Key Points
- The China Association of Automobile Manufacturers (CAAM) officially denied rumors that New Energy Vehicle (NEV) companies were being investigated for “battery locking.”
- “Battery locking” involves manufacturers using OTA updates to restrict battery functions, such as limiting capacity or charging speed, often without explicit consumer notification.
- CAAM emphasized that all official regulatory information comes from government sources and urged the industry to prioritize transparency.
- The association called for NEV manufacturers to maintain information transparency, protect consumer rights, and resolve disputes related to battery capacity limits to safeguard brand reputation.
- Clarification: Denied rumors of NEV investigations regarding “battery locking.”
- Source Verification: Official regulatory info must come from government sources.
- Industry Call to Action: Focus on transparency, consumer rights, and dispute resolution.
The China Association of Automobile Manufacturers (Zhongguo Qiche Gongye Xiehui 中国汽车工业协会), also known as CAAM, just dropped a major clarification.
On May 9th, they came out swinging against viral rumors claiming that New Energy Vehicle (NEV) companies were being investigated for “battery locking” practices.
Their statement was crystal clear: these reports are completely false.
What Were The Rumors Claiming?
Online chatter had suggested some pretty wild allegations:
- Eight NEV companies were supposedly summoned for regulatory talks
- Three companies faced formal investigations
- All of this was allegedly tied to “battery locking” issues
The problem? None of it had any official source.
According to a relevant official from CAAM, these claims were “seriously inconsistent with the facts.”

Understanding “Battery Locking” In The EV Space
Before we dig deeper, let’s break down what “battery locking” actually means in the context of electric vehicles.
This practice typically involves manufacturers using Over-the-Air (OTA) updates to restrict certain battery functions:
- Limiting usable battery capacity via software
- Reducing maximum charging speed
- Preventing the battery from operating at full potential
Manufacturers often justify this by claiming they’re:
- Preventing battery overheating
- Extending the lifespan of older battery cells
- Protecting vehicle longevity
The controversy? Consumers often aren’t explicitly told about these restrictions beforehand.

CAAM’s Official Response: Here’s What Really Matters
CAAM emphasized something crucial for anyone following this space:
All industry regulatory updates and enforcement measures must come from official government sources.
Translation: if you’re seeing rumors without official backing, take them with a grain of salt.
The association made it clear that unverified claims circulating online shouldn’t be treated as fact, especially when they could impact investor confidence and brand reputation across the NEV sector.

What CAAM Actually Wants NEV Companies To Do
While dismissing the investigation rumors, CAAM didn’t shy away from calling out what they think needs to happen in the industry:
Transparency First
NEV manufacturers need to maintain information transparency while optimizing their Battery Management Systems (BMS).
This means being honest about what’s happening under the hood—literally.
Consumer Rights Matter
The association emphasized that companies must:
- Protect consumers’ right to be informed
- Respect consumers’ right to choose
- Establish clear after-sales communication channels
- Actively resolve complaints and disputes related to battery capacity limits
Reputation Is Everything
Here’s the bottom line: maintaining honest operations is essential to safeguarding brand reputation.
In a rapidly growing market like China’s EV space, trust is currency.
One scandal can tank brand loyalty faster than a smartphone losing battery at 1%.

Why This Matters For The EV Industry Right Now
The NEV market in China is absolutely booming.
Competition is fierce between established players and emerging startups, which means:
- Any negative headline spreads like wildfire on social media
- Consumer trust is fragile and hard to rebuild once broken
- Regulatory scrutiny is increasing as the market matures
- Misinformation can have real consequences for stock prices and sales
CAAM’s push for transparency isn’t just about ethics—it’s about protecting the entire industry’s credibility.

The Bigger Picture
This clarification highlights an interesting dynamic in China’s tech and automotive sectors:
- Rumors spread fast, facts spread slower
- Without official verification, claims should be treated skeptically
- Industry associations are stepping up to combat misinformation
- Consumer protection and transparency are becoming table stakes
For investors, founders, and market watchers, the takeaway is straightforward: always verify through official channels before making decisions based on unconfirmed reports.
The “battery locking” debate in China’s EV market will likely continue, but at least now we know what’s actually been investigated versus what’s just noise.
