Power Electronics News: Avoid the Top 3 Issues UPS Designers Encounter when Upgrading to Lithium

Posted on October 28, 2021 by Press Officer

Designing a lithium-based battery backup system for a Telecom or Data Center application presents new and different challenges compared to a traditional VRLA design. Balancing the flow of energy in and out of the battery bank is a critical design parameter. Designers must ensure that power is available under all conditions and optimize the performance of the batteries at the same time. There are 3 main issues designers encounter when designing lithium battery-based systems.

This article presents 3 common issues designers face when making the shift to lithium, and how Green Cubes has developed a patent pending Energy Balance Technology (EBT) to solve these challenges, reduce costs and optimize the use of lithium-ion batteries in UPS applications.

AviationPros: Green Achievements in GSE

Posted on October 19, 2021February 11, 2025 by Press Officer

As several factors across the industry are driving the adoption of electric ground support equipment, many manufacturers are finding success within this segment.

The FAA recently awarded more than $20 million in grants to reduce emissions and improve air quality at airports across the country.

The awards are intended to fund zero-emission airport vehicles as well as electric charging infrastructure and aim to electrify ground support equipment (GSE).

This funding is among the latest initiatives prompting the adoption of electric ground support equipment (eGSE). Environmental goals established by governments, industry organizations, airports, airlines, and individual ground service providers are also lending themselves to eGSE.

With a focus on reducing ground emissions on the ramp, many manufacturers across the market are finding solutions to benefit the GSE industry.

Data Center Dynamics: How Does Temperature Affect Your Choice of Lithium UPS Battery?

Posted on October 14, 2021 by Press Officer

Choose your chemistry wisely, to avoid thermal runaway, and get the performance you need

Industrial rack-mounted uninterruptible power supplies (UPSs) are used in data centers or telecom central offices to provide backup power for servers and switching equipment in the event of failure. Historically, these UPS’s have relied on Lead Acid as the predominant battery type. With the introduction of the Open Compute Project (OCP) initiative and hyperscale data centers, Lithium-ion batteries are gaining market share over the incumbent Lead Acid battery technology.

This article presents some of the thermal considerations and trade-offs when selecting a Lithium-ion UPS system to complement your data center equipment. There are two available chemistry options Lithium Iron Phosphate (LFP) and Lithium Nickel Manganese Cobalt Oxide (NMC). Operators need to consider expected discharge time, active versus passive cooling, options for scalability, and the expected lifetime of the batteries.

Patent Awarded for Green Cubes Technology’s Multi-cell Battery Management Device

Posted on September 8, 2021September 25, 2025 by Press Officer

Green Cubes Technology (Green Cubes), the leader in producing Lithium-ion (Li-ion) power systems that facilitate the transition from lead acid batteries and Internal Combustion Engine (ICE) power to green Lithium-ion (Li-ion) battery power, today announced the patent award for a multi-cell management device for Li-ion batteries. This patent is relevant to industrial motive battery applications, such as material handling and ground support aviation equipment.

These demanding applications require large battery arrays with many Li-ion cells in series and parallel in order to achieve high power and capacity for multi-shift usage. The electronics managing the battery’s communication and safety must enable a robust design that will last for thousands of cycles over many years in harsh conditions.

lithium-battery_nb — With this multi-cell management device, each cell is monitored with a Battery Management Systems (BMS) that measures the voltage of each serial connected cell.

Battery packs consisting of multiple cell lithium batteries can become unstable as the individual cells age and the voltage output from each cell begins to vary with respect to other cells during operation. Balancing the output of individual cells ensures safe operation of the battery system and improves the performance and life expectancy of multi-cell battery packs. With this multi-cell management device, each cell is monitored with a Battery Management Systems (BMS) that measures the voltage of each serial connected cell. Active power control functions balance cell voltage output during charging and discharging operation. With this technology, the elimination of wires and connections to each cell significantly reduces wiring costs and system complexity. The inventors named on patent 11,063,445 are Anthony Cooper of Kokomo, IN, USA and Vasanth Mithilacody of Bangalore, India. For a full description of the patent, read more here.

“Our customers demand the reliability and performance in very demanding use profiles,” said Robin Schneider, Director of Marketing, of Green Cubes. “This new generation BMS with robust cell balancing is designed to last the life of a forklift and is based on a decade of experience and engineering”

As a leader motive power, Green Cubes continues to invent new and better technology. The latest innovations offered in their motive Li-ion batteries include features such as multi-voltage fast charging, dual CANbus communication, and wireless IoT features in addition to continuous improvements such as this new generation BMS with cell balancing for improved reliability.
