Re: [EVDL] Improving Leaf economy & range.

I thought the Leaf used a water heater and a heater core. at any rate I saw 
a diy project where a guy replace his i-MiEV heater with a kerosene heater.

What about the cabin heating?  If you have an older model (I have 2011), 
it's resistive heating.  One recent day, I got just 45 miles of range 
before hitting 1 bar (outside temp around 45F).  A lot of that poor 
range was due to climate control (including defrost).

I did a quick google search but didn't see any posts on how to upgrade 
the heater to a heat pump.  Don't even know if it's possible without a 
good deal of customizing and ripping out stuff.

However, if possible, I think it would be a good gain for in-city trips 
where air drag is not so much an issue.  Another plus would be, I 
presume, quicker supply of heat.  The stock heater takes nearly 10 
minutes to warm up the cabin.

Re: [EVDL] Improving Leaf economy & range.

2015-12-24 Thread brucedp5 via EV 

Lawrence had posted about this a month ago:

http://electric-vehicle-discussion-list.413529.n4.nabble.com/Improving-Leaf-economy-range-tp4679309.html
 ... I was reading online that capping the grill, moving the license plate,
reversing the mudflaps and pumping up the tires to 45psi will give you 20%
better economy with the Leaf. I'm thinking fender skirts would help as well. 


My response was to look at hyper-milling as a major range gainer
http://electric-vehicle-discussion-list.413529.n4.nabble.com/Hypermiling-for-better-range-td4678457.html


My S-10 Blazer conversion EV [
http://brucedp.150m.com/blazer/
] was so energy inefficient (especially when compared to a production EV
like a Leaf), I had paid to add some aerodynamic efficiency (air-dam) tricks
to my EV. That is when the front grill was changed to a solid air dam with 6
AC inlets (powering the 6 on-board chargers).

I also had the underside of the Blazer smoothed out with a long flat
surface, as three sections of thick black plastic sheeting (from TAP
Plastics) held in place with Zeus fasteners (so they could be removed for
repair work, etc.). 

There was also an air dam placed in each front fender well to block off air
turbulence in and out the ice compartment. I had to make a return trip to
the shop to have that adjusted as it was interfering with the tires when
they were turned sharply. 

All that time, effort and money paid off as better range, by 3% at highway
speeds (55mph). However, that ice-compartment was so sealed up, that the
air-cooled controller was air flow starved. I had to return to the shop and
pay to have several large holes punched though the front air dam to give air
flow over the air cooled controller at speeds above 35 mph.

Was it worth it? At the time when there was nil public EVSE, and what there
was was L2-6kW at best (no L3), with huge gaps inbetween, I needed my 2 ton
lead-sled to have as much affordable range as possible. With a 55+ mile
PbSO4 pack range and up to a 22+kW charging ability (depending on the power
available), I was able to push my EV driving trips to the max. 
Yup, way back then, it was worth it (for me to throw money at the issue).

Today, there are so many efficient production EVs available and so much
public EVSE than ever before, ... I would be thinking differently than back
then if air-dam modifying is really worth the minor gain.

Re: [EVDL] Improving Leaf economy & range.

2015-12-23 Thread Bill Dennis via EV 
The new 2016 Chevy Volt has front grill shutters that automatically close at 
high speed, when less cooling airflow is needed, then open up at lower speeds 
to let in more air.  So that's one possibility, even if you control it manually 
yourself.

The only other thing I can think of would be add a front spoiler.

The underside is probably already smooth.
