Embodiment Construction

[0018] In order to facilitate those skilled in the art to understand, the present invention will be described in further detail below in conjunction with embodiment:

[0019] A BMS host computer program authorization confidentiality method, the method comprises the following steps:

[0020] (1). The user PC installs the upper computer program and obtains authorization through the authorization code;

[0021] (2). The host computer program reads the PC hardware information, generates a hardware identification code, puts the hardware identification code in the authorization code, and then stores the new authorization code in the host computer program together;

[0022] (3). The PC connects to the BMS for the first time, and the BMS compares the authorization code information interactively through the host computer program to confirm whether the PC is legally authorized. If it is legally authorized, the BMS stores the hardware identification code stored in the host computer p...

Abstract

The invention discloses an authorization encryption method of an upper computer program of a BMS (Battery Management System). The authorization encryption method comprises the following steps that: a user PC (Personal Computer) is installed with the upper computer program and obtains authorization through an authorization code; the upper computer program reads hardware information of the PC, generates a hardware identification code, puts the hardware identification code in the authorization code and stores a new authorization code in the upper computer program; the PC is connected to the BMS for the first time, the BMS interactively contrasts the authorization code information through the upper computer program and confirms if the PC is legally authorized; and when the BMS is needed to be connected to be written and read, the PC is connected to the BMS to start up the upper computer program, and the BMS checks if the upper computer program is legally authorized. The authorization encryption method of the upper computer program of the BMS can protect the upper computer program technology and use right thereof efficiently, prevent an authorization code file from being decrypted maliciously and reduce a risk of software imitation.

Description

technical field [0001] The invention relates to the improvement of BMS security technology. Background technique [0002] At present, the battery management system and its upper computer used in electric vehicles have no security measures. Anyone who can copy the upper computer to his own PC can communicate with the battery management system and read the voltage, capacity, and temperature of the corresponding battery. And parameters such as temperature rise, which will cause leakage of battery management system technology and battery technical indicators, causing losses to battery management system manufacturers and battery manufacturers. [0003] Currently, the frequently used authorization technologies in software include: hardware lock technology and authorization code technology. [0004] Hardware locking technology: It is often used to prevent software from being copied. At present, most hardware such as the MAC address of the network card of the user's PC, the serial ...
