Which country are you from that you still have cheaper night rates for power? Or is that something specific to EV charging stations?
Germany had this for a while with storage heaters but it got phased out a decade ago.

I'm on Intelligent Octopus which gives 7.5p p/kWh guaranteed on any electricity use from 11.30pm to 5.30am. Outside of that, if you allow it to manage your EV charge schedule, you can actually get the lower rate at other times of the day I'm guessing subject to general grid load or wholesale costs dropping. For example, I've had my EV charge until 7.30am on a couple of occasions, still at the lower rate.
That sounds like part of it is subsidies. I talked with somebody at a electricity supplier a few years back and he mentioned possibly adding tarrifs aimed at grid load balancing in the future. So cheaper power for stuff like freezers if you turn their control over to the supplier. What you describe sounds similar.
