Share your kWh!

I don't know about a limit, unless it is associated with a lease which we don't have.

Going way back to 2008 we bought a Prius. I did a lengthy spreadsheet about spending $5K more than the 2008 Civic which was our second option. I figured how many years it would take to save $5K in gas. The reality was it took much less time. We found that the Prius was getting such good mileage vs our 1999 Honda Odyssey (18 mpg) that we let the Odyssey sit as much as possible, using the Prius instead. So what was normally 22,000 miles per year, split 50/50 between those two cars was altered. We found the split was more like 20/80.

The same is true for the Clarity. We are at 37,407 today, having purchased the Clarity on Dec 5, 2017. That works out to 22 months, 1700.3 per month, average 20403 per year. Actually summer months we drive less so we will likely come closer to 22K miles per year by the end of 2019. Our 2005 Toyota 4Runner, that gets 13 mpg in the city, sits in the garage most of the time.

 

Wait what is this the PHEV? My dash doesn't look like that.

 

I track miles/KWh and show the monthly average in a spreadsheet. The numbers for the past few months are:
Apr=4.02, May=4.04, Jun=4.19, Jul=3.96, Aug=3.99, Sep=3.87

 

Looks like the EV version. Note the plug on the fuel icon on the right side. The 20K limit may apply to the EVs because I think they are exclusively available by lease?

 

Dang, wish the PHEV would show that info!

 

I got 4.8 m/kWh last month on my LEAF.

 

Are you making those calculations based on energy consumed while charging?

 

It's honestly pretty useless. The bar is always halfway full and goes up maybe 2-3 bars if you have the a/c or heater running.

 

Yes. I have a meter installed on the 240 volt plug that will measure 1/100 of a KWh. I divide the miles I drive by the KWh I use, keep a running total for the month and then take an average at the end of the month. The highest I have gotten for a single charge is 4.72 miles/KWh. I get a lot less in the winter when I have to use the heater. Some winter months are as low as 2.7.

 

Thanks. That would definitely give you an accurate amount of kWh’s you are paying for to charge the batteries and therefore the true cost per mile. If you factored in charger inefficiency you are probably getting about 9 kWh restored to the batteries for every 10 you are consuming.

Have you done a complete charge from 0EV? If so, how many kWh’s did that charge consume?

 

Yes, the last time I ran to 0 it took 13.55 KWh after driving 57.9 miles. Actually, the last .1 miles was with the engine running.

 

That’s great info. It fits right in with some other data provided on this forum that we only have access to ~65% of the batteries 17kwh capacity. Or ~11kwh.

0EV range and the car going into HV mode occurs when the battery reaches ~20% SOC and “fully charged” batteries are actually only charged to ~85%.

Your measured 13.55 kWh’s consumed would work out to ~11.5-12.2 kWh’s of battery capacity when factoring in a charger efficiency of 85-90%.

 

I typically charge to ~14.5 kwh, with a small bit of that preconditioning. I've [lately] been getting ~54 miles of mixed HW/City driving before the gas engine comes on, so ~3.7miles/kwh.

 

My trip meter reads 5.0 mi/kWh. I drive very smoothly and average about 25mph on my commute. No heat, no AC most of the time. In the morning I can get over 6 mi/kWh sometimes (more traffic, lower speed) and evening a little above 4 mi/kWh. I find that highway speeds really kills the efficiency. Which is unfortunate because that's when you really rack on the miles. I always forget that and end up short on a longer trip.

When my partner drives (like a normal person), 3-4 mi/kWh, right on target with advertised range.

I'm not going to get anywhere near 20k miles per year with the range of the BEV. Half that at most.
