Weighing Current-Sensing Options in EV Applications
Sept. 29, 2023
Due to the myriad technology alternatives out there, selecting the best EV current-sensing method becomes a challenge.
https://www.electronicdesign.com/technologies/power/article/21274622/electronic-design-weighing-currentsensing-options-in-ev-applications?utm_source=EG+ED+Analog+%26+Power+Source&utm_medium=email&utm_campaign=CPS230922070&o_eid=7211D2691390C9R&rdx.identpull=omeda|7211D2691390C9R&oly_enc_id=7211D2691390C9R
Fundamental Sensor Types
Four sensor types comprise a “short list” of choices in EV applications, though other options can also be relevant. They are the shunt resistor, Hall-effect sensor, fluxgate sensor, and current-sensing transformer. Each of the four has strengths and weaknesses, and some overlap in terms of the best choices for a given challenge. The strengths and weaknesses described here are broad generalities.
The shunt resistor works for both AC and DC currents.
The problem with using a shunt resistor is that it is a resistor, with a power penalty proportional to the square of the current passing through.
And, of course, it does produce a voltage drop. As might be expected, that resistance can result in heating
Hall-effect current sensors work well for AC and DC and high or low currents, but performance is limited with higher frequencies. By nature, they’re smaller and well isolated, let alone accurate within certain current ranges.
Hall-effect devices have a susceptibility to external or residual magnetic fields that can impact measurement accuracy.
Fluxgate current sensors can generally work with both AC and DC, offering good isolation, good low-current performance, slightly greater size and complexity, and often better accuracy than Hall-effect devices. Fluxgate sensors, built around nonlinear magnetic materials, depend on changes in magnetization related to the magnetic field created by the current. This produces precise as well as highly linear results.
Current transformers convert a high primary current into a smaller secondary current, which makes them useful particularly when it comes to AC current measurement. Current transformers can measure high current while consuming very little power.
Most battery packs deliver a voltage range of 300 to 450 V DC, and that current is delivered to one or more electric motors.

RS-485: High-Fault Protection, Wide-Input Common Mode,
and Deglitch Function
https://www.ti.com/lit/an/slla585/slla585.pdf?HQS=asc-int-catan-anahub_slla585-agg-mc-electronicdesign_ana-wwe_int&DCM=yes&dclid=CMbS7-e3rYEDFUKgAAAdrtQDkA#new_tab
THVD2410 and THVD2450 are ±70-V fault-protected, halfduplex, RS-422/RS-485 transceivers operating on a single 3-V to 5.5-V supply. By leveraging these useful
features, the RS-485 system design become much easier and the system is more robust
2.1 High Voltage Fault Protection
In some applications, the RS-485 bus might be exposed to high voltage, due to various reasons like direct shorts
to power supplies, mis-wiring faults, connector failures, damaged cables, and tool mis-applications. The ±70-V
fault-protection of THVD24x0 means that bus interface pins are protected against up to ±70-V DC overvoltage
conditions mentioned above. For example, the A and B pins are accidentally shorted to 48-V power supply
in an industrial automation equipment. THVD24x0 devices will not be damaged in this fault condition. As the
communication fails, the fault condition can be detected and cleared. After the 48-V DC short is resolved, the
devices resume working normally without requiring a power cycle.

Universal automation lays the foundation for smart factories
Universal automation can help make smart factories a reality in process industries and giving users more freedom and flexibility in their day-to-day activities.
https://www.controleng.com/articles/universal-automation-lays-the-foundation-for-smart-factories/?utm_source=IIoT+Sensing%2C+Connectivity+%26+Analytics&utm_medium=Newsletter&utm_campaign=CFECD230926004&oly_enc_id=0462E3054934E2U
Learning Objectives
Understand the shift toward the smart factory and the challenges process manufacturers face.
Learn how IEC 61499 and IEC 61131-3 are impacting universal automation.
Learn about universal automation’s benefits and how technology such as Ethernet-APL and edge devices will improve users’ intelligence.
Smart factory and automation insights
Distributed control system (DCS) users are working toward eliminating the proprietary nature of automation and working toward a universal standard for process control industries.
The future smart factory
Companies and users need to ask if they have a vision of what the smart factory will look like in five to 10 years. How will devices be connected? Will companies be dealing with vendors that work in a proprietary world, or vendors that manufacture hardware that work in an open world?
The vision is hard to see because technology and factory floor investments evolve so slowly. Users see the small picture when they install devices on the factory floor today as most have an option to connect via Ethernet. All of these devices are becoming smarter and are capable of providing a tremendous amount of data analytics.
It’s not hard to imagine a time in the near future where all devices and instruments on the factory floor are connected via Ethernet. If all these devices are connected, and they are all smart, why can’t they talk to each other? That connectivity is coming and is referred to as control at the edge.
In the PLC world, programmers have used the IEC 61131 languages for more than 20 years. Some manufacturers have adopted it more than others, but none provided ability to program another vendor’s PLC with their software. None of the code being developed is portable to another manufacturer’s system, creating the very proprietary nature of the PLC world today. But why should it be this way? Proprietary technology hinders innovation, slows technology advancement and limits a customer’s options.
There is another standard developed in 2005 called IEC 61499. This function block-driven standard is now starting to gain traction because the timing is right to use it now. IEC 61499 extends IEC 61131-3 by improving the encapsulation of software components for increased reusability, providing a vendor independent format and simplifying support for controller-to-controller communication. Its distribution functionality and support for dynamic reconfiguration provide the required infrastructure for Industry 4.0 and Industrial Internet of Things (IIoT) applications.
However, there are additional developments marking this transition to smart factories.
Universal Automation is pushing towards a factory floor standard
There are a group of end users and Manufacturers getting on board with IEC61499 and Universal Automation, which is an independent, not-for-profit association of users and vendors managing the implementation of a shared source runtime execution engine based on the IEC 61499 standard. This level of shared technology provides the basis for an ecosystem of portable, interoperable, “plug and produce” solutions and creates a new category within industrial automation.
Why is this important? This is a huge step to disconnecting the hardware from the software. By adopting universal automation, any vendors control software utilizing IEC 61499 will be able to run on any universal automation hardware. This allows the end user to choose best-in-class products on the factory floor to match the application.
Ethernet-APL to help field instrumentation communication
Ethernet with an advanced physical layer (Ethernet-APL) enables long cable lengths, explosion protection via intrinsic safety and power over Ethernet (two wires).
Based on IEEE and IEC standards, Ethernet-APL supports any Ethernet-based automation protocol and will develop into a single, long-term stable technology for the process automation community. This Ethernet standard is made specifically for the manufacturing and process industries to speed the adoption of extending Ethernet communications down to the field instrumentation.
Next generation automation platform can be interoperable
Next generation automation platforms have software is built on and around Universal Automation concepts and IEC 61499 to address the new connected factory floor. Controllers provide a distributed architecture to the edge. Control algorithms from the software can be deployed to various controllers and compliant Universal Automation partner IO devices proving the best-in-class concepts, such as a controller than runs inside a variable frequency drive (VFD), medium- and high-performance controllers with scalable I/O, and virtual PLC and edge computing.
