DATASHEET: GRID CELL PACK

In energy storage systems, multiple ultracapacitor modules may be used as stand-alone power and energy delivery systems or may be combined with Li-ion or other battery chemistries to create large capacity storage systems with optimized power and energy density. Ultracapacitor storage offers system flexibility by providing rapid power response, footprint optimization, and c-rate management. These attributes are required to meet application demands over a wide range of functions.

Advanced energy storage systems require internal management systems to monitor and maintain safe, reliable

operation of each ultracapacitor pack and to ensure long ultracapacitor lifetime, typically 1,000,000 or more cycles in most grid applications.* The integrated Maxwell Capacitor Management System (CMS) is responsible for cell-to-cell balancing, cell and module voltage, and module temperature monitoring to ensure safe operation. CMS alarms enable shutdown and isolation of racks through CAN or Maxwell HVILTM.

CMS smart cell balancing capability minimizes degradation and power capacity fade. Further, it enables integrators to minimize and control temperature gradients across the system.




Application: Sensitive Loads at Commercial, Industrial, Factory Sites

Commercial and Industrial (C&I) operations often include PLC’s, robotics, computers, lasers, custom machinery controllers and other sensitive electrical and electronic equipment that are unable to tolerate variations in delivered power quality. Disruptions related to power quality issues have a detrimental impact on operation and profit of the enterprise.

To limit these power disturbances, C&I plant owners frequently install generators, fuel cells, or UPS to provide back-up power for various power levels and “ride-through” time durations. Unfortunately, generators and fuel cells often suffer from lack of fast power delivery (measured in cycles for power quality disturbances), high fuel costs, and slow start-up or transfer times resulting in the shutdown and resetting of critical manufacturing and IT equipment. Furthermore, back-upgenerators located on-site may be operated in such a way that they are not always on-line when power disturbances occur.While some large scale UPS systems are available for factory level applications, these come at an extremely high capital expenditure and associated maintenance cost to the factory or plant owner.

An ultracapacitor energy storage system provides fast transition, measured in cycle timeframes, for unexpected, random, and recurring power quality events. Ultracapacitor based solutions address short duration load demand peaks and provide bridge power for the "start-up" of local generators.

Plant owners and operators know that they cannot rely on power grids which suffer from power intermittencies, or be susceptible to disturbances caused by wind, weather, wildlife, effects of tree branches on long distribution lines and other grid power delivery instances that result in unacceptable power quality.

In light of the immediate positive impact on business operations, C&I plant owners can reliably manage their operations by using ultracapacitors or battery-ultracapacitor systems to ensure high and reliable levels of plant operability while minimizing, and in many cases, eliminating vulnerabilities due to power outages.

Maxwell Technologies has the experience to design and optimize C&I power quality solutions across a range of industrial, commercial, and factory applications. Please contact our technical sales team to discuss modeling, simulation, and system level design for your plant or factory.

Commercial and Industrial Ride-Through System with Ultracapacitors



Application: Ultracapacitor Support for Microgrids and Off-Grid Microgrids

Microgrids are deployed as distributed energy resources and operated as a back-up source of power for a critical facility, or deployed within vulnerable utility grid service areas. In either case, microgrids may be operated in an islanded mode.

Microgrids using Battery Energy Storage Systems (BESS) provide valuable functionality such as energy shifting, long duration energy back-up, energy system buffering to load changes, and peak energy shifting. However, power smoothing, voltage and frequency stabilization, fast response to transients, power quality remediation and firming renewable (solar) power must also be performed. These services must be provided while ensuring battery lifetime is preserved over the asset life.

When deploying BESS systems with microgrids, careful evaluation must be given to the battery storage response times, voltage sags, fast transients caused by generator switching and unexpected power quality events.

The addition of solar, or other renewable energy generation to the microgrid, with BESS results in micro-cycling the batteries during daily cloud cover or other atmospheric events.

Ultracapacitors are added to microgrids with BESS, solar or wind and diesel generators in either a DC coupled or AC coupled system architecture. The advantages of DC coupling are lower cost, higher efficiency and ramp rate control. Ramp rate control is often required for solar power smoothing and firming and is frequently required for PV on weak or susceptible utility grid feeders. Additionally, the battery and ultracapacitor system can charge and discharge directly from the grid while maintaining the benefits of DC coupling.

Maxwell Technologies has global experience developing and deploying ultracapacitor solutions for utility and campus microgrids. With our expertise in advanced power modeling and systems design, we can provide optimized microgrid solutions for a wide range of field deployments. Please contact our technical sales and applications engineering team to discuss advanced energy storage solutions for your utility, industrial, campus or defense microgrid.
