Description

Technical Field

[0001] The present invention relates to the technical field of charging facility safety control, and more specifically, to a charging pile emergency stop and reset system. Background Art

[0002] As the world pays more attention to environmental protection and sustainable development, electric vehicles are becoming more and more popular as an important means to reduce carbon emissions and ease energy pressure. As an important supporting facility for electric vehicles, the construction and operation of charging piles are directly related to the charging convenience and user experience of electric vehicles. However, with the surge in the number of charging piles and the diversification of usage scenarios, their safety issues are becoming increasingly prominent.

[0003] In the daily use of charging piles, you may encounter a variety of emergency situations, including but not limited to equipment failure, operating errors, changes in the external environment (such as fire, flooding, etc.) and human damage. If these emergencies are not handled promptly and effectively, they may not only cause damage to the charging piles, but also pose a threat to the surrounding environment and personnel safety. Therefore, how to ensure that the charging piles can quickly cut off the power supply in an emergency to prevent the accident from expanding has become an urgent problem to be solved.

[0004] Traditional charging pile emergency stop functions often use simple mechanical or electrical switches to cut off the power supply through manual operation. However, this method has many shortcomings: first, the response speed is slow and the power supply cannot be cut off immediately; second, the operation is complicated and requires personnel to arrive at the site for operation; third, there is a lack of intelligent control and it is impossible to handle flexibly according to specific circumstances. In addition, the traditional emergency stop function often only has a power-off function, lacks subsequent reset control and remote monitoring capabilities, and is difficult to meet the safety management needs of modern charging facilities.
