Why do electric cars lose power quickly in winter?

Electric vehicles are one of the main means of transportation for people. On the one hand, electric vehicles comply with the long-term goal of "widely forming green production and lifestyle, and stabilizing and reducing carbon emissions after reaching peak" in the central "14th Five Year Plan". On the other hand, they also facilitate residents' daily travel. According to data from the China Bicycle Association, the number of electric vehicles in China reached 340 million in 2021, which means an average of one per four people. Electric vehicles have become an important mode of transportation. However, with the emergence of electric vehicles, the problem of significantly reduced battery life in winter has become apparent, and the bottleneck of battery technology has also affected the development of the industry to a certain extent. Batteries are also a key consideration element for car owners when purchasing a car.

According to the 2022 White Paper on China's Two Wheel Electric Vehicle Industry by iResearch Consulting, the main factors that car owners pay attention to when buying a car are battery and range (60.9%), quality (53.9%), and power performance (52.7%). The most common types used for electric vehicles now are lithium-ion batteries and lithium-ion polymer batteries, including lead-acid batteries, nickel cadmium batteries, nickel hydrogen batteries, etc. However, under low temperature conditions, electric vehicle batteries generally experience an increase in power consumption and slower charging. If users charge their electric vehicles at home, it is easy to cause fires. The issue of battery life often causes difficulties for electric bicycle owners and many electric vehicle owners. The fear of spontaneous combustion in summer and power outage in winter is a reflection of the inner feelings of car owners. Why do electric cars lose power quickly in winter? The main reasons include the following aspects:

1. Low temperature environments can affect battery performance, leading to a decrease in energy storage capacity and subsequently reducing range.

2. In winter, the temperature is low, and the electric drive system of electric vehicles requires more power to start, so operations such as acceleration, braking, and wipers will consume more electricity.

3. Frequent use of electronic devices such as headlights, heaters, and seat warmers during winter driving also increases power consumption.

4. Cold weather can affect the friction and air resistance of tires, increasing the energy consumption of electric vehicles.

The combined impact of the above factors results in electric vehicles performing worse in winter than in summer. Therefore, when using electric vehicles in winter, it is necessary to pay attention to sufficient battery power, reduce unnecessary power consumption, adjust driving methods moderately, and pay attention to electric vehicle charging stations.
