Abstract
The invention relates to a method of controlling the heat transfer speed of a battery in a sealed box body. The method comprises the steps of detecting the external environment temperature t1 of the sealed box body provided with the battery and the internal environment temperature t2 of the sealed box body provided with the battery; controlling the heat transfer speed of the box body by controlling the air amount in the sealed box body; reducing the air pressure in the box body by a vacuum pump; recovering the air amount in the sealed box body by a vent valve. The method of controlling the heat transfer speed of the battery in the sealed box body has the beneficial effects that the heat transfer speed is controlled by means of the air pressure on the box body, so that the head transfer speed in the box body is continuously controlled in a certain range, and the control is simple.
Description
Technical field
The present invention relates to a kind of method of controlling the heat transfer speed of battery in airtight casing.
Background technology
Conventionally producer is by keep the temperature of battery core not change with extraneous variation with thermal insulation material.And with the temperature variation of crossing thermal insulation material assurance battery core, really can slow down the temperature changing speed of battery core, but this method is fixed the heat transfer speed restriction of battery, uncontrollable, and the method that the present invention tells about, the heat of battery is passed to the adjusting that ground speed can be real-time, make battery heat transfer speed to external world always in a more satisfactory state.
Summary of the invention
The object of this invention is to provide a kind of method of controlling the heat transfer speed of battery in airtight casing, to overcome currently available technology above shortcomings.
The object of the invention is to be achieved through the following technical solutions:
A method of controlling the heat transfer speed of battery in airtight casing, comprises the following steps:
1) detect the closed box external body environment temperature t1 that is placed with battery and the airtight casing interior environment temperature t2 that is placed with battery;
2) the interior environment temperature t2 detecting when step 1) is battery operated standard temperature T, while being t2=T, the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2 or ambient temperature t1 and is less than interior environment temperature t2, by vacuum pump, extract air in airtight casing and reduce airtight casing internal gas pressure;
When the interior environment temperature t2 of step 1) detection is greater than battery operated standard temperature T, the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2, by vacuum pump, extract air in airtight casing and reduce airtight casing internal gas pressure, when ambient temperature t1 is less than interior environment temperature t2, by vent valve, recover the air capacity in airtight casing;
When the interior environment temperature t2 of step 1) detection is less than battery operated standard temperature T, the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2, by vent valve, recover the air capacity in airtight casing, when ambient temperature t1 is less than interior environment temperature t2, by vacuum pump, extracts air in airtight casing and reduce airtight casing internal gas pressure.
When the closed box external body environment temperature t1 of step 1) detection equates with airtight casing interior environment temperature t2, be left intact.
Beneficial effect of the present invention is: owing to adopting casing internal gas pressure to control heat transfer speed, thus the heat transfer speed within the specific limits in continuous control casing, and control simple.
Accompanying drawing explanation
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the process flow diagram of the method for the heat transfer speed of battery in the airtight casing of the control described in the embodiment of the present invention.
Embodiment
As shown in Figure 1, a kind of method of controlling the heat transfer speed of battery in airtight casing described in the embodiment of the present invention, is characterized in that, comprises the following steps:
1) detect the closed box external body environment temperature t1 that is placed with battery and the airtight casing interior environment temperature t2 that is placed with battery;
2) the interior environment temperature t2 detecting when step 1) is battery operated standard temperature T, while being t2=T, the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2 or ambient temperature t1 and is less than interior environment temperature t2, by vacuum pump, extract air in airtight casing and reduce airtight casing internal gas pressure;
During the battery operated standard temperature T of the interior environment temperature t2> that detects when step 1), the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2, by vacuum pump, extract air in airtight casing and reduce airtight casing internal gas pressure, when ambient temperature t1 is less than interior environment temperature t2, by vent valve, recover the air capacity in airtight casing;
During the battery operated standard temperature T of the interior environment temperature t2< that detects when step 1), the size of judgement ambient temperature t1 and interior environment temperature t2, when ambient temperature t1 is greater than interior environment temperature t2, by vent valve, recover the air capacity in airtight casing, when ambient temperature t1 is less than interior environment temperature t2, by vacuum pump, extracts air in airtight casing and reduce airtight casing internal gas pressure.
When the closed box external body environment temperature t1 of step 1) detection equates with airtight casing interior environment temperature t2, be left intact.
Thereby the present invention changes the method for controlling of heat transfer speed in airtight casing by changing air pressure in airtight casing, by controlling gas flow in airtight casing, control the heat transfer speed of casing, airtight casing can be any airtight casing, by vacuum pump, reduce the air pressure in casing, by air release, recover the air pressure in casing.
There is certain relation in transmission speed and the air capacity in casing of heat, when ambient temperature is not suitable for battery operated temperature, can be by reducing the air in battery case, thus slow down heat transmission, extend the time that battery is worked at the temperature adapting to.For example, when casing ambient temperature is spent lower than subzero 10, by transferring the air in casing, make battery in casing within the longer time, keep current than better suited temperature.Or when casing ambient temperature is spent higher than 40, same by transferring the air in casing, make battery in casing within the longer time, keep current than better suited temperature.Can carry out detected temperatures value by temperature sensor, if ambient temperature higher than 30, and in casing, the temperature of power brick, lower than 30 degree, needs to take out air in bag, if ambient temperature is 25 degree, and the temperature inside the box is higher than 35 degree, recovers air in case.
The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
