How should I choose a robot battery manufacturer?

Choosing a reliable lithium battery manufacturer for robots hinges on several key factors: application scenario requirements, batch size, safety certifications, customization capabilities, and after-sales support. You can assess this based on the following:

• First, clearly define your robot's application scenario and operating conditions. Is it an indoor AGV, outdoor inspection robot, humanoid robot, or explosion-proof special scenario? Requirements such as heavy load, high and low temperature operation, waterproofing, fast charging, and high-rate discharge directly determine the cell type and pack solution. Prioritize manufacturers with mature case studies in the corresponding scenarios, avoiding the use of general-purpose power batteries for special operating conditions.
• Next, consider order batch size and customized development models. For large-volume standardized models, prioritize leading manufacturers like CATL, Guoxuan, and Zhongchuang Xinhang, as they offer low costs, stable delivery, and consistent quality. For small-batch, non-standard customized robots, robots with irregular structures, or robots requiring rapid iteration, it's more suitable to find manufacturers like Yuye New Energy and Xinengan that support flexible customization and can collaborate on structural, BMS communication, and interface protocol development.
• Focus on verifying safety and certification systems. Industrial and commercial robots should at least have basic certifications such as UN38.3, CE, and UL. Explosion-proof certification is also required for applications in chemical, mining, and inspection sectors. It's also crucial to check if the manufacturer offers comprehensive thermal runaway protection, overcharge and over-discharge protection, and shock and vibration resistance design; don't just look at specifications and ignore actual safety redundancy.
• Finally, compare technical support and long-term service capabilities. Reliable manufacturers not only provide battery packs but also BMS protocol integration, thermal management recommendations, aging tests, after-sales warranty, and mass production iteration solutions. The stability of long-term supply and the speed of fault response directly impact the robot's subsequent mass production and maintenance costs.

• 2. Customized Solution Design (2-7 business days): Repeated discussions with the client on details until both parties confirm the final version of the robot battery solution.
• 3. Contract Signing and Sample Delivery (3-7 business days): All tests are completed before shipment, samples are sent, and testing guidance is provided. The client signs a sample confirmation form after completing on-site verification.
• 4. Mass Production and Quality Control (25-30 business days): From preparing materials for mass production (15 business days) to standardized production (implementing full-process process control), and finally, full inspection of finished products before shipment.
• 5. After-Sales Maintenance: Providing technical support and after-sales service.
