Add-on battery pack plus 3.3 charger for 6.6 kWh total

Wed Aug 01, 2012 6:17 pm

I'm posting a poll to find out interest in a rear mounted battery pack for the LEAF with integrated 3.3kW charger. When you plug into the charger, your existing 3.3kW charger would get full power, and the auxiliary charger and battery pack will get the remainder (close to 3.3kW).

An option might be to have a second, dedicated J1772 for the aux battery so you can quick charge the main battery whilst 3.3kW charging the aux battery. It should be OK for lease cars to be refitted back to stock.

So, not really looking for snarky comments of why somebody might want this, or it's not good for you, etc.

If this is a modification you'd consider, here's the ballpark pricing:

6kWh - $8000
8kWh - $10,500
10kWh-$13,000
JAMP JR tm, the low cost 40 amp J1772 charge station
JESLAtm, the premium 40 amp J1772 portable charging solution
JLongtm the J1772 extension cord
JdeMOtm, the CHAdeMO outlet for your electric car
JDaptortm, the J1772 power outlet

Interested
But this seems kind of steep.

6kWh - $8000
8kWh - $10,500
10kWh-$13,000

It may depend on the cells. But I could use a bit more range..

+1
The price does temper my enthusiasm. perhaps at the point my batteries need replacing, I'd do the whole thing...

I would be intersted in this add-on, but the price is steep. Not looking forward to severly reduced range in cold winter months ahead.

Does seem a little steep, an 8kwh pack from Enginer for a Plug in Prius conversion is only $5500.
2011 Nissan Leaf sold after 33,000 miles
2012 Chevy Volt sold after 28,000 miles
2013 Toyota Rav4 EV 11,000 miles and counting!

I would be interested, but yes, I like the Enginer price better.

i think battery pricing is set to drop when the supply loosens up. although i expect Nissan to use the extra packs for warranty purposes since their "appears" to be a need but I am sure someone will find a way to snark some for the aftermarket mods that are bound to be abundant

That really isn't a fair comparison. It's similar to saying both a '65 VW Beetle and a 2012 Buick are cars, so why is the Buick more expensive?

First, as having researched the Enginer kit from almost the beginning, but having no firsthand knowledge, I can still safely say that the Enginer kit's components are not stellar. The inverter is questionable, (I don't know if the proposed Leaf kit has one or not), and obviously it won't have a high quality 3.3kw charger as the proposed Leaf add-on kit. The kit adds a minimum amount of electrical energy to the Prius, so it doesn't throw the parameters for the Prius out of range. It is far from being as sophisticated as a Hymotion kit or others, which also have additional electronics to allow more battery energy from the kit. I would expect the proposed Leaf add-on kit would be more than just sticking two wires from the kit to the original Leaf battery. Also, the Enginer BMS, at least from back when I was researching, was dubious. I would suspect the BMS for the proposed kit would be of much higher quality.

I would have really thought that the each additional 2kw for the higher power kits would not have added $2500, but I don't have any information about the proposed battery for the Leaf kit.

So maybe a bit more information about the proposed components and the complexity needed for the add-on kit would be helpful.

As has been seen before, range extenders for electric vehicles can be very complex. I remember the "Long Ranger" proposal for the Rav4EV. http://www.evnut.com/rav_longranger.htm

I might be interested in something like this once my warranty is up (18 months). But not before. And my finances would also need to improve before I could consider it too.
