What are the impacts of new energy vehicles in Northeast China during winter?
1 Answers
The three northeastern provinces of China experience extremely cold winters. In low-temperature environments, the impact on the range of new energy vehicles is significant. Here are the specific details: Temperature: The normal operating temperature of a car engine is generally between 80°C and 90°C, with some high-performance engines reaching above 90°C to 100°C. In summer, the ambient temperature is already high, allowing the engine to reach its normal operating temperature within about 5 minutes after starting. However, in winter, due to the low temperatures, reaching 90°C takes much longer, not to mention maintaining this state. Therefore, a longer running time is required to achieve optimal operating conditions, naturally increasing fuel consumption. Additionally, at low temperatures, engine oil becomes denser and less fluid, hindering engine operation, which also requires prolonged engine running to warm up the oil and improve its fluidity. Two key factors: One is thermal insulation materials, and the other is electric four-wheel drive. Facing extremely low temperatures, achieving the same range as in southern regions is nearly impossible without appropriate thermal insulation measures for the battery. Therefore, only by improving the range will consumers in Northeast China consider purchasing new energy vehicles.
