Embodiment 1

[0046] An intelligent lithium battery protection device, see figure 1 and Figure 5 , the protection device A is connected to the assembled lithium battery B (the lithium battery is composed of a plurality of single batteries C); the protection device includes: a microprocessor 1, an analog front-end circuit 2, an equalizing circuit 3, a MOS drive circuit 4, Data memory 5, antenna 6, and timing circuit (RTC) 7.

[0047] The analog front-end circuit 2 collects the total voltage, single group voltage, temperature, and current information of the lithium battery B (these information are collectively referred to as data information). The microprocessor 1 reads the data information collected by the analog front-end circuit 2 for analysis, judges the overcharge and overdischarge of the battery according to the single voltage of the battery to realize voltage protection; judges the high temperature and low temperature of the battery according to the temperature information of the bat...

Embodiment 2

[0062] A kind of control method of intelligent lithium battery protection device, see Figure 4 and Figure 5 , the control method includes the following steps:

[0063] 101: The external terminal device obtains the lithium battery data collected by the intelligent lithium battery protection device through Bluetooth technology, wifi technology, or infrared technology;

[0064] 102: The external terminal equipment analyzes and processes the lithium battery data, fits the charging and discharging curve or calculates the lithium battery capacity;

[0065] That is, the abstract lithium battery data parameters are transformed into more vivid image data for display.

[0066] 103: The user can judge the health of the lithium battery through the external terminal equipment.

[0067] see Figure 6 , during specific implementation, in the lithium battery information column interface of the smart phone (external terminal device), you can clearly see the relevant graphic data, includi...

Embodiment 3

[0074] A kind of control method of intelligent lithium battery protection device, see Figure 5 and Figure 10 , the control method includes the following steps:

[0075] 201: The external terminal device obtains the lithium battery data collected by the intelligent lithium battery protection device through bluetooth technology, wifi technology, or infrared technology;

[0076] 202: The external terminal device uploads the lithium battery data to the cloud space through cloud technology;

[0077] 203: The background personnel analyze the lithium battery data in the cloud space and give the analysis results.

[0078] Among them, the analysis results include: suggestions on the use of lithium batteries, as well as detailed usage reports, and inform the user whether the current lithium battery status needs to be replaced. If it needs to be replaced, the background staff will notify the user to the nearest agent to replace the lithium battery.

[0079] To sum up, in the embodim...

Abstract

The invention discloses an intelligent lithium battery protection device and a control method thereof. A battery core is detected by the lithium battery protection device; the detection result is stored in the lithium battery protection device; in free time, all detection data in the lithium battery protection device are uploaded to a mobile phone terminal by a mobile phone with a bluetooth or wifi; the mobile phone terminal can analyze data with application (APP) software, so that the current health state, the discharge curve and various fault messages of the lithium battery in the using process can be clearly seen. If a user wants to change the lithium battery, the current battery information can be uploaded to a cloud space; and a manufacturer can contact the nearest agent to change the lithium battery according to the data in the cloud space, so that the possibility of risks such as fires and explosion due to the fact that the battery is misused by the user is lowered; and the safety use level of an overall vehicle is greatly improved.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to an intelligent lithium battery protection device and a control method thereof. Background technique [0002] The development of lithium batteries has a history of more than ten years. With the continuous improvement of lithium battery technology and the country's encouragement for the development of new energy, lithium batteries have become more and more widely used, such as: mobile phone batteries, charging treasures, electric bicycles, Electric cars, electric buses, medical equipment or various digital products, etc. [0003] The various applications of lithium batteries bring convenient services to people's lives, but also highlight the safety of lithium batteries. Explosions, spontaneous combustion, and other accidents of lithium batteries during use are becoming more and more frequent. Therefore, the protection management and detection of lithium batteries are particularly...
