HEAT IS THE BIG­GEST EN­EMY OF PER­FOR­MANCE

Motorcycle News (UK) - - Sport -

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.”
