Eaton’s lithium ion cells comply with rigorous safety standards such as the federal Department of Transportation’s UN/DOT 38.3 certification as well. The UPS hardware that contains them also comes with an onboard management system that measures cell voltages and temperatures to ensure that battery packs aren’t headed for thermal runaway conditions.
Eaton shipped its first UPS products with lithium ion batteries late in 2017. Demand for those systems has been strong so far, according to Del Misenheimer, senior vice president and general manager of Eaton’s power quality division.
“It’s slower in some of the smaller units, because the takeoff there is a little bit slower, but I would say in the larger section of the market, particularly around data centers, it’s moving very fast,” said Misenheimer in a February interview with ChannelPro during the vendor's annual partner summit conference. “Our sales were up over 100-and-some percent in 2018 versus what they were in ’17.” They’re on pace to increase 200 to 300 percent further this year, he continued.
Lithium ion 5P models are available for ordering now. According to Lindley, they will begin shipping within roughly one week.
