Abstract

The present invention provides a multi-source battery pack charging and discharging method, device, electronic equipment, and storage medium. The multi-source battery pack charging and discharging method includes: receiving fault information and remaining power of multiple battery packs through multiple battery controllers; Determine non-faulty battery packs according to the fault information of multiple battery packs; determine one or more quasi-power supply battery packs whose remaining power is greater than or equal to a predetermined power threshold according to the determined remaining power of the non-failure battery packs; determine from one or more quasi-power supply battery packs Determine the power supply battery pack in the power supply battery pack; use the output signal of the battery controller connected to the communication connection of the power supply battery pack as an input signal to the functional module, and use the output signal of the functional module as the power supply battery pack The input signal of the communication link to the battery controller. The method and device provided by the invention realize charging and discharging of multi-source battery packs.

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...
