...Seven years ago, The LEAF was (and still is) a far superior BEV for most buyers, for having the "better" conductive battery cooling design...
My 2013 volt meanwhile uses the same kwhrs to charge today 47,000 miles later as it did new.
Discharges the same 10.3kwhrs today as it did new.
This guys EV range is within the margin of error
Maybe a battery temperature system is a good idea?
No, it's not, and neither was the Gen one Volt, as used by most of its drivers.
The primary message from that link you supplied is what an extremely poor PHEV design the gen one Volt was.
All the extra cost and complexity, all the compromises in interior and room and drivabilty, all the kWh drained from the grid, that Volt still got only ~59 miles of range from each gallon of the ~6,750 gallons gas it used, while emitting ~90,000,000 gallons of C02 just from the tailpipe
God-only-knows how many more millions of gallons of CO2 this monstrosity produced in the production process, and in generation of electricity so inefficiently used during the ~35% of the miles driven when it was not fueled by gas.
What the Volt gen one proved is that batteries carried in a refrigerated case and acting primarily as deadweight, rather than supplying propulsion energy, will indeed last a very long time
My LEAF, nearing the end of it's seventh (and hottest yet) baking North-Sacramento-Valley Summer, and after ~56 k gas-free miles, traveled 104.2 miles Tuesday on a single charge without even reaching the VLBW.
And also (possibly) nearing the end of my LEAF pack's first life
, it still has over 50% more electric range under all conditions than any Gen one Volt did on the day of delivery.
