My 02 Maxima (bought new) came w/tires that were way overinflated above door placard values. I stumbled across that and figured that might've been to help prevent flat spots while in storage/on the dealer lot.

2. Open the hood at the one Chademo planned to see if it reduces rate of battery temp increase.
Doubtful it'll help much. You'd really need a lot of forced airflow of air at much cooler temps to do much good. Immersing most or all of the battery casing in liquid that's much colder than ambient air temp would probably help.

The only other thing I do is drive in B mode the majority of the time I'm on the road and try to "coast" as much as possible when needing to slow down.

B Mode (and ePedal when available) work great for city driving, but Eco alone or D alone are better for highway use because it's so much easier to coast.
I can't stand driving with the ePedal lol I like the B mode because it slows me down faster when traffic slows in front of me. I was originally only driving in Eco mode and doing a true coast like I did with my hybrid but I feel like I retain my range better with B mode. I should really do a true test one week vs the next to see the difference personally but I don't have the patience nor reliable traffic conditions for that sort of test to be comparable without too many variables. :|

We only had the car for the last 10 days of the month, but our Efficiency was:
642.5 miles
4.3 miles/kWH

It was really hot most days, so the AC was running almost all the time.

As you can see I'm pretty consistent with kWh. So, for August I decided to try and get max efficiency for my normal commute. Since, I'm adjust multiple variables at different intervals, this is not really a test as it is an attempt to get the best possible kWh for one month. I'm implementing 3 approaches:
A) Adjust my driving, primarily minimize acceleration boarding highways
B) Increased PSI. it was set at about 36 cold, bumped it to 40
c) Use a few different drive settings. e.g. Eco , B-mode, D-mode. For the last 3 months I've driven exclusively in Eco + D-mode.

Initial indications are positive, one week in:

Nice improvement.

You can even go a tad higher on the tires if you are ok with the stiffer ride. I also find that D is better for the highway, as you don't generally want alot of regen (short of coming down large hills/mountains), rather conserve momentum.

I can only do the long slow highway accelerations when its really light traffic, and by myself as no one else can stand it. I also try hard to keep my foot in a constant power position, but that's difficult to maintain. Usually at or just below the first bar of power on the highway.

Transport Evolved has a piece on using the adaptable cruise. If you stay with a pack of cars, potentially using the adaptable cruise hanging with the crowd can possibly give you a gentle boost to your efficiency.

August efficiency continued to tick up, 4.5 overall so far for the month.

I think I am in that Goldilocks period where temps are perfect and the edges are now worn off the tires so often I am touching or exceeding 6 miles/kWh on around town trips. Fully enjoying tires which have a sidewall suggested 44psi. The average is weighted down a bit from the early part of the month highway trips.

On the freeway or anywhere really; Eco helps with efficiency by leveling power output. There is no loss of acceleration. Eco only dampens acceleration response to pedal movement.

Tire pressures do help. Some contend they feel a difference in ride comfort. I tried 36 PSI for a week over my normal 42-44 PSI and couldn't tell other than 36 has a lot more body roll and instability in roundabouts.

B mode has a higher level of regen. The best option is maintaining a constant "power" level (notice I did NOT say speed) and adjust for traffic conditions. But that is not always possible or easily predictable so when a reduction of power is needed, B mode recaptures significantly more power than D mode.
