What size wire is needed for charging the Wuling Mini?

[PeterLee]

The Wuling Mini requires a 4-square millimeter wire for charging. Below is the relevant information: 1. Home power supply: As a four-seat new energy vehicle, the Wuling Hongguang MINIEV can be directly charged using a standard household grounded 220V three-pin power supply, with a charging power of less than 2kW. The Hongguang MINIEV does not rely on charging piles and comes equipped with an integrated high-efficiency charging cable. The 120KM range model takes about 6 hours to charge, while the 170KM range model takes approximately 9 hours, making it very convenient. 2. Battery introduction: The Hongguang MINIEV battery features low-temperature pre-heating charging technology, battery insulation function, and an intelligent battery management system (BMS), which allows real-time monitoring of the battery status, facilitating charging and power usage monitoring.

As a long-time owner of the Wuling MINI, I've been using a 2.5 square millimeter copper wire for charging, and it's proven to be quite reliable in practice. I've heard some say that a 1.5 square millimeter wire can barely manage, but last summer when I touched the wire's insulation during charging and found it uncomfortably hot, I immediately switched to a thicker one. Now, the entire charging line stays just warm when fully charged. I've also installed a dedicated 16A socket on the garage wall, paired with the original charging gun, so overheating is no longer a concern. A word of advice: always opt for pure copper wires and don't skimp by buying aluminum ones. It's also best to avoid using extension cords. I've seen a neighbor's charger overheat and trip due to a poor-quality extension cable—safety should always come first.

I'm an electrician and have installed many new energy charging circuits for customers. The Wuling MINI has a charging power of about 1.6kW, theoretically a 1.5 square millimeter national standard copper wire is sufficient. However, it is practically recommended to use 2.5 square millimeter wires to reserve a safety margin of over 1500W. Pay special attention to the length of the circuit: if the distance from the meter to the socket exceeds 30 meters, a 4 square millimeter wire is needed to meet the voltage drop standards. An independent leakage protection switch must be installed, and never pull wires from an air conditioning socket. Last month during an inspection, I found a household using 1.5 square millimeter wires had their plug melted and deformed. It's better to use a larger wire size than a smaller one; safety redundancy is crucial.

When my friend first bought the Wuling Hongguang MINIEV, they directly used an air-conditioning socket for charging, but the charger kept shutting off automatically. After inspection, it was found that the 1 square millimeter aging aluminum wire couldn't handle the load, causing the voltage to drop to 190V during charging. Now, they've replaced it with a 2.5 square millimeter national standard copper wire, running a dedicated line less than 20 meters from the meter, paired with a Chint 32A leakage protection switch. During charging, a clamp meter showed a stable current of 8A, with the wire insulation temperature around 40°C. For new homes with shorter wiring, 1.5 square millimeter might barely suffice; for older houses with wiring over 15 meters, 2.5 square millimeter is necessary.
