Ning Service, CATL’s independent aftermarket brand, is offering factory-approved battery repairs to sharply reduce the cost of electric vehicle pack replacements, marking its first anniversary with network and capability expansions on Aug 10.
The company has introduced a cell-to-pack (CTP) repair service that replaces the industry’s “replace-only” approach for damaged packs, particularly after underbody impacts.
Using CATL original parts, OEM procedures and official warranty coverage, the fix is designed to be significantly cheaper than full pack replacement.
Repairs are performed in controlled, dust-free facilities with strict inspection and reassembly protocols to preserve safety and performance.
To accelerate diagnostics, Ning Service has developed a non-destructive testing device that completes battery fault detection in about 15 minutes with over 90% accuracy.
Based on ultrasonic guided-wave technology, it identifies internal damage without disassembly, cutting time and preventing secondary harm. The tool is slated for release by year-end.
The upgrades coincided with “Ning Service Brand Day” and the opening of a Shanghai flagship experience centre and the brand’s first overseas directly operated store in Bangkok, Thailand (over 2,000 sq m).
Ning Service now operates within a global footprint spanning 75 countries with more than 1,100 service outlets and 67 parts warehouses covering over 370,000 sq m. Its service standards target repairs of general faults within eight hours and complex cases within 72 hours, backed by a 24-hour overseas response capability.
Formally spun out as a standalone brand in 2024 from CATL’s after-sales division (founded 2015), Ning Service delivers inspection, maintenance and recycling across passenger cars, commercial vehicles and energy-storage systems.
Its processes are built on 24 industry standards led or co-led by CATL’s after-sales team. Talent development includes professional detection and repair training bases across 18 provinces and municipalities in China, with more than 8,600 specialists trained to date.
The company also advances full-lifecycle management.
A battery health assessment regime aims to identify risks early, extend life and improve transparency for used-vehicle markets. The regime comprises 45 online analyses and 28 offline checks.
Recycling is handled through Brunp Recycling, a CATL subsidiary, via a “72-Hour Express Recycling” network that the firm says delivers triple the regional coverage of third-party platforms.
Retired packs are screened for repair/remanufacture, cascaded to second-life uses or processed for materials recovery.
Ning Service says its expanding service network and repair-first strategy address emerging gaps in EV after-sales support as the market scales, with experience centres now established in seven Chinese cities including Wuhan and Guangzhou, alongside the new Bangkok outlet (shown below).
