The marine industry is rapidly moving toward electrification as boat manufacturers and operators seek cleaner, quieter, and more efficient propulsion systems.
Unlike traditional automotive applications, marine environments create unique challenges for charging equipment, including water exposure, humidity, vibration, salt corrosion, and limited installation space.
CTS Charger provides advanced marine onboard charger (OBC) solutions designed for electric boats, yachts, ferries, and commercial vessels. Our waterproof and high-efficiency charging systems help marine manufacturers build reliable electric propulsion platforms.
Marine electronic systems must operate reliably under:
- Water exposure
- High humidity
- Salt mist environments
- Temperature changes
Standard chargers often cannot meet these demanding conditions.
Boat designs require compact electrical systems while maintaining sufficient charging power.
Electric vessels typically use large battery packs, requiring stable and efficient charging solutions.
Marine applications often operate in remote locations where equipment failure can create significant downtime.
CTS Charger develops durable and efficient marine OBC solutions engineered for electric vessel applications.
Our marine charging systems provide:
- Waterproof IP67 protection
- High-efficiency AC charging
- Wide voltage compatibility
- CAN communication
- Liquid cooling options
- Parallel charging capability
CTS OBC products can be customized according to vessel battery systems, charging requirements, and installation environments.
