Which utility is this, and what type of plan are you on? The time-of-day based plans can have extremely high pricing during peak, to discourage non-essential usage during those hours. We are on PG&E and they moved us (involuntarily) from usage-based to time-of-day in 2021. But they promised to refund us after a year if it was more expensive on the new plan than it would have been on the old plan. It was, and we switched back. I don't think we pay even close to 67¢/kWh on the usage-based, unless we're like triple our base allotment (which we aren't, but might be if our PHEV were a full EV). Sometimes it's also possible to put the EV on a separate EV account, so that you can have your main house on usage-based and your EV on time-of-day. Given how much you're paying, I'd look into alternatives (or not charge during peak, which most people don't need to do).
