The e-NV200 is likely to have an all-electric driving range less than that of the Leaf, which is rated on the US EPA test cycle at 84 miles. Media reports of a 120-mile range are based on Japan’s JC08 test cycle. (Source: Nissan Motor Co.)
For any trip under 30 miles roundtrip, electric is significantly better.
What I don't understand is why the USPS never switched their whole fleet to
electrics back in the 70's.
The average mail truck goes 13 miles round trip, the average speed is only some 4 MPH, and the peak speed is only about 35 MPH, There is almost zero requirement for highway speed and these are operated from a fixed base by a bunch of procedure oriented, operational bureaucrats. By going to EV the fleet maintenance becomes much simpler, and
given the short ranges you don't really need complex charging systems, just run 48 V DC out to the slots, and a simple charge monitoring circuit to keep the batteries from cooking.
You have time during lunch to top off, and you have all night to slow charge, this is ideal.
"FEDEX residential uses smaller trucks rather then the big Panel trucks. These would be ideal for Postal workers. I actually don't know why the USPS didn't already convert their entire fleet to electrics. The average USPS delivery route is 13 miles, the vehicles return to the post office twice/day, the post office is an ideal bureaucratic fleet manager. Given the very low speed of the USPS fleet, you can use cheap motors and lead acid batteries."
Patb2009, it's a good option for mail and courier/parcel delivery. Since fuel costs are less, cost effective too.
