The head of EV strategy at ePropelled tells Rory Jackson how he came into the role, and shares details of the company’s dynamic torque switching technology Talking the torque P redicting growth or decline across different areas of the e-mobility world is challenging at the best of times. These days it is even more complex, with major evolutions sorely needed across systemic factors such as vehicle r&d, material supply chains and worldwide energy and transport infrastructure, to pave the way for full replacement of IC engines with zero-emissions powertrains. These factors must be closely watched and understood to enable informed decisions on new investments across manufacturing, research and joint ventures. Vehicle OEMs need to move in step with these forces to safeguard their assets and strategic decisions in the new automotive age. And ePropelled’s head of EV strategy, David Hudson, knows that need first hand. His career spans more than 40 years across a number of major names in the automotive world. For the most part of the past 20 years he was particularly prominent in the technical leadership of Tata Motors, managing much of that vast organisation’s r&d and guiding it towards electrification technologies. Earlier this year, he moved from Tata to the rapidly growing ePropelled, an electric motor company already acclaimed in the UAV world for the high efficiency of its products. The company is now making strides in the EV space thanks to its recently unveiled electric dynamic torque switching (eDTS) technology. Starting at Jaguar Hudson’s earliest inspirations and career steps were in the realm of traditional IC engine mobility. A childhood love of cars culminated in him signing up for a mechanical engineering undergraduate programme at the highly automotive-focused Lanchester Polytechnic (now Coventry University) in England, in the mid-1970s. “I’d had interviews with and been offered university sponsorship by several groups then known as members of British Leyland, but eventually I chose Jaguar [the Large Car division of British Leyland at the e7ropelleK»s e+;: Totors stanK to Nreatly enOance E= eɉciencies anK +a]iK /uKson is to o]ersee tOeir supply anK continueK r K (Courtesy of e7ropelleK) 16 Winter 2021 | E-Mobility Engineering
