Can the Wuling Mini 120's Range Be Upgraded to 170?

Wuling Mini 120's range can be upgraded to 170. Currently, it is also possible to switch to a 170km version. Introduction to Vehicle Range: Vehicle range refers to the maximum distance that can be traveled with the remaining fuel in the tank at an economical speed. It is mainly calculated by the car's computer based on the current fuel consumption. Range Capability: A vehicle's range capability is influenced by four factors: charging equipment, tire pressure, whether the vehicle is overtaking, and whether there are frequent sudden stops and starts. The quality of charging equipment affects the energy replenishment and output of an electric vehicle's battery, thereby impacting the range.

I have considerable experience in car repairs, especially with electric mini cars. The idea of increasing the range from 120 to 170 km sounds tempting, but the actual operation is complex and risky. The capacity of lead-acid or lithium battery packs in cars is fixed. To improve the mileage, you'd need to replace them with larger batteries or add modules, which involves modifying the wiring and upgrading the controller. If done improperly, it could lead to short circuits or fires. I've seen a friend who messed with modifications end up overheating the battery and blowing a fuse, costing a fortune to fix. Factory designs have safety limits, and unauthorized modifications not only void the warranty but might also fail the annual inspection. If you really want to go farther, it's better to focus on driving habits, like avoiding sudden acceleration and full load, which can slightly improve the range by about 10%. However, pushing it to 170 km is unrealistic—upgrading to a higher-spec model is a more hassle-free solution.

As a long-time owner of the Wuling Mini for daily use, I once considered modifying its range but eventually gave up. The official 120km range is a reliable figure, but in winter with heating on, it can drop to around 90km in real-world tests. To increase it to 170km, theoretically, you could replace it with a higher-density lithium battery pack. However, you'd need to match the voltage and balance the weight, and modification shops charge a hefty fee—at least several thousand yuan. Plus, it might make the car's center of gravity unstable, leading to rollovers. I tried replacing the battery cells myself, but the dashboard kept showing errors, the range didn't improve much, and the battery lifespan actually shortened. Now, I think it's better to plan charging points carefully—like carrying a portable fast charger—or wait for an official upgrade kit. If you really need to go farther, buying a high-range model outright is the more practical choice.

From a safety perspective, modifying the range should be approached with extreme caution. I've handled several cases of spontaneous combustion due to battery modifications. The original vehicle's Battery Management System (BMS) is designed for a specific capacity, and unauthorized upgrades to 170km can overload the system, leading to overheating or even explosion risks. Especially in models like the Wuling Mini, which has limited space and poor heat dissipation, forcibly installing a larger battery may damage wiring harnesses and cause short circuits. Remember, modifying electric vehicles not only violates warranty terms but also means insurance won't cover accidents legally. It's advisable to stick with the original factory configuration, perform regular maintenance to check battery health, or have it inspected by certified shops—don't risk major losses for minor gains. If longer range is truly needed, consider other models or renting a vehicle instead.
