I thought it was for safety. The HV relays turn off, so you need to bypass them or activate them independently, correct? I also thought the Prius regulates the rate of charge by dissipating to the engine spin and/or MG2 as much as needed to keep amps within Toyota's spec. The OEM pack is about 0.5 kWh, and I kind of use it to deplete my kit a little more.
Mostly I return home with plenty of Enginer juice left. Probably my voltage cutoff is too low. I usually set the parking brake and leave the kit on while plugging in, cleaning the car interior, kicking mudflap stalactites, and brushing away snow. While driving I would like to find some other way to take advantage of the 50V DC from the kit directly without passing it through the converter, such as heated seats and/or powering an electric defroster directly off the Enginer pack. Maybe four cheap 12V defroster fans "in series", but probably there is no elegant way to mount them.
