Abstract

The invention provides an energy management method, system and equipment of a vehicle-mounted dual-source battery pack and a storage medium. The energy management method of the vehicle-mounted dual-source battery pack comprises the steps that one of a first battery pack body and a second battery pack body is selected according to battery states of the first battery pack body and the second batterypack body to electrify a motor controller, a motor is driven to rotate, and the battery states comprise a failure state and a high voltage feeding state, and whether the residual electric quantity exceeds the electric quantity of a preset electric quantity threshold value or not is further included. According to the energy management method, system and equipment of the vehicle-mounted dual-sourcebattery pack and the storage medium, the range application range of the dual-source battery pack can be expanded, and the conveniences of the dual-source battery pack are improved; and under the premise of ensuring the dynamic property, the economical efficiency and the driveability, the endurance mileage is improved, and the battery pack cost and the total vehicle cost are greatly reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicle battery management, in particular to an energy management method, system, device and storage medium for a vehicle-mounted dual-source battery pack. Background technique [0002] At present, electric vehicles generally adopt two methods to meet the requirements of large-power battery packs: [0003] (1) Increase the capacity of a single cell, such as Samsung's 96Ah ternary lithium-ion battery. Although the capacity of the single cell is increased, the increase in capacity will inevitably lead to an increase in the space occupancy rate, which will greatly restrict the utilization of the battery space of the vehicle, and when designing the battery pack, the large-capacity cell Body cells are not easy to combine at will, which makes the expandability of the battery pack poor and cannot adapt to different mileage requirements. [0004] (2) Use a large number of small-capacity single cells: for examp...
