High Voltage – High Energy NMC Packs
01. High Energy Density
02. Lightweight & Compact
03. Scalable up to 1,000 V
Marine battery
High energy. Low weight.
Lightweight design
Lightweight design with 3.7 V nominal Li-NMC cells. 5.6 kg/kWh at module level
Lower cell impedance
Low internal resistance for higher efficiency and improved power performance.
Dual-core lockstep CPU BMS
Ensures redundancy and continuous
monitoring, HVIL & internal coolant-leak detection.
Designed to limit fire propagation
Fire-resistant materials and internal isolation measures are designed and demonstrated to limit propagation. RINA testing successfully demonstrated no propagation between cells, with DNV Type Approval currently in progress.
Remote data monitoring
Access complete system data remotely to reduce downtime and optimise performance. Advanced State of Charge (SoC) and State of Health (SoH).
Scalable high-voltage architecture
Designed for larger electric and hybrid propulsion systems, with a scalable high-voltage architecture of up to 1000 V. Self-stackable or rack-mounted.
Flexible pack configurations
Smaller pack configurations are available on request, offering approximately 50% capacity in around 60% of the standard pack length for installations where space is limited.
Module-level protection
Hardware override switch and a separate fuse for each module.
Proven marine reliability
Thousands of modules have been in operation since 2022 with no recorded failures, providing a proven platform for demanding marine applications.
