Most of the EVs todays employ lithium-ion batteries as their power banks. This type of battery has a high energy density but is sensitive to temperature. In winter, lithium-ion batteries suffer from low temperature power performance. Drive range may drop from 20 – 50%. Latest EV models perform better as they are fitted with some climate control devices such as heat pump but the loss of range is still significant.
Drivers are always advised that in a cold winter they should keep a double of the charge as for usual days. For example, if you usually spend 40-mile worth of charge a day, you should prepare 80-mile in your battery in a freezing winter.
Preheating also means pre-conditioning your EV for driving. A warm battery is more efficient and a warm cabin makes those chilly morning commutes more bearable. Preheating can now be done with shadow charging, as it will hold the charge of your EV and keep unplugged till the start of your drive, making it nice and toasty for your journey.
Keep plugged in and let the passenger compartment preheated by the electricity from the grid instead of the precious energy already charged in the battery, saving the maximum energy for driving.
In 2021, the average time spent on charging 1 EV is 49.9 mins, but users may spend extra hours in the serpentine queue at a roadside charging station. In a severe winter EV charging takes even longer by 30 to 60 mins according to the feedbacks from users. So why the long wait? Just use Shadow Power to charge your EV and you may sleep or work over the long waiting hours.
