Problems solved by technology

[0004] However, since the air inlet of the existing power battery system is always connected with the passenger compartment, the following problems will occur: when special conditions such as overcharge, overdischarge, or internal short circuit of the battery cell in the power battery system occur, it is very easy to A large amount of toxic and harmful substances are produced, and these toxic and harmful substances will quickly invade the passenger compartment from the air inlet of the air-cooled power battery system along the pipeline, causing poisoning or suffocation of the occupants, and affecting the safety of the car

[0056] Such as figure 1 As shown, the automobile A of this embodiment includes: a passenger compartment 1; an air-conditioning system (not shown), used to send cold air to the passenger compartment 1; an air-cooled power battery system 2; a pipeline 3, and a port communicates with the passenger compartment 1 , and the other port leads to the air inlet (not marked) of the air-cooled power battery system 2 . Wherein, the air-cooled power battery system 2 includes: a safety protection device 20 for switching the open and closed states of the air inlet of the air-cooled power battery system 2 .

[0057] Such as figure 2 As shown, the safety protection device includes: a damper 21, located at the air inlet; a transmission part 22, fixedly connected with the damper 21; a driving part 23, connected with the transmission part 22, and used to drive the movement of the damper 21; a first power supply 24, The switch 25 is electrically connected to the driving part 23. When the switch ...

[0085] One of the differences between the second embodiment and the first embodiment is that in the second embodiment, as Figure 5 As shown, the information judging unit 28 is also used to control the switch 25 to be turned on based on the temperature information acquired by the information collecting unit 26 when it is judged that the battery is operating normally, so as to drive the damper 21 to move from the current open position to the set position. For the open position, the higher the temperature acquired by the information collection unit 26 is, the greater the opening amount of the damper 21 is at the set open position of the damper 21 .

[0086] In other words, in the second embodiment, when the battery in the air-cooled power battery system is operating normally, the information judging unit 28 will adjust the opening amount of the damper 21 according to the temperature acquired by the information collection unit 26, so that the opening amount of the damper 21 Adapt...

Abstract

An automobile and an air cooling power battery system therefor are disclosed. The air cooling power battery system comprises a safety protection apparatus, wherein the safety protection apparatus is used for judging operating states of the battery according to working state information of the operating battery in the battery system; the working state information is obtained by an information collection unit and processed by an information processing unit; when an abnormal operation of the battery is judged, an information judging unit controls an air door to switch from an open state into a closed state to enable the air inlet of the battery system to switch from an open state into a closed state so as to enable a passenger compartment to be insulated from the air inlet and to prevent toxic and harmful substances generated by the battery system from entering the passenger compartment through a pipeline, so that the safety of the automobile in use is improved; and when a normal operation of the battery is judged, the air inlet is kept open to enable the passenger compartment to be communicated with the air inlet, so as to enable the cold air from an air conditioning system to the passenger compartment to sequentially pass through the pipeline and the air inlet and then to enter the interior of the air-cooling power battery system, so that the heat generated by the air-cooling power battery system is taken away, and the battery system is cooled.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle and an air-cooled power battery system thereof. Background technique [0002] With the increasingly severe energy and environmental problems, new energy vehicles have emerged as the times require. Some new energy vehicles (such as pure electric vehicles, gasoline-electric hybrid vehicles) use a power battery system as the power source of the vehicle. The power battery system is a key component related to the performance of the vehicle, and its temperature characteristics directly affect the performance, life and durability of the vehicle. The power battery system will generate heat when it is working, and the heat generated is a factor that causes the power battery system to be unsafe. Therefore, the power battery system needs to be cooled. [0003] The cooling methods of the existing power battery system are divided into two types: air cooling and liquid ...
