GLE450 hybrid battery?!
As the GLE 450 has an electrical engine boost (EQ Boost). So was wondering, does it have an extra battery to store the power or is it just the regular battery under the seat? and if there is an extra battery where is it located? is it mentioned in the manual?




So basically it has two batteries, one user-changeable and the other is by the dealer, and none of them is really that massive like some other hybrids, so won't be that big of an issue in few years when needed to be changed.
I'm asking as I was researching hybrid cars and the effect of high or low temperature on them (which isn't good on the batteries), thus batteries that are inside the car are better than the ones outside as it gets affected by the weather more.
FYI: Tempretuers here in Kuwait reaches 52'c (125'f) in the shade
and don't ask about under the sun. which worries me for new tech.So really appreciate the help.
I find it strange that the electric function is not more active when the car is being driven gently. It would make sense to me that the electric motor would very active in all acceleration modes, or is this a function low level of charge in the hybrid battery?
I have read how well the gas and electric propulsion have been integrated, hopefully this will be more evident once I push the car more.

What you describe is normal operation of the E-Boost. It’s designed for the stop/start allowing more seamless operation and to smooth out turbo lag by providing supplemental power under acceleration. The 48 is too small to operate like a true Hybrid, not its purpose.
0.9KWH isn't a huge battery, A long stop light on a hot day with the AC blasting will do a good job draining it (not to mention some lead foot starts).

Tesla expects them to last at least 8 years and infinite miles, since that's the warranty they offer with the Model S — they define the lifetime of a battery as being when it cannot hold more than 70% of its original charge. But actual data suggests that they will last longer.

One of my friends has had the battery in his Model S and the drive motors replaced twice within 40k miles.

So I'm concerned about the longevity of that 48V LiOn battery and cost of replacement. If we're talking about a couple hundred every other year, that's not going to bother me too much, but if we're looking at a few grand every other year, then yikes!
Sorry, waiting for my car to come in has the idle mind wondering about all kinds of things

My understanding on the Ready light is that it will go off when the battery is discharged to the %reserve limit established-a notice that it will not function for boost or start/stop. The reserve should be the limit set to keep from excess discharge and enough to start the car at least one more time. It would be nice to see a bar graph of the charge instead of the Ready light.
Maybe our resident expert Fabris can enlighten us with facts.

It doesn't matter if you do one long deep discharge down to the reserve, or many smaller discharge cycles that add up to whatever the reserve is, overall it's still going to count as 1 battery cycle.
I know someone with a Volvo XC90 T8 that is plug in hybrid with a 9.x KWH battery. They've already had the battery wear out at just over 50k miles. Granted that model actually can use the electric motor to drive the car. But I think they left it in normal/comfort mode 99% of the time and let the computer manage ICE vs EV motor and the charge cycles. Luckily they had an extended warranty that covered the replacement. Otherwise it was going to be a very expensive repair.




Volvo covers the battery for 8 yr/100k miles or 10 yr/150k miles depending on the state you are in.
They say the battery is good for the life of the car, but of the two people I know with the T8 hybrid, both has had problems with battery and electric motors. One needed battery and motor replaced, the second only had motor replaced but now battery is acting up.
Same with Tesla. I only know a handful of folks with Tesla. Everyone of them has had to have their battery and motor replaced at least once.
