I don't tend to top 2000 miles in any given month unless I'm doing a Scotland tour but my mileage is pretty sporadic. Hotels would be my main concern as I just book whatever is close to where I'm working. I would be concerned turning up to my overnight stop reliant on charging over night and finding nowhere to plug in.I do 1500 - 3000 miles per month and from what you've posted in the past I'd say we're in similar roles.
The charging time has to be work time. I work when I charge the car. I process e-mails, orders and make calls from the car while charging.
I always pick a hotel with a charger if possible. That's a good way to charge and not notice it. Likewise, I tend to eat in places that have chargers and charge then as well.
It's not as easy as running a diesel. It's just not. It requires planning and it definitely alters the way you look at mobility.
The upside is the saving in BIK on a company car. That's it. I wouldn't be in a BEV if it didn't save me a chunk of money on BIK taxes.
At the moment I tend to just deal with the super urgent stuff during the day and get to my destination ASAP then crack out the laptop so I guess I could shift that around. Funnily enough 'charge while you eat' was suggested by the person I mentioned. I guess that is pretty efficient from a time point of view but I imagine it is often a trade off between eating establishments and charging facilities!
All that said, like you I would make it work for the BIK but new car isn't an option from my employer right now let alone an EV with suitable range for what they expect me to do. By the time I do end up in one those zero / low BIK days will be a distant memory. Honestly what I would really like is a plug-in hybrid but it seems that these are being pretty much side-lined in favour of full EV which is a shame IMO.
