Gasgoo Munich- Electric vehicles have gone mainstream, yet fears of battery fires and inflated range claims still linger. While spec sheets for new models often look impressive, consumers remain unsure whether safety guarantees and real-world range can actually be trusted.
To address these market concerns, IM Motors recently teamed up with CATL for a factory tour—skipping the PowerPoint slides to lay bare the manufacturing process, safety protocols, and the reality behind range estimates.

What Ultimately Underpins Battery Safety?
The tour took place at one of CATL’s “Lighthouse Factories” in Ningde. As site officials explained, the “lighthouse” designation isn't about automation for its own sake, but upgrading quality judgment from human intuition to systematic standards. AI-powered defect identification works three times faster than manual checks, reducing rework by roughly 70%. From raw materials to recycling, every step is digitally recorded and fully traceable—meaning the batch, materials, and processing history of any cell can be retrieved instantly.

According to the briefing, a single battery cell passes through roughly 200 processes and 700 quality control nodes from raw material to finished product. The target defect rate on the manufacturing line is set at the PPB level—one part per billion. Behind that number lies a philosophy: safety isn't a matter of luck during spot checks; it’s written into the production line as an input condition from the very first step.

“Safety relies not just on manufacturing, but on design redundancy,” noted Tang Guocheng, CATL’s product manager for domestic passenger vehicles. The upcoming IM LS8 NEO pure electric model, for instance, features a Pyrofuse active fuse: it actively cuts the high-voltage circuit within milliseconds if a collision or thermal runaway risk is detected. The logic is simple—cut the power before the fire starts—adding a critical layer of redundancy for user safety.
Starting July 1, the mandatory national standard GB38031—2025 imposes stricter requirements on battery thermal propagation. “The national standard sets the passing grade, but CATL and IM Motors are building in a buffer above that line,” Tang said.
But that’s far from enough. IM Motors engineers conduct rigorous real-world validation before batteries are installed. From the bitter cold of minus 30 °C in Hailaer to scorching surface temperatures exceeding 50 °C in Turpan, and the continuous uphill climbs of Yulong Snow Mountain, they repeatedly test the stability and adaptability of the thermal management system. This ensures the product is delivered with confidence.

There’s another dimension to safety: IM Motors announced that the new LS8 NEO will exclusively use CATL batteries rather than “self-developed” alternatives. The rationale? Power batteries are patent-intensive and require long validation cycles. Instead of reinventing the cell, it’s better to specialize and collaborate, delivering mature technology directly to users.
That may sound like posturing, but combined with the processes and validation data mentioned earlier, it clarifies who is underwriting safety—the deep vehicle expertise of SAIC combined with CATL’s high-precision R&D team creates a dual technical shield.
How Can Displayed Range Match Real-World Data?
Beyond safety, consumer anxiety stems more from daily use: battery degradation, inflated range claims, incompatible chargers, and winter power loss. Without solving these, even the most impressive spec sheets are meaningless.
Nothing frustrates drivers quite like range estimates that suddenly plummet. On the highway, watching five kilometers of range disappear for every two traveled creates constant anxiety about whether you’ll make it to the next charger.
Asked about the solution, Tang explained that CATL’s new BMS achieves battery estimation accuracy within ±3%, covering over 200 real-world driving scenarios. With that precision, users have a stable expectation of remaining range—no more guessing on every trip. This system is already deployed in the IM LS8 NEO.
Meanwhile, the new BMS employs an industry-first polarization model for power control, predicting available battery power in real time. This boosts discharge power by roughly 20% at low charge levels. In practical terms, even with just 20% charge left, the vehicle retains punch for overtaking and climbing hills—it won't go “soft.”
The BMS also features an “all-weather” design: even after the car is turned off, it continues to collect battery status data at low power, waking up early to issue warnings if anomalies are detected. For users, this means many potential faults are intercepted before they escalate into accidents.
Beyond the new BMS, IM Motors representatives noted that under its NEXT·2028 strategy, the IM NEO tri-electric architecture extends its pursuit of quality to the entire power and energy management system. The NEO Hurricane motor, the new Efficiency Master Management System 3.0, and a full-domain thermal management system together form the core tri-electric technology suite of the IM LS8 NEO.
What Other “Invisible Efforts” Exist Beyond Batteries?
Batteries are just the entry point. The processes, validation, and precision discussed earlier all boil down to one thing: mastering the “invisible work” to earn consumer trust.
Can this logic extend from the battery to the entire vehicle? Judging by IM Motors’ recent launches—especially the upcoming LS8 NEO—the answer is yes.
On the powertrain front, the IM LS8 NEO offers two battery systems: a 103 kWh ternary lithium battery optimized for performance and cold-weather adaptation, and a 93 kWh lithium iron phosphate battery focused on extended range and balance. Both share a full-domain 800V hardware foundation and a dual silicon-carbide platform. Consumers choose based on their driving scenarios rather than being locked into a single option by the manufacturer. Giving users the choice is itself part of quality control—good products should adapt to different conditions, not force users to adapt to the product.
Beyond batteries, the chassis is another system demanding high quality and comfort—one consumers are increasingly watching. IM Motors has introduced steer-by-wire technology, previously seen mostly in million RMB luxury vehicles, into the 250,000 CNY segment. According to Ding Yi, a senior chassis system expert at IM Motors, the new LS8 NEO boasts a turning radius of just 4.85 meters, approaching the agility of an A-segment sedan. It turns full lock in half a circle, solving the pain points of difficult U-turns, tight parking, and heavy low-speed steering in large vehicles. Additionally, IM has developed active anti-roll and run-flat support for high-speed accident scenarios. “Users want the relaxed space of a large five-seater but the agile handling of a small car—that’s the experience a flagship SUV should deliver. The value of a major automaker lies in solving real dilemmas, not making consumers pay for the downsides of body size,” Ding said.

If batteries and chassis are invisible investments, the cabin is the visible magic wand influencing perception and purchasing decisions. To ensure comfort, IM Motors has equipped the new model with natural latex seats, 4D massage functions, and B&O audio. Individually, these aren’t new inventions, but bundling them into a 250,000 CNY family car is. For family users, the cabin is the space they occupy most daily; these “perceivable” experiences build reputation better than stacked specs ever could.
In Conclusion: The Second Half of Competition Is About Stability
The industry is shifting from “fast” to “stable.” Regulations are tightening, with mandatory national standards covering everything from battery thermal propagation to steer-by-wire. Consumers are increasingly willing to pay for certainty and genuine experience. Specs can be marketed, but quality systems, supply chain transparency, and validation cycles—this “invisible work”—will ultimately reveal the truth in public reputation.
True competition has never been about the volume of noise at a launch event, but the ability to satisfy consumer demands with quality and substance. Whoever builds safer products, estimates more accurately, and nails the details will survive the industry shakeout. That was the strongest takeaway from this factory visit: it showed the industry and consumers that quality control isn’t just a slogan, but an engineering system that can be dismantled, inspected, and endorsed by the entire supply chain.
