Battery range dropped 25% from spring to winter and 30% from summer to winter, with the researchers looking at temperatures near zero Fahrenheit for the coldest conditions and around 80 degrees in the summer.

Dropping from 70 to 65 mph on the highway will considerably boost the range of your EV. To maximize performance, keep your speed modest and consistent. High speeds might result in greater energy usage, reducing your EV’s winter range. Reduce Cargo Weight: Cold temperatures already impact EV battery performance.
Abstract: The driving range of battery electric vehicles (BEVs) is greatly influenced by ambient conditions, especially at low temperatures. To address this, the battery and the passenger cabin can be preheated using energy from the electric grid. This is regarded as a strategy to reduce the energy consumption of these vehicles in winter.
Cold temperatures adversely affect EV batteries because they rely on chemical reactions to store and release electricity. Lithium-ion batteries – the most common cells used in electric and hybrid cars – work when lithium ions move from the anode to the cathode; cold slows this process down and restricts battery performance.
Battery electric vehicles are less efficient when temperatures plunge, reducing mileage. Heat pump-based HVAC systems and warming up while plugged in can help, experts say. This video file cannot be played. (Error Code: 232011) Winter weather can cause bigger headaches for electric vehicle drivers than shoveling their driveways.
This is regarded as a strategy to reduce the energy consumption of these vehicles in winter. For long trips, preheating can indeed be translated into a slight increase in the driving range. However, for short trips, the amount of energy saved from the battery does not outweigh the additional energy demanded from the grid.
