DC-DC converters for EVs with IP67 option

Green Watt Power, a division of Powerland Technology, has launched its EVD3000 series of fully encapsulated, ruggedised DC-DC converters for EVs. They have an input range of 280 to 880 V, with output voltages of 27.5 or 48 V DC to power auxiliary EV functions such as air conditioning, lights, instruments, accessories, or to provide […]

High-speed marine motor addresses critical need

Rapid acceleration may not be the first thing that comes to mind when considering marine vehicles that serve the offshore industries, but it is important because it increases their operational limits, enabling them to be deployed for longer in higher sea states (writes Peter Donaldson). That is one of the key selling points of Walker […]

CSM launches split HV measurement modules for confined spaces

CSM has unveiled its latest measurement technology solution for electric and hybrid vehicles where installation space is limited. Called the HV Breakout Module (BM) Split system, it provides high-frequency measurement of current, voltage and power directly in HV power cables as well as busbars. The split design allow measurements at points where there is not […]

Making the cases for battery transport

As the EV industry grows, the logistics of moving major components – particularly batteries – between facilities has to be closely considered, argues Olivier Saada, business development manager for containers at battery transport packaging specialist Corplex (writes Peter Donaldson). EV batteries are considered dangerous goods and fragile items, and the company makes cases that are […]

Wireless charging by magnetic induction

Andy Daga, founder, president and CEO of Momentum Dynamics, wants to make charging EVs easier than refuelling IC-engine vehicles while enabling practically unlimited range in day-to-day driving, at least in urban and suburban environments (writes Peter Donaldson). The company is now rolling out its wireless charging system based on magnetic induction technology for large vehicles […]

Cool SiC inverters move

Researchers at the US National Renewable Energy Laboratory (NREL) have been working with heavy-duty equipment maker John Deere on a new thermal management system for SiC inverters (writes Nick Flaherty). Equipment such as trucks and construction machines account for 39% of greenhouse gas emissions in the transportation sector, so there has been a focus on […]

A case of plastic over aluminium

Containing thermal runaway, protecting EV occupants from fire and saving weight are all drivers for the application of new materials to batteries, and the battery case is a prime target for replacing aluminium alloy with plastics (writes Peter Donaldson). Multi-industry plastics specialist SABIC has recently re-engineered existing EV battery cases in two proof-of-concept exercises that […]

Dual-component power converter

Premo has developed an 11 kW power converter using its patented technology that integrates multiple magnetic components (writes Nick Flaherty). The 3DP-11KWHVHV combines a full-bridge 150 µH LLC resonant transformer and 25 µH resonant choke in a single unit. This cuts the volume of the converter by up to half, and can reduce the amount of […]

Koenigsegg announces its first e-motor and EV drive unit

Koenigsegg has unveiled its first e-motor, the Quark, which uses a torque/power-rich balance between radial (power-dense) and axial (torque-dense) flux topology it calls Raxial Flux. The company has also integrated two of them with one of its David inverters, plus planetary gearsets, to create a torque-vectoring EV drive unit it calls the Terrier. The company says a key […]

Inverter integration cuts size, weight

Texas Instruments has integrated a transformer into a gate driver to enable distributed switch architectures for inverters (writes Nick Flaherty). The UCC14240-Q1 isolated DC-DC bias supply module integrates the transformer and components with 3.5 mm-high planar magnetics to reduce the size, height and weight of a distributed power system in an inverter. The integration of […]
