Abstract

Provided is an automobile power battery monitoring system and a monitoring method thereof. The automobile power battery monitoring system comprises a vehicle-mounted terminal, a remote monitoring center, and an external computer. The vehicle-mounted terminal comprises an acquisition module set, a battery management system master control module, and a debugging interface module. The acquisition module set acquires battery working condition parameters in a real-time manner. The battery management system master control module carries out analysis and processing of the acquired battery working condition parameters. The debugging interface module comprises a wireless emission interface, a wireless reception interface, a data access interface, and a function debugging interface. When an automobile is moving, the wireless emission interface and the wireless reception interface are used for bidirectional data communication between the vehicle-mounted terminal and the remote monitoring center in a wireless mode. When the automobile is stopped, the data access interface and the function debugging interface are used for wired data communication and system debugging between the vehicle mounted terminal and the external computer.

Description

technical field [0001] The invention relates to an automobile power battery monitoring system, in particular to an automobile power battery monitoring system and a monitoring method. Background technique [0002] Exhaust pollution from motor vehicles has become a major problem of urban environmental pollution and climate deterioration. New energy vehicles, such as pure electric vehicles and hybrid vehicles, are increasingly being valued and vigorously promoted by the automotive industry. [0003] The power battery system is an important part of the vehicle, providing electrical energy for the operation of the electric vehicle. The power battery is an important energy storage component of the vehicle. The working voltage of the power battery is generally above 300V. By adopting a higher voltage specification, the working current of the electrical equipment can be effectively reduced, and the weight of the electrical equipment and the vehicle can be reduced. However, the work...
