Modify a Type I Prius
I am thinking of getting a Type 1 ,2001 Prius and was wondering about the pack voltage. Does any one know the real running voltage of battery pack? Is it a 296 volt run and 273.6 volt nominal voltage. I want to use a switching power supply for radio gear off of the high voltage side. The Type III pack is 201.6 volt and consist of 28 modules of 7.2 volts for the 201.6 volts nominal voltage. I purchased a number of Prius modules and all or mostly all were dead "Dead" so I am sure the whole pack must be replaced and if I have to replace it, will it get me ten years more. Also thinking of adding an outlet on Type I to allow charging via J-1772-2007 at local rest stop here in Massachusetts. In Current EVents magazine there is an ad for Enginer kits to allow 120 vol to 48 volt Lithium conversion to pack voltage but Type I is higher pack voltage than Type II or Type III. Their MSRP is $3495.00 but again it is for later versions. So again does any one still have and drive a Type I Prius?
Charging at 240 volt and a full wave rectifier will give about 312 volt charge on capacitors so maybe it can charge Type I pack also? Just have to limit current to an amp or two.

depends which type 1 you are referring to :)
NHW10 (1996 - 2001) had a nominal voltage of 288V, and a target hold voltage of 330V.
That's the one I own, and am doing a Lithium conversion now (using 100 x GBS 20Ah cells).
NHW11 (2001 - 2003) had a nominal voltage of 273V, not sure what the target voltage was
In both cases, the usable capacity of the original battery is just shy of 1kwh
The Enginer kits basically a 48v - 220vac inverter, and just tap the internal DC-bus (which was designed to float at 330vdc)
Their output voltage can be adjusted up to the battery voltage of the early Prius batteries.
I would just get their inverter, and build the 48v battery and charger yourself
