Hybrid vehicle energy management method, device and equipment and storage medium

The invention provides a hybrid vehicle energy management method, device and equipment and a storage medium, and relates to the technical field of vehicles. According to the method, the vehicle power demand and the current battery capacity of the hybrid vehicle are obtained, and when the current battery capacity is larger than the battery capacity lower limit value and the vehicle power demand is larger than the engine operation power lower limit, the power distribution coefficient lambda of the hybrid vehicle in the hybrid operation mode is determined according to the power source system efficiency; the power distribution coefficient lambda is used for indicating power distribution of an engine and a battery, the hybrid vehicle is controlled to operate in a sub-mode corresponding to the power distribution coefficient lambda according to the power distribution coefficient lambda, and different lambda corresponds to different sub-modes. According to the hybrid vehicle energy management method provided by the i
