Total control of power usage: from solar to EV and back to the house. Bidirectional charging promises to completely transform the vehicle ownership experience. Once an EV can double as a stationary storage device, it will take its place as part of an energy ecosystem that includes rooftop solar and energy management—and could even become… Read more »

Littelfuse’s new high-current, high-voltage cartridge fuse is designed for EV charging
Circuit protection specialist Littelfuse has unveiled a new high-current, high-voltage, compact cartridge fuse designed for overcurrent protection in EV charging equipment. The 607 Series is rated at 500 V, from 40 to 63 A, and has a 10,000 A interrupting rating. Littelfuse is offering the through-hole fuses in tray packages of 500. The fuses work… Read more »
2022 Ford F-150 Lightning First Drive: Ford’s most valued model is now electric
Ford knows trucks, and demand for its F-150 Lightning shows truck buyers may not be as afraid of EVs as many think. The 2022 Ford F-150 Lightning pickup truck may be the first real mass-market electric vehicle sold in the US. Used by individual owners and businesses alike, pickups are a massive part of the… Read more »
Henkel introduces new protective coatings for battery housings
German chemical company Henkel has introduced two new coatings designed to protect battery housings from heat and fire in case of a thermal runaway event. The company says, “When applied to battery packs, the coatings help to inhibit and delay the spread of fires to protect the passengers as they evacuate the vehicle.” Loctite EA… Read more »
The high cost of cobalt cathodes and some potential alternatives
According to an article published in Advanced Energy Materials by researchers at the DOE’s Oak Ridge National Laboratory (ORNL), cobalt is currently the most expensive cathode material used in lithium-ion batteries. The DOE says cobalt accounts for about a quarter of the cost of a typical battery, and was the most expensive cathode material in… Read more »
Indium to launch new adhesive for power module assembly
Indium Corporation, a designer and manufacturer of materials for electronics assembly, plans to release a new adhesive for power module assembly at PCIM Europe, which is scheduled for May 10 to 12 in Nuremberg, Germany. InTACK is a halogen-free adhesive designed to hold a die, chip or solder preform in place during the placement process… Read more »
Researchers develop method for stabilizing interfaces in solid-state batteries
Researchers at MIT and the DOE’s Brookhaven National Laboratory have developed a method for stabilizing the interfaces between the electrolyte and cathodes in solid-state batteries during the sintering process. Based on research reported in Advanced Energy Materials, the team found that when temperatures are above a few hundred degrees Celsius, carbon dioxide and reactions unfold… Read more »
Why is Tesla no longer including mobile charging cables with its vehicles?
First-time EV buyers are famously nervous about charging, which is one reason that most new EVs come with a portable charging cable—it’s reassuring to know that you can plug your new car in as soon as you take it home, without having to deal with charger installation right away. Some drivers find the portable adequate… Read more »
How to test the functionality and safety of EV charging stations, easily and reliably
Sponsored by Fluke Easy EVSE safety testing and troubleshooting with the Fluke FEV100 Test the safety and performance of type 1, level 1 or level 2 electric vehicle ac charging stations (EVSEs) with the Fluke FEV100. This test adapter simulates the presence of an electric vehicle, allowing you to conduct tests in combination with appropriate… Read more »
Are solid-state batteries always safer than Li-ion?
Many in the EV industry see solid-state batteries as the future, and one of the reasons is that the more stable solid electrolyte is expected to be safer than current liquid electrolytes. However, new research indicates that the picture may be more complex. A recent study led by the DOE’s Sandia National Laboratories, published in… Read more »
