Yokogawa Test & Measurement Corporation has released its PBDH0400 series differential probe with a maximum input voltage of 2000 V and a frequency bandwidth of 400 MHz.
The probes can deliver the measurements required for developing the next generation of higher speed power devices. Read more…

LEM has developed a current sensor for transformerless, bi-directional, onboard chargers (OBCs), writes Nick Flaherty.
The automotive-grade, residual current monitoring (RCM) sensor is the first of its kind for bi-directional OBCs with ASIL B safety rating. Read more…

Electric vehicle (EV) lithium battery fires in facilities such as factories, warehouses, parking structures and ships, though rare, are lethal and destructive when they happen, but remote monitoring of battery temperature can provide a timely warning of a developing problem, writes Peter Donaldson. Read more…

Researchers in Korea have developed a cost-effective and eco-friendly technology for recycling cathode materials from spent lithium-ion batteries through a simple process within an existing cell without the need for disassembly, writes Nick Flaherty. Read more…

With the market launch of its ZF Bike Eco System, ZF has given details of its three-step service and training concept, which, it says, guarantees minimal effort for manufacturers, dealers and customers when it comes to servicing and retrofitting. Read more…

Researchers in the US have developed a solid-state filter for power converters that does not need a capacitor.
Capacitors are one of the main points of failure in an e-mobility power system, responsible for 30% of failures in power electronics. Read more…

Primarily known as a producer of chemical solutions across a number of different industries, German multinational group Henkel has launched a Battery Engineering Center (BEC) within its Inspiration Center Duesseldorf, aimed at providing strategic partnerships to OEMs and battery manufacturers (and others in the e-mobility space) through the BEC and its services and products there. […] Read more…

University of Waterloo researchers have made a key breakthrough in developing next-generation batteries made of magnesium instead of lithium.
When the idea to create batteries using magnesium was first shared in a seminal academic paper in 2000, the novel design didn’t provide enough voltage to compete with lithium-ion batteries. Read more…

Hyundai Mobis (KRX 012330) announced on 18th that it has developed a new battery cell cooling material to prevent battery overheating during ultra-fast charging of electric vehicles. Read more…

NXP Semiconductor has developed the first battery management system (BMS) using ultra-wideband (UWB) technology, writes Nick Flaherty.
Using wireless connections between battery cells and the BMS in a pack simplifies assembly and enables better energy density. Read more…

Vicor has developed three automotive-grade power modules that can be used in 300 combinations in 48 V EV systems, writes Nick Flaherty.
They cover a bus converter from 800 V to 48 V, an unregulated 48 V to 12 V converter and a regulated 48 V power-supply module. Read more…

Wright Electric has finished assembling its second-generation megawatt-class motor, the WM2500, writes Nick Flaherty.
The motor has been built with support from the US ARPA-E ASCEND research programme and NASA, and it is spinning freely after being assembled in December. Read more…
