They had a basic design of the type of brush they were looking for; however, they needed specific expertise in order to determine how this unique design could be manufactured and a material that would satisfy their performance requirements. **Industry:** Electric Vehicle Supply Equipment **Product Needed**: Brushes **Product Application**: Slip Ring for Electric Car Charging **Materials & Grade Used**: Wire and Carbon Graphite Brushes   ![controled-module-featured](https://knowledge.stmaryscarbon.com/hubfs/controled-module-featured.webp "controled-module-featured") ## PROCESS & PROJECT SUMMARY Given this was a new design, our [Product Development](https://www.stmaryscarbon.com/customized-product-solutions/?__hstc=45788219.6006e26bb71771b65fc1416521976dcc.1749193953428.1749193953428.1749193953428.1&__hssc=45788219.1.1749193953428&__hsfp=1412063329) and Engineering departments worked to find a grade that would suit their application. After reviewing and testing several grades, it was determined that **SMC grade G364** would be a perfect fit for their application. We believed this grade would provide them with the required performance characteristics (e.g., [electrical conductivity](https://www.stmaryscarbon.com/application/electrical-transmission/?__hstc=45788219.6006e26bb71771b65fc1416521976dcc.1749193953428.1749193953428.1749193953428.1&__hssc=45788219.1.1749193953428&__hsfp=1412063329), [temperature](https://www.stmaryscarbon.com/application/high-temperatures/?__hstc=45788219.6006e26bb71771b65fc1416521976dcc.1749193953428.1749193953428.1749193953428.1&__hssc=45788219.1.1749193953428&__hsfp=1412063329)) and also address the dusting, marring and galling issues they experienced with other materials they had previously tested. So as not to hold up their production cycle, we further expedited the testing process by sending them samples of the material and wire so they could assemble them quickly themselves and start to test immediately. Based on the testing, they were incredibly pleased with the results of the brush and as such, they were able to finalize the drawing and we are now collaborating with them to produce these brushes as part of their production cycle. ![Picture2-175x300-1](https://knowledge.stmaryscarbon.com/hs-fs/hubfs/Picture2-175x300-1.png?width=175&name=Picture2-175x300-1.png) ![control-module-3-174x300-1](https://knowledge.stmaryscarbon.com/hs-fs/hubfs/control-module-3-174x300-1.png?width=174&name=control-module-3-174x300-1.png) ![control-module-1-174x300-1](https://knowledge.stmaryscarbon.com/hs-fs/hubfs/control-module-1-174x300-1.png?width=174&name=control-module-1-174x300-1.png) ### SIGN UP TO GET OUR NEWEST BLOGPOSTS IN YOUR INBOX ### Contact 259 Eberl Street, St. Marys, Pennsylvania 15857 Phone: 814.781.7333 – Fax: 814.834.9201 [info@stmaryscarbon.com](mailto:info@stmaryscarbon.com) ### Get Social - Facebook   - Twitter   - Google+   - LinkedIn   Copyright © 2024 St Marys Carbon – All Rights Reserved ```json { "@context" : "https://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "St Marys Carbon", "url" : "https://knowledge.stmaryscarbon.com/author/st-marys-carbon" }, "dateModified" : "2025-06-06T07:14:37.951Z", "datePublished" : "2017-07-25T12:56:00.000Z", "headline" : "Electric Vehicle Brushes for Slip Rings", "image" : [ "https://knowledge.stmaryscarbon.com/hubfs/controled-module-featured.jpg" ], "mainEntityOfPage" : { "@id" : "https://knowledge.stmaryscarbon.com/electric-vehicle-control-module", "@type" : "WebPage" }, "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "url" : "https://knowledge.stmaryscarbon.com/hubfs/smc_logo-1.svg" }, "name" : "St Marys Carbon Co" } } ```
