If so what is the advantage of the winter package coming in a few months?
What is a battery heather? Did you mean "heater"? If so, the battery has a built in system to heat and cool the battery as needed. It uses it's own battery power if needed when the charger is not connected.
The Winter package is currently only available in Europe, so you'll have to evaluate what it includes for the price. We're in 90 degree heat right now (Northern California), so winter packages are not really on our mind!
Yes I meant heater! But from what I understand the Europe package comes with "upgraded" battery heater, never could find what the advantages are though.
I may be wrong, so please correct me if I am.
Optimal battery life/charging occurs with keeping the battery within a certain temperature range. Many of the European deliveries will be to potentially consistently cooler climates than in California or many other places in the US where Tesla are sold. Hence, the need for a stronger battery heater.
