An electric bike developed by Bath University competing in the 2019 Isle of Man TT ‘Zero’ race employed Bender insulation monitoring technology.
Bath Zero, the University of Bath’s zero emissions motorcycle team developed The Phoenix with the support of industry sponsors such as Bender. Team Bath zero competed in the 2019 SES TT Zero class for battery powered bikes, taking fourth place, hard on the heels of the dominant Japanese Mugen and Mirai professional teams.
Bender’s IR155 insulation monitoring device uses patented measurement technology to monitor insulation resistance on the AC motor and DC side of the bikes electrical drive system. It continuously measures insulation resistance between 0 and 10MΩ, signalling insulations faults even under the high system interferences caused by motor control processes, acceleration and energy recovery.
Bender first broke into the electric vehicle market through its pioneering partnerships with Formula 1 and Formula E racing cars and has built on that experience to deliver solutions widely used in hybrid and electric vehicles and transport including London hybrid-powered Boris buses. For over a decade, the Bender Group has supported electric and hybrid vehicle development, to minimise the risk of electric shock, vehicle failure and to deliver early warning of electrical faults.
Team Bath Zero developed The Phoenix race bike including chassis, battery modules, electronics, sensors and carbon fibre fairings. Standard parts such as wheels, brakes and suspension members were donated by 30 industry sponsors.
The Phoenix completed the island’s 264-corner 37.5-mile course in 23 minutes 52 seconds, at an average speed of just under 95mph. It proved capable of reaching 100mph in nine seconds and hit a top speed of 162mph.
Prof Tony Miles, the Bath Zero Team’s academic supervisor said: ”This is a massive achievement by a team of six undergraduate final year students studying mechanical, electrical and integrated mechanical and electrical engineering courses, hugely assisted by university technical support staff.”
The TT Zero event is a proving ground for the concept of electric bikes that have proved capable of delivering 300 peak bhp and 500 Nm of torque available from 0 to 4500 rpm, hugely exceeding the power available from petrol driven bikes. Advances in battery technology are the key to commercial production of the electric bikes. The Bath Zero’s battery package is designed to deliver its full charge over a single 37.5-mile lap but in normal use the bike could have a range of up to 250 miles.
The team will be reformed for next season with a new group of students who will develop a new bike and continuing to race The Phoenix.
The Bender Group is committed to the development and investment in new technology for electric and hybrid vehicle and charging technology and supports over a hundred and fifty student race teams globally.
