Abstract
Disclosed is an extended-range full-electric low-speed tractor, which includes a system control unit, a battery pack, a frequency conversion driver, a bidirectional DC-DC converter, a generating set and a drive system. The generating set is capable of working in an intermittent mode. The generating set will be started when the power of the battery pack is lower than a preset working range; once the generating set begins to work, the generating set will be running under a condition of “the most economic fuel consumption” and provide stable output at constant speed and constant power, so as to make sure that the generating set is not overloaded, emits no black smoke and has highest energy efficiency. It has advantages of low energy consumption, low pollution and long life of the generating set.
