For most of the history of lithium battery packs, the module was taken for granted. Cells went into modules, modules went into packs, and the only questions were how many
An electric vehicle is not an internal combustion vehicle with the engine replaced. The powertrain has an order of magnitude fewer moving parts and considerably more electronics,...
Renewable energy has spent two decades winning an argument about cost. It largely won. What it inherited in return is a manufacturing problem, because the price ....
Wind turbine manufacturing is an unusual industry. It produces some of the largest moving structures ever built in series, to tolerances borrowed from machine tools..
A wind turbine blade is a composite structure designed to survive twenty years of load reversal in open weather, built in a mould large enough to park a train in,
Renewable energy has spent two decades winning an argument about cost. It largely won. What it inherited in return is a manufacturing problem, because the price ....
Quality control in most manufacturing answers one question: does this part meet specification today. Battery quality control has to answer a harder one: will this pack...
The full battery manufacturing process: electrode coating, calendering, cell assembly, formation and pack build, plus where yield is lost at each stage.....
Almost every wind turbine generating power into a grid today is an axial flow machine. Wind travels along the axis of rotation, passes through a rotor mounted perpendicular ....
Vertical axis wind turbines have spent most of the last century as the road not taken. Georges Darrieus patented the lift driven vertical rotor in 1931. Sandia National Laboratories....
