The intelligent battery swap recommendation (BSRec) system for e-bikes is a critical need in the development of smart urban transportation. However, challenges such as limited observable data and the complexity of cabinet-battery constraints have hindered model generalization across multiple tasks. In this paper, we propose eBASE, the first model for e-bike BSRec, which integrates a hybrid expert system with dual-tower joint optimization. Experimental results show that eBASE outperforms existing models in three real-world tasks: cabinet, battery, and cabinet-battery recommendations. Additionally, the BSRec system developed with eBASE has been deployed in over 10 cities, significantly improving the multi-dimensional satisfaction of millions of riders.

摘要

The intelligent battery swap recommendation (BSRec) system for e-bikes is a critical need in the development of smart urban transportation. However, challenges such as limited observable data and the complexity of cabinet-battery constraints have hindered model generalization across multiple tasks. In this paper, we propose eBASE, the first model for e-bike BSRec, which integrates a hybrid expert system with dual-tower joint optimization. Experimental results show that eBASE outperforms existing models in three real-world tasks: cabinet, battery, and cabinet-battery recommendations. Additionally, the BSRec system developed with eBASE has been deployed in over 10 cities, significantly improving the multi-dimensional satisfaction of millions of riders.
