本发明之电动二轮车包括电池、三相交流电动马达、马达控制器、由骑士操作之加速操作器、及检测加速操作器之操作量之加速操作检测机构。电动马达包含3相之线圈,且构成为于自电池供给电流时产生应传递至驱动轮之驱动力,于3相之线圈短路时产生特定之制动转矩。马达控制器包括:短路控制机构,其响应于预先规定之短路条件之成立,使3相之线圈短路而使电动马达成为短路状态;解除控制机构,其于电动马达为短路状态时,响应于预先规定之解除条件之成立而解除短路状态;以及回充控制机构,其于借由加速操作检测机构所检测出之加速操作器之操作量为零时,运行将电动马达所产生之回充电流供给至电池之回充动作。回充控制机构于借由解除控制机构而解除短路状态时,以使电动马达产生与3相短路状态时同等之制动转矩之方式控制回充电流。

Provided is a two-wheeled electric vehicle that includes a battery, a three-phase alternating current electric motor, a motor controller, an accelerator operator, and an accelerator operation detection means. The electric motor is constructed so as to generate driving force to be transmitted to a drive wheel when current is supplied from the battery, and to generate a prescribed braking torque when the three-phase coil short-circuits. The motor controller includes: a short circuit control means that places the electric motor in the short-circuited state when short-circuiting conditions are met; a release control means that releases the short-circuited state when release conditions are met while the electric motor is in the short-circuited state; and a regeneration control means that executes a regeneration operation whereby regenerative current generated by the electric motor is supplied to the battery when the operation amount of the accelerator operator is zero. When the short-circuited state is released by the release control means, the regeneration control means controls the regenerative current such that the electric motor generates the same braking torque as during the three-phase short-circuited state.
