Sure, but as an engineer designing high-volume products it is critical to reduce costs wherever possible. Writing the resistance on every fuse if not needed by the car is an area where costs can (and will) be removed. The LEAF is certainly at volumes where all suppliers are looking to remove any unnecessary costs, but I guess as a compliance car the RAV EV is not at that point, yet.Ingineer said:As an Engineer working on implementing circuit protection, one must ensure that the fuse being added doesn't have adverse effects on the circuit. Semiconductor fuses are used because they add relatively little resistance to things like IGBT/MOSFET switching circuits which demand low impedance current paths in order to remain operating within the design parameters.
Yeah, I originally thought the two-terminal connector shown was for the Kelvin leads. Does anyone know what they connect to? Perhaps that is just an interlock mechanism to ensure the cover is installed?Ingineer said:There's nothing preventing you from using any fixed resistance as a current shunt, but without kelvin-type connections, (which this pictured setup lacks) it's not going to be reliable enough to get a good reading.
