Covestro Makrolon® polycarbonate protects charging stations from the elements

A Worry-free Charge

Electric vehicle (EV) has begun to gain global attention as an attractive form of transportation that has the potential to significantly reduce our dependence on fossil-fuel. Public charging stations are being installed in increasing numbers to serve the growing number of electric vehicles on the road. As the largest and most open electric vehicle charging network in the world, ChargePoint continues to spearhead industry development.

With a long history of cooperation with ChargePoint, Covestro has supported the development of all ChargePoint’s Level 2 charging stations and its new Wallbox, both of which utilize the outstanding material properties of Makrolon® polycarbonate.

Task

Possessing over 15,000 charging stations, ChargePoint accounts for 70 percent of the U.S. market. In order to maintain its leading position, ChargePoint looked for an impact-resistant material that could meet stringent flame retardance ratings while also enabling stylish aesthetics for its charging stations. ChargePoint engineers also wanted to cooperate with a material manufacturer who can offer their expertise in material technology and is experienced in prototype design. After a careful evaluation, the company selected Covestro and its Makrolon® polycarbonate.

Challenge

Charging locations are often setup outside and often in unattended public locations, leaving them vulnerable to severe weather conditions. Therefore, materials that make up the internal and external housings of the charging station need to be durable and durable in order to withstand the in order to withstand inclement weather.

Solution

Makrolon® 6487 polycarbonate is now used for the housing and internals of Level 2 charge stations such as the top cap and plug holsters, while Makrolon® 6557 polycarbonate is used for the front-facing panels. The impact-resistant and flame retardant Makrolon® polycarbonate grades allow for a more affordable, customizable, and intuitive way to charge electric vehicles, making it easier than ever for station owners to get a worry-free charge whether on the road or at home. In addition, Covestro has worked closely with ChargePoint’s engineers to go through multiple iterations before production, helping shorten the time to market and reducing costs of molding and tooling. It is worth mentioning that the ChargePoint Home using Covestro’s materials has won Edison Award for its product innovation and human-centered design.
