Vehicle Mounted Thermal Camera Has Been Performing Well in the Electric Vehicle Industry

The electric vehicle industry is booming, and the regulations and standards are improving day by day. As a non-contact temperature distribution imaging inspection instrument, the vehicle-mounted thermal imaging camera has been used in all aspects of the industry chain.

1. Vehicle-mounted thermal imaging camera battery pack safety testing

According to the relevant requirements, the automotive power battery pack should complete vibration, mechanical shock, drop, flip, simulated collision, extrusion, damp heat cycle, seawater immersion, external fire, salt spray, high altitude, over-temperature protection, short circuit protection, overcharge protection, over-discharge protection and other safety tests. These experiments often take a long time, for example, the temperature shock test requires the battery pack to be in an alternating environment of (-40±2)℃ ~ (85±2)℃, with extreme temperature alternating transitions for 0.5h, maintained in each extreme temperature for 8h, cycled 5 times, and also observed at room temperature for 2h after the test.

The vehicle mounted thermal camera has been performing well in the electric vehicle industry  can observe the temperature distribution on the surface of the battery pack, assist engineers to verify the thermal simulation, cooling, protection and other designs, and discover potential hidden dangers such as shell fatigue, rupture and local overheating that cannot be observed by the naked eye to avoid fire and explosion.

2. The vehicle mounted thermal camera charging pile

Inside the charging pile are a power module, charge controller, billing control unit, high-voltage insulation detection board, display screen, etc. There are also sheet metal parts, fuses, relays, lightning protection and other equipment, which generate huge heat. Take the 60KW charging pile as an example, according to the power module conversion efficiency of 95%, only the power module heat generation reaches 60×0.05×1000=3000W, therefore, heat dissipation and temperature control are the places that must be concerned in the development of the charging pile.

Vehicle mounted thermal cameras play a great role in charging pile R&D, testing, installation and quality inspection.
