Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, with
Lower embodiment combination attached drawing improves battery system of performance in low temperature to the utility model and is specifically addressed.
The system 100 for improving battery performance in low temperature is mainly used in off working state and enters suspend mode, and when work is automatic
The equipment of wake-up.As shown in Figure 3, Figure 4, the system 100 for improving battery performance in low temperature includes: battery 10, temperature detection list
Member 20, voltage detection unit 30, heating unit 40 and control unit 50.
Battery 10 is used to provide electric energy for equipment.
Temperature detecting unit 20 is mounted near battery, is connect with battery 10, provides electric energy, temperature inspection by battery 10 for it
Survey the temperature that unit 20 is used to detect 10 ambient enviroment of battery.In the present embodiment, temperature detecting unit 20 is temperature sensor.
Heating unit 40 is mounted near battery 10, is connect with battery 10, provides electric energy, heating unit by battery 10 for it
40 for heating the temperature of 10 ambient enviroment of battery.In the present embodiment, heating unit 40 is electric heating wire, and heater strip can divide
Surrounding of the cloth in battery.
In the present embodiment, battery 10 is wrapped up by a shell, and temperature detecting unit 20 and heating unit 40 are arranged at outside
In shell, heating unit 40 is facilitated to heat the temperature of battery ambient environment.
Voltage detection unit 30 is connected in parallel with battery 10, for detecting the voltage of battery 10.In the present embodiment, voltage
Detection unit 30 is voltmeter.
Control unit 50 is connect with temperature detecting unit 20, voltage detection unit 30, heating unit 40.In the present embodiment
In, as shown in figure 4, connecting after 40 parallel connection of temperature detecting unit 20 and heating unit with control unit 50, control unit 50 is connected
Battery 10.Control unit 50 is connect with the component for capableing of wake-up device, receives calling out for the component transmission for capableing of wake-up device
Awake signal, wake-up signal can be wireless signal, be also possible to the signal of wire transmission.
Control unit 50 is stored with the voltage-capacity discharge characteristic curve of battery at different temperatures.In the present embodiment,
Control unit 50 is the single-chip microcontroller with store function, i.e., the chip of EEPROM or FLASH, example inside single-chip microcontroller band
Such as: STC89C51, STC12C5612 and AVR single chip of STC.
As shown in figure 5, the control flow of control unit 50 are as follows: when equipment needs to wake up, control unit 50 will receive wake-up
Signal, starts the state for detecting battery, and control unit 50 reads 10 ambient enviroment of battery that temperature detecting unit 20 detects at this time
Temperature, voltage detection unit 30 detect battery 10 voltage, put then in conjunction with the voltage-capacity of battery at different temperatures
Whether battery can satisfy the demand of normal work to the judgement of electrical characteristics curve at this time, if being able to satisfy demand, control unit 50 is controlled
Control equipment enters normal work program；If control unit 50 controls heating unit 40 and opens, to electricity it is impossible to meet demand
Pond ambient enviroment is heated, and is heated to scheduled temperature, the battery 10 that control unit 50 is detected in temperature detecting unit 20
After the temperature of ambient enviroment is more than or equal to predetermined temperature, control heating unit 40 stops heating, and then control equipment enters normal
Working procedure.In the present embodiment, predetermined temperature refers to 25 degrees Celsius of room temperature, since performance is good at normal temperature for battery.
For example, certain uses the locating reporting system of lithium battery power supply, locating reporting system includes GSM/3G/LTE receive-transmit system
And GPS positioning system.The locating reporting system needs to report a latitude and longitude information daily, and the working time is no more than 5 minutes, work
Electricity consumption is more when work, and in a dormant state, power consumption is extremely low for remaining time device.
After reaching the time of equipment wake-up work, control unit 50 receives wake-up signal, and control unit 50 is according to reality
When battery voltage and environment temperature judge whether present battery status can satisfy the requirement of this task, if it is possible to it is full
Foot, then locating reporting system starts to work normally；If it is impossible to meet control unit 50 controls heating unit 40 to battery week
Collarette border is heated, and is heated to room temperature or more, and reaching room temperature according to the temperature that temperature detecting unit 20 detects, (25 is Celsius
Degree), control unit 50 controls heating unit 40 and stops heating, and then locating reporting system starts to work normally.When work terminates
Afterwards, locating reporting system enters dormant state, waits wake up next time.
Battery ambient environment is heated, so that battery 10 is under higher environment temperature, so as to improve electricity
The capacity in pond 10, so that battery 10 can satisfy equipment normal work.Certainly, made by heating the environment temperature of battery ambient
Battery can work normally, and can only be sufficient in battery 10 electricity itself, and be only because of battery caused by environment temperature is too low
It is feasible with ability when off-capacity, if battery not enough power supply itself is worked normally with holding equipment, using heating battery ambient temperature
The mode of degree is simultaneously not suitable for.
Enter dormant state when the utility model is primarily directed to inoperative, the equipment that when work automatically wakes up works as needs
When wake-up device, wake-up signal is issued to control unit 50, control unit 50 receives wake-up signal, starts the shape for detecting battery
State.The equipment that may naturally be used for not needing suspend mode, such as in the weather of severe cold, battery can not normal work because weather is cold
When making, the component for capableing of wake-up device that control unit 50 connects at this time is peripheral control unit, is mentioned by peripheral control unit control
The work of the system 100 of high battery performance in low temperature.
Above embodiment is the preferred case of the utility model, is not intended to limit the protection scope of the utility model.
