Unlike cars with internal combustion engines that use the engine’s “excess” heat for cabin heating, EVs face the physical limitations of lithium-ion batteries in low temperatures. To make your car more advanced and functional, we recommend using tuning accessories, a wide range of which can be found in our online store.
Main challenge: reduced driving range
The main issue in freezing weather is the slowdown of chemical reactions inside the battery. When the temperature drops below zero, the internal resistance of the battery increases, leading to two consequences:
- Capacity loss: In severe cold, the range per charge can drop by 20–40%.
- Power limitation: The Battery Management System (BMS) may artificially limit acceleration and regeneration efficiency until the battery warms up to its operating temperature.
Where does the energy go in winter?
An electric car uses a significant portion of its charge not for movement, but to maintain system operation:
- Cabin heating: Heating elements or a heat pump consume between 2 and 5 kW of energy per hour.
- Battery thermal management: To prevent degradation, the car uses energy to warm up the battery.
- Increased resistance: Cold air is denser, and winter tires plus snowy roads increase energy consumption due to friction.
How to minimize winter losses?
For comfortable operation, owners are advised to follow a few tips. First, perform preheating of the cabin and battery while the car is still connected to the charging station. Second, use seat and steering wheel heating — these consume much less energy than warming the entire cabin air volume.
Despite the whims of the weather, modern electric vehicles are perfectly suitable for winter. The main thing is to consider the laws of physics and plan your route in advance, taking into account available charging stations.
