iOS Shortcuts for battery charge and range

[Daveski3]

I created a few iOS Shortcuts for doing some battery calculations. I do use ABRP and PlugShare for trip planning but I've found a few instances where I was doing manual math to figure out what my battery charge would be after a set time. For example, we were on vacation at the South Jersey shore and my son was in a basketball tournament in N. Jersey. I only had my level 1 Ford charger to use at the vacation house which only gives about 1% per hour. I needed about 40% each way. I stopped at the only DC charger here in town and wanted to charge to 85% knowing that I could get the last 15% from my level 1. I plugged in and was getting about 44 kW/h so I did some quick calculations to figure out how long it would take.

You should be able to click the links and download the shortcut (iOS only). This is not my specialty. I just like to play with tech items and found a similar shortcut on a VW website and figured out how it was done.

Please share any updates or modifications you may have. Many of you will probably not have a need for these but I wanted to share for the few that might find it helpful. I put the shortcuts in a separate folder in the shortcuts app and then created a new shortcut that takes you to that folder and placed that shortcut on my homescreen so it's easy to navigate to the shortcut calculators.

I know these are basic calcuations and there are other variables that would affect the final result. These are just used for a rough estimate. Please be nice and don't respond telling me all the ways these could be off -- I know.

Here are a few NOTES:

• These are based on the Extended Range AWD model (91kWh Battery), change Shortcut formula from 91 to 70 for Standard Range.
• SOC = Battery current State of Charge (current percentage)
• These assume a steady state of charge, your charge rate could change if you are at a shared station or the charge rate decreases once you reach 80% or higher
• I live in the US so these are set up for miles. This could be easily updated in shortcut
• The mi/kWh is the miles per kWh. This number will change based on your driving. You can see your current mi/kWh in the Trip section of your car display (example, 3.3 mi/kWh.
• I use the term "charger" to keep it simple. I know that the car is the charger and the plug you plug into the car is the Electric Vehicle Supply Equipment (EVSE). I did this to keep it simple
• The basic formulas that I use for calculations are:
  • % x .91 = kW Example 65% x .91=59kW (If the car battery is at 65%, the battery has approx 59kW left)
  • kW x (mi/kWh) = miles Example 59kW x 3.3 (mi/kWh) = 194.7miles (if the battery has 59kW, you can drive approx 195 miles)
  • Miles / (mi/kWh) = kW Example 194.7miles / 3.3(mi/kWh) = 59kW
  • kW / .91 = % Example 59kW / .91 = 65%

Shortcut Links

“% Amt in “X” Time”
This Shortcut will ask your current battery % (State of Charge - SOC), how long you will charge at the current charger and what the charger kW/h rate is and tell you after X time what your battery percentage will be.

“Charge Time To Reach “X” %”
This Shortcut will ask the charger kW/h rate, your current battery % (State of Charge - SOC) and what the final battery % you want and will tell you the time it will take to reach that charge.

Ummm I have the extended bat (91 Kw) however my SOH = 92.5. I think the SOH makes a difference in this calculation. Also when I check my Kw to empty with a 100% charge it is 87KW indicating my actual SOH is 87/91=95.6 not 92.5? So that also needs to be included in this calculation. My point is that as the battery ages you no longer have 91 Kw available.

Again…these are basic conversions. If your battery is old and no longer at 91kWh, adjust the calculation accordingly.

Thanks for doing this. Do make sure that the units are correct. You frequently indicate kW (unit: power) where the correct unit of battery capacity is kWh (unit: energy).

Outstanding!

Thanks for providing these shortcuts. I have downloaded them and edited to my battery capacity.They will be useful
