The core of safe maritime battery systems
Battery Management System
Our Battery Management System (BMS) is the intelligence behind every Echandia battery system. It ensures safe, stable and predictable operation in all conditions, and is engineered for the demands of heavy-duty maritime use.
Complete control of every cell
The BMS monitors voltage, temperature, state of charge, state of health and capacity across all cells and modules. It keeps the system within safe operating limits at all times and triggers alarms or protective actions when needed. Nothing is left outside supervision. Redundancy in all critical functions.

Built-In Redundancy
Every critical function is duplicated so if one component fails, another immediately takes over, ensuring uninterrupted power and energy delivery with stable digital control signals.
Fault Isolation
Small, repeating modular units confine any fault to a tiny portion of total capacity, minimizing risk and limiting the energy involved.
Serviceable Design
The system can be fully disassembled and reassembled using simple onboard tools, reducing risk during maintenance and repairs.
Long-Life Components
All electrical components are selected for durability, preventing failures caused by wear and tear over time.
Engineered for scale, clarity and integration
The BMS handles very large systems with ease. It delivers clear data summaries and allows multiple strings to operate intelligently as one system. This reduces integration work for customers, even as system size grows.
Critical safety functions are placed lower in the system hierarchy, improving resilience and ensuring continued power delivery even under external disturbances.


Connectable, diagnosable and service-ready
Connecting the battery system makes it possible to access operational data, support the crew, and adjust performance together with the customer. Remote diagnostics and updates reduce downtime and allow faster response. Monitoring of components enables planning of maintenance and improvements that increase availability, safety and system lifetime.
A dedicated Echandia circuit board enables faster and more cost-efficient production of string controls. With improved component availability, we reduce supplier dependency and strengthen delivery security.
