Happy to agree.jadnashuanh wrote:Some people have unrealistic expectations about the i3. It's a great car for what it's designed for. Complaining about it's performance when used outside of those parameters is just misguided and misplaced.
If the engine runs at full speed, one could add over 7 KWh to the battery charge during a 20 minute stop. Does anyone with a REx want to try it?10.1. Exhaust-gas test mode
It is necessary to start the combustion engine for an exhaust-gas test in the BMW I01 with range extender. This is made possible by a certain operating sequence:
• Tailgate is open
• Switch on ignition and engage drive position "P" (without braking)
• Press and hold down the accelerator pedal within 60 seconds
• Press the brake three times within 20 seconds and hold
• Release the accelerator pedal and press the START-STOP button when the brake is actuated
• The combustion engine starts if the SOC of the high-voltage battery is less than 75 %.
As a Check Control message the status "Exhaust-gas test mode activated" is output when the combustion engine is running. The empty run point is automatically approached during the warm-up phase. Using the pedal sensor position two speed points of the combustion engine are selected for the measurement.
The "Exhaust-gas test" mode is automatically ended:
• after 20 minutes
• or at the start of the journey
• or by switching off the ignition.
Note that the output power of the ICE engine isn't equal to the electric output of the generator. Right under that diagram the document mentions that the 94% efficiency of the "e-machine" reduces the 25kW to 23.5 kW. Both the generator (REEM) and inverter (REME) have coolant lines, so some of the power of the ICE is lost at each stage before it becomes DC electrical power to the battery.ultraturtle wrote: I might also guess that a 4300 RPM / 34 hp / 25 kW limit may well be imposed upon North American i3s in order to maintain its astonishing 39 mpg EPA rating.
