Problems solved by technology

If the new energy electric vehicle still uses a 250A medium power socket, a 70mm2 dry-type cable and a dry-type conductive jack, during the charging process, if the charging current is greater than 250A, the heat generated by the cable cannot be dissipated well, and it will Accidents caused by overheating, serious cases can cause fires and burn vehicles

Embodiment 1

[0036] At present, the country has standard definitions for electric vehicle charging cables and multiple cables in the charging socket. In addition to the two charging cables DC+ and DC-, there are also multiple weak current cables such as signal lines and communication lines. The present invention Mainly for the DC+ and DC- two charging cables with large charging current and high heat generation.

[0037] figure 1 Shown is a schematic structural diagram of a liquid-cooled cable for a new energy electric vehicle liquid-cooled charging socket of the present invention, including two liquid-cooled jacks 1, DC+ and DC-, arranged in the charging socket of an electric vehicle, and also includes a battery pack Two liquid-cooled electrodes 2 connected to DC+ and DC- poles, and two electrodes respectively connected between DC+ liquid-cooled jack 1 and DC+ liquid-cooled electrode 2, DC-liquid-cooled jack 1 and DC-liquid-cooled electrode 2 A liquid-cooled cable3. Wherein, the liquid-c...

Embodiment 2

[0055] As described in Embodiment 1, the liquid-cooled cable for the liquid-cooled charging socket of a new energy electric vehicle is different from Embodiment 1 in that: Figure 9 As shown, the flexible wire 3.3 runs through the insulating sleeve 3.5, and the cooling liquid inner tube 3.4 is also installed in the insulating sleeve 3.5. The inner cavity of the cooling liquid inner tube 3.4 is the cooling liquid inner channel 3.1, and the cooling liquid inner The cavity between the tube 3.4 and the insulating sleeve 3.5 is the cooling liquid outer channel 3.2. One end of the cooling liquid internal channel 3.1 connected to the liquid-cooled electrode 2 is connected to the liquid inlet 2.1, and one end connected to the liquid-cooled jack 1 is connected to the communication cavity 1.1. One end of the cooling liquid outer channel 3.2 connected to the liquid-cooled electrode 2 is connected to the liquid outlet 2.2, and one end connected to the liquid-cooled jack 1 is connected to ...

Abstract

A cooling method of a liquid-cooled cable for a liquid-cooled charging socket of a new energy electric vehicle, including two liquid-cooled jacks, DC+ and DC-, which are arranged in the charging socket of an electric vehicle, and also include DC+, DC-poles connected to the battery pack Two liquid-cooled electrodes connected, and two liquid-cooled cables respectively connected between the DC+ liquid-cooled socket and the DC+ liquid-cooled electrode, and between the DC-liquid-cooled socket and the DC-liquid-cooled electrode. The liquid-cooled cable includes a flexible wire for conducting electricity, and is used for cooling the coolant inner channel and the coolant outer channel of the liquid-cooled cable; the ends of the coolant inner channel and the coolant outer channel connected to the liquid-cooled electrode are respectively connected The liquid inlet and the liquid outlet are in communication, and the end connected to the liquid cooling jack is in communication with the communication chamber. The present invention increases the current carried by the charging cable from the existing 250A to 600A without increasing the diameter of the existing cable, and can ensure that the temperature rise of the charging cable is within a controllable range. Requirements for charging time of electric vehicles.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a liquid-cooled cable for a liquid-cooled charging socket of a new energy electric vehicle. Background technique [0002] New energy electric vehicles have been rapidly developed because they have no exhaust emissions and do not pollute the environment. At present, there are two main factors restricting the development of new energy electric vehicles: one is the short battery life; the other is the long charging time. Taking electric bus charging as an example, the most powerful charging pile currently used is a medium-power DC charging pile. Its charging voltage is DC 750 volts, and the maximum output charging current is DC 250A. The battery of an electric bus needs at least 2 to 3 hours. However, since the charging socket on an electric vehicle is usually installed on the body shell, and the battery is placed in the car body, two 70 square millimeter dry cab...
