Description

Technical Field

[0001] The present invention specifically relates to the technical field of battery detection, and in particular to a battery safety detection device for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new on-board power devices), and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures.

[0003] New energy vehicles include four major categories: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including new energy vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels, and other high-efficiency energy storage devices). Unconventional vehicle fuels refer to fuels other than gasoline and diesel.

[0004] As the photovoltaic and solar thermal power generation industries mature, the application of new energy batteries is becoming increasingly widespread. New energy battery panels consist of a cover plate, battery cells, and a back plate. The back plate protects and supports the battery cells. Compared to traditional new energy battery panels using resin back plates, new energy battery panels using glass back plates offer higher reliability and durability, and are also more resistant to high temperatures and humid environments.

[0005] Two holes are required on the backplane of a new energy battery to allow access to the positive and negative electrodes. In industrial production, drilling machines are used to drill holes in new energy glass backplanes. After drilling, the glass backplanes are directly fed into the automated production line for line cleaning, assembly, and lamination. This means that any issues with drilling quality may not be discovered until lamination is complete. Since laminators process substrates in batches, any defects detected by the laminator will result in the entire batch being scrapped, resulting in significant financial losses.
