  • This paper describes system definition of the extended range EV and presents cruising strategy of EV mode and ER mode. Also high voltage battery strategic SOC could be indicated and compared depends on various generator working cycles. A C-segment SUV has been produced and carried out cruising test in order to validate on highway, city and hill climbing road. This paper shows advantages and disadvantages of SOC variation on each road environments and presents the strategies as the cruising test results. On the basis of the test result, this paper suggests future works and research directions for strategy of battery management to extended range EV.

  • For testing a two-wheeled vehicle's per-charge range, this study conducted road and chassis dynamometer driving tests. Three typical road routes within Daejeon Metropolitan City were selected for the road-driving test. In the case of CVS-40 mode driving tests using a chassis dynamometer, various road-loading conditions were set. In this study, two-wheeled electric vehicles' per charge range on the road was confirmed through testing, and the range and energy consumption efficiency depending on various chassis dynamometer road load settings were measured. Then, the results of the actual road driving tests were compared with those of the chassis dynamometer driving tests, and road load settings that yielded per-charge range testing results similar to those under actual road driving conditions in the chassis dynamometer experiments were studied.
