In Russia, many cars have quickly removeable batteries & they bring
them indoors.  I expect you have a battery heate.r being too idle for
this.
Many cars there are fixed to run with no coolant in very cold weather.
They have specail draindown valves to empty the system completely.
None of this neccessary in our equitable climate.

Here in New England I've been able to use the electric start with no
battery warmer or block heater at -40 deg.  We use antifreeze mixed as
called for on the jug.  Only thing I do different when I know it will
be real cold is park the car so it's headed out of the driveway and
leave it in 1st gear.  When it gets below around -20F the shift lever
doesn't want to move.  It frees up after driving 1/10 mile.

In just few years electric cars will all be using super capacitors
rather than batteries.

The advantage of a supercapacitor is that it can absorb and electric
charge much more quickly than a battery - and would be ideal for

recharging an all electric vehicle.  The disadvantage of a
supercapacitor
is that it has a very low energy density ( a supercapacitor  would
have
to be much bigger and maybe heavier than a battery with an equivalent
energy holding  capacity).  I've also read that supercapacitors don't
hold their charge as long as a battery system does.  Given those
characteristics its seems to me that supercapacitors will
play an important role in the future development of  the electric
vehicle but it will not supplant battery technologies.
