Q&A with SWTCH Head of Strategy Sofia Berrada Cars and their drivers come in all shapes and sizes, colors and creeds, and when it comes to keeping them charged, there’s no one-size-fits-all solution. Different EV infrastructure applications require different combinations of hardware, software and services, and as the charging market develops, different companies are emerging… Read more »

PHYTEC to showcase modular charge controllers at Power2Drive Europe
PHYTEC Messtechnik produces modular embedded electronics designed to accelerate and simplify the development of EV charging solutions. At the upcoming Power2Drive Europe trade show in Europe, the company will present two new products: the phyVERSO-EVCS charge controller, which features an open-source-based operating system; and the EVCS-Cube—a complete development kit for prototyping and functional testing of… Read more »
Hyperdrives selects CISSOID’s inverter control modules for electric motors
Electric motor technology developer Hyperdrives has chosen CISSOID’s silicon carbide (SiC) Inverter Control Modules (ICMs) to power its hollow conductor-cooled electric motors. Hyperdrives’ approach uses a direct cooling system that dissipates heat at its source by channeling cooling fluid through hollow conductor windings. This design enhances heat dissipation by a factor of 10, the company… Read more »
Terawatt opens its first medium- and heavy-duty EV charging site in California
Terawatt Infrastructure’s medium- and heavy-duty EV charging hub in Rancho Dominguez, California is now fully operational. Located 12 miles north of the ports of Long Beach and Los Angeles, the Rancho Dominguez site is strategically positioned to support electric trucking fleet operations in and out of the largest container ports in the US. Initial customers… Read more »
Finnish Minerals and Beijing Easpring begin construction of a cathode material plant in Finland
Finnish Minerals and Chinese battery materials producer Beijing Easpring Material Technology have started construction of a plant in Kotka, Finland to produce cathode active material (CAM) for lithium-ion batteries. The plant’s first-stage capacity will be 60,000 tons of CAM per year. The plan targets commercial production in 2027 and includes the possibility of expanding production… Read more »
SK On and SK Enmove showcase battery immersion cooling
South Korean battery and trading company SK On is showcasing advanced thermal management technology with lubricant supplier SK Enmove. The immersion cooling technology for EV batteries circulates electrically insulating thermal fluids inside the battery pack to effectively dissipate heat. Since the coolant directly contacts the battery cells, it can more effectively suppress temperature rise compared… Read more »
How FLO’s vertical integration boosts EV charging reliability: build, own, operate, maintain
Q&A with Yann Benoit, FLO’s Senior Director for Network Operations. Reliability problems plague the EV charging industry. The state of public charging is so bad that many now consider it one of the biggest impediments to large-scale EV adoption. Physical damage to the charging stations is seldom the problem, so why do these darn things… Read more »
A closer look at purpose-built power analyzers for precise EV test and measurement
Q&A with EV measurement engineering experts Coty Harrison and Cristian Loris of Yokogawa Test&Measurement. When tasked with measuring the electrical power of complex systems like EVs, an inexperienced engineer may first reach for general instrumentation like oscilloscopes, data acquisition (DAQ) systems and digital multimeters (DMMs). While these instruments serve useful roles in electrical testing—oscilloscopes analyze… Read more »
Amprius ships new 6.3 Ah silicon anode cell to light electric vehicle company
Amprius Technologies, a manufacturer of lithium-ion batteries that use silicon anode technology, has shipped its new 6.3 Ah SiCore cell to an unnamed customer that is in the light electric vehicle segment, a member of the Fortune 500 list. The battery is intended for applications that require more efficient energy storage solutions, the company said,… Read more »
A closer look at multilevel traction inverters
The vast majority of EV traction motors must be supplied with sinusoidal 3-phase alternating current with the frequency proportional to RPM, and the overwhelmingly favorite way to do this is with a triple half-bridge voltage source inverter, or VSI. In this topology, each bridge switch can connect its output terminal (i.e. motor phase winding) either… Read more »
