Our Prius batteries if gen 2 upgraded are 21kw or around 28hp... Now I'm pushing nearly 31kw with additional packs so I should be around 42 hp.. Now we have the equivalent to 44Hp electrics correct? Without compromising the integrity of the system has anyone tried increasing our inverters capacity ? The electric side alone is worth 258 ftlbs of torque plus the gas side is in the 80ftlbs. If we could unlock some of this potential even with some kind of "oh shit" command. We could have some monster takeoff and early acceleration ! Just some ramblings opinions wanted. Have fun ! Eric
Well let's look at the problems: more power -> more current -> more wiring heat :: the main power cables from the traction battery to the inverter might need replacement inverter IGBT rating :: more power means more heat and the likely hood of failure MG1/MG2 stators -> more current :: leads to more heating and increased risk of stator failure I don't see trying to increase the electrical path power as being all that useful. Rather, you might look at the unpowered rear axle and see if it makes sense to find a differential rear end that fits and mount a motor on that differential with an independent, electrical power source. In effect, an all-wheel drive Prius. Bob Wilson
You sir have seriously rained on my parade....lol my Ev build I've constructed a 1000amp controller but everything is dc I'm going to buy a scrap controller and see what I come up with Btw my ev is called SOLFork It's a civic Del Sol with a 12" forklift motor the current (hehe) wait is on batteries Have fun !
