Thermal Paste: The New Maintenance Required by Electric Vehicles

Thermal paste is a type of grease that dissipates the heat generated in batteries, preventing overheating and system failures, and it is the new maintenance task for electric vehicles in the workshop.

The arrival of electric vehicles raises many questions for workshops when it comes to performing maintenance, which is significantly less frequent in this type of vehicle due to the much lower number of components. However, while some mechanical tasks disappear, others emerge.

One of the most frequent issues with electric vehicles is related to significant temperature variations—both very cold and very hot—which decisively affect battery range. This limited range is one of the main drawbacks of pure electric vehicles and is a key reason why their adoption in certain countries is progressing more slowly than authorities and manufacturers would like.

To ensure that the battery operates perfectly under adverse weather conditions, there is a key component that did not previously exist in workshop maintenance and operations: thermal paste. It is a type of grease or adhesive that helps dissipate the heat generated in the batteries, as it is an excellent heat conductor. This improves heat transfer between the battery modules and the casing.

Proper maintenance of thermal paste is crucial to prevent the vehicle’s battery from overheating, which would reduce its performance and shorten its lifespan. Likewise, it helps distribute heat evenly, avoiding damage to the electrical components.

It also allows for the optimization of battery performance, preserving energy efficiency. Poor thermal management can lead to efficiency losses, reducing the range of the electric vehicle and affecting its overall performance.

It is important to note that there are many types of thermal paste available on the market. Improper use of this product may void the vehicle’s warranty.

The main recommendation is to use the specific compound recommended by the manufacturer to avoid potential damage to the customer.
