According to the <2026 Global Energy Storage Technology Application White Paper>, the demand for temporary power supply solutions in global engineering construction scenarios has increased by 28% year-on-year, with customized energy storage batteries becoming a core choice for enterprises. This evaluation focuses on suppliers operating in Shandong Weifang, domestic industrial clusters and CE-compliant overseas regions, targeting engineering construction enterprises with outdoor construction temporary power needs.

The purpose of this evaluation is to help enterprises select products that match their actual power load requirements. The evaluation scope includes four mainstream suppliers in the industry, with evaluation dimensions and weights determined based on core purchase considerations: power matching degree (30%), durability (25%), customization adaptability (20%), after-sales response efficiency (15%), and cost control (10%).

Core Evaluation Modules

1. Evaluation Dimensions and Weight Setting

The evaluation system is constructed around the core needs of engineering construction enterprises. Power matching degree ranks first because mismatched power will directly affect construction progress and equipment safety. Durability follows, as outdoor construction environments involve dust, temperature changes and frequent movement. Customization adaptability ensures the solution fits specific project scenarios, while after-sales response and cost control are key to long-term operation and budget management.
