What do electric cars mean for spray booths?

Talking about curing paint on electric cars

Many Bodyshop workers have raised the issue that electric cars (batteries) cannot be subjected to high temperatures, as this would be damaging the high-voltage battery used to power the electric motor. Therefore, when drying paint in a heated paint booth, they need to ensure the temperature does not exceed 60° C.

With the growing number of electric cars on the roads in the UK, more and more of them will need a trip to the body shop. Of course, this may result in paint repairs, and the paint will need to be cured.

There are slightly different thresholds of damage by battery chemistry and cell configuration, all batteries, including traditional lead-acid 12-volt batteries, can be damaged by excessive heat. Heat-related damage can result in various outcomes, depending on the temperatures involved and the time of exposure.

Excessive heat can damage many areas of a lithium-ion battery pack in different ways. A typical damage scenario is essentially the degradation of active lithium and other materials in the battery cells resulting in a loss of cell capacity. At the same time, an associated increase of internal electrical resistance can reduce the rate of cell output or power.

Different manufacturers have different assessments of the temperature at which their cars' battery packs are at risk. The duration of the exposure is also essential so that some carmakers will permit higher temperatures for shorter periods or lower temperatures for a longer time.

Either way, this is a risk in the Bodyshop. So how do the Bodyshop's cure the paint on these heat-sensitive cars?

Do they need to turn down the temperature in those paint booth ovens to protect the EVs' batteries, which are susceptible to such extreme heat?

Greentech robot curing paint on an electric car

Todd Engineering has another solution: Greentech Dryers Curing Robots.

The Greentech machinery is equipped with catalytic panels, powered by methane gas or LPG, able to emit a low-intensity uniform heat without producing flame.

The intelligent way the IR technology can focus the curing to the panels on the vehicle instead of warming the complete vehicle means we eliminate the problems associated with the batteries in electric cars.

The impressive thing about the Greentech product is that you will not have to remove your current spray booth. Instead, Todd Engineering can retrofit the equipment into your existing spray booth.

The vast range of models suits every process, from the E1 handheld product to the E8 extended arch for large commercial vehicles. And they come with many other benefits.

Larger booths to cure paint on electric cars

This innovative and convenient technology makes the workflow extremely competitive by improving the drying quality and reducing the environmental impact by 80% compared to traditional systems.

One of the design phase's main goals is to optimise the drying process, which results in perfection, both for the water-based products and the solvent-based products, and to allow sanding and smoothing as soon as the treatment cycle ends.

IR Gas Catalytic Drying offers low environmental impact technology, which can cure all paint products on vehicles faster, better, and cheaper, making it the most reliable and cost-effective equipment on the market.
