一种混合动力车的发电控制方法、设备及系统
摘要：
本发明提供了一种混合动力车的发电控制方法，所述混合动力车包括发动机系统和电池，所述发动机系统包括发动机和发电机，所述方法包括：设置第一阈值和第二阈值；获取电池温度和发电机温度；将所述电池温度与所述第一阈值进行比较，将所述发电机温度与所述第二阈值进行比较；如果所述电池温度大于所述第一阈值或者所述发电机温度大于所述第二阈值，则控制所述发电机系统工作在降功率发电模式；否则，控制所述发电机系统工作在高效发电模式。本发明通过合理控制发动机系统的发电模式，从而延长电池、发电机和发动机的使用寿命。
摘要（英）：

The invention provides a power generation control method of a hybrid vehicle. The hybrid vehicle includes an engine system and a battery; and the engine system includes an engine and a power generator. The power generation control method includes: setting a first threshold and a second threshold; acquiring the battery temperature and the power generator temperature; comparing the battery temperature and the first threshold, and comparing the power generator temperature and the second threshold; controlling the power generator system to work in a power reduction generation mode if the battery temperature is greater than the first threshold or the power generator temperature is greater than the second threshold; otherwise, controlling the power generator system to work in a high efficiency power generation mode. The service life of the battery, the power generator and the engine is prolonged by reasonably controlling the power generation mode of the engine system.
