Collection, thereby greatly improving the reliability and stability of charging and discharging operations of electric vehicle battery packs.

Description

technical field [0001] The invention relates to a connection terminal, in particular to a connection terminal structure for a battery pack of an electric vehicle. Background technique [0002] When the battery pack of an electric vehicle is electrically connected to the external power supply circuit and charging circuit, it needs to be connected through terminal blocks. When it is found in actual use, the terminal blocks currently used are often traditional terminal structures. Although It can meet the needs of use, but it lacks protection for the position of the terminal, which can easily lead to pollution and corrosion of the terminal caused by dust, liquid droplets, etc., while affecting the reliability of the connection, and easily lead to a short circuit at the position of the terminal At the same time, it is also very easy to damage the terminal due to external force impact, short circuit and other phenomena, which seriously affect the safety and reliability of the ter...

[0002] When the battery pack of an electric vehicle is electrically connected to the external power supply circuit and charging circuit, it needs to be connected through terminal blocks. When it is found in actual use, the terminal blocks currently used are often traditional terminal structures. Although It can meet the needs of use, but it lacks protection for the position of the terminal, which can easily lead to pollution and corrosion of the terminal caused by dust, liquid droplets, etc., while affecting the reliability of the connection, and easily lead to a short circuit at the position of the terminal At the same time, it is also very easy to damage the terminal due to external force impact, short circuit and other phenomena, which seriously affect the safety and reliability of the terminal operation. In order to overcome this problem, the current main method is to install a The insulating sheath protects the terminal through the insulating sheath. Although it overcomes the influence of pollution and external force impact on the operation of the terminal to a certain extent, the effect is not obvious, and it cannot be used for the temperature of the terminal during operation. , current, voltage and other parameters are effectively detected and collected, resulting in the current operation of electric vehicle equipment, there are still great potential safety hazards in the position of the battery pack terminal, especially when performing fast charging operations and large current discharges. This phenomenon is particularly prominent, so in response to this problem, it is urgent to develop a new terminal structure to meet the needs of actual use.
