HEAT IS THE BIGGEST ENEMY OF PERFORMANCE
Battery heat is electric racing’s big performance hurdle. An electric motorcycle motor that make 100kw creates a lot of heat, which is the biggest obstacle facing whoever builds Motogp’s electric racers.
“The issue isn’t battery capacity, but more the rate of discharge and heat management,” says Mugen’s Colin Whittamore. “The faster you pull/push energy out of/into a battery, the more heat is generated, which is why your mobile phone gets hot when it’s working hard.
“I expect there will be a ‘eureka’ moment when someone will come up with the next generation of battery, for want of a better word. Think back to early mobiles and their ‘satchel’ batteries, and the effect going from Nicad to lithium batteries had on power tools.”
