Abstract
The invention discloses an auxiliary heating apparatus for a battery box. The auxiliary heating apparatus comprises a battery box body, a ceramic PTC heating plate and two heat conducting panels, wherein the two heat conducting panels are symmetrically fixed on the two sides of the battery box body; the ceramic PTC heating plate is fixed on one sides, far from the battery box body, of the heat conducting panels; and an electric connector is arranged at one end of the ceramic PTC heating plate. According to the auxiliary heating apparatus for the battery box, the auxiliary heating is realized by adopting the heating plate with a ceramic positive temperature coefficient; when the temperature of the heating plate achieves the threshold value in the heating process, the resistance value of the PTC is increased sharply; as a result, the heating power is reduced suddenly to realize controllable temperature; therefore, the problem that the temperature of the heating plate cannot be controlled is solved; the heat conducting panels with a higher heat conducting coefficient are adhered to the battery box body, so that a more uniform heat conducting temperature field can be realized; overhigh partial temperature can be avoided; the monitoring of the battery management system can be carried out conveniently; and the safety of the battery can be ensured.

Being protruded with two strip projections, in hollow form inside described projection, described ceramic PTC heating plate plugs
In the inside of described projection, described electric connection is exposed to outside.
As a further improvement on the present invention, said two projection is that parallel interval is arranged, the one of described projection
End is in closed, and the other end is provided with the opening inserted for described ceramic PTC heating plate.
As a further improvement on the present invention, described heat conduction panel is one near the side of described battery case body
Burnishing surface, described heat conduction panel is fixed by screws on described battery case body.
As a further improvement on the present invention, described ceramic PTC heating plate is the heating plate of positive temperature coefficient.
As a further improvement on the present invention, one end of described electric connection is provided with two joints and is connected to position
In ceramic PTC heating plate in said two projection, the other end is a joint.
As a further improvement on the present invention, adjacent with described heat conduction panel on described battery case body both sides
On wall, the most symmetrical interval is fixed with two hooks.
As a further improvement on the present invention, the both sides, upper end of described battery case body are equipped with an outside folding
Curved, described bending and described heat conduction panel are positioned at the same side of described battery case body.
As a further improvement on the present invention, a sidewall of described battery case body is fixed with one first support
Frame, between described first bracing frame is linked up with at two, with described first bracing frame on described battery case body
To a sidewall on interval be fixed with two the second bracing frames, described second bracing frame is positioned at the outside of hook.
By such scheme, the present invention at least has the advantage that this battery case assisted heating device is by adopting
Auxiliary heating is realized by the heating plate of ceramic positive temperature coefficient, when in heating process, own temperature reaches threshold value,
The resistance of PTC self will steeply rise, and heating power will be caused to decline rapidly and reach temperature-controllable, Ji Keyou
Effect solves the uncontrollable problem of heating plate own temperature, uses heat conductivity higher heat conduction panel attachment battery
Casing, thus there is heat Conduction-temperature evenly, it is to avoid local temperature is too high, it is simple to battery management system
Monitoring, it is ensured that the safety of battery.
