Re: ProPilot using more charge?

Fri Sep 21, 2018 6:48 am

I’m hesitant to believe propilot uses more than 100wh, even that is pretty high. It’s a very simple system in terms of its capabilities. The other sensors are always in operation anyways so there would be no effect on consumption there. To put it in context a 15w apu should be able to handle all the calculations and have processing power to spare.

If I use propilot and go no faster than 95km/h I’ll get to work with 56-58% remaining. If I drive myself and don’t exceed 105km/h I’ll get to work with 63-65% remaining.

This has been verified with multiple trips and myself and my wife driving.

Anyone else notice this?
Based on calculations I have done previously using a 1000-W processing load (the maximum I consider conceivable in a modern car), it would take about three hours to consume 10% of the energy in the 2018 LEAF's battery. It appears your one-way commute only lasts about an hour or so, so it seems unlikely the extra 7% is due to processing.

Perhaps about 1% of the loss is due to processing and the rest is due to driving inefficiency.
