Toyota RAV4 Prime Charging Times: How Long Does It Really Take?

You need to buy an aftermarket level 2 charger that will have a plug that fits into a 3 pronged dryer outlet (220 volt outlet). I got one on Amazon for about $220. The one I chose was nifty because it came with an adapter to change the 240 volt dryer plug into a regular 110volt plug. So I can use this charger on either 110v or 220v. The one toyota supplied only has a regular plug for 110volt outlet and it is only rated for 110volt. I have the 2021 Prime XSE with the 3.3kw charger package. I have owned for 11 months and have about 15,000 miles. There are a lot of aftermarket chargers available.

Both SE and XSE will accept 220VAC You would need to get a charge cable (j1772 EVSE) that has a 220v plug installed, some international EVSE units will accept 250v to 260v but it must be labeled as such, also look for the UL LISTED label. There are numerous brands, some allow you to select the charge current which would let you charge from a generator or a non-standard outlet with suitable adapters.

Page 114 in Owners Manual of Rav4 PRIME. Estimated Charging times: At a Commercial Charging Station with a 3.3kw Charger. Charging voltage at 240 V. Estimated Charging Time is Reduced to 4 hours and 30 minute. So they are explicitly telling you you CAN charge the 3.3kw with 240v.

Page 118 discusses using a public charging station to charge at your destination. There are no public charging stations that offer anything less than 240 volt charging. Toyota again is expecting you to use 240v charger with the 3.3kw model.

There are no guarantees on anything. We won't know if Toyota will honor the Lithium Battery Replacement warranty until some customers have successfully gotten the battery replaced. Toyota would never know you were using an aftermarket charger unless you told them. Especially since they expect you to use public charging stations.
I wish I had more answers for you.

All I can say for certain is that I have had the car for one year and have only charged 110v with no issues. I have used 2 different 110v chargers, one in the driveway and one in the garage, depending on where I park. I have not had any problems. I used amazon, not eBay, so I could read the user reviews of the chargers. That should help you to make a decision. The user reviews on EV Chargers are very detailed and written by people much smarter than me. In fact, you might get some answers there in the customer reviews of different EV chargers on Amazon.
I currently cannot spend $2000 to have a 220v plug installed. One day, I hope to have that available to me. I have never used a public charging station, it just doesn't seem worthwhile since I can drive on gasoline if needed.

Another thing to think about, no matter who made the vehicle, all Lithium Based Batteries operate on the same principles. Tesla tells their owners not to charge to 100%, but to charge to 80-85% and that will help the battery have many more "charging cycles". The toyota system ONLY charges to 100%. So no way to cut it off before that point. Even if you build the Charging Schedule to have the charger turn on at a certain hour, the Owners Manual says that it will ignore your start time and start charging earlier to reach 100% charge by your desired ending time.
According to lithium battery experts, that shortens the life of the battery. I even read this with my new iPhone, better to charge to 85% than a 100%. So I have started trying to time my charging where I don't get all the way to 100%. But hard to do manually. Again, who knows what Toyota might actually do if you try to get a free battery replacement 6 years from now. I think one thing that would be used against Toyota in court is that their charging system only goes to 100%. Which other EV manufactures warn against. Even if you try to use the Charging Schedule to only charge 3 hours, the vehicle will override your attempt to charge to less than 100%.
Overall I am very, very happy with the PRIME being my first venture into electric vehicles. I charge it all of the time and barely use gasoline because I like the powerful electric engine. At 13,000 miles, I have seen no decline in the battery at this time.
