MG Energy Systems announces DNV GL certification for RS battery system

LinkedIn +

MG Energy Systems, the battery manufacturer for marine applications, has announced that its RS battery system has passed DNV GL type approval and now complies with rules for ships, offshore units, plus high-speed and light crafts. The RS battery system is now accepted for installation on all vessels that require DNV GL classification.

The RS battery system is a liquid-cooled lithium-ion, battery-based energy storage system (ESS) for use in battery-powered or hybrid vessels and offshore units. The system is designed with a unique propagation protection system (PPS) that ensures there is no thermal runaway propagation between cells within a module.

The RS battery is ready to be installed with an integrated off-gas duct. The system consists of MG RS battery modules and two variants of the MG master HV battery management system (Master BMS).

One single RS battery module consists of up to 48 battery cells. Each individual RS battery module contains its own slave and redundant BMS. The battery modules can be connected in series or in parallel to meet the required system voltage and capacity. The possible voltage range for a single string is from 44V DC up to 900V DC. When larger battery banks are needed, multiple strings can be connected in parallel to increase the capacity.
