Abstract
The invention discloses a method for testing a wind field of a heat management system in a battery pack, which comprises the following steps of: sleeving a transparent sealed box body outside the battery pack and a fan, then filing smoke into the transparent sealed box body from a smoke inlet of the transparent sealed box body, and blowing the smoke into the battery pack by the fan in the transparent sealed box body; and observing an outlet position, at which the smoke inside the transparent sealed box body is dispersed outwards from the inside of the battery pack, from the outside of the transparent sealed box body, wherein when the outlet position of the smoke is only positioned at an air outlet, the design of the wind field of the heat management system in the battery pack is reasonable, and when the smoke is dispersed from the tightly packaged side wall of the battery pack, the design of the wind field of the heat management system has defects and the wind field of the heat management system has poor sealing performance. The method has a simple test structure. In the test method, people can observe by naked eyes, so that the test method is visual and convenient.
Description
Technical field
The present invention relates to batteries of electric automobile group field, specifically a kind of method of testing of wind field of heat management system in battery pack.
Background technology
Existing batteries of electric automobile group is comprised of a plurality of monocell tandem stacks, monocell after tandem stack in use can produce heat, so air inlet and air outlet are set on electric battery, and at the sidepiece that is provided with air inlet, fan is set, guaranteed that wind enters air outlet process out from air inlet, wind energy is blown over each monocell, facilitates the dispersion of the heat of the generation of monocell in electric battery.But when the sidewall sealing that is not provided with ventilating opening is incomplete, the sidewall that the wind that fan is blown into never seals disperses out, relative wind just can not be blown over each monocell fully, the relative thermal diffusivity that has just reduced monocell in electric battery, the serviceable life of having reduced whole electric battery.After the current battery group was produced, in electric battery, whether rational problem did not also have corresponding method to detect to heat dissipation wind channel, and this has brought difficulty with regard to the evaluation and test of giving the electric battery thermal diffusivity.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of testing of wind field of heat management system in battery pack, solves existing wind field of heat management system in battery pack and detects the rationality hard problem.
Technical scheme of the present invention is:
A kind of method of testing of wind field of heat management system in battery pack is provided with air inlet and air outlet on described electric battery, the sidepiece that electric battery is positioned at air inlet outward is provided with fan, and the method for testing of wind field of heat management system in battery pack specifically comprises the following steps:
At the outside of electric battery and fan suit transparent sealing casing, then fill with smog from the mouth that advances of transparent sealing casing to the transparent sealing box house, the fan in the transparent sealing casing is blown into smog in electric battery;
The exit position that disperses outward in from transparent sealing case observation in vitro transparent sealing box house smog from electric battery, judge whether problem reasonable in design of heat management system wind field in electric battery: when the exit position of smog only is air outlet, illustrate that the interior heat management system wind field of electric battery is reasonable in design; When smog disperses out from the tight sidewall of battery unit package, illustrate that the heat management system wind field is designed with defective, the closure of its wind field is bad.
Describedly advance mouth and be arranged on the transparent sealing casing sidewall relative with air inlet or air outlet.
Described to advance mouth be 1, is arranged on the transparent sealing casing sidewall relative with air inlet.
Advantage of the present invention:
(1), the present invention arranges the transparent sealing casing outside electric battery, convenient situation of observing in the transparent sealing casing, and leakproofness is arranged very much because it has is blown into that in the transparent sealing casing, smog is difficult to disperse away from the transparent sealing casing;
(2), adopt smog to enter the position of the input and output of wind field in electric battery, whether judgement does not seal intact position, its detection method intuitive and convenient on electric battery in addition except air outlet and air inlet position.
Description of drawings
Fig. 1 detection architecture schematic diagram of the present invention.
Embodiment
See Fig. 1, be provided with air inlet 2 and air outlet 3 on electric battery 1, the outer sidepiece that is positioned at air inlet 2 of electric battery 1 is provided with fan 4, and in electric battery, the method for testing of heat management system wind field specifically comprises the following steps:
At the outside of electric battery 1 and fan 4 suit transparent sealing casing 5, be provided with one on transparent sealing casing 5 sidewall relative with air inlet 2 and advance mouth 6, then from transparent sealing casing 5 advance mouth 6 to the inner smog of filling with of transparent sealing casing 5, the fans in transparent sealing casing 5 are blown into smog in electric battery 1;
The exit position that disperses outward in from the outer observation transparent sealing of transparent sealing casing 5 casing 5 internal aerosol from electric battery 1, judge whether problem reasonable in design of wind field of heat management system in battery pack: when the exit position of smog only is air outlet 3, illustrate that wind field of heat management system in battery pack is reasonable in design; When smog disperses out from the tight sidewall of battery unit package, illustrate that the heat management system wind field is designed with defective, the closure of its wind field is bad.
Claims (3)
1. the method for testing of a wind field of heat management system in battery pack, be provided with air inlet and air outlet on described electric battery, the sidepiece that electric battery is positioned at air inlet outward is provided with fan, it is characterized in that: the method for testing of wind field of heat management system in battery pack specifically comprises the following steps:
At the outside of electric battery and fan suit transparent sealing casing, then fill with smog from the mouth that advances of transparent sealing casing to the transparent sealing box house, the fan in the transparent sealing casing is blown into smog in electric battery;
The exit position that disperses outward in from transparent sealing case observation in vitro transparent sealing box house smog from electric battery, judge whether problem reasonable in design of wind field of heat management system in battery pack: when the exit position of smog only is air outlet, illustrate that wind field of heat management system in battery pack is reasonable in design; When smog disperses out from the tight sidewall of battery unit package, illustrate that the heat management system wind field is designed with defective, the closure of its wind field is bad.
2. the method for testing of a kind of wind field of heat management system in battery pack according to claim 1 is characterized in that: describedly advance mouth and be arranged on the transparent sealing casing sidewall relative with air inlet or air outlet.
3. the method for testing of a kind of wind field of heat management system in battery pack according to claim 2 is characterized in that: described to advance mouth be 1, is arranged on the transparent sealing casing sidewall relative with air inlet.
