Hello,

I just had my EBH installed by Wayne yesterday evening and used it for the first time this morning. I have it set for a 3hr heat up and I didn't really notice a difference in my first 5 min bar. When starting my car this morning I was on 2 purple bars and ended up being able to start my glide in the same place before using the EBH. Would I have been better off starting out with more of a charge, say 3-4 blue bars? I read through many posts and was not able to find the answer I was looking for. Any help or guidance would be great.

Edit:

This morning when I went out to my garage I started up my car and unplugged my EBH. My scangauge gave me a coolant reading of 160 degrees. I waited about 15 seconds till the engine shut off and backed out my driveway to find that I was able to glide at any speed right off the bat. I was pretty surprised that S4 came so early. My commute to work is 9 miles each way and I was able to grab a photo with my phone when I got to work. It looks like I was able to acheive a 50-52 mpg first 5 min bar. I'm pretty happy with the results and want to thank Wayne for installing this bad boy and all of you for the help. And how do you like that, 86 degrees out already at 5:21 am. The desert sucks.

My guess is it was related to the SOC of your battery. When you start your engine you have a tendency to use the battery during S1-S3. When you got to S4, you likely didn't have at least 5-6 bars, and thus you were not able to glide just yet.

I can usually P&G within 1/4 mile. And yea, I'd give it a little time, I suspect the low SOC was part of the problem for you this time around.

Good to hear. I guess thats the reason for the ICE running as usual this morning. The ICE stops charging the battery at 3 bars or 4?

Depends, sometimes just with 2 bars, it depends upon whether you're stopped, accelerating, steady state, etc.

Just remember, go very gentle for the first 30-45 seconds after entering Ready mode when using the EBH to minimize battery drain while the car works through S1...as soon as you're in S2 you should be able to P&G...just remember you'll need to get over 35mph before you can glide unless you come to a complete stop and let the ICE shut down on it's own to get into S4. Once in S4 you should be able to get into a glide from any speed below 41mph.

To give you an idea if I heat it for 2 hrs and the outside temp is about 15C it will heat it to about 35C. The car will glide at 40C so it take about a hundred yards to reach. It is summer in the UK so how it will perform in the winter will be interesting to see. I use a ScangaugeII to see the engine temp.

You will need a reasonable SOC. 3 bars plus

Ok, I have one stop sign in my housing plan about 500 yds from my driveway then I travel about 1/4 mile until I hit the main road. Would it be beneficial to sit at that 1st stop sign for a few seconds to let the ICE shut down then start my glide at a lower speed? Or do you think that is too early for me to be able to enter S4?

Yes I think it would be benefitial to wait at that first stop sign. It's probably not too early to enter S4 if your operating temp is over 150 at that stop....in the dead of winter it might be too soon, but most of the year it should be fine.

Awesome thanks. Yeah if I can get that low speed gliding in early (speed limit 25) that would be great.

Thanks for all the help guys.

I have noticed that with the block heater, after getting to S3/S4, it is best to get a little time, 1-2 miles, above 42 mph to put a charge on the battery and then drop back to the below 42 mph route. The battery charge doesn't cost much fuel, the ICE is pretty efficient at ~50 mph, and afterwards, I can let the hybrid control laws handle cycling between ICE and EV with excellent MPG.
