METHODOLOGY TO ASSESS THE IMPACT OF DRIVING SCHEDULES AND DRIVE TRAIN CHARACTERISTICS ON ELECTRIC VEHICLE RANGE

A methodology is described that combines the use of the battery Ragone (average power) and peak power characteristics, in a simple manner, to show which batteries and which drive train characteristics favor any one driving schedule over another, including the Federal Urban Driving Schedule (FUDS) and the SAE J227aD Urban Driving Schedule (SUDS). The methodology also reveals the energy remaining unused in the battery at the end of a dischrge when the vehicle fails the requirements of the driving schedule. The additional range achievable by relaxing the discharge terminating requirements of the driving schedule for limp home can be determined. The methodology shows why batteries that have high peak power capability, while giving greater range, generally have less home ability.
