Automatic management device of lead-acid power batteries

Abstract

The invention discloses an automatic management device of lead-acid power batteries. The automatic management device comprises a data base, an acquisition module, an encryption and decryption module, a data processing module and a display, wherein the data base is used for storing digital certificates and maintaining the digital certificates in the data base via a management interface; the acquisition module is used for acquiring parameter data of the lead-acid power batteries by a two-wire system and uploading the parameter data to the data base; the encryption and decryption module is used for encrypting and / or decrypting the parameter data by using the digital certificates; the data processing module is used for paying the encryption and decryption module for separate passwords, receiving and processing the parameter data and then sending the processing results to the display; the display is used for receiving and displaying the processing results. The automatic management device has the beneficial effects that the parameter data is encrypted and / or decrypted by using the digital certificates so as to achieve safety management of the device, thus improving the safety of the automatic management device of the lead-acid power batteries.

Description

technical field [0001] The invention relates to an automatic management device, in particular to an automatic management device for lead-acid power batteries.

Problems solved by technology

[0009] During the research, the inventor found that due to the complexity of the charging and discharging process of the battery, the battery management system cannot monitor the voltage, current, temperature and charging and discharging of the battery throughout the process. Therefore, it cannot guarantee that the battery will not lose its life due to overcharging and overdischarging, and the battery management system cannot give a more accurate estimate of the battery's remaining capacity (SOC-State 0f Charge). Since the performance parameters are placed in the database, they will also Obtained at will, poor security
