TECHNICAL FIELD

[0001] The utility model relates to mobile charging car technical field especially relates to a mobile charging car battery safety protection module. BACKGROUND

[0002] With the sustained development of new energy vehicles, the endurance problem of new energy vehicles is increasingly prominent. At present, in order to solve the endurance of new energy vehicles, the practical application scheme has two ways of charging station and battery swap station. However, the charging station still has the following problems: if the charging station is large, it needs to occupy a certain site, which makes the charging station cost higher, especially in urban centers and other sites; if the charging station is small, it will not be able to meet the demand because of the small number of charging piles. In addition, for electric vehicles, there is also a situation that cannot reach the charging station before the power is exhausted due to battery problems or error estimation of remaining mileage. In this case, mobile charging trolley emerges as the times require.

[0003] The mobile charging trolley needs to charge the new energy vehicle quickly in the shortest time, so it can only use direct current fast charging technology. However, whether it is high voltage or increased current, it needs to face not small safety risk, and the battery on the mobile charging trolley may also self-ignite under the influence of high temperature or other factors. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a mobile charging car battery safety protection module to solve the problems existing in the prior art.

[0005] The above technical purpose of the utility model is realized by the following technical scheme:

[0007] The monitoring system comprises a control module, a communication module, a temperature detection module and a power detection module, the control module is arranged in the interior of the mobile vehicle, the output end of the control module is electrically connected with the input end of the communication module through an electric wire, the communication module is connected with the first foaming device through an electric signal, and the communication module is connected with the second foaming device through an electric signal, the output end of the temperature detection module is electrically connected with the input end of the control module through an electric wire, and the output end of the power detection module is electrically connected with the input end of the control module through an electric wire, the temperature detection module is used for detecting the temperature of the charging group during work, and the power detection module is used for detecting the power of the charging group during work.

[0008] By adopting the above technical scheme, the isolation device composed of multiple partitions can accommodate multiple batteries in independent spaces, if a safety accident occurs and the batteries start to burn, there will be no chain reaction to affect other normal working batteries that have not caught fire, and the fire-retardant layer on the partition can effectively reduce the speed of flame spread, and after the fire occurs, the temperature detection module in the monitoring system will immediately alarm, so that the first foaming device and the second foaming device start to continuously inject the foam extinguishing agent into the interior of the partition through multiple second through holes, in addition to the top layer and the bottom layer of the isolation device adjacent to the foaming device, there are first through holes between different batteries as connections, therefore the foaming device will inject the foam extinguishing agent into the surroundings of each battery through the first through holes until the battery is filled, at the same time, the power detection module in the monitoring system can detect the power of the power supply, if some abnormalities occur, the danger can be detected in advance, and the power is reduced and an alarm is sent to remotely solve or notify the on-site workers to solve.

[0009] In further embodiments, a liquid cooling device is fixedly installed in the mobile vehicle, the liquid cooling device comprises a circulating liquid loop and a cooling liquid loop, one side of the liquid cooling device is provided with a cooling outlet, a cooling inlet is arranged below the cooling outlet at intervals, one end of a cooling hose is detachably installed at the cooling outlet, the other end of the cooling hose is detachably installed at the cooling inlet, and the two ends of the cooling hose are provided with telescopic portions.

[0010] By adopting the above technical scheme, the liquid cooling device has a circulating liquid loop for self-circulation, which functions to take away the waste heat on the cooling liquid loop, and the cooling liquid loop is used to take away the waste heat generated during the charging process, the waste heat can also be taken away by additionally adding a waste heat collecting device to improve the endurance of the mobile charging vehicle, but this will increase the cost, so a corresponding trade-off is needed, and it is feasible whether the waste heat collecting device is added or not.

[0011] In a further embodiment, one end of the charging cable is provided on one side of the charging group, the other end of the charging cable is provided with a charging gun, the outer side of the charging cable is provided with a spiral fin structure, the spiral fin structure is detachably installed in the containing groove formed by the charging cable, a plurality of fixed knots are equidistantly sleeved on the cooling hose, and the fixed knots are used to fix the charging cable and the cooling hose.

