On December 4, at the Shanghai Maritime Exhibition, Electric Ship Technology, a subsidiary of CATL, introduced the world's sole 'Ship - Shore - Cloud' integrated zero - carbon shipping and smart port & shipping solution. This innovative offering achieves seamless full - chain integration, spanning from on - board power supply, shore - based energy replenishment, to cloud - based intelligent management.

In the context of the shipping industry, energy replenishment, cost control, and safety have long been significant challenges. CATL's solution effectively tackles these pain points. On the ship side, it integrates batteries, power systems, and intelligent control systems. This integration not only optimizes the ship's power usage but also enhances its overall operational efficiency.

On the shore side, the solution deploys a comprehensive charging and battery - swapping network. Additionally, it adopts a 'ship - electricity separation' model. This model allows for more flexible energy management, enabling ships to quickly replenish energy without being tied to a specific power source on the ship. It significantly reduces the time ships spend on energy replenishment, thus improving the port's operational throughput.

In the cloud, the solution relies on the 'Yunfan' and 'Beichen' platforms. These platforms enable remote monitoring of ships' operational status, including power consumption, battery health, and navigation data. Based on this real - time data, scheduling optimization can be carried out. For example, it can adjust a ship's route or energy replenishment plan according to weather conditions, port congestion, and other factors, ensuring the most efficient and safe operation.

By driving the green transformation of shipping through this solution, CATL is playing a crucial role in reducing carbon emissions in the maritime sector. As of November 2025, CATL has already provided power solutions for nearly 900 electric vessels. This achievement has firmly established CATL as the global leader in the battery supply market for electric ships, setting a new benchmark for the industry.
