Embodiment 1

[0017] figure 1 A schematic diagram of an exploded structure of an electric vehicle power battery box provided by an embodiment of the present invention, such as figure 1 As shown, the electric vehicle power battery box provided by the present invention includes:

[0018] Battery box cover 1, battery box body 3, temperature control module 2 and battery array 4;

[0019] The battery array 4 is fixedly arranged in the battery box 3, the battery array 4 is composed of a plurality of battery modules, and gaps are left between the plurality of battery modules;

[0020] The temperature control module 2 includes a circulation pipeline 202, a fixed plate 201 and a heat dissipation array 203 composed of heat sinks. Each heat sink is fixed on the fixed plate 201 through the circulation pipeline 202. The fixed The plate 201 is embedded on the battery box cover 1; the circulation pipeline 202 is used to transmit the heat transfer fluid medium;

[0021] Each heat sink is inserted betwee...

Embodiment 2

[0031] On the basis of the first embodiment above, the electric vehicle power battery box provided in this embodiment further includes:

[0032] A central control element and a temperature sensor connected to the central control element, the temperature sensor is arranged on the battery box, and the temperature sensor is used to detect the heat dissipation temperature of the battery array;

[0033] The central control element is used for controlling the transmission of the heat transfer fluid medium according to the heat dissipation temperature.

[0034] Specifically, the temperature sensor transmits the temperature information collected from the battery box to the central control component, and the central control component analyzes the received temperature information, and searches for the corresponding control strategy among the preset control strategies according to the analysis results , the central control component controls the temperature of the battery box according t...

Abstract

The invention provides power battery box of an electric car and the electric car. The battery box comprises a battery box cover, a battery box body, a temperature control module and a battery array; the battery array is fixedly arranged in the battery box body, the battery array consists of a plurality of battery modules, and a gap is formed between every two adjacent battery modules; the temperature control module comprises a circulating pipeline, a fixed plate and a heat radiation array consisting of cooling fins, each cooling fin is fixedly arranged on the fixed plate by virtue of the circulating pipeline, and the fixed plate is arranged on the battery box cover; the circulating pipeline is used for transmitting heat conduction fluid medium; each cooling fin is inserted between the corresponding battery modules by virtue of the gap and contacts the corresponding battery modules so as to cool the corresponding battery modules. According to the electric car power battery box and the electric car, the cooling fins of the temperature control module are arranged in the gaps of the battery modules, so that a purpose of controlling the temperature of the battery box can be achieved, the structure is simple, and the temperature adjusting efficiency is relatively high.

Description

technical field [0001] The invention relates to the field of battery boxes, in particular to an electric vehicle power battery box and the electric vehicle. Background technique [0002] With the increase of the number of automobiles, the environmental problems caused by automobiles are becoming more and more serious. In order to alleviate this problem, the research and development and application of electric vehicles have been paid more and more attention. [0003] At present, the core technologies of electric vehicles have been developed rapidly and are close to the level of large-scale application. Among them, in order to ensure the safety and reliability of automobile power batteries, the existing technology integrates temperature control under the automobile power battery box. A systematic approach is used to regulate the temperature of the battery. However, this integration method is more complex and has a lower temperature regulation efficiency. Contents of the inve...
