Immediately plugged in after driving for 30 min at 70 mph

3 hrs 6 min 9.01 kWh
15 kWh / 3 kWh = 5 hrs.

It has been my experience if you immediately plug in the charger after running it at high speeds (75 -80 mph) for an extended period of time in the Summer heat there will be a battery cool down period before the car charger will accept electricity.

It is consistent on my charger that 3.3 kWh is flowing into the battery and if there were no pauses to cool down the battery it will take 4.5 hours from empty 15 kWh/3.3 kWh = 4.54 hrs charge time.

For the person taking 6 hours; allow the battery to cool before plugging in the charger.

3 hrs 6 min 9.01 kWh
15 kWh / 3 kWh = 5 hrs.

Excuse my English, but that's BS or let's jsut say confusing.
No R4P will charge at 9KW, and is it NOT what the OP asked.

EDIT: My bad reading! Sorry. 9kWh no 9kW - As CH420 points out, it shows what it has delivered in the past 3h6m which indeed means an avg of 3kWh consisten with my 3.5 charging trailing off towards fullness.

The picture shows an IDLE charging hookup capable of 9KW / 40A
But no Amps are taken, no power deliver and a very suspect 259V is indicated.

With Level II - as asked - You can charge 15 or 16Amps @ 240 which is 3.5KW
Just do the math - 4 hours is 4*3.5KW = 14KWH which is pretty much the usable range out of the 18KWH
The last half hour you'll see the charge rate come down, because that's how it is.
For understanding use a comparison with water filling a bucket through a hose from a reservoir about as high as the top of the bucket. At first it will run full speed, as much as the hose can handle, towards the end the pressure difference is minimal and the last bits go slower.

Cheers,
Hein.

 

I have that Accelev 6 kW model and it takes usually after my trips about 1,5 h. If battery is total used, max time is allways under 3 hours. That is very usefull to get loaded fast after daily trips. Total gas after 3000 km is now 2,9 L/100 km.

 

My full charges are always around 4:15. It’ll charge at a steady 3.3 for most of the time and just drop down for 1 near the end of the cycle.

 

Plugged into the public charger 1:45 min ago and it said 3.37 kWh

I drove 28 miles and averages 2.8 miles per kwh

When complete should be 10 kWh and based on charge rate it should be complete in 3 hrs total charge time or 10 am MST

 

Just finished charging and it averaged 2.94 kw per hour

Assuming full charge of 15 kWh it would have taken 5.174 hours from empty to full charge assuming 2.94 kw per hour charge.

Today I drove 28 miles. Display said 2.8 miles per kWh. I set cruse control to 71 mph for 26 of the 28 miles.

Assuming the charge of 10.353 kWh /28 miles actual energy consumption was 2.7 miles per kWh so the computer was off .1 of a mile

Total Range assuming 71.5 mph cruise control set ( 10 miles bumped it up to 72 mph) AC at 68 degrees medium fan setting, elevation increase 130 ft or close to flat would have been 40.5 miles

 

Ran the battery completely out

When I plugged into the public charger this morning display informed me 4 hrs 40 min

I will report back today how many kWh was added to a completely drained battery.

 

Actual Charge rate is consistent with charger claimed rate

 

14.62 kWh is the charge capacity of the battery on my Rav 4 Prime SE.

It took 5 hrs exactly to charge from empty

 

14.62 kWh is the charge capacity of the battery on my Rav 4 Prime SE.

It took 5 hrs exactly to charge from empty

Is that capacity as measured from the EVSE, or the car itself? (there's usually like an 8% loss between the two)

 

From my OBD II post; ScanGauge II working on RAV4 Prime

Here are my very early observations;

• Full Charge SOC observed %90.1 & %90.5
  Implying just under %10 upper traction battery buffer (less than 1.81 kW)
• Empty Charge SOC %13.7
  Implying that ICE turns on when battery still has 2.48 kW or more. I intentionally tried to trigger ICE on as late as possible, by driving the last mile very slowly (residential) and without any obvious energy draws (AC, music, fan)
• Full/Empty SOC imply maximum 13.81 kW EV (non-emergency?) traction battery capacity.
• Full tank of gas from dealer registered 13.8 Gallons
  Implying 0.7 Gallons worth of air gap at top of gat tank

Data from RussC post #11;
Observed EVSE Charge 14.62 kWh x %8 loss = 1.17 kWh waste heat.
Implied Traction battery power (14.62 -1.17) = 13.45 kWh.

So we get close to the same (normal) usable traction battery power capacity by calculating using State Of Charge (SOC) observations from my post. My implied 13.81 kWh calculated capacity is within %3 of observed charging value after subtracting charging losses.

 

It took 6 hours for me!

 

Rav 4 Prime SE

Chargepont: Public charge station

Accepted Charge 10.295 kWh
Time: 3:24

Average hourly charge rate. 3.027 kWh

If we extrapolate:

14.682 kWh / 3.027 = 4.85 hrs full battery charge.

