lolder Report post Posted September 13, 2013 (edited) Very cool! So... 280 volts x 20 amps = 5600 watts = 5.6 kW = 7.51 hp. This makes sense that the first line on the Empower screen would be about 7.5 hp considering that when the ICE is running at that line it typically shows about 21-23 hp with about 16-18 amps flowing into the battery. When idling with the ICE on I've determined that 14-15 hp from the ICE gets about 16-18 amps of charge flowing into the battery. So if we take away the 14-15 horsepower for the generator we're left with about 7.5 horsepower left to power the car. Very cool!! Thank you for the reminder of how it works. The max charging I've observed is just over 40 amps. The max discharging I've observed is just over 50 amps.The HVB can peak for 1 second at over 120 amps discharge ( 34 kw at 270 V. ) and about 90 ( 25 kw ) charge in the Gen I FFH. See table 2 here: http://avt.inl.gov/pdf/hev/batteryfusion4757.pdf.50 amps is reasonable to see in normal driving.I would expect the LiIon of the Gen II FFH to be more powerful.
