That’s a lesson EV drivers in Norway learn very quickly. If you can’t charge at your destination, plan to visit a quick charger nearby, before arrival while the battery is warm from driving. Even using a quick charger, charging is very slow when the battery is really cold. Admittedly, I don’t have personal experience below –20 °C (–4 °F). If it drops down to –40 °(C or F), I am not so sure what will happen. But the strategy should remain the same.
