For the regular owners, how are you finding the remaining range display or battery % for accuracy?
I’m one of the worst for running my vehicles down to their low fuel light comes on and use the trip display for litres per kilometre read out to give me some idea of where I’m at needing to fill up.
On the battery side, I’m also terrible with my electronics from a completely different angle. I always like to plug them in without considering their state of charge so, I start my day with 100% and of course when I’m driving its plugged in because i don’t have a modern machine for wireless carplay to display waze and take calls and shout out txt replies etc.
So, I effectively kill my cell phone and to a lessor extent my tablet batteries prematurely. And yes, I’m intelligent enough to know I’m doing this yet, dumb enough to continue to do it. At least I don't ask for a safe space from judgement of others!
I would likely adjust my behaviour for an EV but, I do rely on my fuel use and gauge and have concerns about state of charge and changes in range and don’t want to beat up the battery either.
Every EV has the ability to set the upper limit that it will charge to (for additional battery preservation over and above what the manufacturer has built in). Early Bolts only had a choice of 100% or "hilltop reserve" (which set it to 88%) but that's long gone, on the newer ones you can set it to anything in 5% increments and there is a separately adjustable global charge limit and a "home" charge limit (provided, of course, that you have set a "home" location so that the car knows it is home). If you want to change the home charge limit because you know you have a long trip the next day, it's really easy. So, you basically find out what charge limit results in you using the middle of the battery's charge range on a daily basis, and set it to that. Mine is at 75%.
The "home" charge limit also allows you to set up a preferred departure time, which I have set to the time that the overnight charging rate ends. You can also override this really easily if a special circumstance arises - "charge now". It can also be overridden outside the car by plugging the car in, unplugging it, then plugging in again. This overrides the delayed charging and starts it charging now.
With that set up, you just plug the car in the last time you get home for the night, and unplug it the next morning when you go out, and it figures out when it needs to start charging so as to achieve your set charging limit by your departure time. This way you're normally only paying the overnight power rate.
This allows you to use a "dumb" Level 2 charging unit (EVSE) that just switches on power when you plug in the car. It is also possible to buy fancy ones that include features for starting and stopping charging and monitoring them online, but you don't need any of that.
The next step is going to be smart-grid integration with bidirectional charging, so that the car's battery can be used to buffer the power grid. Then you need an EVSE that is designed for this purpose and integrated into the building's electrical distribution. There are some EVs that are capable of bidirectional charging. The Ford Lightning is one of them. The Hyundai E-GMP cars are another. I believe the VW ID... cars are hardware-capable but it may not be implemented yet in software (don't know if this has changed recently). Older-design EVs including mine are not capable of this.