[0012] By adopting the above technical scheme, the problem of heat generation of the high-voltage fast-charging wire harness is a common problem of all charging equipment, and the existing solution is to arrange a heat dissipation pipe in the wire harness. However, in fact, this heat dissipation mode has limitations and cannot well dissipate the rapidly accumulated heat. The spiral fin pipe increases the contact area with the outside, and the cooling hose wound on the charging cable can rapidly reduce the heat, thereby effectively improving the cooling efficiency.

[0013] In a further embodiment, the inside of the charging cable is filled with a heat-conducting insulating material.

[0014] By adopting the above technical scheme, the heat-conducting insulating material can increase the external contact area of the wire harness and the cable, and due to good heat conductivity, it will not affect heat dissipation, can make the heat conduct away faster, and can also provide certain insulation effect to avoid safety accidents.

[0016] By adopting the above technical scheme, in the case of spontaneous combustion, the most extreme case is considered, that is, the foaming device fails to operate normally or fails to stop the burning spread of most batteries. In this case, if the charging group explodes in the interior of the charging vehicle, the entire charging vehicle will be damaged, and the charging vehicle itself is also driven by new energy, so its battery may also cause further harm. Therefore, the battery pack needs to be quickly thrown out of the charging vehicle, so as to be far away as soon as possible.

[0017] In a further embodiment, an audible and visual alarm device is arranged on the isolation device, and the audible and visual alarm device is linked with the first foaming device and the second foaming device.

[0018] Through adoption of the above technical scheme, the power supply and the charging group of the sound-light alarm device are linked, and the sound-light alarm device itself is internally provided with certain energy storage elements, so that even if the charging group line is damaged and fails to function, the sound-light alarm device can still maintain operation for a period of time and give sufficient warning and reminder in this period of time.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. Through the setting of the isolation device, the isolation device composed of multiple partitions can install multiple batteries in independent spaces. If a safety accident occurs and the batteries start to burn, it will not cause a chain reaction to affect other normal working batteries that have not caught fire. The fire-retardant layer on the partition can effectively reduce the speed of flame spread. After a fire occurs, the temperature detection module in the monitoring system will immediately alarm, causing the first and second foaming devices to start and continuously inject foam extinguishing agent into the interior of the partition through multiple second through holes. In addition to the top and bottom isolation devices adjacent to the foaming device, there are first through holes between different batteries as connections. Therefore, the foaming device will inject foam extinguishing agent around each battery through the first through holes until it is filled. At the same time, the power detection module in the monitoring system can detect the power of the power supply. If some abnormalities occur, it can detect the danger in advance. By reducing the power and issuing an alarm, the effect of remotely solving or notifying the on-site staff to solve the problem is achieved.

[0021] 2. Through the setting of the spiral fin structure and the cooling hose, the contact area of heat with the outside is increased, and the cooling hose wound on the charging cable is used to quickly reduce heat, effectively improving the cooling efficiency. The thermally conductive insulating material filled inside can increase the external contact area of the heat-generating wire harness and the protective cable. At the same time, due to good thermal conductivity, it will not affect heat dissipation, allowing heat to be conducted away more quickly. It also provides certain insulation effect to avoid safety accidents.

[0022] 3. Through the setting of the linear guide rail and the auxiliary guide rail, in the event of spontaneous combustion, the most extreme case is considered, i.e., the foaming device fails to operate normally or fails to stop the majority of batteries from being burned. In this case, if the charging group explodes inside the charging vehicle, the entire charging vehicle will be damaged. The charging vehicle itself is also driven by new energy, so its battery may cause further harm. Therefore, the battery pack needs to be quickly thrown out of the charging vehicle to quickly move away. The power supply and the charging group of the sound-light alarm device are linked, and the sound-light alarm device itself is internally provided with certain energy storage elements. Even if the charging group line is damaged and fails to function, the sound-light alarm device can still maintain operation for a period of time and give sufficient warning and reminder in this period of time.
