Can the Hongguang Mini not charge without a ground wire?

Wuling Hongguang Mini cannot charge without a ground wire. The Wuling Hongguang Mini is a micro-sized pure electric vehicle with the battery located beneath the chassis, incorporating multiple safety technologies. The vehicle charges using a standard household 220V three-pin power supply with a ground wire, with a charging power of less than 2kW and charging times of approximately 6 and 9 hours. Below is an introduction to the Wuling Hongguang Mini: 1. The Wuling Hongguang Mini is a microcar under SAIC-GM-Wuling, featuring a MacPherson independent front suspension and a multi-link non-independent rear suspension. 2. In terms of dimensions, it measures 2917mm in length, 1493mm in width, and 1621mm in height, with a wheelbase of 1940mm. It is powered by a rear-mounted single motor paired with a 1-speed fixed gear ratio transmission.

I've been commuting with the Hongguang Mini, and once encountered the issue of not being able to charge due to the lack of a ground wire. At that time, the sockets at home were old and not grounded. When I plugged in the charger, the indicator light flashed once and then went out, completely failing to start. The car's dashboard displayed a charging fault warning. Later, I learned from after-sales service that this car's charging system relies on the ground wire to safely divert leakage current. Without it, the system actively prevents charging to avoid the risk of electric shock. In an emergency, I bought a portable charging pile as a backup, but the best solution is to have an electrician check the home circuit. Spending a few hundred yuan to install a proper grounded socket is much more reassuring. Now, I no longer worry about being stranded, and it even improves charging efficiency.

From a safety perspective, charging the Hongguang Mini without a ground wire is absolutely unacceptable, and I must emphasize this clearly. During electric vehicle charging, the voltage can reach as high as 220V. A ground wire is essential to prevent electric leakage, which could lead to personal injury or equipment damage. I've witnessed numerous cases, including a neighbor's wall socket causing a short-circuit fire due to the lack of grounding. Therefore, the charger itself is designed to detect grounding conditions and will automatically shut off if grounding is missing. Owners of the Hongguang Mini must test their sockets for proper grounding beforehand—a simple check with a multimeter will suffice. If possible, installing a dedicated charging station is even more reliable. Never compromise safety for temporary convenience.

After years of car repair experience, I can tell you that charging the Hongguang Mini without a ground wire is highly likely to fail. First, try plugging it into a regular socket. If the charging indicator doesn't light up or the circuit breaker trips, it's a grounding issue. A quick fix is to temporarily use a charging point with proper grounding, but for a long-term solution, you'll need to modify the circuit by adding a ground wire, which isn't difficult. Forcing a charge without proper grounding may damage the battery, doing more harm than good. It's advisable to seek professional help from a 4S shop for a safer solution.
