One question that I have concerning shunts. We have various values of bar shunts here at our lab that we use for measuring current levels from 10a to 5000a. Is it necessary to actually prove the resistive value at various temperature due to self-heating, or is it acceptable to use thermal coefficients from the manufacturer? Also, in dealing with the high current, it is also important on the physical connections and orientation of the connections. Do you have any good sources of information on this topic?

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
