Onboard charger gives it 300%

Finepower has developed an onboard charger based on gallium nitride which, at 3 kW/litre, exceeds the power density of conventional chargers by 300% (writes Nick Flaherty). The water-cooled charger measures 210 x 50 x 60 mm without the housing, and converts input voltages from 85 to 264 V AC, with a maximum power of...

Scoping out motors/inverters

The accurate analysis of inverter waveforms without interference from switching noise is a key part of evaluating the motor drive circuit, driving the need for a class of test equipment called a ScopeCorder (writes Nick Flaherty). Between 16 and 18% of the total power in an electric car is consumed as losses in the...

E-axle promises lower losses

JLG is developing an electrified aerial lifting platform using electrified axle technology from Dana (writes Nick Flaherty). Dana’s design reduces power losses by up to 20% compared with traditional diesel-powered drivetrains. Dana has developed two approaches to hybridisation and electrification. The first is to use electrified drive systems that fit within current vehicle architectures; the second is...

BMW/Jaguar e-drive

BMW is to work with Jaguar Land Rover (JLR) to develop next-generation electric drive units that reduce the use of rare earth elements (writes Nick Flaherty). BMW’s fifth-generation powertrain, called eDrive, combines the electric motor, transmission and power electronics in one housing, and the company says it has eliminated the need for rare earth elements for...
