posted on 2011-11-10, 10:01 authored by Anita Chaudhari, Rob ThringThis paper presents the data recorded from two G-Wiz Reva electric vehicles (EVs)
over a period of two years and approximately 8000km on each vehicle. The analysis of the
vehicle data demonstrates that the range of the vehicle obtained for a certain state-of-charge
(SOC) drop was not consistent. The results show that the main factor affecting the available
range was irregular vehicle usage. The recharge energy consumption patterns of the vehicle
were identified and it was demonstrated that infrequent vehicle usage increased energy consumed
by the vehicle. A maximum range of 66.8km was achieved when the vehicle was regularly
used, but this fell to 42.8km when it was infrequently used. The energy economy when
the vehicle was regularly used was 8.3 km/kWh. Additionally, the analysis results identify the
need to determine discharge rate of the vehicle batteries to determine the precise effects on
the available range and energy consumption of the vehicle.
