On a battery pack assembly line, plasma cleaning sits between cell feeding and welding, occupies very little space, adds seconds to the cycle and is frequently the station ...
End-of-line testing is the last opportunity to stop a defective battery pack leaving the plant, and it is routinely asked to do more than it can. A pack that passes
A battery pack is a group of cells asked to behave as one. They never quite do. Cells leaving the same production line differ measurably in capacity, in internal resistance
Three measurements dominate cell testing in battery production, and they are routinely treated as three ways of checking the same thing. They are not. Each answers a different...
Every cell in a battery pack has to be joined electrically to its neighbors, and in a pack containing several hundred cylindrical cells that means thousands of individual connections...
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,
