more EV range with double charging ?

I’ve already done it, it won’t accept a charge, the light comes on for a few seconds and goes out. The evse never actuates

 

unfortunately, i don't have any equipment to measure things except a simple volt meter. i have never hooked up an obd, and have no idea what the battery charge has been over the years.

 

scangauge said SOC was 84 or 86% when the PiP was fully charged (from memory) I have a picture somewhere.

 

Hello everyone

On our 2012 model the charge varies a bit. Currently it is in our garage around 7°C and our Prius charges to around 80%. I've noticed that during the summer SOC went up to 85%. If i have more than on charge a day i currently stay around 83%. I believe that this is based on the battery temperature. Also if we start to go downhill, the battery will not rarely charge over 83%.

I've also noticed that the car starts an charging pattern once it reaches a certain level ov charge, were it reduces the charge and (I assume) starts balancing the batteries. I think (haven't tested) that this i based on SOC and time.

I also could image that Toyota implemented an safety feature, which shuts off the charging after a certain time. Maybe if you start charging around 50% the car would go back to 80%.

Kind regards

 

Real professional battery engineers know that changing the type of battery usually also requires changing the charger too.......to get the best charging performance.

In this case, I think you are lucky that it will continue to charge the second time.
If the characteristics of the Li battery were a little different, it might not.

 

Does anyone have the voltage after a full charge in the PiP?

The Prime full charge voltage is 374 to 375 volts (depending on how long after charging stops, and voltage is read). 0% ev SOC is 330 volts - with about a 5 volt buffer (meaning 325 volts can be seen at times as long as the voltage rebound after load is removed is 330 volts or above).

 

Just checked my 12 PIP after plugging in to my L2 evse Friday on timer to charge at midnight Sat morning. Sunday morning now and it says 84.72% 220v. Unplugged and plugged in again and EVSE says it's connected but no power going.

 

Thanks for all your work @jacktheripper !

 

Does charging stop part way to full SOC when using L1 and L2?
Does A/C work the same while charging? easy test : sit in PiP while charging on a hot day, Push A/C button on fob.

 

Noted

 

Just out o curosity. Where you able to get around the chargingissue?

 

Hi! We are testing a new charging procedure tonight. I will update once results are in!

 

Will update with results

 

Indeed as stated above it’s a safety feature implemented by Toyota. A simple solution is using a cycle timer.
