Battery red in carwash, trouble ahead?

What did you replace the hv battery with last year (not sure what “revised one” means)?

Are there any dash lights?

What is the warranty on the revised battery?

I’d say that the battery is weak and is in the early signs of failure.

Good luck and keep us posted

 

never go into a carwash that requires neutral, unless the battery level is high and the a/c off. it is hard to determine your battery state of health, but even a good battery can have problems in that situation, and no permanent damage may have been done.

 

That's one sign of a weak battery but it's not a guarantee either. Keep an eye on the SOC meter.

GOOD LUCK!

 

yes the battery is weak and in trouble. You are probably seeing very poor mileage also. Who replaced the battery last year?

 

There are too many variables here to make an accurate determination if you have a problem or not. There are many many many warnings on this forum about going through a carwash that requires the car to be in neutral (since the HV battery does not charge while in neutral). You are obviously not the first, only, or most likely last, person to experience this.

How hot was it outside?
Was the AC running full blast in auto?
Was the AC running at a low speed?
These items make a big difference in the current draw of the AC compressor motor.

What was the initial state of charge when it was put into neutral?
Could it have already been low from waiting in line at the carwash?

If you have an android phone, purchase a bluetooth adapter for the OBD port and get some free apps (like Hybrid Assistant and Hybrid Reporter) that allow you to monitor/load test the battery. This will provide REAL DATA and voltage curves, not just keyboard warrior opinions such as mine.

 

have you L/100km changed?

 

What difference does it make, with a/c on or off? What causes this problem?

SM-G935P ?

 

Anything that puts more load on the battery will run it down faster. AC falls into this category.

Maybe late to say, but in future, just avoid those pull-along carwashes, that require the car in Neutral. Preferable are the type where the car just sits and the washing aparatus moves along the car.

 

Ac compressor is electric not belt driven. Puts a real good load on the inverter. The inverter literally screams when the ac is on. Its max load.

Load on the inverter is big load on the hybrid battery. That’s why in limp mode there’s not enough power to run the ac.

 

Thanks for the info, I didn't know that.
Living in Arizona, the A/C is always on.

Not sure if already said, but engine will not run to charge battery in N. Was the case in our C-MAX, betting similar here....

 

What happens when we are at a stop light for 30 seconds, or so? Is'nt the same thing? Or rush hour trafic?
Foot on the brake? Or in park?

SM-G935P ?

 

as long as you are not in neutral, the car keeps the battery to a minimum charge. if you get stuck in traffic, you will observe the bars drop to two, then the engine cycling on and off to keep it there until you start moving again.
but if you put it in neutral, you will get the warning on the screen, and if you don't take it out, your car will die on the highway.

 

In D or P no problem, just in N.

Sorry bisco, your post hadn’t shown in TapaTalk.

 

Be aware "revised" means they replaced the bad modules with modules of the same age that just so happened to be in better shape at that time than the ones that failed on you. So they are not new and all of the same vintage and the clock is ticking on that battery pack.

The only way to get brand new battery modules is to buy a brand new toyota battery.

 

Thanks

The engine WILL run without pressing the gas pedal when the computer decides that the battery needs it whether you are moving or not, as long as it is not in neutral.

But it does sound like you are close to having to replace the HV battery with a new one or else rebuild it again and keep chasing bad cell. Even a 2005, if it's in good shape otherwise, is a candidate for a new battery.
