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 is a kind of method of testing of electric battery heat management system wind field.
Background technology
The traditional electric automobile electric battery is made up of a plurality of monocell tandem stacks; Monocell behind the tandem stack in use can produce heat; So air inlet and air outlet are set on the electric battery, and fan are set, guaranteed that wind is from the process that air inlet entering air outlet comes out at the sidepiece that is provided with air inlet; Wind energy is blown over each monocell, makes things convenient for the dispersion of the heat of the generation of monocell in the electric battery.But when the sidewall that is not provided with ventilating opening seals when 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 the electric battery, the serviceable life of having reduced whole battery group.After the current battery group was produced, whether rational problem did not also have corresponding method to detect to heat dissipation wind channel in the electric battery, 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 matters that the present invention will solve provides a kind of method of testing of electric battery heat management system wind field, solves the problem that existing electric battery heat management system wind field detects the rationality difficulty.
Technical scheme of the present invention is:
A kind of method of testing of electric battery heat management system wind field, described electric battery is provided with air inlet and air outlet, and the sidepiece that electric battery is positioned at air inlet outward is provided with fan, and the method for testing of electric battery heat management system wind field specifically may further comprise the steps:
At the outside suit transparent sealing casing of electric battery and fan, irritate smog from the mouth that advances of transparent sealing casing to the transparent sealing box house then, the fan in the transparent sealing casing is blown into smog in the electric battery;
Outside the transparent sealing casing, observe the exit position that transparent sealing box house smog disperses in the electric battery outward; Judge the problem that heat management system wind field in the electric battery is whether reasonable in design:, explain that the interior heat management system wind field of electric battery is reasonable in design when the exit position of smog is merely air outlet; When smog when the tight sidewall of pack disperses out, explain 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 relative sidewall of transparent sealing casing and air inlet or air outlet.
Described to advance mouth be 1, is preferably disposed on the relative sidewall of transparent sealing casing and air inlet.
Advantage of the present invention:
(1), the present invention is provided with the transparent sealing casing outside electric battery, convenient situation of observing in the transparent sealing casing, and because it has leakproofness is arranged very much, be blown into that smog is difficult to from the transparent sealing casing, disperse away in the transparent sealing casing;
(2), adopt smog to get into the position of the input and output of wind field in the electric battery, judge except that air outlet and air inlet position, whether do not seal intact position in addition, its detection method intuitive and convenient on the electric battery.

Embodiment
See Fig. 1, electric battery 1 is provided with air inlet 2 and air outlet 3, and the electric battery 1 outer sidepiece that is positioned at air inlet 2 is provided with fan 4, and the method for testing of heat management system wind field specifically may further comprise the steps in the electric battery:
Outside suit transparent sealing casing 5 at electric battery 1 and fan 4; Transparent sealing casing 5 is provided with one with air inlet 2 relative sidewalls and advances mouth 6; Irritate smog from the mouth 6 that advances of transparent sealing casing 5 to transparent sealing casing 5 inside then, the fans in the transparent sealing casing 5 are blown into smog in the electric battery 1;
Outside transparent sealing casing 5, observe the exit position that transparent sealing casing 5 internal aerosol are disperseed in the electric battery 1 outward; Judge the problem that electric battery heat management system wind field is whether reasonable in design:, explain that electric battery heat management system wind field is reasonable in design when the exit position of smog is merely air outlet 3; When smog when the tight sidewall of pack disperses out, explain 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 an electric battery heat management system wind field; Described electric battery is provided with air inlet and air outlet; 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 electric battery heat management system wind field specifically may further comprise the steps:
At the outside suit transparent sealing casing of electric battery and fan, irritate smog from the mouth that advances of transparent sealing casing to the transparent sealing box house then, the fan in the transparent sealing casing is blown into smog in the electric battery;
Outside the transparent sealing casing, observe the exit position that transparent sealing box house smog disperses in the electric battery outward; Judge the problem that electric battery heat management system wind field is whether reasonable in design:, explain that electric battery heat management system wind field is reasonable in design when the exit position of smog is merely air outlet; When smog when the tight sidewall of pack disperses out, explain 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 electric battery heat management system wind field according to claim 1 is characterized in that: describedly advance mouth and be arranged on the relative sidewall of transparent sealing casing and air inlet or air outlet.
3. the method for testing of a kind of electric battery heat management system wind field according to claim 2 is characterized in that: described to advance mouth be 1, is preferably disposed on the relative sidewall of transparent sealing casing and air inlet.
