What is the range of the Lifan 820ev?
2 Answers
The 2019 Lifan 820ev has an official pure electric range of 401km according to the Ministry of Industry and Information Technology. The 2019 Lifan 820ev has a battery capacity of 60kWh and a range of 401km, which calculates to an energy consumption of 0.1496kWh per 100 kilometers. The Lifan 820ev uses a ternary lithium battery, which has higher energy density and lighter weight, making it very suitable for pure electric household vehicles. It is equipped with a front-mounted single motor with a maximum power of 100kW and a maximum torque of 240 Nm. The main factors affecting the vehicle's range are as follows: Power battery capacity: The battery is the source of energy, and the more energy the battery can carry, the more significant the improvement in range. Increasing battery capacity often involves not only improving energy density but also enlarging the battery pack's volume and stacking more battery modules. Mechanical transmission efficiency: Energy is transferred from the battery, converted into kinetic energy by the motor, and then transmitted to the wheels, completing the entire energy transfer path. The mechanical transmission efficiency of electric vehicles is particularly high, with motor efficiency exceeding 90%, and some can achieve 95% or even higher. Resistance: Mainly includes tire rolling resistance and air resistance. At low speeds, the energy consumed by the vehicle is primarily used to overcome the rolling resistance of the wheels. At high speeds, the energy is mainly used to overcome air resistance. At a speed of 120kph, air resistance typically accounts for about 80% of the total resistance. Vehicle's own energy consumption: The vehicle's own energy consumption can be divided into two categories: one is the consumption of the passenger compartment, such as the air conditioning system and infotainment system. The other is the energy consumption of the vehicle control system and powertrain, such as battery heating during low-temperature startup and battery cooling in high-temperature environments.
Owners who have driven the Lifan 820ev should know that its official range is claimed to be around 400 kilometers, based on standard testing conditions. However, in actual use, daily city driving can achieve around 350 kilometers, while highway driving or using air conditioning reduces it to just over 300 kilometers. The battery is particularly sensitive to temperature and driving habits. In the coldest winters of Northeast China, the range may drop to only 280 kilometers, and in the hot summers of the South, using air conditioning also drains the battery quickly. To extend the range, I usually press the accelerator gently, avoid sudden acceleration or braking, and maintain tire pressure at the recommended level, which saves a lot of power. Charging is very convenient: a slow charge at home overnight fills the battery, while a fast charge outside takes about half an hour to reach 80%, making it suitable for commuting. Regularly visiting the 4S store for battery checks and avoiding leaving the battery empty for too long helps maintain good performance. The operating cost of an electric vehicle is low, much cheaper than a gasoline car, but you must always keep an eye on the remaining range to avoid being stranded midway.
