The global provider of machine-to-machine and IoT connectivity products and services, Digi International, is highlighting its role in the development of a new zero-emissions-capable black cab operating in London.

The Ecotive’s Range Extended Electric (REE) Metrocab core powertrain and infotainment systems, which have been developed by Frazer-Nash Research, use the Digi ConnectCore® 6 (Digi CC6) System-on-Module to drive the Metrocab’s entire driver instrumentation and passenger displays.  Frazer-Nash utilizes the Digi CC6 in two key areas – first in processing information from the drivetrain to the instrument display, and secondly in providing wireless connectivity to deliver real-time information, application updates and a more interactive driver and passenger experience.

The taxi is driven by two electric motors with a 1-litre petrol engine coupled with a generator (the range extender) which charges the battery pack.  Alternatively, charging can be achieved via any mains outlet, ensuring an even lower fuel consumption.  This unique configuration, and the sophistication of the powertrain, allows the driver many charging options to maximize their efficiency.  The Digi CC6 has been designed to provide a fuller array of instrumentation to assist cost-conscious taxi drivers in choosing the best operation.

Digi International says information that the Digi CC6 processes and presents to taxi drivers includes:

  • Vehicle use information: drive mode, speed, energy flows, watt hours per kilometer, detailed range and fuel economy displays (electric, petrol), battery state of charge, steering angles, and torque curves, as well as standard information such as tire pressure, oil temperature, seat belt warnings, and more.
  • Trip information: Time of trip, distance, GPS, level of emissions.
  • General information: time, inside temperature, outside temperature, location via GPS, and live weather reports.
