Battcon ’21 Attendees Impressed with Green Cube’s (formerly branded as UNIPOWER) Guardian and Aspiro DC Power Systems

Posted on November 22, 2021 by Press Officer

At this year’s Battcon conference, we were pleased to present our highly trusted and reliable Guardian and Aspiro DC power families. Conversations were a plenty about the reliability and technology of power systems and how lithium-ion batteries are becoming favored for utility and telecom applications compared to lead-acid batteries. Lithium-ion chemistry has a distinct advantage over lead-acid as it offers batteries with higher energy densities and longer lifetimes that are smaller and significantly lighter in weight.

Our Guardian and Aspiro product lines can operate with a variety of battery chemistries — including lithium-ion, like the new Guardian Lithium batteries from Green Cubes — to provide clean, reliable, safe DC power when AC grid power is lost. Each Guardian battery contains an integrated Battery Management System (BMS), charging electronics, and proprietary Energy Balancing Technology (EBT) that enables active current control, load sharing and State of Charge balancing across connected units. This is a significant advantage for users as lead-acid battery monitoring systems typically must be purchased from a third party and integrated into their battery installation.

All Guardian batteries have active thermal management and feature Lithium Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LFP) chemistries to accommodate multiple utility and telecom applications. Having the BMS built into the batteries allows considerable cost saving for operators. Also, with increasingly strict requirements from the North American Electric Reliability Corporation (NERC), the integrated battery monitoring system can reduce battery maintenance and testing that technicians have to perform, lowering labor and maintenance costs. In addition, Green Cube’s GCC controller with PowCom™ software provides immediate access to performance and alarm information. This provides the operator with a single point where they can access and control their DC power plant remotely from anywhere and monitor the rectification and energy storage performance.

Battcon was a great validation of our high-efficiency DC power systems with lithium batteries that provide the highest efficiency level with a wide operating temperature and input voltage range for mission-critical applications.

Modern Material Handling: Lift Truck Tips, Transitioning to Lithium for Cold Storage

Posted on November 12, 2021 by Press Officer

All those frozen foods, subscription meal kits, and refrigerated foods and beverages that U.S. consumers increasingly buy, along with pharmaceuticals that need to be kept cold, equate to a need for more cold storage warehousing. Analyst firm Grandview Research pegs the cold storage warehousing sector to expand at a compound annual growth rate of 13.5% from 2021 through 2028.

Some cold storage DCs may opt for automated storage and retrieval systems or other automation to minimize the need for lift trucks. But for many cold storage DCs, electric lift trucks are relied upon to handle goods.

Cold storage is a challenging environment because of the way the cold negatively impacts the normal capacity of a conventional lead acid battery and issues related to condensation when trucks move between cold storage and ambient parts of the facility for battery swaps and charging.

Airport Industry Review: Li-Ion Batteries Offer Safe, Efficient, Green Power for eGSEs

Posted on November 12, 2021 by Press Officer

Jerry Crump, director of GSE business development at Green Cubes Technology, highlights the benefits of lithium-ion batteries for ground support equipment in airports.

Though electric ground support equipment (eGSE) is not a new technology on our airport ramps, it is constantly evolving and is not without challenges – particularly when it comes to implementing the energy needed for eGSE to effectively support airport operations.

Airlines, ground handling companies, and fixed-base operators can utilise new lithium-ion technologies, such as lithium iron phosphate, maximising the available power from their charging infrastructure to keep up with airline and airfield operations and the high power demand curve of certain eGSE’s – like cargo loaders and pushbacks.

Lead Acid – The Neurotoxic Rube Goldberg Machine of Energy Storage

Posted on October 30, 2021 by Press Officer

For both our employees and community, I want to address the health, safety, and environmental problems with Lead Acid. The single-biggest environmental issue with Lead-acid batteries involves the Lead component of the battery. Lead is a heavy metal with dangerous health impacts. Ingestion of Lead is especially dangerous for young children because their brains are still developing and Lead is a neurotoxin. Historically, sources included Leaded gasoline, Lead-based paints, and tin/Lead solder used in electronics manufacturing, pipes, and building construction, but those have largely been eliminated over the years. According to the World Health Organization (WHO), today around 85% of the world’s Lead consumption is for the production of Lead Acid batteries.

To mitigate the risk of the toxic impact, the often-cited claim is that Lead-acid batteries are 99% recyclable. However, Lead exposure that takes place during the mining and processing of the Lead, as well as during the recycling steps is the very source of environmental contamination and human exposure. There are many places where the process is poorly controlled often carried out without the necessary processes and technologies to control Lead emissions.

The California Department of Toxic Substances Control (DTSC) has written extensively on the case of Exide Technologies, a Lead-acid battery manufacturing company. Exide had to close down a large battery recycling plant in California after it failed to meet emission controls and waste management standards. California regulators believe as many as 10,000 homes could be contaminated with Lead from the plant. The cleanup will take many years and cost hundreds of millions of dollars. As a business, Exide has gone through multiple bankruptcies due the environmental impact cost of Lead. Battery recycling plants in other states have also been cited for contaminating the environment with Lead.

The WHO has reported cases where contamination from Lead-acid battery recycling resulted in a number of negative health effects — including the harm to children. Thus, while the 99% recycling claim sounds impressive, it understates the problem of Lead contamination via the recycling process. The situation would be much worse if these batteries are not recycled, as a single Lead acid battery in a landfill has the potential to contaminate a large area and cause harm to thousands of people. The health, safety, and environmental risk of Lead recycling far outweighs the benefit, particularly now that Lithium offers a clean, safe, and cost-effective alternative. From a productivity point of view, distribution centers that use electric lift trucks go through so many complicated steps to make Lead Acid work, including:

Battery change rooms
Extra batteries needed to support high volume operations
Safety equipment for acid spills (spill kits, eye wash, protective clothing and PPE)
Blood testing of employees for Lead poisoning
Watering
Equalizing
Fumes
Long charge times, waiting, and down time
Maintenance on the added equipment and process steps
Inaccurate fuel gauges and unknown cycle life due to deep discharge effects

With our customers, this means providing clean reliable energy storage and motive power for industrial applications. The complexity of the process to make Lead Acid batteries work would make any Rube Goldberg Machine maker proud. This “machine” concept is named after the American cartoonist Rube Goldberg, whose cartoons 100 years ago often depicted devices that performed simple tasks in indirect convoluted ways. It’s well past time for Lead Acid to have a place in the real world of industrial energy storage and motive power applications. It’s time to get the Lead out of batteries and the contamination of our environment from the Lead recycling process. It’s time to move to Lithium SafeFlex and the opportunity to realize the benefits of clean, reliable, innovation.