 

R4P SE - JuiceBox 40

Zero miles EV range left, ScanGauge read 13.7% SOC. Charged 14.43 kWh to full in 4h 39m.

 

From empty to full 2:57 h. I have setting on charger ” Not full” and it works. 14,152 kWh. I can see my house wires quality (under 1,0 SOP is excellent), ampers, booster funcktion, house line voltage, charging Voltage and Grid A watching learning my house power needs. Charger is Accelev 6 kW EU model 2-phase, So its actually 400 V to 250 V transformer type and output 24 A comes from 12 A + 12 A phase 1+2.

 

From empty using a JuiceBox 32

 

Ran the battery down to zero miles EV left today. Then I went to charge at a level 2 charger around town. I tried 3 different ones. The first said 5h 30min to full charge. I charged for a while and then went to two more which both showed around 5hrs. What happened to the 4 hour 30 minutes?

 

Public chargers are frequently 208 volts instead of 240 volts like someone might have at home (this is due to the differences between commercial and residential electrical service). This results in public chargers being a slight bit slower than home chargers (some public L2 chargers will have proper 240 volt service, but it's less common).

 

Public Charger:

Took 4 hrs 56 min to charge from empty and the Rav 4 Prime battery accepted 14.685 kWh

14.685/296 min x 60 = 2.97 kWh charge rate per hour.

Pretty consistent with past charges I have tracked.

Initially, I believe the 3.3 kWh charger is accepting power at that rate, however, as you near completion I think it slows making the overall average just under 3 kWh.

 

I have the rav4 prime xse with premium package.

How can we see what speed its charging? In the charge settings under vehicle settings, I have three options. 12A, 16A and MAX. Currently its set to MAX, which is 32amps.
It is taking about 12 - 12.30 hrs to charge on 120v as expected.

Recently I charged at a public chargepoint charging station which was rated at 6.6 kwh, but my car was only using 3kwh, as per chargepoint app. It is shared between two cars when two cars are connected, or all the current is used for 1 car. Some one mentioned in the forum that if we set it to rav4 prime, chargepoint will use 3.3 kwh as default, and we need change the vehicle type to Tesla. So I changed it, and need to test this out.

Today, I used a public charge station, which is AV AeroVironment charge station. I was the only one using it, and it was charging at about 2 miles every 10 minutes. About 12 miles per hour. It was supposed to be 22 - 24 miles per hour when using 6.6 kwh charging.

I checked all the setting and trip history, but don't see how much fast its charging, or the current rate of charge. Other than just to show it will take 2 hrs 20 mints to charge, every time I open and close the door, when there was 50 % charge already charged.

Is it using the 3.3 kwh on board charger and not 6.6 kwh charger? Am I missing any setting? Or Am I reading it all wrong?

Soon I will be getting a level 2 charger, like juicebox 40, which might give more info in the app.

Thanks

 

So is the consensus the useable battery capacity is 14.6kw or 15.5kw? I’ve seen both posted.

 

@RedElmo, If you see 14.6kw or 15.5kw being charged to the R4Prime traction battery, then you have to subtract %8 charging loss (heat) for level 2 @ 16AMP to determine usable battery capacity. The wast heat did not make it into the battery.

I thought I made a good post about R4Prime traction battery usable capacity back in post #20. I used wall charging capacity and OBD State Of Charge (SOC) values to determine usable capacity.

Level 2 charger observed charge rate / time? Post...

Has anyone checked to see the rate of charge you’re getting or the charge time when connected to a level 2 charger? Does it appear to be more than 4.5 hours for your Prime ? Or, in terms of EV range on the display is it going up by 9.3 miles for every hour connected to a level 2 charger, or is...

Toyota used to double the unused buffer on traction batteries in previous hybrids and plug-ins. With the Toyota prescribed unused buffers in the traction battery, it will last 10 years, or they will replace it under warranty.

 

Yes I did see that post. Thanks. I guess I’ll ask it another way. How many kw does it take to charge up the depleted battery (including the losses)? I guess some show it takes 14.6 kw to fully charge the battery. Some show 15.5kw. Is it because the time it took 15.5 kw charge ate into the hybrid reserve portion of the battery?

Post any charge tracking results you get in this thread.
I saw someone online saying base XSE is taking 6 hours to charge on level 2, not the 4.5 Toyota says.
(an XSE premium package EV range should go up by 16.8 miles per hour connected to Level 2 charger.).

My R4P (with 3.3KW charger) charges at a rate of about 3.8KW with a 240V source, as measured on my watt meter, so it takes about 4 hours for a complete charge, (at 220V it would be a bit slower). It charges at a pretty constant rate for the first 13.5KWh then slows for the last one KWh. Attached is a picture of my charge rate, starting from 22 miles of charge, and filling to 51 miles of charge. Since I started from 22 miles range, the total KWh came to only 8.86KWh, but In previous watt meter tests it has taken 14.6 to 14.7KWh to fill the EV portion of the battery from min to max.
