Abstract

The invention discloses a portable battery management system diagnosis apparatus, which comprises a control module. The control module comprises a micro-control unit for receiving information, processing data and sending signals. The micro-control unit is connected with a TF storage card for storing battery information, complete vehicle information and fault information through a serial peripheral interface; the micro-control unit is also connected with a first path of CAN communication for carrying out information interaction with a BMS (battery management system), and a second CAN communication for carrying out information interaction with a vehicle control unit; and the TF storage card is connected with a USB interface for connecting with an external computer. The portable battery management system diagnosis apparatus has the advantages of being small in size, convenient to hold and convenient for on-site diagnosis and debugging. The invention also discloses a working method of the portable battery management system diagnosis apparatus.

Description

technical field [0001] The invention relates to a portable battery management system diagnostic instrument and a working method thereof, belonging to the technical field of battery management system diagnosis and monitoring. Background technique [0002] Power batteries have been widely used in energy storage, electric vehicles and smart grids. In order to ensure the safe and long-term operation of batteries, a corresponding battery management system (Battery Management System, hereinafter referred to as BMS) needs to be equipped to detect the operating status of the battery in real time and perform charging. discharge management. The battery management system is generally installed inside the battery box. When the battery system or BMS fails, there will be problems in fault detection and program update. [0003] At present, the commonly used fault detection and program update must be realized through the CAN bus through the laptop and the host computer software, and some e...
