Winter battery charging question

Hi everyone,
Forgive me if this has been asked before but I was watching this video on YouTube recently about this guy in Montreal who parks his Soul EV outside at -10 degrees and in the screen shot, his range says 102 upon start-up. I start my car in Massachusetts at 5 degrees and it only goes up to 86. Is there something I can be doing (or get fixed) to boost my car's cold weather range? In warmer weather, of course, my range is just fine.
Thanks for the assist!

Montreal will be in km while you in the USA are in miles, 102km is 63 miles.

Ah, I confess I was never very good at the whole kilometer thing so I didn't even think of that. Thanks for explaining that to me. But I confess I was kind of disappointed - I was hoping there would be some thing I could do, that I wasn't doing, to get better cold weather mileage!

Thanks again!

Also, the range estimator doesn't show the actual range of a vehicle. It shows the estimated range, based on the last segment of the last drive. If you really want to see a higher number, shut the heat off for the last several miles of a trip, and drive slowly. In any case, the actual available range doesn't change - just the estimate.

Thanks, leftiebiker!
