Abstract
A charge-or-start system applied in an electric vehicle is provided. The charge-or-start system includes a charge-or-start device coupled to an external power source, an on-car electric source coupled to the charge-or-start device and a battery unit coupled to the charge-or-start device for storing and providing power. In charge mode, under control of the charge-or-start device, anyone of the external power source and the on-car electric source provides power to the battery unit for charging the battery unit through the charge-or-start device. In starting mode, under control of the charge-or-start device, the battery unit provides power to the on-car electric source for activating the on-car electric source through the charge-or-start device.
