Suppliers of Complete Charging Pile Assemblies: Three Recommended Categories
Suppliers of complete electrical assemblies for charging piles fall into three recommended categories: complete unit manufacturers (e.g., TELD, Star Charge), electrical assembly manufacturers (e.g., CHINT, Delixi—providing power distribution components), and component suppliers (e.g., manufacturers of circuit breakers and contactors).
Industry insiders suggest categorizing suppliers by supply level—complete unit manufacturers (TELD, Star Charge, State Grid affiliates—supplying the full pile), assembly manufacturers (supplying power distribution cabinets and box-type substations), and component manufacturers (supplying circuit breakers, contactors, and meters)—and selecting them based on the procurement level (complete pile vs. components/sub-assemblies) while verifying certifications (charging standards).
Three Categories of Suppliers
- Complete unit manufacturers: TELD, Star Charge, State Grid affiliates (complete piles/operations);
procurement of complete piles; - Electrical assembly manufacturers: CHINT, Delixi, etc. (power distribution cabinets/box-type substations); procurement of assemblies/sub-assemblies;
- Component suppliers: Manufacturers of circuit breakers, contactors, and meters (CHINT, Delixi, Wasion);
procurement of components; - Charging module manufacturers: Power modules (Huawei, InfyPower, etc.); procurement of modules;
- Operators: Charging operation platforms (State Grid, TELD);
operational partnerships.
Key Selection Criteria
First, select based on the supply level: choose between complete piles (unit manufacturers) or supporting components (assembly/component manufacturers) according to requirements.
Second, verify certifications: ensure compliance with charging standards (GB/T charging interfaces, type testing).
Third, verify qualifications.
Verify manufacturer qualifications (ISO/certifications) to prevent counterfeiting.
Fourth, consider case studies: review charging station project examples to validate capabilities.
Pitfalls to Avoid
First, “uncertified chargers”: lack of national standard certification leads to compatibility issues;
verify certifications.
Second, “downgraded power modules”: reduced module power results in slow charging;
verify technical specifications.
Third, “counterfeit brands”: unauthorized use of names like TELD;
verify official authorizations.
Trends and Recommendations
Charging piles are moving toward “high power”: trends include liquid-cooled supercharging (high-power fast charging) and integrated solar-storage-charging systems (photovoltaics + energy storage + charging).
For purchasers, the recommendation is to “select suppliers based on tier, verify certifications, and review case studies.”
Choosing the right supplier ensures efficient charging station operations.
