric motor is just not powerful enough to propel the HCH except for very short distances. Also, it's very difficult (if not impossible) to use the IMA alone from an absolute stop to move the car. However, I CAN easily get into IMA-only mode at 1100 RPM at low speeds (10-20MPH), and occasionally at other speeds. I can only sustain this IMA-only mode for a short while though. This is where tweaking the programming to go "all-IMA and stay there longer" COULD make a difference if we had much bigger battery capacity.
The Prius is targeted much more for the PHEV projects because:
(1) much more powerful electric motor,
(2) much more potential cargo area to put the (currently) rather large contraptions, and
(3) economics - many more Pruis' sold=worthwhile to make/market PHEV kits.
