Hi Tony,TonyWilliams said:vsiev said:Is there a manual for the app or a reference to what all the numbers and info mean? (e.g. in the Distance to Empty (DTE) setting what does % State of Charge (SOC) Reserved mean and what happens when I change it from the default setting.)
One other question I have is if I leave the ELM327 in the OBDII port, will that drain the battery? I noticed a red light from the device when plugged in even though the Leaf is off.
There won't be a manual or instructions of any kind until the dust settles !!! These guys are coming up with ideas as fast as Jim can write the code. Pretty exciting.
DTE is simple calculated kWh's usable multiplied by a default factor of 4 miles/kWh (that's about 65mph down the level freeway, and fairly typical of around town economy). So, quite simply, 21kWh usable with a new condition, warm and balanced battery multiplied by 4 will equal 84 miles.
You can change the economy to a different value. Let's say you want to make a trip at 75mph, or about 3 miles/kWh. That same economy might also be typical of turning on the heater at lower speeds. Just put that in the program, and viola!, it will show 3 * 21 = 63 miles from a full charge with a new condition, warm and balanced battery.
Please check out the Range Chart link in my signature line to get an idea of typical economy values at typical speeds.
The reserve portion is just that; how much do you want to keep in reserve that won't show on the DTE screen. For my wife, I want it to run out where 0 miles means Turtle mode, and get off the freeway. Otherwise, if I reserve some %, she'll be calling me complaining that she's 20 miles away, and the DTE says 19 miles, what should she do. I would then have to explain that there X% in "reserve" and she won't believe me and then I'll have to go get her in a perfectly functioning car that could have made it.
Hope to see you at the June 8 San Diego meet (see signature line for details) where I'm sure somebody will have one or two of these.
Could you help add a 'formula section' to the wiki? I find your formulas and data posted very useful and will no doubt be very helpful to 'interpret' the app. Example: How many gids for Turtle etc. Thanks in advance!
