There's plenty of options, check out PlugShare. Most people however charge at home - power into a garage or carport is pretty commonplace, and no special equipment is required.

$45k sounds high until you do the maths on petrol and servicing savings per annum. Depending on your lifestyle, distance travelled per year, access to free charging (solar, shops, etc) you can save $30-60k in fuel over the 10 years of warranty the battery pack has.

It's worth sitting down and doing the maths. You might be surprised the value proposition once you do it.
Honestly cannot understand who are those subsidies for. Recently I witnessed a few times a scene on a parking lot, which appeared to me as a group of overjoyed young people congratulating their happy mate about acquisition of a new ride (invariably a fancy Shelby Mustang or a mean-looking BMW, and invariably on their Ps) - you know, sniffing under the car, patting (the car and the lucky owner) on all surfaces, marveling from all distances. Laughing and selfying. The average age within all those groups, to my judgement, was around 16yo, so I highly doubt they could make full use of Salary Sacrifice incentive.

Going "carless" is also absolutely not an option, so if we must spend we're looking for maximum value and minimum outlay.
