Lithium Battery DC Fast Charging Interface Standards
I have spent more than a decade building lithium battery packs for vehicles and industrial equipment, and most DC fast charging debates obsess over kilowat…
Home Energy Storage for Rural Fire and Water Districts
I have spent a good part of my field time on the far end of rural feeders: volunteer fire halls at the end of a two-mile spur line, pump houses sitting alo…
Battery Solution for Rail Yard Shunting Equipment
Rail yards are the least glamorous and most abusive environment in the rail industry. Shunting engines start, accelerate, brake, and idle hundreds of times…
Lithium Battery for Scissor Lifts and Aerial Work Platforms
I have spent more of my career than I expected standing next to an aerial work platform that would not start on a Monday morning. The machine was usually f…
Home Energy Storage Thermal Envelope for Cold Basements
I have lost count of how many home energy storage systems I have walked into that were installed in exactly the same place: an unfinished basement, on a po…
Battery Solution for Theme Parks and Attractions
Most discussions about power at a theme park start with the rides and end with the generator. The projects I get called into start elsewhere: the utility f…
Lithium Battery Cycling at Partial State of Charge
Most buyers read a lithium battery datasheet, find a cycle-life number, and build a duty plan around it. That number was measured at one depth of discharge…
Home Energy Storage Interconnection Agreements and Queues
Most home energy storage projects I review do not fail on cell chemistry, weld quality, or inverter sizing. They fail on paperwork. I have signed off on se…
Sodium-Ion Battery for Construction Site Temporary Power
Diesel generators still dominate temporary site power: cheap to rent, familiar, and nobody was ever fired for ordering one. But after twelve years building…
Battery Solution for Water Treatment Pumping Stations
Pumping stations are the least photographed asset in a water utility and the one that punishes a power outage fastest. A treatment plant can coast for twen…
