This One Trick Can Save Your Toyota Prius Traction Battery
When you mention Toyota Prius and traction battery in the same sentence, owners seem to perk right up. Well that is what I am doing right now. I found a simple answer to a complex problem that can keep your Prius from having battery issues.
Opening The Door On Your Prius Shuts Down The Cooling Fan
I did not know this was even a thing until I was in a hybrid training course not two days ago. In the course we discussed "ready" off, or things that can cause the car to shut down. This particular act is opening the door.
What happens is, Toyota does not want dirt to get sucked into the cooling fan and blown over the HV battery. This can cause dirt and debris to build up in the fan and over the battery so Toyota shuts it off when the passenger door is opened. Stuff like this is not covered under warranty.
This became a big problem with taxi driver that would stand out with the door open signaling to others, they were ready to take customers. They would get back in and the car would no longer "ready" on due to an overheated battery.
What You Can Do To Prevent Battery Overheating
You will see threads on blogs, forums, facebook pages, and all over about cleaning your HV fan battery. There are gobs of youtube videos as well out there. Keeping the fan clean will allow adequate air flow over the pack keeping it as cool as possible for you given surroundings.
The other thing to do is probably not leave the door open when the car is in "ready" mode, and especially on a hot day. Keep the a/c on in the cabin as well while driving, to keep you relaxed and sending cool air back to that battery. It will thank you in smiles per gallon. Crazy how one simple thing can give you such a headache
If you remember nothing else from this article, just remember this. Your Prius is a solid car but it still needs love. Clean the fan, use quality fluids, and for heaven's sake, keep the doors closed when it is hot outside. Enjoy your weekend everyone.
