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 […]

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 […]
