Problems solved by technology

[0003] However, considering the distance limit of charging piles and emergency failure of battery packs, a single battery pack can no longer meet the needs of electric vehicles.
However, if multiple battery packs are used, the system structure of electric vehicles needs to be redesigned, and it is difficult to apply to electric vehicles with a single battery pack already in use.

Abstract

The invention provides a method and device for charging and discharging a multi-source battery pack, an electronic device and a storage medium. The method for charging and discharging the multi-sourcebattery pack comprises the following steps of: receiving fault information and residual power of multiple battery packs through multiple battery controller; determining an unfailed battery pack according to the failure information of the multiple battery packs; determining one or more quasi-power supply battery packs of which the residual electric quantity is greater than or equal to a preset electric quantity threshold value according to the determined residual electric quantity of the unfailed battery packs; determining a power supply battery pack from the one or more quasi-power supply battery packs; using the output signal of the battery controllers in communication connection with the power supply battery pack as the input signal being input into a functional module, using the outputsignal of the functional module as the input signal of the battery controller in communication connection with the power supply battery pack. The method and device achieve charging and discharging ofthe multi-source battery pack.

Description

technical field [0001] The invention relates to the field of charging and discharging of vehicles, in particular to a charging and discharging method, device, system, electronic equipment, and storage medium of a multi-source battery pack. Background technique [0002] Currently on the market, the electric vehicle power system solution is mainly a single battery pack, combined with other high-voltage components (motor, motor controller, charger, etc.), the control architecture of the power system is generally a single battery controller, a vehicle controller and other Controllers interact with each other. [0003] However, considering the distance limit of charging piles and emergency failure of battery packs, a single battery pack can no longer meet the needs of electric vehicles. However, if multiple battery packs are used, the system structure of electric vehicles needs to be redesigned, and it is difficult to apply them to electric vehicles with a single battery pack al...
