Battery information acquisition device, system and method

Abstract

The invention discloses a battery information acquisition device, system and method. The battery information acquisition device comprises a positive electrode connecting piece used for connecting a positive electrode of a battery, a cathode connecting piece used for connecting a negative electrode of the battery, a power supply module used for realizing power taking of the battery information acquisition device from battery positive and negative electrodes, an information acquisition module used for acquiring working information of the battery, a data storage module used for storing the working information of the battery and storing environment information sent to the battery information acquisition device by a transfer module, and a wireless communication module used for sending the working information and the environment information to the transfer module. According to the battery information acquisition device, the battery can be directly used for providing power to monitor and analyze the information of the whole life cycle of the battery; in addition, the transfer module can send the detected environment information to the battery information acquisition device, so that the environment information can be prevented from being lost when communication is interrupted.

Description

technical field [0001] The invention relates to the technical field of lithium battery monitoring, in particular to a battery information collection device, system and method. Background technique [0002] With the development of social economy, more and more power batteries are applied to electric vehicles such as electric vehicles, electric trains and electric bicycles to provide power sources for vehicles. In view of the wide application of power batteries, it is particularly important to continuously monitor the information of power batteries, which is not only conducive to monitoring the safe use status of power batteries, but also conducive to the cascade utilization of power batteries. In the prior art, there is no method for continuous monitoring of power battery information and statistical analysis of data, and it is impossible to effectively collect and monitor the information of the whole life cycle of the power battery, and thus cannot effectively guarantee the s...

AI Technical Summary

Problems solved by technology

[0008] 1. The battery information is not comprehensive enough, which is not conducive to the evaluation of battery status, is not conducive to the improvement of battery technology and the cascade utilization of batteries;

[0009] 2. Because the state and life of the power battery are affected by temperature factors during storage and use, the system does not fully collect temperature information for the entire life cycle of the battery;

[0010] 3. The traceability management system has not updated the relevant data information after the product is shipped;

[0011] 4. The traceability system and monitoring platform of various battery information management schemes have incomplete information, and it is impossible to save and monitor the information of the battery life cycle from production to scrap;

[0012] 5. Information collection or monitoring methods are not sufficiently automated and intelligent;

[0013] 6. The status information of other batteries for non-electric vehicle operation or cascade utilization batteries is easily interrupted or terminated
