Battery system specialist XALT Energy has unveiled its XRS XPAND Rack system, which combines the company’s XPAND Battery System with its proprietary battery management system (BMS). These products have received DNV GL Type Approvals, which means that they can be installed in vessels classified by maritime registrar DNV GL. The modular systems also show promise for transit bus and heavy-duty truck applications.
The XPAND Rack operates at up to 1,000 V and can provide up to 222 kWh of energy, depending on the chosen configuration. Plumbing, ducting, and high-voltage distribution components are paired with liquid cooling to increase product performance and lifespan. Also, the systems were required to pass a forced thermal runaway passive propagation requirement with “no active safety systems required.” This makes them compliant with the Norwegian Maritime Authority’s (NMA) Propagation test 1.
“The safety, durability, and flexibility of XALT’s XPAND-based systems have been recognized by commercial transit bus and heavy-duty truck customers worldwide,” says XALT’s Senior VP of Engineering Martin Klein. “Now XRS opens the door for deployment on very large marine vessels. Given the ability to populate XRS with XALT’s high-energy or high-power XPAND packs, we are able to fulfill a wide range of marine missions, including ferries, tugboats, and off-shore support ships.”
