Ion battery.Lithium ion battery does not contain the lithium of metallic state, and can charge.
Lithium battery is influenced by temperature larger during charge and discharge, and high temperature and low temperature can be to the charge and discharge of lithium battery
Time and shelf-life impact, or even cause the irreversible damage of lithium battery, it is therefore desirable to the temperature of lithium battery into
Row is monitored and is protected, and lacks in the prior art and lithium battery is effectively protected, and can not be carried out to the temperature of lithium battery real-time
Monitoring and to temperature realize quickly in real time adjust, to reduce and eliminate influence of the temperature to lithium battery.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of Intelligent lithium battery protection proposed
Method.
To achieve the goals above, present invention employs following technical solutions:
A kind of Intelligent lithium battery guard method, the described method comprises the following steps:
S1. mounting temperature sensor is attached in the lateral wall of lithium battery, which is connect with controller, controlled
Device is connected with radiator and heating device simultaneously；
S2. when lithium battery works, temperature sensor carries out temperature detection, and the temperature data that will test to lithium battery in real time
It is transferred to controller, controller analyzes temperature data, and controller can send a command to radiator and heating dress respectively
It sets；
S3. radiator and heating device are run according to the instruction of controller, and radiator radiates to lithium battery, adds
Thermal carries out heat temperature raising to lithium battery.
Preferably, in the S2, controller is built-in with first threshold and second threshold；
S21. if the temperature data of temperature sensor detection is greater than first threshold, controller sends first to radiator
Instruction, the first instruction control radiator operation, when temperature data is reduced between first threshold and second threshold, controller
Third instruction is sent to radiator, third instruction control radiator is out of service；
S22. if the temperature data of temperature sensor detection is less than second threshold, controller sends second to heating device
Instruction, the second instruction control heating device operation, when temperature data rises between first threshold and second threshold, controller
The 4th instruction, the 4th instruction control heater stop operation are sent to heating device.
Preferably, the radiator and heating device are arranged at the outside of lithium battery, and keep certain with lithium battery
Distance.
Compared with the prior art, the beneficial effects of the present invention are:
The guard method of this programme can realize real-time temperature detection to lithium battery and calculate temperature averages, by temperature
Average value is compared with the threshold value of controller, is then controlled by controller heating device and radiator, in turn
It realizes and adjusting in real time is realized to the temperature of lithium battery, can greatly eliminate influence of the temperature to lithium battery, promote lithium battery normal
It uses.
Specific embodiment
A kind of Intelligent lithium battery guard method, the described method comprises the following steps:
S1. attached in the lateral wall of lithium battery and multiple temperature sensors be installed, by multiple temperature sensors simultaneously with control
Device connection, controller are connected with radiator and heating device simultaneously；
S2. when lithium battery works, each temperature sensor carries out temperature detection, and the temperature that will test to lithium battery in real time
Degree is according to controller is transferred to, and temperature averages are analyzed relatively temperature data and be calculated to controller, and controller can
Radiator and heating device are sent a command to respectively；
S3. radiator and heating device are run according to the instruction of controller, and radiator radiates to lithium battery, adds
Thermal carries out heat temperature raising to lithium battery.
In the S2, controller is built-in with first threshold and second threshold；
S21. if temperature averages are greater than first threshold, controller sends the first instruction, the first instruction to radiator
Radiator operation is controlled, when temperature averages are reduced between first threshold and second threshold, controller is to radiator
Third instruction is sent, third instruction control radiator is out of service；
S22. if temperature averages are less than second threshold, controller sends the second instruction, the second instruction to heating device
Heating device operation is controlled, when temperature averages rise between first threshold and second threshold, controller is to heating device
Send the 4th instruction, the 4th instruction control heater stop operation.
The radiator and heating device are arranged at the outside of lithium battery, and maintain a certain distance with lithium battery.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
