Vehicle power battery pack management system integrated into electric vehicle instrument and control method thereof

Abstract

The invention relates to a vehicle power battery pack management system integrated into an electric vehicle instrument and a control method thereof, and belongs to the field of integrated management of power battery packs. The vehicle power battery pack management system comprises a parameter dynamic sampling module, a heat management module, a battery state calculation module, a battery chargingand discharging management module, an instrument panel liquid crystal display module and an interface. The battery charging and discharging management module is respectively connected with a controller area network (CAN) bus and the instrument panel liquid crystal display module through the interface. The instrument panel liquid crystal display module is connected with the CAN bus. The heat management module and the parameter dynamic sampling module are also respectively connected with the CAN bus. The control method is to monitor a battery state and faults through a control program. The power battery pack management system is convenient to maintain when integrated into the electric vehicle instrument; the work reliability of the system is improved; a remote control interface of an instrument panel can change the management strategy at any time according to the working state of a power battery pack so as to guarantee that the battery pack operates in the optimal state and prolong the service life of a motor.

Description

technical field [0001] The invention relates to a management system and control method for a vehicle power battery group integrated in an electric vehicle instrument, belonging to the field of comprehensive management of the power battery group. Background technique [0002] Nowadays, as the world's global oil energy reserves are shrinking day by day, the auto industries of various countries have adjusted their strategic goals to the research and development of electric vehicles in order to cope with the inevitable oil energy crisis in advance. Of course, there are many technical problems that follow, such as Selection of motor, selection of power battery pack, maintenance of power battery pack, etc. [0003] In my country, due to the implementation of the national energy-saving and emission-reduction policy, various automobile manufacturers have also followed the international trend and turned to the production and research and development of electric vehicles, but the most...

Problems solved by technology

After retrieval and investigation, the current domestic battery management system is mostly a fixed module, its anti-interference ability is relatively lacking, the variability is poor, and the management mode is relatively simple. The so-called battery pack maintenance lacks flexibility and effectiveness. A large number of batteries are scrapped ahead of time due to the inconsistency of the battery pack, which not only increases the production cost, but also seriously wastes resources and pollutes the environment
