Default What is the amperage of the batteries in the new 2009 Prius?
Just want to know.















Any model.















I know the voltage is like 220v or 260v DC.

They are boosted to 500 volts compared to the 273.6 of second generation.

Ohms's Law: I = W / V (where I = amperage, W = watts, V = volts)

Hi,































the new 2010 Prius nickel metal hydride (NiMH) hybrid battery has a maximum voltage of 650 volts DC dialed up from the initial 202 volts through the improved Hybrid Synergy Drive system.































Each of the 168 cells stores 1.2 volts at a capacity of 6.5 ampere hours.































Details of the 2010 Prius system can be found direct from Toyota here:































http://pressroom.toyota.com/pr/tms/t...Info_FINAL.pdf































By comparison, the last generation of the Prius in the US produced a maximum of 500 volts DC dialed up from the 202 stored volts. That would be the second generation for the US, which would be the 2004 to 2009 model years, not the new 2010 Prius that just arrived in the US in May.































The '04-'09 Prius NiMH had a max of about 80 amps.































Just FYI, all Toyota/Lexus hybrids have a 12 volt lead acid battery system that is independent of the NiMH system. The only exceptions are the Lexus models that actually have a second lead acid system to control additional suspension controls.
