    • A hybrid electric locomotive (100) according to an embodiment includes an internal combustion engine (1), a dynamo (2), a converter (3), an inverter (5), a direct current link (4), a battery (8), a first map (T1), and a controller (9). The dynamo (2) is connected with the internal combustion engine (1) and capable of converting power of the internal combustion engine (1) into alternating current power. The converter (3) is connected with the dynamo (2) and capable of converting the alternating current power of the dynamo (2) into direct current power. The inverter (5) is capable of converting the direct current power into alternating current power. The direct current link (4) connects the converter (3) and inverter (5). The battery (8) is electrically connected with the direct current link (4). The first map (T1) stores therein a correspondence relationship between an upper limit of output power of the battery (8) and a temperature and a state of charge of the battery (8). The controller (9) controls the internal combustion engine (1) and the dynamo (2) in accordance with the temperature and the state of charge of the battery (8) so that the output power of the battery (8) is not higher than the upper limit stored in the first map (T1).
    • (1),发电机(2),转换器(3),逆变器(5),直流链路(4),电池(8) ),第一图(T1)和控制器(9)。 发电机(2)与内燃机(1)连接并能够将内燃机(1)的动力转换成交流电力。 转换器(3)与发电机(2)连接,能够将发电机(2)的交流电转换为直流电。 逆变器(5)能够将直流电力转换成交流电力。 直流链路(4)连接转换器(3)和逆变器(5)。 电池(8)与直流链路(4)电连接。 第一映射(T1)在其中存储电池(8)的输出功率的上限与电池(8)的温度和充电状态之间的对应关系。 控制器(9)根据电池(8)的温度和充电状态控制内燃机(1)和发电机(2),使得电池(8)的输出功率不高于 存储在第一映射(T1)中的上限。
