What is the range of the BYD e5?
2 Answers
BYD e5 utilizes a ternary lithium battery with a capacity of 60kWh, and its official NEDC range is 405km. BYD is a Chinese automotive brand, with BYD Company Limited established in 1995, starting with a team of over 20 people. By 2003, it had grown into the world's second-largest rechargeable battery manufacturer and established BYD Auto in the same year. BYD e5: The vehicle has a body length of 4680mm, width of 1765mm, height of 1500mm, and a wheelbase of 2660mm. It adopts a front-mounted single motor drive mode, with a total motor power of 100kW and a peak torque of 180Nm for the front motor. The NEDC pure electric range is 405km, equipped with a 1-speed fixed gear ratio transmission, MacPherson strut front suspension, and multi-link independent rear suspension. Factors affecting electric vehicle range: Power battery capacity, mechanical transmission efficiency, tire rolling resistance, air resistance, etc. The range is directly related to the three-electric system (battery, electric drive, electric control) of the electric vehicle. Battery System: The capacity of the power battery directly determines the range. Additionally, excessively high or low temperatures of the battery system can also affect the range. With the same battery capacity, more stable battery temperatures better ensure the range. Electric Drive System: Mainly includes the drive motor, controller, inverter, and reducer. Its efficiency is determined by the ratio of input power to output power. When the battery capacity is fixed, under the same voltage, the output energy is determined by the efficiency of the drive system. Automakers strive to maximize motor and control efficiency to optimize energy consumption and improve range. Vehicle Control System: Primarily coordinates the relationship between the battery, drive system, and chassis braking energy recovery. Under conditions of frequent acceleration and deceleration, it can dynamically adjust the proportion of energy recovery (braking energy recovery) based on the battery's state and braking demands, thereby improving energy utilization efficiency. In addition, the braking energy recovery strategy of electric vehicles can directly increase the vehicle's driving range.
As a ride-hailing driver, I know this car's performance best. With a full charge, the NEDC range is rated at 400 km. In summer, driving with AC on at a steady speed, the actual range reaches around 360-380 km, while in winter with heating on, it drops to about 70% of the rated range. However, fast charging is really convenient—just a half-hour charge during a lunch break can add about 300 km of range. Once, I drove from Chongqing to Chengdu, and a quick charge at the Suining service area was enough for the trip. Now, after 80,000 km, the battery degradation only seems to have reduced the range by about 20-30 km.
