My friend's 18-year-old Chery Little Ant ran 170,000 kilometers, the battery cell failed, and the 4S store needed 18,000 to replace the battery cell, and he had to be responsible for the travel expenses of the manufacturer. So he found a repair shop by himself, bought a dismantling machine core and replaced it. The battery of the little ant is a Jiewei battery, 301. The main symptom is that the meter shows 310 kilometers when it is fully charged, and at the beginning, the remaining mileage of the meter is about 7,80 kilometers, and the turtle light will be displayed, limiting the power, if you don't charge it quickly, you can't charge it quickly, you have to charge it slowly for a period of time before you can use fast charging. Slowly, he ran to the remaining 200 kilometers and the turtle light was displayed, so he had to change the battery cell. The fuel cost of new energy is really provincial, 170,000 kilometers in 5 years, and the refueling of fuel vehicles of the same level will be 70,000 or 80,000. However, it is really expensive to repair batteries for new energy. I changed 14 strings of batteries at a time, and I still found a repair shop that cost thousands of dollars to get in, and I hope to use it for another two or three years....
