How Much Does the Range of New Energy Vehicles Decrease in Winter?
1 Answers
New energy vehicles experience a range reduction of approximately 30% in winter, with the exact figure depending on the vehicle model and actual temperature. This is because as temperatures drop, the electrolyte in the battery becomes more viscous, increasing internal resistance and slowing down the movement of lithium ions. Additionally, the diffusion system of lithium-ion batteries within the active material decreases in low-temperature environments. Solutions to mitigate the reduced range of new energy vehicles in winter include: Parking the vehicle in a heated garage; Preventing the battery from getting too cold; Turning off unused electrical devices while driving; Driving smoothly and avoiding aggressive acceleration; Adding antifreeze; Ensuring the battery remains fully charged. Battery maintenance methods for new energy vehicles: Full Charge and Discharge: The simplest way to maintain a new energy vehicle's battery is to perform full charge and discharge cycles. After the vehicle is fully charged, continue charging for a while. Additionally, if there are no special power demands, it is recommended to drive in pure electric economy mode. Avoid using unqualified or modified power strips or charging devices. When the vehicle is not in use for an extended period, charge it fully before storage. These are basic maintenance practices that should not be overlooked. Pay attention to the charging and discharging range of the onboard battery. The optimal time to recharge is when the battery level is between 50%–70% or when the yellow light indicator appears. Scheduled Charging: If the vehicle is unused for a long time, try to perform a health charge once a month or use the battery until it reaches 50% after a full charge. The ideal environment temperature for battery charging is 25°C, which is difficult to achieve in cold winters, so indoor charging is preferable. If indoor charging is not possible, choose to charge during sunny daytime hours to enhance battery activity and minimize range loss.
