As long as you enjoy the way you drive then I think that's one of the most important things. We all spend a lot of time in our cars and need to make sure we are not too distracted by the screens and the economy to look out the window. Read more: Easy steps to good economy | PriusChat
Weird, I thought it was standard for the OBD 2 port to not draw power. Guess that came out recently... My Bluetooth OBD2 won't work unless the car is in at least ACC mode.
Do you mean around 6/8 on the battery display or do you actually mean 75% SoC shown on a ScanGauge or similar? The latter is hard to achieve (and from what I can see, the dash display goes to 8/8 at around 73% SoC). This is very true. When the SoC is high the performance of the car changes significantly. My observation is that the car likes the HV battery to be 60% charged, equivalent to 6/8 bars on the battery indicator on the dash. Below that level it will seem to always take any opportunity to send charge into the battery - even when you're climbing a hill (within limits), which isn't what the marketing material would have you believe. Above 60% charge the car prefers to let the electric motor do more of the work. If you get the charge past a higher level (I haven't had enough observation yet to call out a specific figure) suddenly the car seems to just want to go nuts with the electric motor and it becomes very zippy indeed.
After a night rest, I opened the car with the mechanical key and released the hood/bonnet and measured the 12V battery. It was 12.09 Volts. Not too bad I think? Edit: I read somewhere that 12.09Volts means that the battery is ~20% charged.... Last night I drove 35 km with an average of 5.2 l/100km. Not bad, but I think I can do better.
The OBD2 port has a constant 12V pin, but no data is transmitted. When the car is off, I still can see the WiFi network the OBD2 dongle transmits, but there's no read out of data.
Today I took teh OBD2 dongle out and drove 45 km under perfect conditions: temperature was 21 degrees C , almost no wind, and I drove mostly on 60 and 80 km/h roads, only 2km on highway. My average for that trip was 3.9 l/100km. I think it will be hard or impossible to get lower numbers. One hour after this trip I measured the voltage again and it was 12.47 Volts.
