XPAND XMP Battery Pack
The XPAND Modular Pack (XMP) is the core building block of XALT Energy’s state of the art Energy Storage Systems (ESS) based on XALT Energy’s world class lithium-ion cell designs. XMP is designed for use in multiple applications including hybrid and electric commercial truck, bus and heavy-duty transportation; hybrid and electric marine power and propulsion, rail and mining applications.
Upgradeable, Ultra-Long Lifecycle
XMP core accommodates cells in XALT’s 225mm family without the need for retooling, anticipating a wide variety of application voltage, power, and energy. As cell technologies advance or packs become available for re-purposing, the XMP core can be replaced while all external interfaces remain the same.
Modular and Flexible Design
Easy to customize high voltage, low voltage and cooling interfaces to each application. All connections at front panel; rear access not needed for installation.
Advanced Thermal Management
XMP’s advanced active liquid cooling system maintains ideal cell temperatures throughout the pack and responds quickly to increases in power demand and changes in ambient (environmental) temperatures. Efficient direct liquid cooling prolongs cell life under the most demanding cycle profiles and severe environments, while maintaining full IP67 sealing performance.
XPAND XMOD Battery Pack
The XPAND Module (XMOD) is XALT Energy’s ultra-high-density lithium-ion battery building block for highly integrated Energy Storage Systems (ESS) based on XALT Energy’s world-class lithium-ion cells. XMOD was developed for use in high-voltage, high-capacity multi-module arrays housed in large enclosures to achieve an overall reduction in system mass, volume and cost. XMOD is designed for use in heavy duty transportation vehicles like commercial trucks and buses, as well as rail.
Saving System Cost, Weight and Space
XMOD modules have the same core construction as the exceptionally durable XPAND battery packs, designed to be placed in your enclosure. The XMOD design is optimized for large systems where the integrator installs the modules in a suitable protective enclosure. Eliminating individual pack enclosures saves system weight and allows modules to be packaged very close to each other, resulting in higher energy storage capacity in the available space. Furthermore, with the module arrays enclosed in a protective enclosure, high voltage connections can be made directly to the XMOD terminals, thereby eliminating the need for costly HV connectors and cables.
Upgradeable, Ultra-Long Lifecycle
The XMOD module is designed to accommodate cells in XALT’s 225mm family without the need for retooling, anticipating a wide variety of application voltage, power and energy. This means as XALT’s cell technologies advance or modules become available for re-purposing, the XMOD can be replaced while all external interfaces remain the same.
Advanced Thermal Management
XMOD’s advanced active liquid cooling system maintains ideal cell temperatures throughout the module and responds quickly to increases in power demand and changes in ambient (environmental) temperatures. Efficient direct liquid cooling prolongs cell life under the most demanding cycle profiles, while maintaining reducing packaging volume.
Battery Management System
The BMS is the “brains” of the XMP system providing the monitoring, balancing and safety functionality for the system.
The main job of the BMS is to maintain the lithium-ion cells within their safe operating range regardless of the demands being placed on them. This means the ability to accurately predict operating situations that have the potential for creating over-voltage or under-voltage conditions, as well as high or low temperature conditions – then reacting quickly and safely to prevent those conditions from occurring.
Battery Controls
Battery Disconnect Unit/String Control Unit (BDU/SCU)
The BDU manages individual strings of series-connected XMP subpacks through its on-board String Controller Unit (SCU), pre-charge circuit, current sensor, and contactors. For large XPAND systems of multiple parallel-connected strings, BDUs are connected in parallel.
Master Control Unit (MCU)
The MCU manages multiple parallel strings (up to 24) while providing a single and simple interface to the application controller.
