Underwater Lithium Batteries for Ships, Yachts, Unmanned Vessels, etc.
1、Industry Background
In a global context, the new energy industry is emerging as a critical force driving economic growth and realizing green transition, leading a profound industrial revolution. At the opening ceremony of the previous Paris Olympics, 31 electric yachts carrying athletes from various countries made their debut on the Seine River. This ceremony was not only a historic moment for the Olympics but also foreshadowed the new trend of green and intelligent development in the shipping industry.
Driven by the global environmental protection trend and energy transition, China's new energy marine industry is embracing unprecedented development opportunities. With continuous technological innovation and breakthroughs—particularly the improvement of battery energy density, optimization of power systems, and application of intelligent technologies—the performance and competitiveness of new energy vessels have significantly enhanced.
In 2024, the General Office of the Guangdong Provincial People's Government officially promulgated the Notice on Issuing the Action Plan for Promoting High-Quality Development of Guangdong's Yacht Industry (2024-2027). Concurrently, the government has rolled out a suite of policy incentives and subsidy mechanisms, providing robust institutional safeguards for the advancement of new energy marine vessels.
2、Demand Pain Points
Insufficient Range and Power
Traditional lead-acid batteries previously used have low energy density, large volume, and heavy weight, severely restricting space utilization. They fail to meet the long-duration, high-speed navigation requirements of ships/yachts, limiting their operational range and speed performance on water.
Lack of Communication and Intelligence
The absence of convenient communication functions and customized charging protocols hinders real-time battery status monitoring and intelligent management, failing to satisfy the intelligent requirements of modern high-end water sports equipment for batteries.
3、Technical Solutions
Guihang tackles customers' pain points by optimizing and customizing the material system—including ternary lithium or lithium iron phosphate cells, BMS, casings, connectors, protection ratings, etc.—in strict alignment with their application requirements.
Taking this case as an example:
Dimensions: 1170×790×400 mm
Nominal voltage: 96V
Nominal capacity: 400Ah
Energy: 38.4 kWh
Operating current: 400A
Maximum discharge current: 600A (sustained for 30 seconds)
In contrast, traditional lead-acid batteries have low energy density, storing less power for the same volume, and are limited in discharge current—making it difficult to support long-duration high-speed navigation for ships/yachts. This drive battery provides customers' vessels with powerful and stable power output, ensuring high-speed water navigation. Meanwhile, its ample power capacity guarantees long range, meeting users' high-energy demands for prolonged water sports.
Lighter Weight
The thruster lithium battery weighs 300KG. While ensuring high energy density, it achieves lightweight design through advanced materials and processes. Due to the material characteristics of traditional lead-acid batteries, their weight is often heavier for the same power capacity, increasing the load on ships/yachts and affecting their flexibility and maneuverability. This product effectively reduces the burden on vessels.
Significant Performance Improvement
The yacht's range has increased by 50%, far exceeding traditional lead-acid batteries in both power performance and endurance. This has attracted the attention of numerous water sports enthusiasts and significantly enhanced the product's market competitiveness.
Outstanding Intelligent Advantages
Equipped with 485/CAN custom communication functions, it supports real-time monitoring of battery parameters such as voltage, current, and charge level. The advanced communication and intelligent features enable users to grasp the battery status in real time, achieving refined management of the battery. Meanwhile, the customized charging protocols and Bluetooth functions make the charging process more intelligent and convenient, improving the overall user experience and adding unique selling points to customers' products. In contrast, traditional lead-acid batteries hardly have intelligent communication functions, unable to monitor battery status in real time, and lack intelligent management during charging, leading to extremely inconvenient use.
