Abstract

The present invention provides an energy management method, system, device and storage medium for a vehicle-mounted dual-source battery pack, wherein the energy management method for a vehicle-mounted dual-source battery pack includes: selecting one of the battery packs according to the battery status of the first battery pack and the second battery pack Once the motor controller is powered on to drive the motor to rotate, the battery status includes fault status, high voltage status and whether the remaining power exceeds the preset power threshold. The invention can expand the scope of application of the dual-source battery pack, improve the convenience of the dual-source battery pack, and improve the cruising range under the premise of ensuring power, economy, and driving performance, and greatly reduce the cost of the battery pack and the cost of the entire vehicle. the cost of.

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...
