Looking for new EV long commute

Why do you only want to charge every other day?

I wouldn't spend many thousands extra on a car that has more range, just to save €100 per year because of free work charging.

This.

Why pay thousands or tens of thousands of euro extra to avoid charging at home? What happens if your employer stops allowing you to charge for free, if revenue remove the BIK exemption on workplace charging or if you move jobs to a company that doesn’t offer it.

You will almost definitely find a car that meets your criteria (or appears to) but it’s a limiting place to start. Modern EVs are highly efficient and night-time electricity can be incredibly cheap. I’m paying less than 6c per unit with Energia at the minute so a full charge of my 75kWh battery is less than a fiver. That’s less than 2k if I do a full charge every single day of the year. The savings compared to petrol are already decent but they’ll be eaten up by buying a car you don’t necessarily need.

The 58kWh has closer to 250-300km motorway range in winter, so you'd in theory have exactly enough battery to go 2 days. In reality you'd be charging every day in winter. The 77kWh version will probably last 2 days between charges

I'd echo what others are saying, it doesn't really make sense to buy a bigger battery to make use of a work charger every second day

To put some numbers to it, let's say you achieve an average consumption of 20kWh/100km

So your 150km commute would consume 30kWh on average per day. There's 240 working days in a year assuming you take some vacations, so that's 7,200kWh per year

At the current cheapest night rate of 6.87c/kWh, this will cost you €494.64. Let's make that €500 for simplicity's sake

The price difference between the 58kWh and 77kWh ID.3 is about €10k, so if managed to charge for free 100% of the time it would take 20 years to pay off buying the bigger battery EV

Of course if you want the longer range, then that's your choice. It is nice to have for when you wan to go on longer trips. But I wouldn't make the decision based on free charging
