Question: how much does it cost to fully charge a toyota prius prime?
Answer: The cost in electricity is comparable to a small air conditioning unit, measured at about $200 annually. The Prius Prime takes 7.2 – 8.8 kwh to charge a fully drained battery. If you were to charge it every night for 365 days during off-peak hours (6.5 cents kwh) this would equal 57 cents a day and $208.05 annually.
