Problems solved by technology

[0002] The power battery is one of the core components of new energy vehicles, and the power battery may be severely degraded after a certain period of time. At this time, a new battery pack needs to be replaced, but the information of the existing battery pack is written directly during the production process. Into the program of the battery management system (BMS) hardware, and the BMS in the vehicle is generally not replaced. If the information of the new battery pack is to be loaded into the chip of the BMS after replacing the new battery pack, then every time it is replaced The battery needs to be flashed again, which will have certain risks

Abstract

The embodiment of the invention discloses a method and system for obtaining battery information. The method comprises the following steps: after a connection is established between a battery and a battery management system in a vehicle, obtaining identification information of the battery stored in a storage unit through the battery management system; and verifying whether the identification information of the battery is valid through a charging application client, so that when the identification information of the battery is valid, a charging device connected to the battery charges the batterybased on charging parameters configured in the charging application client. By adoption of the method and system provided by the embodiment of the invention, the identity verification between the battery and the battery management system in the vehicle is achieved, and by adoption of the charging application client, the battery is charged by the charging application client bound based on the battery.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a method and system for acquiring battery information. Background technique [0002] The power battery is one of the core components of new energy vehicles, and the power battery may be severely degraded after a certain period of time. At this time, a new battery pack needs to be replaced, but the information of the existing battery pack is directly written in the production process. Into the program of the battery management system (BMS) hardware, and the BMS in the vehicle is generally not replaced. If the information of the new battery pack is to be loaded into the BMS chip after replacing the new battery pack, then every time The battery needs to be flashed again, which will have certain risks. Contents of the invention [0003] Embodiments of the present invention provide a method and system for acquiring battery information. [0004] According to an aspect of an embod...
