Description
Technical field
The utility model relates to a kind of power battery box for electric motor car.
Background technology
Electric motor car is deep into each sphere of life of people gradually.At present, Electric Transit, electric sanitation truck and electric taxi etc. are widely adopted.
For electric motor car, the especially electric motor car of replaceable power battery box, power battery box are one of crucial parts.
Present power battery box mainly comprises housing and is positioned in battery cell in the housing, by certain cascaded structure these battery bodies is connected together, thereby provides certain voltage and capacity power source for electric motor car.
Along with being widely used of electric motor car, the environment for use of power battery box also becomes increasingly complex, especially the environment such as some high temperature and low temperature.
The utility model content
The purpose of this utility model is to provide a kind of power battery box that can be advantageously applied to the complex environments such as high temperature and low temperature.
A kind of power battery box of the present utility model comprises: casing and the battery cell that is positioned in the casing, be provided with semiconductor chilling plate at casing, this semiconductor chilling plate has the first temperature control end face that is positioned at described casing and is positioned at the second outer temperature control end face of described casing.
Preferably, be provided with the first heat exchange unit at described the first temperature control end face, be provided with the second heat exchange unit at described the second temperature control end face.
Preferably, offer installing hole at the sidewall of described casing, described semiconductor chilling plate is installed on the described installing hole, and forms hermetically-sealed construction with described casing.
Preferably, described the first heat exchange unit is the radiating block with radiating fin.
Preferably, described the first heat exchange unit comprises that described metal framework links to each other with described radiating block be used to the metal framework that described battery cell is installed and the radiating block that is arranged on described the first temperature control end face.
Preferably, described the second heat exchange unit is air-cooled or water-filled radiator.
The semiconductor chilling plate of the utility model by the casing setting is had the temperature control action controlled temperature in the Battery case by this semiconductor chilling plate.In the time the battery cell temperature in the casing need to being lowered, it is the low temperature face that semiconductor chilling plate makes the first temperature control end face, and the second temperature control end face then is high temperature face, thereby the temperature exchange in the casing is outside to casing.And when need to be with the temperature increase of the battery cell in the casing, it be high temperature face that semiconductor chilling plate makes the first temperature control end face, and the second temperature control end face then is the low temperature face, thereby battery cell temperature in the casing is risen to predetermined temperature.Like this, no matter hot environment or low temperature environment can both be realized the temperature of the battery cell in the casing is controlled at predetermined temperature, thereby be convenient to the use of power battery box.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the A-A of Fig. 1 is to cross-section structure part schematic diagram;
Fig. 3 is the structural representation of another embodiment of the present utility model.
Embodiment
Below, with reference to description of drawings a kind of execution mode of the present utility model.
As shown in Figure 1, 2, the utility model comprises casing 1 and is positioned in battery cell 2 in the casing 1, in addition, on casing 1, also be provided with not shown go out be used for electricity output or the pole of charging etc.Sidewall at casing 1 offers installing hole, is provided with semiconductor chilling plate 3 in installing hole, and this semiconductor chilling plate 3 has the first temperature control end face 31 and the second temperature control end face 32 that is positioned at outside the casing 1 that is positioned at casing 1.When having electric current to pass through semiconductor chilling plate, will at one end generate heat, other end cooling, thereby produce the temperature difference.Like this, when needs are lowered the temperature in to casing 1, make 31 coolings of the first temperature control end face, 32 heatings of the second temperature control end face, the heat that is about in the casing 1 exchanges by semiconductor chilling plate 3.And when needs heat, make 31 heatings of the first temperature control end face, and make 32 coolings of the second temperature control end face, the heat of casing 1 outside can be exchanged to casing 1 inside by semiconductor chilling plate 3, thereby realize heating.
In addition, for the ease of the control of temperature, semiconductor chilling plate 3 forms hermetically-sealed construction with casing 1.
Like this, the structure that just casing 1 can be designed to roughly seal, thus the temperature in the casing 1 is controlled in realization, namely controls the temperature of battery cell 2, is convenient to power battery box and is used for different environment, such as the hot environments of 40 degree or the low temperature environment of minus 20 degrees.
In addition, in order controlling the temperature of casing 1 better, to be provided with the first heat exchange unit 4 at the first temperature control end face 31, to be provided with the second heat exchange unit 5 at the second temperature control end face 32.
The first heat exchange unit 4 for example can for having the radiating block of radiating fin, carry out heat exchange so that realize heat and the first temperature control end face 31 in the casing 1.
Certainly, the first heat exchange unit 4 can be structure as shown in Figure 3, comprises that metal framework 6 links to each other with radiating block for the metal framework 6 that battery cell 2 is installed and the radiating block that is arranged on the first temperature control end face 31.Like this, can directly battery cell 2 be lowered the temperature or heat up, thereby control better the temperature of battery cell 2.
In addition, the second heat exchange unit 32 can be air-cooled radiator, also can be water-filled radiator, so that the temperature exchange of the second temperature control end face 32 is gone out.
The semiconductor chilling plate 3 of the utility model by casing 1 setting is had the temperature control action controlled temperature in the Battery case 1 by this semiconductor chilling plate 3, thus the temperature of control battery cell 2.
In the time battery cell 2 temperature in the casing 1 need to being lowered, semiconductor chilling plate 3 makes the first temperature control end face 31 be the low temperature face, and the second temperature control end face 32 then be high temperature face, thereby the temperature exchange that casing 1 is interior is to casing 1 outside.
And when need to be with the temperature increase of the battery cell 2 in the casing 1, semiconductor chilling plate 3 makes the first temperature control end face 31 be high temperature face, and the second temperature control end face 32 then is the low temperature face, thereby casing 1 interior battery cell 2 temperature are risen to predetermined temperature.
Like this, no matter hot environment or low temperature environment can both be realized the temperature of the battery cell 2 in the casing 1 is controlled at predetermined temperature, thereby be convenient to the use of power battery box.
Although the above is illustrated embodiment of the present utility model, these execution modes are to point out as an example, and do not attempt to limit the scope of utility model.These new execution modes can be implemented with other variety of ways, in the scope of the purport that does not break away from utility model, can carry out various omissions, displacement and change.These execution modes or its distortion are contained in the scope and purport of utility model, and are contained in utility model that the scope of patent request puts down in writing and the scope impartial with it.
