Emulator hands power back to grid


Keysight Technologies has updated its regenerative DC emulator to support higher power up to 270 kW for powertrain testing (writes Nick Flaherty). The Scienlab SL1800A Series regenerative DC emulator enables engineers to emulate the large batteries in EVs. The bidirectional power flow allows emulation of power sourcing applications such as traction inverter tests, as well as […] More…

In conversation: Matt Faulks


Hypercars to HGVs Viritech’s CTO tells Rory Jackson how fuel cell developments for its Apricale hypercar will feed into its upcoming heavy goods vehicles Anyone who works in electrified and low-carbon automotive engineering should remember that developing solutions to the zero-emissions challenge is not a zero-sum game. Just as solar, wind, tidal and nuclear power […] More…

Far-UK shows carbon fibre skateboard EV chassis


UK composite construction specialist Far-UK is developing a primarily carbon fibre skateboard chassis concept that can be applied to light vehicles with different configurations of wheelbase, track and either three or four wheels (writes Peter Donaldson). The platform is designed to help reduce barriers to entry for new vehicles by optimising the cost and time […] More…

Eco-friendly advance for lithium-ion cell production


Energy storage solutions provider Leclanché says it has achieved a breakthrough in the environmentally friendly production of G/NMCA cells, by reducing the cobalt content in NMCA cathode material from 20% to 5% and manufacturing the electrodes using a water-based process. In doing so, Leclanché says it completely dispenses with the use of the highly toxic […] More…

Elaphe and McLaren Applied partner up to produce high-response in-wheel EV drive


Elaphe and McLaren Applied are collaborating to provide an in-wheel propulsion system, coupling McLaren Applied’s inverter technology with Elaphe’s direct-drive in-wheel motors and vehicle controls. The combination is said to give a torque response five times faster than existing systems. Elaphe has demonstrated an energy efficiency of more than 97% on vehicles such as the […] More…

Kleanbus completes build of first repowered bus


Bus power conversion company Kleanbus has developed its first modular electric platform. Its ‘e-drivetrain in a box’ can convert a single- or double-decker bus from IC engine power to fully electric. Installed in an Optare Solo, the company is now entering pilot trials with bus fleet operators. In general, the conversion consists of a full […] More…

Tevva receives whole-vehicle type approval for its 7.5 tonne e-truck


EV manufacturer Tevva has become the first British company to receive European Community Whole Vehicle Type Approval (ECWVTA) for its 7.5 t battery-electric truck. It allows the company to start producing and selling the truck in volume across the UK and Europe. The first trucks have started to be delivered to customers including Expect Distribution, […] More…

Motor mode programming made easy


Synchronising motors and controllers is a key aspect of EV powertrain development, and Friwo’s electrification kits come with an algorithm that automates that potentially tricky process while enabling vehicle developers to program in their own modes to tailor motor output for economy or performance, for example (writes Peter Donaldson). Motors and controllers need synchronising to […] More…

Battery testing


The inside story  Nick Flaherty explains the various non-invasive methods of analysing the workings  of battery cells and their materials Testing battery cells, modules and packs presents a series of challenges. First of these is that taking measurements of the current and voltage changes the state of charge (SoC) of the cell and has an […] More…

Three-wheeler given new design


White Motorcycle Concepts (WMC) has started production of a new design of its electric-hybrid three-wheel scooter (writes Nick Flaherty). The WMC300FR uses a patented Venturi duct technology added to a Yamaha Tricity 300 platform with a 292 cc single-cylinder four-stroke motor. The hybrid power-assist unit consists of two 56 V, 12 Ah detachable lithium-ion rechargeable […] More…

Polymers confer safety and comfort


Ascend Performance Materials has developed two materials for EVs that improve safety and passenger comfort (writes Nick Flaherty). The Starflam X-Protect and Vydyne AVS tackle two key challenges automakers face when developing EV platforms. Starflam X-Protect is a flame-retardant nylon 66 that withstands exposure to 1 100 ºC direct flame for 15 minutes, surpassing standard flame-retardant materials and aluminium […] More…
