Re: Install Double Batteries on Nissan LEAF Increasing Range to 160 Miles?

After reading the May 2017 post, I Googled the name of the proprietor of Hybrid Industries; I found this interesting web page from Hybrid Haven. It suggests that doing business with Hybrid Industries may not be advisable.

"Hybrid Industries" came up in another thread and I made these remarks about all the images he lifted from all over the place.

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Actually there is another way to increase the range too. What about Leaf Box Range Extender?

Is that also true if you put a couple tall guys is the rear seat and one in front?

Weight affects range in stop/go driving and uphill driving. It has minimal impact on steady speed level road highway driving. Safety would be a major concern for adding batteries to an existing car (weight distribution, secure mounting in case of accident, electrical concerns for batteries in parallel, etc.). Just to be clear, passengers are not a safety concern because the car is designed for them, but they would likely reduce the range a small amount (especially in stop/go driving or sustained hill climbing).

Yes agreed! Maybe put the extra batteries in seat belts! :lol:

It's just that as far as range goes, yes it won't be quite double with double the batteries, but it will be close. However, it seems like some make it sound like adding batteries would only reduce range, like adding an anchor.

Some continue to overlook the fact that added weight contributes to rolling resistance losses, and that at speeds less than
40-50 MPH, is greater than aerodynamic drag losses. The 24kWh Leaf battery weighs over 400 lbs, and adding a second
one would not have an insignificant effect on rolling resistance losses, i.e. 10-15% increase.
#1 Leaf SL MY 9/13: 74K miles, 48 Ahrs, 5.2 miles/kWh (average), Hx=70, SOH=78, L2 - 100% > 1000, temp < 95F (35C), min discharge (DOD) > 20 Ahrs
#2 Leaf SL MY 12/18: 115 Ahrs, 5.5 miles/kWh (average), Hx=98, SOH=99, DOD > 25%, temp < 105F

Yes, it should be accounted for. But there's no reason to exaggerate the disadvantages.

If you take a 3,300lb Leaf and add a driver and his stuff you get around 3,500lbs total. A 600lb battery would represent an 18% increase, and so you'd have at most an 18% increase in rolling resistance. But as you said rolling resistance is many times less than half the total drag. Now I'd argue that 40 to 50mph is quite high, I usually figure 25 to 30mph as the point in which aerodynamic drag begins to take more power than rolling resistance, but there are several variables that could put it that high. Still, that would mean at 50mph a 600lb increase would represent only a 9% increase in total drag at most. Yes, it could increase energy usage going up hills or accelerating, but that depends a lot on how you drive.

I know from experience that weight doesn't make you "not get near" your normal range. This whole summer I drove down to Montrose and back on a weekly basis. That's around 65 miles with a total hill climb of 6,000ft and a total drop of only 4,000ft with zero charging points in between. There were times when I'd go there and back quite empty. Other times with the car quite loaded with both a few passengers and all their stuff. I hardly noticed any difference in range. Would losing the passengers and adding a 600lb battery help? You bet it would because I'd be able to drive down there and back without charging in Montrose.
