LITHIUM SAFEFLEX BATTERIES AND CHARGERS

Maintenance free Li-ion batteries increase safety and efficiency with a lower total cost than lead acid.

High-frequency chargers with CAN communication, voltage detection and multiple outputs enable fast charging with lower utility costs.

“LFP has a couple of advantages; its life cycle is inherently much longer than NMC. It is safer in the sense that if you have did have a rare thermal event with LFP the worst the peak temperature is much lower,” Schneider said. The disadvantage of LFP is energy density, according to Schneider. “It takes up more space than NMC, but that is not a big issue in an industrial truck,” she said.

In addition to batteries, Green Cubes has developed chargers, which Schneider said includes “the highest efficiency and smallest charger” in the market. She said a lot of customers are interested in a seamless system of batteries and chargers.

In the near future, the company is monitoring the work of the California Air Resources Board, an organization that oversees the state’s efforts for air pollution control, including proposals of electrification of internal combustion engines, according to Schneider.

The state legislature is currently in the comment period of legislation that may phase out Class 4 and Class 5 lift trucks between 2026 and 2035, according to Schneider. “It’s yet to be seen exactly how that is going to phase out,” she said.

Exploring power options

Some in the industry are seeing interest in diverse power solutions. At EnerSys there are three battery technologies available to address all needs and budgets, according to the company website.

The business has developed modeling software that “eliminates guesswork and can use application data for actionable intelligence to identify the ideal battery and charger combination based on a customer’s specific operations and goals,” the site said.

EnerSys offers Ironclad® traditional flooded lead acid batteries as well as “virtually maintenancefree NexSys® PURE Thin Plate Pure Lead (TPPL) and NexSys® iON Lithium-ion (Li-ion) batteries, according to the business website. In addition, the company offers a range of charger technologies including a new wireless option for AGVs, the site said.

Harold Vanasse, Senior Director of Marketing, Motive Power Global, for the company, said like any newer technology, there is an adoption curve for lithium ion. “Flooded lead acid has been around for a long time,” he said, noting that for many EnerSys customers, lead acid technology is still preferred. But interest in maintenance free technology is strong and varies, so he said the consultations EnerSys can provide are key. Vanasse said the company’s experts help size up what technology will work for a client, what the budget considerations are and more.

Chris Behan, Senior Marketing Manager, Motive Power Americas, for EnerSys, said the company will gather equipment energy usage data as well as shift and break patterns for charging to paint a complete picture.

All of that information is input into the EnerSys simulation software, to help customers make fully informed decisions of power needs, according to Behan. The company’s offering of a one-stop shop for battery and charger needs is also valued by its customers, according to Vanasse.

“We design and make our own chargers as well. It’s very much a closed-loop system. Everything is designed to work optimally together,” he said.

Industry trends

Vanasse said the shortage of labor, cost of labor and automation remain top considerations for EnerSys partners. Behan said an interesting trend has also been the number of customers wanting to move away from the costs and time associated with battery maintenance.

For some, thin plate pure lead is a good option if they don’t require the full power of the Li-ion option, Behan said. “We try to right-size the power system for the application,” he said, noting some operations, like a 24-7 facility, can benefit from the advantages of lithium ion batteries that are designed to recharge fast during break periods.

“Another trend you see is automation,” said Vanasse, who said maintenance free TPPL and lithium-ion batteries often match up well with such efforts as businesses seek options to fill labor needs.

Sustainability is another top-of-mind subject for EnerSys partners, according to Vanasse.

Behan agreed, noting that for those looking for water savings, considering different battery options may help hit those goals. “Our NexSys solutions never have to be watered,” he said.

Vanasse said he envisions the lithium-ion technology will continue to evolve over the coming years, with the cells becoming more energy dense. “We’re going to see an evolution in those chemistries,” he said.

EnerSys recently debuted its wireless charging options, which both Vanasse and Behan said are of interest to companies looking to drive up efficiencies with automated equipment.

In the near future, the EnerSys sales team are looking forward to continuing to apply customer data to hone down what is best for each operation. And Vanasse said the company will likely release the next generation of that software in a year or so. “We’re still continue to evolve thin plate pure lead and lithium-ion products,” he said, encouraging material handling companies to look through their various power options and use data to help make the best choice.

“Have that conversation with us,” he said. “There is no one-size-fits all solution and we don’t want customers to guess at what they need. The costs of a bad decision are very high.”

Blocks the Spread of FireActivates the Sprinkler System

Today’s warehouse fire protection systems include more than just pipes and sprinklers. When the products being stored include highly flammable items such as plastics, aerosols, liquors or oils, fire barriers may be required inside the racking structure.

Solid steel rack decking and flat sheet accessories from DACS make effective fire or heat barriers in warehouse environments.

They can be used on storage racks horizontally or vertically to block the spread of fire, or to capture heat for in-rack sprinkler activation.
