Electric engines are much simpler and should last a lot longer than ICE, so that extra upfront cost will be divided over a lot more miles, and there will be a lot less maintenance expense.
I do think that electric has a lower maintenance cost, even accounting for the battery, but it's not that low that i think you can make up a 30k price difference.
If you plan on keeping the car for 10 years and drive 1000km per month. The up front 30k are 3k per year or 250 per month. That's quite a lot of an additional fixed cost for not having moved yet.
