Obviously I don't want you exact location and destination, but intrigued where you are travelling from and to at that price of train, and also at that swift time to get in (at rush hour?) and that you can consistently find parking 'in' London and at that cost (for how long?). I've never parked an electric car in central, but finding standard parking used to be hard. I generally go to Stratford now and park thee and get the train in (if I need to - I'd rather just get the train straight to Stratford or Liverpool Street Station)
I had a quick random check; for peak tickets, it's close to £30 from Reading and Guildford, and mid-£20s from St Albans and Stevenage.

Anyway, comparing train prices to an electric car probably isn't the model that the pricing is based on.
Many years ago, I actually complained to my MP that it was cheaper for one person to drive a not-cheap car (<30mpg) than take a pre-booked off-peak train. The response (from a researcher at the DoT) disagreed, and showed that after incorporating amortised insurance, road tax, depreciation, and maintenance cost, it was comparable. But of course this was for a single traveller; for two or more travellers in the same car, there was no additional cost.
Anyway, it's not surprising that partial costs of an electric car are far lower than taking the train.
