This training series will discuss the design considerations for global EV charging station standards and the differences to consider for AC versus DC charging stations and for residential vs. public stations. The training also includes deep dives into the block diagrams with subsystem analysis and recommendations.
The Internet of Things (IoT) is now part of the smarter grid through the adoption of IPv6 communications networks. These 6LoWPAN-based networks address key concerns such as standards-based interoperability, reliability, low power, and long-distance connectivity.
Non-technical losses (“theft”) account for billions of dollars of revenue loss for utility providers around the world as individuals are able to hack meters to slow or stop the accumulation of energy usage statistics. This loss has driven increased requirements for enhancing the protection designed into new smart meters. This training session will discuss different methods of attacking smart meters and how TI’s analog portfolio can be used to detect or even prevent these attacks. In one scenario magnets are used to saturate any transformers present in the system.
We are all well aware that the demand for Electric Vehicles (EV) is increasing rapidly. This eight-part training session begins with a description of a typical EV system in part 1. Part 2 is a brief description of how both Lead Acid and Lithium Ion batteries are charged. Part 3 focuses on the types of power factor and harmonic currents. Part 4 discusses power factor correction and the typical boost PFC stage. Part 5 concentrates on the Phase Shifted Full Bridge topology, including the reasons why it is used and a detailed description of how it operates.

Hundreds of millions mechanical water meters are deployed around the world today. Market pressure pushes water utilities to add intelligence and allow for automated readout and billing on top of water waste control. RF-enabled electronic flow measurement modules provide a cost-effective solution without full meter replacement and are the main building block for fully electronic smart water meters with impeller principle.
Ultrasonic sensing techniques have been popular in smart water meters because the technology avoids any moving parts which are prone to degrade over the lifetime of the product. The MSP430FR6047 microcontroller (MCU) family takes ultrasonic sensing solutions to next level of performance delivering <25ps of accuracy, detection of low flow rates <1 liter/hour and high precision of <5ps.
PT100/500/1000 Resistance Temperature Detectors (RTDs) are widely used in grid infrastructure and factory automation applications where high precision temperature measurement is often required. Technical requirements include either 20 mK precise Differential Temperature Measurement (DTM) for heat and cold meters from 0 to 180°C or better than 400 mK precision over the full range of -200 to 850°C for industrial sensor transmitters.
Shunt sensors are rapidly replacing current transformers as the preferred current sensing solution for electricity meters(e-meters) around the world.
IPv6-based communications networks are becoming the standard choice in industrial markets such as smart meters and grid automation. These 6LoWPAN-based mesh networks address key concerns such as vendor interoperability, long-distance connectivity, security and reliability. This training will cover system- and software-level deep-dives on new RF 6LoWPAN mesh solutions, which implement open-source based 6LoWPAN mesh stacks on top of the frequency hopping based TI-15.4 stack.
Over the last few years, the industry has been moving from mechanical to fully electronic meters. We have seen more and more functionalities such as metrology with ultrasonic technology, leak detection with audio patterns, communication with low power and long range radio being added to smart meters. These new functionalities allow utilities to deliver new services such as condition-based maintenance and remote monitoring of meters, which lead to efficient management of the network and better customer experience.
