EV Range Calculator

I created a new app for the iPhone that calculates the range of any EV according to efficiency and battery size. It is easy to use and available on the Apple Store free of charge.

https://apps.apple.com/us/app/evrc/id6478421298

Features:

EV Range Calculator for all EV cars and trucks. Perfect for trip planning and knowing when to unplug the charger and get back on the road. On the road you can quickly calculate what efficiency is needed to reach your destination. Adjusting to a lower speed improves your efficiency, and assures you that you will arrive without range anxiety. EVrc is simple to use and quickly will confirm any range estimate for stress-free EV driving.

Why not just use a better route planner. It has built in efficiency numbers for most EVs, allows you to plan your route, specify ending charge amount.....

I agree that ABRP is a great app, but my EVrc calculator is designed with simplicity in mind. It's a tool to help know when to unplug the charger and get back on the road. It also is a quick tool to confirm while on route, if you are meeting the requirement of reaching your destination. It also helps new EV drivers learn about battery consumption. It's a free tool that I created hoping it would be of value.

Looks pretty cool! Any plans for an android version?

Nice. It works well.

EVrc in Apple Store

This update adds an odometer reading to the charging session data.
Keep track of all your charging sessions - including time charging, starting percent, ending percent, kWh added, cost, location and average charging speed. Saving this data will allow future updates of EVrc to predict future trips based on past history.

Awesome! Is this your profession or a hobby? Not familiar with app design at all; but I am curious.

My profession is owning a software company and developing Windows programs for 40 years. Coding apps for iOS is a new challenge for me - one that I very much enjoy. Learning something new was my motivation along with keeping pace with the present - and the future. This app is from me personally, not my business.

Owning my Lucid and the technology it brings, made want to keep data on my travels. I hate paper, so I coded an app to do the math and replace the paper. That is how EVrc got started.

I keep coming up with more ideas and hope to get feedback from users moving forward. I see so many possibilities in the future using the stored data and AI. These are exciting times we live in!

Android version planned?

I just assume in Pure awd that 1% is 3 miles worst case and I rarely go wrong.

This last week we made our semi-annual trip from Southern California to Chelan, Washington in our Lucid Pure AWD. This is the third trip with our Lucid on the same route (all very isolated desert). The total distance is 1,300 miles.

The first two times we made the trip in our Lucid (once heading north and the next heading south), I was experiencing some range anxiety because of not really understanding my car. I have learned so much on these trips and YouTube.

Earlier this year I decided to create an iOS app to increase my knowledge of my car and make my trips more predictable. One thing I learned was when charging for the next leg of my trip, the Lucid estimated mileage was based on its EPA rating and I would never achieve what was predicted. The car does adjust the range along the way, but when you are driving for hours out in the Nevada desert, you need to know before you go.

So here is what I found to be confusing with battery charging. The amount delivered by a dispenser is not the amount needed for range estimates. In my 2023 Pure AWD, the battery “usable” capacity is 86 kWh. The is the number needed for accuracy in estimating range. The dispenser will display amount added that calculates out to battery size of about 95 - 98 kWh. Some research explained why there is this difference and I have documented in EVrc.

I had the opportunity to put my iOS app (EVrc) to the test on this road trip and it was spot on. Before I left a charging station I would set my Lucid to the next planned charging stop and using EVrc calculate the percentage of charge needed according to how I drive. I would use the app to keep a reserve of at least 5% battery when arriving at my destination, using an average efficiency of 3.0 miles per kWh. If I was below that mark, I would slow down and get it back where I needed it. No stress, no anxiety because I knew my car and understood the numbers.

After getting back to my home in the north, I went to work on the app to make it more accurate calculating the usable battery size and worked on info buttons in the app to explain how and why. I also fixed a couple other minor annoyances

If you are interested in the charging data, I have attached the EVrc details of my trip for you to view. This is the best car I have ever owned and I am now deep in the EV information and technology rabbit hole.

There is a new release of EVrc that I submitted today and should be available sometime tomorrow.

Happy driving!

Ev Range and Battery Calculator - version 1.95

What's New:
Upgrade to Map - now shows EV Charging Stations when moving the map from your current location. It will also show the elevation change and distance when selecting directions to the next charging station.

Yesterday I completed several new features in EVrc and it is now available in the Apple App Store. Starting with my original release 3 months ago, the app has evolved from a range calculator to a “do everything related to EV transportation” app. I’m now looking at what else I can do moving toward version 2.0.

So far, the reviews have been 5 star and this motivates me to keep on going. I’m proud to say, downloads are now in the thousands in over 30 countries.

I would love some feedback on what features users would like to see on future releases. Please share your thoughts.

That would be great. I looked for what's available now, and nothing comes close.
