Battery power requirements in high-performance electric vehicles

International standards and guidelines regarding characterisation and cycle life testing of batteries in electric vehicles (EVs) currently do not take into account high-performance driving. Using simulation software, track driving in a high-performance vehicle is simulated, and speed-time profiles are recorded. These as well as established driving cycles are used in conjunction with an EV model to determine power profiles at battery terminals. The difference in the resulting power profiles suggest that the evaluation of batteries for the HP segment requires separate characterisation and cycle life tests.
