Through the additionally arranged heating device of the battery pack, the battery pack disclosed by the invention is enabled to be applicable to a low temperature environment.
Description
Technical field
The present invention relates to a kind of battery bag, more particularly to a kind of battery bag that can be used in low temperature environment.
Background technology
Portable electron device has been the indispensable indispensable instrument of many people life at present, therefore how to make portable electric
Son is provided and can keep running all the time, has been one of emphasis of portable electron device mesh development.Battery bag
The electric power provided by (battery pack), is that portable electron device realizes portability and in order to keep the important pass for operating
Key, therefore the length of battery bag power-on time, easily affects the operational effectiveness of portable electron device.
Using the portable electron device in the environment of low temperature, the power-on time provided by battery bag, almost room temperature
/ 3rd of environment (about 25 DEG C) are even lower.This is because the electrolyte of battery is when temperature reduces, its viscosity increases,
Ion motion is subject to larger resistance, and diffusivity reduces makes the activity of battery reduce and cause battery capacity to decline；Next low temperature
Also result in negative electrode active material utilization rate decline thus impact battery charge capacity.Research finds, the discharge temp scope of battery
Generally -20 DEG C to 70 DEG C, when ambient temperature is less than charge and discharge electro-temperature allowable, battery may discharge and recharge or discharge and recharge
Performance extreme difference, impact is used.
Therefore under the environmental condition of low temperature, how to make battery bag that normal electricity is stilld provide, become research worker and wait to solve
Certainly one of problem.
Content of the invention
In order to overcome drawbacks described above, the invention provides a kind of battery bag that can be useful in low temperature environment.
The technical solution adopted for the present invention to solve the technical problems is：A kind of battery bag, the battery bag include battery and
Heater, the heater detects the temperature of the battery bag comprising thermal source, thermal insulation layer and temperature sensor, the temperature sensor
When degree is less than a specified temp, heater is heated to the battery bag.
Further, the thermal insulation layer is arranged on the outside of the thermal source, plays insulation effect.
Further, the battery bag is additionally provided with switch, and the on-off control temperature sensor carries out thermometric.
Further, when temperature sensor detects the battery bag temperature less than the specified temp, battery bag will be provided
Weak current slowly preheats the battery bag, i.e. thermal source and starts working.
Further, the thermal source is gradually increasing battery bag temperature, reaches when temperature sensor detects battery bag temperature
During one predetermined temperature, thermal source stops heating.
Further, above-mentioned specified temp is subzero 20 DEG C.
Further, the switch is arranged on the outside of the battery bag, convenient operation.
Present invention also offers another technical scheme is：A kind of D.C. electric drill, the D.C. electric drill includes above-mentioned battery bag.
Present invention also offers another technical scheme is：A kind of D.C. electric drill, the D.C. electric drill includes above-mentioned battery bag.
Present invention also offers another technical scheme is：A kind of direct current spanner, the direct current spanner includes above-mentioned battery bag.
The heater that battery bag of the present invention is set up enables battery bag of the present invention to be applied to low temperature environment.
Description of the drawings
The above and other feature of the present invention, property and advantage are by by description with reference to the accompanying drawings and examples
And become apparent, identical reference represents identical feature all the time in the accompanying drawings, wherein：
Fig. 1 is the partial cutaway schematic of battery bag of the present invention.
Fig. 2 is another partial cutaway schematic of battery bag of the present invention.
Drawing label declaration：
Thermal source 1；Thermal insulation layer 2；Switch 3；Temperature sensor 4
Specific embodiment
Now with detailed reference to Description of Drawings embodiments of the invention.Present being preferable to carry out with detailed reference to the present invention
Example, its example is shown in the drawings.In the case of any possible, phase will be represented using identical labelling in all of the figs
Same or similar part.Additionally, the term although used in the present invention is selected from public term, but this
Some terms mentioned in description of the invention are probably that applicant carrys out selection by his or her judgement, and its detailed meanings is at this
Explanation in the relevant portion of the description of text.In addition, it is desirable to not only by the actual terms for being used, and be also to by each
The meaning contained by term is understanding the present invention.
As shown in Figure 1 and Figure 2, the present invention relates to a kind of battery bag, DC tools can apply to, such as D.C. electric drill, straight
Stream spanner etc..The battery bag includes battery and heater, and when the temperature is too low, heater is used for improving the temperature of the battery bag
Degree.
The heater is comprising thermal source 1, thermal insulation layer 2, switch 3 and temperature sensor 4.Thermal source 1 recline battery setting, heat-insulated
Layer is arranged on the outside of thermal source, plays insulation effect.Switch is arranged on the outside of battery bag, convenient operation.Temperature sensor 4 is used for
Detection battery temperature, is NTC temperature sensor.
The battery can be nickel-cadmium cell, Ni-MH battery, lithium battery etc..
When battery bag of the present invention is used under the too low environment of temperature, switch is pressed, temperature sensing 4 is started working, detection
Battery temperature, generally -20 DEG C to 70 DEG C of battery discharge and recharge temperature range allowable, when the temperature that NTC temperature sensor is detected
During charge and discharge electro-temperature allowable less than the battery, battery bag will provide weak current and slowly preheat the battery bag, the i.e. beginning of thermal source 1 work
Make；Battery temperature is gradually increasing, and when temperature sensor 4 detects battery and reaches uniform temperature, control thermal source 1 stops heating, this
When battery bag can be normally carried out discharge and recharge.
Battery bag of the present invention increased thermal source, and during use, battery bag itself produces heat, and thermal insulation layer plays insulation effect,
Reduce heat diffusion speed, so that battery bag temperature is maintained in the preferred range, low temperature can be significantly improved by above scheme
