Cutting the cost

Charge overnight on an off-peak or dedicated EV tariff, or during the day if your solar is exporting anyway. You rarely need a full charge every night, so top up to your usual daily range instead of filling to the top each time. Set a scheduled start so the car waits for the cheap window, and steer clear of charging through the early-evening peak.
