The extra care needed when spraying electric vehicles
June 10, 2022
There is the potential for automotive spray booths to struggle with paint repairs on electric vehicles. Electric vehicles cannot be finished in high-temperature paint booths due to the powerful battery. Auto manufacturers, including Audi, Lexus, Tesla, Toyota, and Volvo, have issued comments stating that electrical vehicle drying temperatures should not exceed 50 degrees centigrade (120 degree Fahrenheit).
With the increasing number of electric vehicles on UK roads, more and more will require a trip to the body shop. Of course, this will necessitate paint repairs and the curing of the paint.
Although battery chemistry and cell structure have slightly varied damage thresholds, all batteries, including typical lead-acid 12-volt batteries, can be harmed by extreme heat. Depending on the temperatures involved and the length of exposure, heat-related harm can have a variety of results.
Spray booth safety when spraying electric vehicles
Because electric vehicles can’t be cured in a traditional cure cycle, technicians usually utilise a long, lower temperature cure. This doubles the bake time, lowering overall throughput and slowing down a shop dramatically, it also incurs increased energy costs per bake cycle.
Excessive heat has the potential to harm a lithium-ion battery pack in a number of ways. The deterioration of active lithium and other components in battery cells, which results in a loss of cell capacity, is a common damage scenario. An increase in internal electrical resistance can reduce the rate of cell production or power at the same time.
When operating on electric vehicles, technicians must isolate the high-voltage system for their own safety. Because the capacitor’s cooling system is disabled, the car is vulnerable to overheating.
Short-wave infrared electric curing technologies are the best way to treat electric vehicles without causing damage or lowering spraybooth performance. This process heats and cures the coating from the inside out by directly penetrating the substrate surface, whether it’s metal, plastic, or another material.
