Pouch, prismatic or cylindrical cells in an EV pack: which conditions decide it
Judge cell form factor by the parallel count that pack voltage and capacity produce, and by the blast radius of one cell failure.
Renewable+ESS Ramp-Rate Control — The SOC Band Interlock That Comes Before the Schedule, and ΔP²/(2R)
Ramp-rate limiting needs headroom to charge and discharge at once. Size the SOC band from ΔP²/(2R) and keep the EMS schedule inside it with an interlock.
Radiation Monitor Ventilation Isolation Interlocks: Isolation Order Comes Before Voting Logic
Isolating controlled-area ventilation on a radiation signal: enforcing supply stop, filter train diversion and normal exhaust closure in order, plus channel voting and degraded logic.
Ammonia Cracking vs Liquid Hydrogen — The Import Path Is Decided Backwards from the Final Consumer
The hydrogen import path turns on the purity the final equipment needs and the stockpile period, not shipping distance. Hydrogen density, cracking heat and a 30-day stockpile for 1 MW, calculated.
Nuclear Capacity Factor: Outage Critical Path and Unplanned Trips Matter More Than Cycle Length
Time availability calculated from fuel cycle and outage days to compare cycle extension against shorter outages and fewer unplanned shutdowns.
Servo Drive Noise: Design the Common-Mode Return Path Before Adding Filters
Much servo noise is a common-mode return path problem. Fix PE, shield termination and routing before adding filters.
Rolls-Royce SMR and ABB Team Up — How Far Does Electrical and I&C Standardization Pay in a 470 MWe Factory-Built Plant?
The ABB–Rolls-Royce SMR MoU as a case in where to draw the standardization boundary: standardize non-safety systems, design grid and safety I&C per site.
“Beyond Semiconductors”: What the Government’s AI Manufacturing Strategy Means for the Power Infrastructure Industry
A look at what the government’s ‘Beyond Semiconductors’ AI manufacturing innovation strategy means for the power infrastructure industry.
Ultra-Fast Charging: The Bill Goes to the Incoming Supply Equipment
CATL’s third-generation Shenxing charges 10-80% in 3 minutes 44 seconds. The conditions under which contracted demand, transformers and instantaneous peaks, not the cell, become the bottleneck.
Renewable Energy Direct Subsidies vs Auctions: Which Wins Under What Conditions?
An electrical engineer’s comparison of where direct renewable subsidies and auctions each fit, drawn by the number of developers and grid hosting capacity.
