How A Trinity Bradfield Prize Winner is Disrupting the Electric Car Industry

Batteries and suitable electrical machines are some of the key problems facing electric cars today, and Trinity Bradfield Prize winner, Saikat Subhra Ghosh might be the man to solve this. He aims to not only solve these problems but, in the process, make electric cars more economically viable than traditional cars. Saikat is a PhD graduate from the University of Cambridge and recently won first prize in the Trinity Bradfield Prize, which awarded him three months free space in the Bradfield Centre to experience and grow within its entrepreneurial culture, plus £10,000 in prize money.


His research is revolutionary for the industry as a car needs high torque when accelerating but low torque when cruising at high speeds. Electric cars currently do this by mostly employing an oversized electrical machine with conventional control, or in a few cases by changing gears, as there isn’t a wide enough torque-speed range for the existing machines. This is where Saikat comes in. He’s proposing an electric machine and control system capturing the whole range of torque, which can completely do away with the gearbox, reducing the space required and making the care more cost-effective. This technology has the potential to cut the price of electric vehicles drastically, making them more affordable than their conventional counterparts.


Saikat is passionate about his project and strongly feels this is the sector to be in, saying “If you want to do the cool stuff, just jump into it, as this is where the fun happens”. This is one of the reasons why Saikat is excited to be in the Bradfield Centre. “Here you can see an idea develop from lab to business, and I hope to learn more about becoming an entrepreneur and being able to describe my product and vision more effectively.”


The advice Saikat gives to students aspiring to be in the same position as him is to always come up with a new idea and keep going, even if it doesn’t work the first time. “This century is very focused on innovation and entrepreneurship, and today Universities have a far greater entrepreneurial focus, so talk to them about your ideas and get their guidance.”
