The main factors contributing to the highest battery power consumption in electric vehicles are primarily related to driving habits, ambient temperature, and the use of on-board devices. Sudden acceleration and braking cause the motor to operate at maximum power, potentially increasing energy consumption by over 20%, while maintaining a steady speed of 60-80 km/h can significantly reduce energy usage. Low temperatures have a particularly notable impact on battery performance; the range of lithium iron phosphate batteries may decrease by 15-30% in winter, and if the heater (which consumes more energy than cooling) is used simultaneously, overall power consumption may rise by 30%. At high speeds, increased aerodynamic drag leads to 15-20% higher energy consumption compared to urban driving when exceeding 100 km/h, with further increases under conditions like hill climbing or heavy loads. Additionally, low tyre pressure (below the standard 2.5 bar) increases rolling resistance, while the climate control system (particularly heating) can account for up to 25% of total energy consumption at full power. Vehicles with 800V high-voltage platforms (e.g., Xinghai S7) demonstrate superior energy efficiency, making them ideal for range-conscious users.
