Problems solved by technology

Most of the battery systems in vehicles do not have an encryption verification function for the use of batteries (such as charging, discharging, obtaining battery status, etc.), so that the battery system will be disassembled at will and used in disorder; and, although the battery systems in some vehicles are equipped with encryption Verification function, but it does not have the function of unique identification of battery products. The password or ID can be obtained and modified by the outside world, and the identification effect on the integrity of the battery is poor. Use safety issues and the loss of battery pack manufacturers are also not conducive to the secondary recycling and cascade utilization of battery packs

Abstract

The embodiment of the invention discloses a battery use verification method, a battery system and an automobile. The method comprises the steps of acquiring a first secret key value corresponding to abattery; acquiring identification information of the battery, and using a preset encryption algorithm to perform encryption computing on the identification information to acquire a second secret keyvalue; comparing the first secret key value with the second secret key value, and determining whether a battery use request passes verification based on a comparison result; and if verification is passed, executing the operation. According to the method, the battery system and the automobile provided by the invention, a secret key verification link is set for the use of the battery, and after verification is successful, the battery can be normally used; a block chain technology is used for storing data such as a secret key, the condition that the secret key is not modified and stolen is ensured, reliable insurance is provided for uniqueness recognition of the battery, and potential safety hazard caused by dismounting of the battery or separated use of a battery module and a battery managerare prevented.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery usage verification method, a battery system and an automobile. Background technique [0002] In the new energy electric vehicle industry and new energy storage technology, batteries play a key role. At present, people's demand for batteries is also increasing. Reasonable use of batteries is related to the safety of electric vehicles during use and the service life of battery systems. Most of the battery systems in vehicles do not have an encryption verification function for the use of batteries (such as charging, discharging, obtaining battery status, etc.), so that the battery system will be disassembled at will and used in disorder; and, although the battery systems in some vehicles are equipped with encryption Verification function, but it does not have the function of unique identification of battery products. The password or ID can be obtained and modified by th...
