Battery Management
Options for current sensing, Part 2
Part 1 of this FAQ discussed the issue of current measurement, and four transducers which can be used to measure current. The first two – shunt resistors and Hall-effect devices – can be used for AC or DC currents. We will now look at two other transducers – the Rogowski coil and the current transformer […]
Options for current sensing, Part 1
The need to sense and measure current at one or more points is a circuit is very common. In situations ranging from microamps going into or out of a battery, to DC current from a solar panel, to feedback for a power supply controller, to tens or hundreds of amps of AC power to a […]
Managing EV batteries squeezed into odd shapes
Automakers are forced to fit EV batteries into nooks and crannies in an effort to maximize driving range. The resulting convoluted layouts call for a wireless approach to managing cells. GREG ZIMMER | Linear Technology Corp., now part of Analog Devices Inc. Lithium-Ion batteries require considerable care if they are expected to function reliably over […]
