The complex relationship between temperature and batteries make EVs batteries to drain much faster during winter than other climatic seasons. Most EVs batteries are built with Lithium-ion, which uses chemical reactions to store, retain and release electrical energy.
The Lithium-ion batteries chemical reactions are very sensitive to temperature and this is why any Lithium-ion battery drain easily during winter. Cold weather increases a battery’s internal resistance, slowing lithium-ion movement and reducing its energy capacity and efficiency.
So, it’s completely normal for batteries (especially ones built with Lithium-ion) to drain easily and drastically during the winter periods. More theories and practicals backed this up; colder temperatures increase the viscosity of electrolytes—the liquid that enhances the movement of ion in batteries.
In practical terms, an EV’s range can drop by 20-30 percent in freezing conditions, making EV winter performance less than optimal. Speaking less of how winter weather impacts the batteries—changes also come to how we use our EVs during winter.
Just as you know, power is needed for heating the cabin, defrosting windows, and running heated seats and steering wheels. All these consumer additional electrical power, which will certainly be obtained from the battery and making it to run out of energy easily than you can imagine.
Electric vehicles (EVs) doesn’t work like internal combustion engine vehicles, which use excess heat from the engine to heat cabin, defrost windows and run heated seats. EVs use their battery majorly for these functions, which adds strain and further reduces performance.
If you own a EV, do not worry too much about this natural problem because many EV companies are informed about this challenges and have technology in place to help solve the issues. One notable invention regarding this is the in-built preconditioning systems, which allow owners to warm the battery and cabin while the EV is still charging.
This helps preserve range and ensures the car is comfortable from the start. Manufacturers are also developing faster-charging batteries, including one that can add 185 miles of range in just five minutes.
So, what do you think about the practical solution EV companies are implementing on this EV’s challenges. Do you think it can solve the problem or it will only reduce it? Let’s know your opinion in the comments section.
