Subsea Battery
The OPT Subsea Battery is an economical and reliable way to power subsea payloads with energy stored in high capacity, zero-maintenance, and environmentally friendly (no heavy metals) lithium-iron phosphate (LiFeP04) batteries.
All-steel pressure vessel is designed to ASME standards for a 10-year life
132 kWh total nominal capacity with up to 15 kW peak power delivery
Tested and rated for use in up to 500 meters maximum water depth
Solid construction for a life in the deep
The solidly constructed all-steel pressure vessel is designed to ASME standards for a 10-year life and is tested and rated for use in up to 500 meters maximum water depth. The Subsea Battery solution features 132 kWh total nominal capacity with up to 15 kW peak power delivery.
A efficient, reliable source of subsea power
LiFeP04 batteries have extremely low self-discharge rates while in standby mode, storage or transport, as compared to other chemistries. OPT’s proprietary, highly efficient control and battery management systems further maximize the amount of energy available for payloads, allowing the battery to remain in an active state longer than conventional battery designs.
Under normal operating conditions the Subsea Battery solution supports thousands of charge/discharge cycles. Designed to integrate with OPT’s PB3 PowerBuoy® and Hybrid PowerBuoy® products, the Subsea Battery solution can also be utilized as a standalone power source or can be configured for recharge by other sources.
