CTS 96V 300Ah LiFePO4 Battery for Solar-Electric Yachts in Europe

Case Study: High-Voltage Lithium Battery System for Premium European Solar-Electric Yachts

Project Overview

• Client Profile: A pioneering European innovator specializing in high-end solar-electric maritime mobility and sustainable vessel design.
• Target Application: All-electric luxury day-boats and solar-integrated cruisers.
• System Configuration: Dual-Pack Architecture ($2\times$ 96V 300Ah LiFePO4 units) per vessel.
• Key Hardware: External PDU (Power Distribution Unit) housed in SUS316 Stainless Steel.
• Core Objective: To provide a high-energy-density, marine-grade power source that seamlessly integrates with solar charging for a silent, zero-emission cruising experience.

The Challenge

The client sought an energy solution that could meet the rigorous demands of offshore environments while upholding their brand promise of "Total Silence and Sustainable Luxury." Key requirements included:

1. High Voltage Stability: A stable 96V platform for consistent electric propulsion.
2. Solar Synergy: Efficiently handling variable charge currents from integrated solar arrays.
3. Marine Durability: Absolute protection against high humidity, salt spray, and continuous seawater exposure.

The Solution: Dual 96V 300Ah System with Marine-Grade External Distribution

We provided a comprehensive power solution that combines high-output lithium technology with a heavy-duty, modular distribution framework.

Key Technical Features:

• Centralized External PDU: To optimize engine room layout and simplify maintenance, the system utilizes a standalone external PDU. This centralized unit manages the power merging from both 96V packs, directing it to the propulsion motors and integrating the solar charging inputs. It features high-spec internal contactors, fuses, and emergency disconnects for maximum electrical safety.
• Dual-Pack Redundancy: By utilizing two independent 96V 300Ah units, the vessel benefits from a redundant power architecture. This ensures that even in the unlikely event of a single pack shutdown, the yacht maintains enough power to return safely to shore.
• SUS316 Marine-Grade Stainless Steel: Both the battery enclosures and the external PDU housing are crafted from SUS316 stainless steel. Recognized as the gold standard for maritime hardware, SUS316 offers superior resistance to pitting and crevice corrosion caused by chloride-rich seawater, significantly outperforming standard alloys.
• IP67 Waterproofing & Seal Integrity: The entire system is rated at IP67, ensuring total protection against temporary immersion and the high-humidity, high-salt maritime atmosphere.
