How long is the battery life of the Emgrand EV450?
3 Answers
The battery life of the Emgrand EV450 is approximately five years or 120,000 kilometers. Battery maintenance methods include: 1. Regularly inspect the battery; 2. Avoid excessively long charging times; 3. Gently press the brake when starting; 4. Ensure the battery is fully charged if the vehicle is parked for an extended period; 5. Protect the battery from extreme heat or cold. The Emgrand EV450 is a compact car produced by Geely Auto. Its body dimensions are: length 4631mm, width 1789mm, height 1495mm, with a wheelbase of 2650mm, ground clearance of 120mm, trunk capacity of 680 liters, and it features a 4-door, 5-seat sedan body structure.
I've been driving my Emgrand EV450 for over three years now, and the battery still feels quite durable. My daily commute is about 100 kilometers, so I typically charge it once a week. So far, the range has only decreased by approximately 8 kilometers. I always make sure not to charge it to 100%, usually unplugging at around 90%. In summer, I park it in an underground garage to avoid direct sunlight. A friend of mine has the same model that's been running for five years, and the battery health is still at 86%. He has better habits, sticking to slow charging and rarely using fast-charging stations. The maintenance technician said that with proper care, a ternary lithium battery can last up to 10 years, with the key being to avoid long-term complete discharge and high-temperature environments. The manufacturer's warranty of 8 years or 150,000 kilometers is actually quite conservative. For a household vehicle averaging 20,000 kilometers a year, it can last even longer. Battery degradation mainly depends on cycle counts and temperature management. It's recommended to periodically use a diagnostic tool to check the battery pack's balance.
I specialize in new energy vehicle research. The Emgrand EV450 uses ternary lithium batteries with a theoretical cycle life of 1,500-2,000 charges. Based on its 52 kWh capacity and actual range of 300 km per full charge, the theoretical total mileage should be between 450,000 to 600,000 km. However, in real-world usage, battery lifespan is more affected by temperature—for example, fast charging in high summer temperatures accelerates aging. The manufacturer's warranty promises no more than 30% degradation over 8 years or 150,000 km, which is a realistic figure. From the data I've analyzed, normal household use typically results in 10%-15% degradation after 5 years. It's best to perform a deep discharge calibration monthly—this option is available in the vehicle's system. Battery management systems are now much more advanced than five years ago, and effective cooling can significantly extend battery life.
