An electric tractor is provided with a vehicle body, an electric motor, a battery, a converter for controlling the input/output power of the battery, wheels for traveling, and a control device. The control device controls the converter such that the input/output power of the battery is within a predetermined prescribed power range, if the electric tractor is traveling within a predetermined restricted area. The control device determines whether or not the electric tractor is likely to move from the restricted area to the outside of the restricted area. When a positive determination is made in the determination process during the restriction process, the control device expands the predetermined power range compared with when a negative determination is made in the determination process.
电动牵引车具备车身、电动机、电池、控制电池的输入输出电力的转换器、行驶用的车轮、以及控制装置。控制装置以电动牵引车正在预先确定的限制地区内行驶作为条件之一,控制转换器以使得电池的输入输出电力成为预先确定的规定电力范围内。控制装置判定电动牵引车是否有可能从限制地区向该限制地区之外移动。在限制处理的期间判定处理中做出肯定判定的情况下,与在判定处理中做出了否定判定的情况相比,控制装置扩大规定电力范围。
