    • A work machine (10) comprises a first power unit (12) couplable with a first primary load (18); a first temperature sensor (41) associated with said first power unit (12) and providing a first output signal; a second power unit (14) mechanically independent from said first power unit; a second temperature sensor (45) associated with said second power unit and providing a second output signal; a first motor/generator (22) mechanically coupled with said first power unit (12); a second motor/generator (30) mechanically coupled with said second power unit (14) and electrically coupled to said first motor/generator (22); and at least one electrical processing circuit (50) coupled with the temperature sensors (41, 45) and the motor/generators (22, 30). The electrical processing circuit (50) is configured for selective bidirectional transfer of electrical power between the motor/generators (22, 30), dependent on said first output signal and said second output signal.
    • 工作机器(10)包括可与第一主要负载(18)联接的第一动力单元(12)。 与所述第一功率单元(12)相关联并提供第一输出信号的第一温度传感器(41) 与所述第一动力单元机械独立的第二动力单元(14); 与所述第二功率单元相关联并提供第二输出信号的第二温度传感器(45) 与所述第一动力单元(12)机械联接的第一电动机/发电机(22)。 与所述第二动力单元(14)机械耦合并电耦合到所述第一电动机/发电机(22)的第二电动机/发电机(30)。 以及与所述温度传感器(41,45)和所述电机/发电机(22,30)耦合的至少一个电处理电路(50)。 电处理电路(50)被配置用于根据所述第一输出信号和所述第二输出信号在电动机/发电机(22,30)之间选择性地双向传输电力。
