Re: killed gs450h inverter

Looks like you connected the HV wrong, it is before the booster and you have fried the 12V DCDC and possibly done more damage. You need to connect to the Inverter bus and not the Battery bus.

Re: Gen 3 Prius Transaxle P410 Makes Clunky Noise.

Did today's testing unequivocally show that the inverter temperature is signed 8 bit? If so then the GS450 tmphs/temp_inv_water still needs fixing temp_inv_water=int8_t(mth_data[42]); Working through them all one by one, yes the temps are most likely reported in int8_t as IS300H threw problems belo...

Re: Gen 3 Prius Transaxle P410 Makes Clunky Noise.

Long and short of it is, The zombie was thinking the inverter was reporting a really high temp so it was cutting throttle.

Re: Gen 3 Prius Transaxle P410 Makes Clunky Noise.

Also MG1 has no way of transferring any torque, due to not having an engine in it.

Also this means no oil pump working, so locking the PSD is the only way to get the oil pump working and MG1 capable of providing torque.

Re: Gen 3 Prius Transaxle P410 Makes Clunky Noise.

So you are saying that spinning it by hand you feel no weird resistance or noise? It is very possible your power supply is limiting or you getting a big drop across your tiny test wires into the inverter causing it to drop in and out. Is there oil inside you gearbox? As it could be MG1 and MG2 fight...

Re: 1984 Voltswagen Rabbit Prius Gen 3 ZOMBIE

you need to set UDCsw to 0 to bypass contactors. Please post your full settng download.

You need ignition power this should be the pin 15 you mention, and then also a start signal pin 52 as per diagram linked.

Re: LIN based CCS

Tesla does this for AC:

- Digital comms via Single Wire CAN on CP, if no response time out and go to PWM -12V +12V like other charger.

You could just do this with SWcan and even just run chademo protocol ;)

Re: Battery packs with 3p

Why 3p, you are quite lost. How many cells are in parallel has nothing to do with its performance.

You need to find the continuous and peak rating of the packs. The cells used and in which configuration has no direct link to this.
