Where's the energy coming from?

    I have noted that the windows go up very slowly in the Ig-on mode but they rise much faster in the Ready mode. Can I assume that in the first mode the energy is coming from the auxiliary battery and in the second it's coming from the main battery? I suspect that my auxiliary battery is weak and this could be evidence to use for arguing with the dealer. :wink:

    Ignition on aux battery voltage is probably in the order of 12.4-12.7 volts and in the Ready position the voltage is in the order of 13.8-14.2 volts as such the electric window motor runs about 15-20% faster. The battery is charged from the Inverter/Converter under the hood. Inverter converts A/C to D/C and the converter drops it from 200-500 volts depending on generator (MG1) and or vehicle speed, to about 14 volts to charge the aux battery.

    I have a question: How much energy is captured during Regenerative Braking? Like 20%?

    I've heard more like 30-34% of the kinetic energy is converted back to electrical current but there are real experts on PriusChat and maybe the moderators will delete this in favor of a more definitive answer and I won't be embarassed in perpetuity when they supply the real answer. But until then... :oops:

    I've heard upwards of 60 amps max regen. Not able to confirm it but have see it mentioned several times. Might be less or more on the 2k4 but the infromation I have is on the Classic.
