Interesting. I didn't think any car-sized EV had used LiFePo4 because of the lower energy density. They are great batteries otherwise, though. I have two of them.GRA wrote:See viewtopic.php?f=10&t=6198&p=490239&hili ... ry#p490148 for testing of the 2015 Spark's battery. As I mentioned in the post following that one, the 2013s used a larger, more heat-tolerant, higher cycle life LiFePO4 chemistry.
I don't remember for sure now, but the Fit might have used LiFePO4 for the cathode along with their Li-Ti anode.LeftieBiker wrote:Interesting.

Two hours of L2 charging at 6 kW rate will increase your remaining range by at least 30 miles. The car does not need a rest and parking for 2 hours even without charging is not going to cool the battery in our climate. You need to accept that there will be faster battery deterioration in our climate because the average and maximum battery temperatures are much higher here than in cooler areas like the Pacific Northwest.osi wrote:I could take a break between 2 shifts to give the car a rest and a charge, like work through lunch rush and then go home for 2-4 hours and work later that day.
Yep. Heck, on my '13 Leaf, even 2 hours of sitting in ambient temps much lower than battery temp does virtually nothing. The battery has lots of thermal mass.GerryAZ wrote:...osi wrote:I could take a break between 2 shifts to give the car a rest and a charge, like work through lunch rush and then go home for 2-4 hours and work later that day.

2 mile deliveries are rare, rarer than .5 mile deliveries or even .25 mile deliveries. But yeah if I got a bunch of them in a row that would drain the car a lot. I think what I will do is just mostly take shifts with a good break in between, and if I ever run out of juice I can use my room mates hybrid car for little.powersurge wrote:That car is perfect For a delivery business....
However, if you drive 4 miles per delivery, in 12 deliveries, the car (with a perfect battery and no use of air conditioning) will be down to about 40%. (driven about 50 miles).
What you really need is a level 2 charger at the business to charge between deliveries... Otherwise you are taking a chance that you will run out of juice during the work day...
