Capabilities
Capability Matrix
Where the company does the work itself, and where it depends on a third party. Each entry cites what the supplier published.
| Dimension | Capability | Evidence |
|---|---|---|
| Hardware Design | In-house | The official About page says the company conducts power-technology R&D and provides customized solutions, while its product portfolio includes substations, transformers, GIS, breakers, protection, monitoring and vehicle electrical equipment (official website). |
| Firmware | Partial | The 2024 Sustainability Report identifies group companies classified as software development, including 上海源胧软件有限公司, 江苏智源科技有限公司 and 北京思源清能电气电子有限公司. This supports in-house control-software development, but the provided sources do not specifically establish ownership of all embedded MCU firmware, so the capability is classified as partial. |
| Manufacturing | In-house | The company describes itself as conducting equipment manufacturing and operating multiple industrial-manufacturing subsidiaries; the 2025 Sustainability Report identifies manufacturing locations and seven national-level green factories. |
| Cloud / App | No | The provided sources describe automation, monitoring and intelligent operation-and-maintenance products, but do not publish evidence of an independently developed consumer cloud or mobile application. |
