Hi all, I just searched for a thread for a conversion from the 2.2 kWh battery of the first PiP to 4.4 kWh from Prime. Will that be possible? I suppose that it is necessary a charger and some wiring, I don't know about the ECU's but still it would be interesting if someone made such a modification.
anything is possible, but not everything is worthwhile. the modifications would be so major, that it would have to be a labor of love. prime are so cheap these days, there isn't enough love in the world
Step 1. dimensions, could it fit? step 2 specifications Voltage # of cells, BMS arrangements Step 3 connectivity, what connectors are used throughout the battery system? occassionally you luck out like in a leaf where you can transfer new cells into an old battery other times not so much. You start, I’ll wait for your progress answering these problems with solutions
I guess so, Rmay635703 , maybe as a project, it would be interesting to see the outcome of this. But you are correct, it involves more that just "few" modifications indeed. I'll stick with the 2.2 battery for now. I was interested because i found such a battery quite cheap, but a lot of headache to modify. All i wanted was a few more miles on the electric side than the actual, after a full charge.
The Prime's battery is 8.78 kWh, not 4.4. I'm pretty sure the voltage is higher, too. I know it's much higher than a regular Prius. I've done no research, so this is off the top of my head, but I think you'd need: A bigger charger since the Prime charges with more current than the PiP. A bigger inverter for the same reason. Bigger wires between the inverter & battery to handle the increased current. New ECUs from a Prime to control the system. Possibly stronger rear suspension due to the increased weight.
