A closer look at high-power interconnects and disconnects

In the electrical/electronic world, the terms interconnect and disconnect both refer to a means of joining two sides of a circuit together. The subtle—and entirely informal—difference is that an interconnect is directly or manually operated (inserting a plug into a jack, for example) while a disconnect is indirectly or automatically operated, for example the moving… Read more »

NXP introduces new series of microcontrollers for EV control applications

NXP Semiconductors has introduced its S32K39 series of automotive microcontrollers (MCUs) for EV control applications. The company says these MCUs include networking, security and functional safety capabilities beyond those of traditional automotive MCUs.  The S32K39 MCUs are designed for the intelligent and high-precision control of traction inverters that convert the EV battery’s DC power to… Read more »

PG&E to offer vehicle-to-grid export rate for commercial EVs

Vehicle-to-grid (V2G) technology promises to be a true win-win: a powerful grid balancing resource for utilities and a source of incremental income for EV owners (electric school buses seem to be an ideal use case). But before V2G can really take off, there needs to be a system for utilities to compensate EV fleet operators… Read more »

2022 Lucid Air: The makers of the first 500-mile EV should be taken seriously

Created by engineers with years of EV experience, the 2022 Lucid Air is a stunning debut that confronts Tesla—and Mercedes-Benz—with a new competitor. It’s been a long time coming, but the 2022 Lucid Air has been worth the wait. The new carmaker’s all-electric luxury sedan not only competes directly with the aging Tesla Model S,… Read more »

The Pinellas Suncoast Transit Authority, which serves Charged’s home city of St Petersburg, Florida, hopes to add 60 electric buses to its fleet over the next five years. The PSTA board has unanimously approved an agreement with bus-maker Gillig to provide the 60 new e-buses. The procurement, which is expected to cost $80 million, including… Read more »

EV Analysis Solutions for Battery-Inverter-Motor Efficiency, Battery Structural Durability and Battery Reliability

Battery-Inverter-Motor EfficiencyThe theoretical and real-world range of an electric vehicle may differ significantly. To maximize the range and overall efficiency of the vehicle, it is necessary to understand and characterize how the vehicle is used and determine through measurement and analysis where efficiency losses occur. But quantifying AC power is particularly difficult for EV frequency-modulated,… Read more »

2021 Jeep Wrangler 4xe: The legendary SUV brand’s first plug-in hybrid

The plug-in hybrid version of the Jeep Wrangler offers useful all-electric range and great electric torque—if drivers plug it in. Do they? The accelerating pace of electric vehicle launches has brought us to this: The first Jeep in the US to get a plug-in hybrid version is the legendary Wrangler. In Europe, it was smaller… Read more »

Noodoe’s EV Exceed DC fast charger cranks out 950 volts

Most of today’s EVs operate on 400-volt systems, but 800 volts is clearly the near future. Higher-voltage systems can deliver the same amount of power with less current, which means that charging rates can get higher without making charging cables impractically heavy and bulky. Charger manufacturer Noodoe explains that DC fast chargers are going to… Read more »
