With the continuous expansion of the application fields of lithium batteries, the market demands of lithium batteries are also continuously expanding.

The inventors have noted that thousands of lithium battery packs are stored in a lithium battery warehouse for a long period of time, and maintenance such as power replenishment and balancing is required for the lithium battery packs in the warehouse because the lithium battery packs have self-discharge characteristics. In the traditional technical scheme, a warehouse worker regularly performs maintenance such as electricity supplementing, balancing and the like on all lithium battery packs in a warehouse; the lithium battery packs in the warehouse are large in number and dense in storage, the traditional process of maintaining the lithium battery packs is blindly, the workload is huge, and a large amount of manpower and material resources are wasted.

In order to monitor the battery state of the lithium battery pack stored in the lithium battery warehouse, the inventor researches and discovers that the battery management system can detect the battery information of each battery cell in the lithium battery pack, namely, the battery management system in the lithium battery pack can be utilized to acquire the battery information of the lithium battery pack, and then the acquired battery information is analyzed, so that the battery state of the lithium battery pack is monitored. However, the battery management system needs to transmit battery information of the lithium battery pack in the case of power supply; the lithium battery pack is directly in a working state to realize the power supply mode for the battery management system, so that a great deal of power resources are wasted.

More specifically, the memory may include a memory bank, a hard disk, a TF (Trans-flash Card) Card, a SD (Secure Digital Memory Card) Card, and the like, which are specifically selected according to actual requirements, and the embodiment is not limited thereto.

In this embodiment, by further storing the identity of the abnormal battery module and the corresponding detection time, it is possible to facilitate the staff to check the condition of monitoring the state of the external battery module, thereby further improving the use experience of the user.

On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, in this embodiment, the battery information includes the cell voltage, the temperature and the remaining power.

Wherein, the single voltage refers to the voltage corresponding to each battery single in the external battery module; the temperature refers to the temperature corresponding to each battery cell or the temperature of the appointed part of the external battery module; the remaining power refers to the entire remaining power corresponding to the external battery module.

In actual operation, after battery information such as single voltage, temperature and residual electric quantity of the external battery module is obtained, the battery manager of the external battery module sends the battery information to the information acquisition module, so that the information acquisition module sends corresponding battery information to the monitoring terminal, and the monitoring terminal can monitor the state of the external battery module according to the battery information such as the single voltage, the temperature and the residual electric quantity. Therefore, the monitoring terminal monitors the state of the external battery module, including monitoring whether the voltage and the temperature of the external battery module are normal or not, and whether the electric quantity is too low or not, so that the state of the external battery module is monitored comprehensively.

On the basis of the above embodiment, the technical scheme is further described and optimized in this embodiment, and in particular, in this embodiment, the information acquisition module is connected with the monitoring terminal through a wireless network.

In particular, the Wireless network may include WIFI (Wireless-Fidelity), a mobile cellular network, NFC (near field communication), and the like. In this embodiment, the information acquisition module establishes communication connection with the monitoring terminal through the wireless network, so as to send the battery information to the monitoring terminal through the wireless network after the battery information of the external battery module is acquired.

and the alarm module is connected with the monitoring terminal and used for sending abnormal battery prompt information which carries the identity of the abnormal battery module.

It should be noted that, the specific type of the alarm module is not limited in this embodiment; for example, the alarm module may include a voice player, a display, and the like, and the purpose of prompting the abnormal state of the abnormal battery module is achieved by voice information including the identity of the abnormal battery module sent by the voice player and/or text information or image information including the identity of the abnormal battery module sent by the display.

Therefore, the abnormal battery prompt information is sent out through the alarm module, so that the abnormal battery module of the staff is prompted to have abnormal state, and the staff can intuitively and conveniently know the battery state monitoring condition.

On the basis of the above embodiment, the technical solution is further described and optimized in this embodiment, and specifically, in this embodiment, the battery state monitoring system further includes:

It can be understood that when the power supply module is a dry battery, the power supply module gradually consumes the own electric quantity in the process of supplying power to the signal acquisition device and the battery manager; when the electric quantity of the power supply module is lower than the electric quantity threshold value, the power supply module cannot normally supply power to the signal acquisition device and the battery manager, so that normal operation of battery state monitoring is affected.

Therefore, the embodiment further provides a detection module, and the detection module is connected with the power supply module and is used for obtaining the residual electric quantity of the power supply module. The detection module may be a coulometer, or may be other devices, for example, a resistor is connected in series between the positive electrode and the negative electrode of the power supply module, and a corresponding voltage is calculated according to a resistance value and a current value flowing through the resistor, so as to determine a residual electric quantity of the power supply module corresponding to the power supply module. The specific type of the detection module is not limited in this embodiment.

The detection module sends the collected residual electric quantity of the power supply module to the monitoring terminal, and the monitoring terminal analyzes the residual electric quantity of the power supply module according to a preset analysis rule and judges whether the residual electric quantity of the power supply module is lower than an electric quantity threshold value or not; when the residual electric quantity of the power supply module is determined to be lower than the electric quantity threshold value, determining module information of the power supply module, and sending the module information to an alarm module; the alarm module generates corresponding power supply abnormality prompt information after receiving module information of the power supply module sent by the monitoring terminal, and sends the power supply abnormality prompt information; the power supply abnormality prompting information carries module information, so that the aim of prompting the working personnel that the electric quantity of a power supply module corresponding to the module information is too low is fulfilled.

Therefore, the embodiment further monitors the electric quantity of the power supply module, so that the situation that the battery state monitoring of the external battery module cannot be realized due to the fact that the electric quantity of the power supply module is too low is avoided, and the safe and reliable operation of the battery state monitoring system is ensured.
