Yes, it has an impact as overcharging can damage the battery. Here is some relevant information about the Wuling Mini EV: 1. Introduction: The Hongguang MINIEV Macaron is an upgraded model of the Hongguang MINIEV under the Wuling brand of SAIC-GM-Wuling. 2. Exterior and Interior: The Hongguang MINIEV Macaron has undergone adjustments and upgrades in its overall design. For exterior color schemes, the new model features three lip colors jointly released by WULING×PANTONE UNIVERSE: White Peach Pink, Lemon Yellow, and Avocado Green. Additionally, the newly designed Macaron emblem is embedded on the left side of the vehicle, serving as a unique identifier for the new model.
I've driven the Wuling Mini for half a year and encountered this issue. Leaving it plugged in after a full charge definitely has negative effects. Although Wuling has a battery management system that automatically stops charging when full to prevent overcharging risks, keeping it plugged in maintains the battery at 100% charge state, which is particularly detrimental to lithium battery aging—it degrades faster under high temperatures, and over time, the battery capacity will drop more quickly. Moreover, leaving it plugged in for too long may pose risks of leakage or short circuits, especially in summer. Once when I was on a business trip for several days without unplugging, I later noticed a decline in battery health. It's advisable to unplug promptly after a full charge, and for daily charging, it's better not to wait until it's fully charged—stopping at 80% is ideal. Developing this habit can also save money, as replacing a battery isn't cheap. Also, pay attention to other equipment in the car, like replacing old plugs promptly if they show signs of wear.
As a long-time owner, the Wuling Mini is affordable and practical, but battery maintenance should not be taken lightly. Leaving it plugged in after a full charge isn't a big issue in the short term because there are protective measures to prevent explosions or overheating, but it can damage battery life in the long run. Lithium batteries experience high internal chemical pressure when fully charged, and maintaining this state for extended periods accelerates electrode aging, potentially leading to reduced range after two or three years. My friend's car suffered from this, eventually costing around a thousand yuan to repair. Additionally, keeping the plug connected continuously may lead to dust and dirt affecting contact, increasing safety risks. It's advisable to set a charging timer or unplug it promptly. Regularly check the battery status via the app. Simple habits like these can extend the car's lifespan to five or six years without issue.
