What to Do If the Wuling Hongguang Mini Has No Ground Wire for Charging?

The Wuling Hongguang Mini can be charged using a charging station or household electricity if it lacks a ground wire. Below are the specific details about the Wuling Hongguang Mini: 1. The Wuling Hongguang Mini is a micro-sized pure electric vehicle with the battery located beneath the chassis. It can be charged using a standard 220V three-pin household power supply with a ground wire, with a charging power of less than 2kW. The charging time is approximately 6 to 9 hours. 2. The Wuling Hongguang Mini features a 2+2 four-seat layout, accommodating four adults. The front seats are adjustable in terms of position and backrest angle, while the rear seats support a 50:50 split-folding function. It comes equipped with features such as brake force distribution, ABS anti-lock braking system, tire pressure monitoring, child seat anchors, seatbelt reminder, parking sensors, hill start assist, aluminum alloy wheels, a full LCD instrument panel, power windows, and remote door locks. 3. The vehicle is powered by lithium-ion batteries across all models, offering slightly better reliability compared to lithium carbonate batteries.
When I drove the Hongguang Mini before, I also encountered the issue of no ground wire for charging. Later, I found a temporary solution by purchasing a grounding adapter, which costs around 200 yuan. Plugging it in allows the charger to detect a simulated ground signal. However, after using it for two months, I still hired an electrician to install a proper ground wire in my garage, as the grounding adapter is only an emergency solution and poses safety risks for long-term use. By the way, when there's no ground wire, the charging panel will show a red light indicating a fault. Under no circumstances should you force charging at this time, as it can easily damage the charging module. If the residential circuit is too old to add a ground wire, it's advisable to charge up to 90% at night and unplug it, avoiding overnight charging.
Not having a ground wire in the old house for charging is indeed quite troublesome. Last time, I directly called the property electrician to take a look. The experienced electrician tested the circuit with a voltage tester and suggested either renovating the garage wiring to add a grounding device, which would cost about four to five hundred, or using public charging stations at nearby shopping malls. Later, I chose the latter option—though a bit more inconvenient, it's safer and more reliable. I remember once charging on a rainy day when the plug suddenly sparked, which was caused by the lack of a ground wire. Now, I always carry a portable charger with me and switch locations if I find an outlet without a proper ground wire. EV owners should always keep a circuit tester handy to check outlet safety before each charging session.
After driving the Hongguang Mini for half a year, I discovered the charging issue lies in the power socket. Last time when I returned to my hometown and used a regular socket for charging, the dashboard directly displayed a grounding fault. The temporary solution was purchasing a grounding converter online, which is about the size of a phone charger and can be connected for charging. However, the converter tends to heat up after prolonged use, so I always move a small stool to sit beside it and monitor, unplugging after two hours of charging. Later, I applied to the power supply bureau for a separate meter and installed a dedicated circuit with a ground wire for the garage. If you don’t want to modify the circuit temporarily, it’s advisable to charge during cool and dry periods, avoiding rainy or high-temperature days.
