Electric Vehicle Charging Solution

AeroVironment Inc. and eMotorWerks have integrated their platforms to create increased charging capabilities for customers and electric demand load aggregation for utilities.

AeroVironment charging solutions with eMotorWerks’ JuiceNet will enable EV drivers to gain benefits that include smartphone, web and Amazon Alexa voice control over charging; real time and historic energy usage for cars; notifications of charging status; load balancing two or more EVSEs on the same electrical circuit to share the load while avoiding tripping breakers; and setting charging schedules that correspond to lower utility rates, saving customers money on charging.

For electric utilities, the JuiceNet integration, via open APIs and industry standards such as OpenADR, makes it possible to aggregate fleets of charging EVs. Such a high level of control over EV charging load allows utilities to modulate energy demand on the grid, and to shift and spread out EV charging loads to times when renewable resources are more abundant or energy rates are lower.

Next-Generation Prepay Meter

Landis+Gyr Prepay is designed to help utilities manage resources using edge intelligence to support a more balanced, efficient and flexible distribution network. Edge computing capabilities built into the prepay solution automate communication and decision making at the premise and provide a future-proof technology to solve resource management challenges across the grid.

Landis+Gyr Prepay integrates with a utility’s existing CIS and payment infrastructure. Energy usage and account balances are tracked in the meter, with real-time account and usage information delivered to the consumer via a robust in-home digital display unit, as well as a consumer engagement platform. The solution is supported on the FOCUS AX-SD Meter and within Command Center 7.1.



Fault Transmitter and Receiver System

Schweitzer Engineering Laboratories Inc. (SEL) is introducing a fault transmitter and fault receiver system that sends fault signals to relays and recloser controls within six milliseconds.

The SEL-FT50 Fault Transmitter and SEL-FR12 Receiver System provides a new, unique approach to distribution system protection. Individual branch status inputs enable users to eliminate unnecessary coordination delays to quickly and securely clear faults while minimizing the number of affected customers and reducing equipment damage.

SEL-FT50 Fault Transmitters can be installed on laterals, branches and the main line to broadcast fault statuses via an 860 or 900 MHz radio (depending on the region) to one or more SEL-FR12 Fault Receivers. The system, which includes up to 12 line-powered SEL FT50 Fault Transmitters and 1 SEL-FR12 Fault Receiver, communicates fault data wirelessly up to two miles using MIRRORED BITS communications.

Power Module Step-Down Regulator

Analog Devices Inc., which recently acquired Linear Technology Corp., announces the LTM8073, a uModule (power module) step-down regulator with up to 60V input voltage range (65V abs max). The device can safely operate from unregulated or fluctuating 24V to 48V input supplies in noisy environments such as communication infrastructure, factory automation, industrial robotics and avionics systems. The Silent Switcher architecture minimizes EMC/EMI emissions, enabling the LTM8073 to pass CISPR 22 Class B for use in signal processing applications, including imaging and RF systems.

The output voltage is adjustable with one resistor from 0.8V to 15V. This wide output voltage range provides the versatility of using one product to generation common system bus voltages of 3.3V, 5V, 12V and 15V. The efficiency at 24VIN to 5VOUT at 3A is 90 percent.
