Is your Prius HV Battery overheating?

The Prius battery is a great design but it must be kept cool. It is really important to make sure that your Prius battery cooling system is in good operating condition.

There is a cooling fan located in the rear trunk area of the car that should be inspected at least annually. Perhaps more often if you travel with a dog in your car. The cooling intake duct is located in the rear seat area and will easily fill itself with dog hair and cease to cool the High Voltage Battery. This may set a MIL code and cause your warning triangle to illuminate. If this happens it can be easily repaired if it is addressed promptly. It is really important to have your car inspected quickly for any warming lamp.

A battery that is overheated for an extended period will have a shortened life. It is possible to have a cooling fan that is partially clogged. This may not set the code but still be harming your HV battery.

HV cooling fan inspection is part of our regular service at Sturken’s San Jose Hybrid Shop.

If you have not had your battery fan inspected in the last year, it probably should be looked at.
